Fig. 4-1 Connection example between camera
and peripheral devices
4. How to Operate
(4-1) Connection method
●Connection
Refer to the connection example between the camera and peripheral devices (Fig. 4-1).
(1) Remove the cover of the lens attachment section and
attach a lens (option).
(2) Connect the camera head to a power supply
unit(option) with a camera cable (option).
The maximum allowable length for TAKENAKA SYSTEM
standard camera cable(6P12G-series) is 20 m.
(3) Set the camera operation modes in accordance with the
setting instructions for the operation modes and the shutter
speed that are described in another section.
(4) Connect the digital output connectors on the rear of the
camera to the input terminals of the image processing units
(frame grabber board, computer, etc.) with digital cables
(option) conforming to Camera Link . The maximum
allowable length between the digital output connector of
the camera and the input terminal of said image processing
unit is 10 m.
(5)Confirm the connecting condition before turning on the power switch
of the camera. In 1 or 2 seconds after the power is turned on, the LED operation indicator on the rear panel of the
camera changes from orange to green to show that the camera is in operation.
(Note) The maximum allowable lengths of the camera cable and the digital cable aforementioned are not for the purpose
of guaranteeing the operation of the camera. Proper image signals may not be obtained even when the cables are
within the allowable ranges, depending on the installation conditions of the camera, cables in use and others.
●Application of test pattern
This equipment has the function of generating test patterns. This test pattern allows the user to confirm the
appropriateness of the connection between the camera and PC as well as the setting of the board to some extent
when used during the initial setup process for the connection with the capture board and others.
[Important]
(Note) Make sure to turn off the power switch of the camera before connecting or disconnecting the camera cable.
If the cable is connected or disconnected while the power is supplied, troubles may be caused.
(Note) Make sure to turn off the camera and connected devices in advance when the camera is connected.
(Note) When a power supply unit other than Takenaka’s camera power supply units that are separately sold is used, make sure
that it complies with the following rated specifications:
Power supply voltage: DC12V±10%
Current capacity: 900mA or over (recommended value)
Take into consideration the fact that transient current of about 1.5A flows when power is applied.
Ripple voltage: 50mVp-p or less (recommended value)
Connector: 6 pin connector 1 pin (GND), 6 pin (+12VDC)
(Note) Some power supply units other than TAKENAKA’s products have different layout of power connection pins. Make sure to
check the compatibility of the power supply unit and the camera connection pins in advance.
Carefully note that any failure associated with power application to out-of-specification pins and others is subject to
charged repair.
(4-2) Input of Vinit signal (asynchronous trigger signal)
●How to input Vinit signal
If the camera is used in the asynchronous shutter mode, the Vinit signal (asynchronous trigger signal) must be input
from the user unit. The Vinit signal is input from Pin (4) of the “POWER”connector (6 pin connector) on the rear of the
camera, or is input as the CC1 signal of the “Camera Link”connector.
If the camera is connected to the power supply unit PU100 with a Takenaka’s 6P12G series cable, connect the Vinit
signal (asynchronous trigger signal) to the trigger input terminal of the power supply unit (PU100).
(Note) OR operation (negative OR) is implemented inside the camera between the Vinit1 input signal of “POWER”
connector and Vinit2 input signal as CC1 signal of “Camera Link” connector.
If either one of those are fixed to the active level, the Vinit signal (logical sum) is also fixed to the H level and the
trailing edge signal cannot be obtained. This would result in failure in starting up the asynchronous shutter
operation. Make sure to fix the input signal on the unused side to the non active level, keep it at high impedance
level or open state (no connection).

●LED indicator for Vinit signal monitoring
When this camera is set in the asynchronous shutter mode, the LED
indicator on the rear panel of the camera lights up in red for one shot in
response to the input of the external trigger signal (Vinit signal).
This allows the user to confirm the state of signal input.
The LED lights up in red for a certain period of time (for about 100 ms)
each time upon detection of a trailing edge of the trigger signal. If a
following trigger signal is input within this period, the lighting time of the
LED will be retriggered and extended.
Since the lighting of the LED responses only to the trailing edge of the
trigger input, it lights up only once for 100 ms even if the trigger input
pulse duration is longer than the one shot time of period.
●Setting of various asynchronous shutter modes
Set the parameters and others in accordance with the following table:
Table 4-1 Setting of various asynchronous shutter modes

Remark

Shutter switch = 1 to 8: same as preset shutter
(Note) When shutter switch is 0, “Continuous image output(no shutter)”is applied for the all.
(Note) For setting methods for the respective parameters of “PWC”and others →See “How to set operation mode”.
●Recommended timing of asynchronous shutter trigger signal (Vinit signal) for preset shutter/pulse width control
For the case of preset shutter mode, the negative logic pulse is applied
within the width range from 1 H (1 horizontal synchronous interval) to 40H
as described below.
For this case, the exposure operation starts in synchronization with the
trailing edge of the applied pulse.
For the case of the pulse width control exposure mode, numeric value of
the L level interval of the input Vinit pulse (shown as Tvinit in the figure) is
retrieved in synchronization with the trailing edge of the internal HD
pulse, and the integer multiple number of H (1 horizontal synchronous
interval) that is closest to the retrieved Vinit pulse duration is transmitted as
nH to the inside of the camera. Then the shutter speed is determined in
response to the time nH.
Vinit
Tvinit
[For the case of preset shutter mode]
1H Tvinit 40H
(The exposure time is independent of the Vinit width.)
1H=1 horizontal scan time
[For the case of pulse width control mode]
(Where PWC=ENABLED, shutter switch = 9)
nH Tvinit <(n+1)H (n is 1 or larger integer.)
(This is the pulse width where shutter exposure time
=nH)
Fig.4-3 Vinit signal timing
(Note) In the pulse width control, the shutter exposure time is almost equal to the integral multiple number of the
horizontal synchronous time (H) that is closest to the Vinit pulse duration. More specifically, however, the
shutter exposure time is indefinite for the time period corresponding to 1H width in the case of normal external
trigger input (or the case where the Vinit signal is not in synchronization with the horizontal synchronous
timing of the camera).
→Refer to the timing chart described in another section for the details.
(Note) When the shutter exposure time is too long in the pulse width control mode, the S/N ratio of the image will
be degraded due to the reduction of dynamic range of CCD, accumulation of thermal noise components of
CCD image sensor in proportion to the shutter speed and other factors. Therefore, if a long exposure time is
employed, it is recommended to conduct experiments using realistic exposure times in actual conditions to
check for the appropriateness.

●Polarity reversal of Vinit2 input
The input polarity of the trigger signal (Vinit2) to be applied via CC1 of Camera Link can be inverted.
Some capture boards may have the polarity of the trigger signal input from CC1 that is fixed to positive logic (L level at
normal/H level at active), which is not compatible with the trigger signal of negative logic input (factory preset polarity
of this equipment). In this case, the input polarity of the trigger signal (Vinit2) via CC1 can be inverted to change from
negative to positive logic by the setting of the camera.
→Refer to “(6-3) How to set operation mode”for the specific setting method.
(Note) The setting of the polarity reversal is valid only for Vinit2. The input polarity of Vinit1 is always negative logic
regardless of this setting.

(4-3) Strobe signal output circuit
It is able to adjust the light emitting timing of external strobe light to the exposure time of the camera.
This signal can be output in the continuous shutter mode as well as in the asynchronous shutter mode.
●Strobe signal output circuit
The signal output terminal is used both for strobe signal (STRB)
and busy (BUSY) signal.
Select any of OFF (Default: H level fixed), STRB and BUSY in
configuration setting.
→Refer to the setting of STRBC0 and STRBC1 in (6-5) Internal flag register
and configuration register
[output voltage range]
(!) The factory default is set to OFF for this camera.
It is required to set STRBC0 flag and STRBC1 flag when outputting STRB or BUSY signal,
●Output signal switching at strobe signal terminal
The signal from this terminal is set to OFF
as a factory default value.
This can be changed to STRB (Strobe timing
signal) or BUSY state by way of rewriting the
configuration register(CR) with serial communication commands.
(CR5) and (CR6) correspond to STRBC0 and STRBC1, respectively
●Strobe signal in continuous shutter mode
This equipment is capable of outputting the strobe signal even in the continuous shutter mode as well as in the
asynchronous shutter mode when the setting is changed to output the strobe timing signal(STRB).
[Explanation] Usage of strobe signal in continuous shutter mode
In the continuous shutter mode, only the incoming light for the time matching the exposure time of the camera is valid.
Accordingly, when a lighting unit is used in the continuous lighting mode, the lighting during the time other than this exposure time
period would be wasted.
Since this equipment is capable of outputting strobe signal (STRB) even in the continuous shutter mode, this output is used as a
trigger signal to control a LED light or other lighting units that can be turned on and off at high frequencies, which helps eliminating
the lighting during the useless lighting time.
The following benefits are derived from this type of lighting control:
●The consumption of the power to a light can be saved by way of lighting only during the valid time for exposure.
●The occurrence of smear is reduced because no light enters any time other than the exposure time periods.
(Note) When the strobe signal is used in the continuous shutter mode to make ON/OFF control on a lighting source unit,
the following must be taken into consideration:
Wherever possible, use a strobe lighting unit or others that are equipped with a power source separated from that
of the camera (electrically isolated power source) and a trigger input terminal (photo coupler input, etc.). If a
lighting unit that shares a power source or a ground circuit with the camera is turned on or off by the strobe signal,
the image output from the camera may have noise due to the influence of the fluctuation of the power supply
voltage or change in the electric potential that occurs at the ON/OFF timing.
Even when the insulation aforementioned is applied, the electromagnetic induction may lead to the occurrence of
noise on the image signal if the electric current of the lighting unit to be control is large. In this case, a measure
must be introduced to reduce electromagnetic induction noise arising from the lighting unit.
(4-4) Test pattern display function
When initially connecting this camera to an image capture board, the use of the test pattern display
function of the equipment makes it easier to confirm that the output timing of the camera and the
details of the signal connection match the particulars of the capture board.
When the test pattern function is set to be ON, the image sensor outputs the test pattern in place of
pictures as shown on the right.
As for this pattern, a numerical value of 1 is simply added in an incremental manner for every
horizontal pixel, and a saw-tooth profile is shown in the range from the numerical value of 0 to 1023.
(Note) In the data, a numerical value of 1 is incrementally added for every horizontal pixel in the
range of 0 to 1023 for the case of 10 bit output, and in the range
of 0 to 255 for the case of 8 bit output.
(Note) The value does not start with 0 at the edge of the effective image area.

(Note) The output values of the test pattern are not affected by the values of the gain setting or offset setting of the
camera.
The default setting is OFF. This setting can be changed on the configuration menu (Operation Mode Setting Group 4) or
by way of rewriting the configuration register with serial communication command.
[Procedure for switching test pattern output ON/OFF]
(1) Start up in the Setting group 4.( Set the mode switch to the position “D”, keeping the power to the camera off. Then
turn on the power of the camera while turning and keeping the UP/DOWN switch lever to the either of upper or lower
position).
(2) Return the UP/DOWN switch lever to the neutral position when the response sound of “pip-pip”is heard
(3) Change the position of the mode switch to “2”after confirming that LED indicator flashes in orange.
(4) The test pattern display gets ON by stroking UP/DOWN switch upward and gets OFF by stroking that downward.
(5) Switch to OFF when Test pattern is not necessary anymore. Since the setting of the test pattern output is
automatically saved, the test pattern will be output with last setting when the power is reapplied from next time.
(4-5) Monitoring function for internal temperature of camera
This camera is equipped with an internal temperature sensor to monitor the temperature inside the body. This function
makes it possible to use the camera in a safer way even in a harsh environment in terms of temperature, for example use
in the open air. With the use of serial communication commands, this function also works to control the forced air-cooling
fan of the camera and peripheral devices and others.
●How to monitor internal temperature of camera
The following two methods are available for monitoring the internal temperature of the camera:
●Turn on the MENU display and confirm on the OSD over the image. (Temperature to be displayed in Celsius)
●Confirm with temperature data to be returned in response to the serial communication command (”RTMP”
command). (Numerical conversion required separately)
(Note) Carefully note that the temperature data obtained by this monitoring function is not for the ambient temperature but
the internal temperature of the camera. As a general rule, the internal temperature of the camera is higher than the
ambient temperature because of the heat generation associated with the consumed electric power inside the
camera.
Even when the temperature monitored by this function exceeds the value of the “Operation ambient temperature”
shown in the specifications of the camera, no operational trouble will be caused as long as the ambient
temperature is equal to the one of the specifications or lower, and sufficient countermeasures against temperature
are taken.
●Detection capability for temperature data
Minimum unit for temperature data : 0.5°
Data refreshing cycle : 0.4 sec.
Temperature detection accuracy: ±2°C (-40°C to +85°C), +3 to -2°C (55°C to 125°C)
Effective data range : -55°C to 125°C (as long as the operation ambient temperature of the camera is
within the range defined by the specifications.)
●Temperature data by serial communication
The temperature data to be returned in response to the “RTMP” command of serial communication is generated in the
following format:
[Data format]
The lower 10 bits out of the 16 bits of the returned data are valid.
XXXXXD9D8…D0 (invalid upper 6 bits/valid lower 10 bits as the data)
Db=B’D9D8…D0 in the binary system shows a signed integer value in two’s complement form.
However, the effective range of the temperature data is limited to the following due to the operational restriction of the
temperature sensor:
Effective range of temperature data: -110 (-55°C) to +250 (125°C)
(Note) The accuracy of the values of the temperature data is not guaranteed when the operation ambient temperature is
not within the range defined by the specifications.
[Conversion method from returned data to temperature in Celsius]
The temperature in Celsius is computed as Tc from the following formula where Dt is the signed integer number converted
from the above described 10 bit binary value of “Db=B’D9D8…D0”:
Internal temperature of camera: Tc=Dt×0.5°C
(Example 1) Where Td, the returned value of the temperature data, is “H’0032” in the hexadecimal system, it is
expressed in the binary system as follows:
Td=H’0032=B’0000.0000.0011.0010
Db=B’00.0011.0010 =+50 (Only upper 10 digits of Td are valid.)
Then, Tc is calculated from the following formula: Tc=+50×0.5°C=+25°C

K12703 ; 11/43
- 11 -
(Example 2) Where Td, the returned value of the temperature data, is “H’03FA” in the hexadecimal system, it is
expressed in the binary system as follows:
Td=H’03F1=B’0000.0011.1111.1010
Db=B’11.1111.1010 (Only upper 10 digits of Td are valid.) → Dt=-6
Then, Tc is calculated from the following formula: Tc=Dt×0.5°C=-6×0.5°C=-3°C
(4-6) Operation confirmation buzzer
This equipment is designed to sound the confirmation buzzer of “pip”when a stroke is applied to the UP/DOWN switch on
the rear panel, or at the time of other manipulation including the start-up after power application.
The factory default setting is ON. This setting can be changed to cancel the buzzer.
[Procedure for switching buzzer between ON/OFF]
(1) Start up in the Setting group 3.( Set the mode switch to the position “C”, keeping the power to the camera off. Then
turn on the power of the camera while turning and keeping the UP/DOWN switch lever to the either of upper or lower
position).
(2) Return the UP/DOWN switch lever to the neutral position when the response sound of “pip-pip”is heard
(3) Change the position of the mode switch to “2”after confirming that LED indicator flashes in orange.
(4) The buzzer sound gets ON by stroking UP/DOWN switch upward and gets OFF by stroking that downward.
(5) Turn off the power following the completion of setting . Since the setting is automatically saved, the camera starts up
with the last setting when the power is reapplied from next time.
(4-7) Camera ID saving function
The ID code and other information set by the user for each camera can be stored in the camera and be read out when
needed. The saved identification data for each camera including installation location in the case of using more than one
camera (e.g., “CAMERA-RIGHT” and “CAMERA-LEFT”) allows the user to easily control and identify the camera (s).
The setting is executed through the serial communication. The settable maximum number of characters are 15, and
alphabets (both upper and lower cases), numbers and some special symbols such as”+” and “-”excluding the control
codes can be used.
(→ Refer to the section of “Serial Communication Control”for the details.)
(4-8) Auto Level Control function (ALC)
The CCD in this equipment has 4ch output ports (for right, left, upper and lower images), and the image signal can be read
out in high speed from four ports.(QUAD mode) At that time, the right,left,upper and lower quarters of image data are
synthesized to make a full area picture image bringing together at a center boundary of the screen. Then the right, left,
upper and lower output may differ in level, as the four output characteristics are not exactly the same. This equipment has
the automatic correction function to reduce and obscure the level difference at the boundary. The factory default of this
function is OFF. It can also correct the level difference manually deactivating the automatic correction function. Depending
status of camera usage, difference in level or border line may appear on the center boundary. However, it does not arise
from camera failure.
※ALC may not function well depending on image signal state. In that case, adjust GAIN and OFFSET manually
deactivating ALC.
※When ALC(CONTINUOUS) is operating, GAIN correction value obtained by ALC(1 shot) gets disabled.
The target video level is that of reference image obtained in advance (Right and left)
The initial value of reference image video level (right and left levels) is 160 (8bit scale).
(Refer to “Serial communication control” for more detailes.)
1. ALC (CONTINUOUS:always-on)
GAIN correction value is controlled to bring the video level closer to the target level detecting the right and left video
levels. GAIN correction value is controlled every time the image is renewed. GAIN correction value always varies.
OFFSET correction value is not controlled and when ALC (1 shot) is in effect the correction value of that is applied.
This function becomes effective when bit 12 of configuration register is “1”.
2. ALC (1 shot)
GAIN correction value and OFFSET correction value are determined from image signal when correction value
acquisition command (serial communication) is received. These correction values becomes effective when bit 11 of
configuration register is “1”.
・OFFSET correction value acquisition ALC (1 SHOT_O)
CCD is closed using the electronic shutter function when the command is received. After that, the right and left
OFFSET correction values are computed to adjust the image level when CCD is closed to the defined value using
predetermined number of frames of image signal. It is automatically terminated when predetermined number of
image frames are renewed and the value upon termination becomes OFFSET correction value of ALC(1 shot).
・GAIN correction value acquisition ALC (1 SHOT_G)
When the command is received, the right GAIN correction value is computed using predetermined frames of image
signal to minimize the level difference between right and left images. It is automatically terminated when
predetermined number of image frames are renewed and the value upon termination becomes GAIN correction
value of ALC(1 shot).
・ALC (1 SHOT_G) correction value clear
It is to clear GAIN and OFFSET correction values set at ALC(1 SHOT_O,G).

Shutter ,of which the exposure time is less than one frame, is used.
The exposure time can be set as a preset shutter speed at 9 different levels both for
the continuous shutter/asynchronous shutter operations.
Low speed shutter
The shutter, of which the exposure time is two frames or over, is used.
(Only for continuous shutter mode) The exposure time can be set as a preset shutter
speed at 9 different levels.
(Note) This camera allows this setting only for the continuous shutter mode.
Pulse width control
Only in the case of asynchronous shutter setting, the shutter, of which the exposure
time corresponds to the pulse width (during L level) of the external trigger input
(Vinit), is released.
Exposure time can be set as nH (n = 1 or larger integer number) in H (horizontal
synchronous time) unit.
Table 5-4. Other operation mode
Scanning
system
Normal scan
The readout for each frame is conducted by the all pixel readout scanning.
[Terminology] Preset shutter··········This refers to the shutter speed setting other than those specified by the pulse width
control. More specifically, the shutter speed is set by the shutter switch positions
from “1”to “9”for the continuous shutter operation, or the shutter switch positions
from “1” to “9”(PWC (Pulse width control mode)=DISABLED) or from “1”to “8”
(PWC (Pulse width control mode)=ENABLE) for the asynchronous shutter operation.
The shutter speed is defined in the Table 6-1.
[Terminology] Pulse width control·····This is the way of setting and controlling of the shutter speed by the width of the Vinit
signal that is externally input in the asynchronous shutter mode. With this camera,
this is selected by setting PWC to “ENABLED”and the shutter switch position to “9”
in the asynchronous shutter mode.
(!) In conventional camera, the shutter speed type was always pulse width control mode when in asynchronous shutter
mode and when the shutter switch position is “9”. however, the shutter speed of this camera becomes preset fixed
shutter when it is set “PWC=DISABLED”, even if the shutter switch position is “9”in the asynchronous shutter
operation.
[Terminology] High speed shutter·····This means the shutter of which shutter speed is shorter than 1 frame duration (=1
vertical synchronous time). The shutter speed is set as a preset fixed length of the 9
different levels that are determined by the position of the shutter switch (continuous
shutter and asynchronous shutter).
[Terminology] Low speed shutter······This means the shutter of which shutter speed is longer than 1 frame duration. The
shutter speed is set as a preset fixed length of the 9 different levels that are
determined by the position of the shutter switch (continuous shutter).

(5-2) Setting of shutter speed
The shutter speed is determined by assigning “0 - 9” to the shutter switch position or specifying the shutter speed in H

As this camera is not equipped with the substantive shutter setting switch, the shutter speed is specified using the serial
communication command via serial communication software.
The shutter speed setting is mainly decided by setting position “0” to ”9” of (Hypothetical) shutter switch.

Pulse width control / asynchronous (!)
(Note) (H) and (V) in the table represent the horizontal time unit and the vertical time (frame duration) unit respectively.
(Note) ”No shutter” in the table means the continuous shutter mode with exposure time = 1 frame duration.
(Note) The value of the each shutter speed is the factory default value. The shutter speed of each position (excluding
shutter position = 0) is possible to change by the user with serial communication command.
(!) As for this camera, “Pulse width control time/asynchronous” must be set to be “Pulse width control (PWC) =
ENABLED”.
When it is set to be “Pulse width control (PWC) = DISABLED” (default), the selection can be made out of the 9 levels
not only for the continuous shutter operation but also for the asynchronous shutter operation.
(!) “Shutter switch” means the hypothetical shutter switch set on the memory inside the camera via serial communication
command.
(5-3) Level setting
The level setting is mostly divided into the following
two groups:
●Gain setting
This is to set the gain (amplification ratio) of the
preamplifier between the CCD imaging device
inside the camera and A/D converter.
●Offset setting
This is to set the offset of the preamplifier between
the CCD imaging device inside the camera and A/D
converter.
→ Refer to the next section (Section 6) for the
specific setting method.
(Note) As for the offset setting, it is recommended to
use the factory default setting except for a
special case.
(Note) Follow the procedure (gain setting →offset
setting) if fine tuning of the offset value is
required.
[Explanation]
The shutter speed is specified by reading out the value on the electronic shutter table (separately exist on page A to F )
corresponding to the set position of shutter switch.(excluding directly designated value )
The electronic shutter table can all be rewritten with the serial command “E” (shutter table Edit command) except shutter switch ”0”..

(5-4) Gain setting of preamplifier
●Gain variable amplifier and integrated gain
The image signal output from CCD is amplified inside the
camera through the fixed gain amplifier on the anterior
stage and then through the following variable gain amplifier
before being input into theA/D converter.
The left block chart shows this flow.
(Note) The gain value (dB) described here is the one based on
the CCD output (0 dB) as the baseline.
●Correlation between MGC gain setting value and MGC gain
This equipment is controlled by giving the MGC setting
value. The correlation between this setting value and
the MGC gain (integrated gain including the gain of the
variable gain amplifier and that of the fixed gain
amplifier) is shown in the right graph.
(Note) When the CCD element receives excessive light
with a low gain value of the amplifier due to the
restriction of the dynamic range of the CCD light
receiving element, the signals of the nonlinear
area of the CCD element and the preamplifier
are output at the high brightness area.
In this state, unnatural image (Note below) may
appear in the neighborhood of the saturating
signal area of the image due to the
characteristic of the nonlinear area. This
phenomenon, which is associated with the
saturation characteristic of the CCD element, is
not a failure arising from the camera.
To eliminate this phenomenon, reduce the amount of
light by stopping down the lens and newly set a higher
gain value. Then, the output signal from the CCD
element at the saturating area will be appropriately
saturated into a white level for the output.

(Note) The above described unnatural image
represents the following states:
●Black and white look inverted at the saturating area.
●The outline of the saturating area is blurred.
●The saturating area slightly shifts upward or downward.
●The brightness of the saturating area does not reach 1023.
(5-5) Program page setting
The FC series cameras are internally equipped with nonvolatile memories
then various operation mode settings and level settings can be stored in
them. The setting items are stored in the virtual pages (hereinafter referred
to as “program pages”) inside the camera.
This camera has 6 program pages of “A”, “B”, “C”, “D”, “E” and “F” (right
figure).
The camera starts operating according to the various settings stored in the
relevant page when the mode switch is at any one of the positions from “A”
to “F”at the time of power-on.
(!) As this camera is not equipped with the substantial shutter setting switch
on the rear panel, “Mode switch”described here means setting values of
hypothetical mode switch set on the memory inside the camera.
The position of this (hypothetical) mode switch can be set, read and
saved with serial communication command.
(Note) The memory has the configuration area aside from the saving area
of the program pages that is independent from the program pages.
The common setting items (Configuration items) are saved on this area.

6. Various setting via serial communication
This camera is not equipped with the substantial switches. Setting parameters for shutter speed, gain, offset or operational mode
can be manipulated in a manner to directly provide serial communication command to the camera using serial communication
software (such as “FCTool”).
(6-1) Operation setting register
Setting of camera operation is performed by writing numerical values or status of flag onto the register on the memory inside the
camera. It can confirm or change the setting by using serial communication command.
These registers are divided into two main groups, the registers which is in the saving area of each of A to F six program pages
(Program page items) and the registers which is in an common area independent from the program pages (Configuration items).
[Operational mode setting-related registers ]
※EXP_ MAX: The maximum value which is possible to directly designate as a shutter speed. In this camera(FC2600CL),
EXP_ MAX(Maximum value) is “H’023C”(=D’0572) for the high speed shutter(QUAD/DUAL) , “H’0478”(=D’1144) for the high
speed shutter(SINGLE), and “H’0032”for the low speed shutter.
(6-2) How to set Shutter speed
The shutter speed is determined mainly by the set position “0”to ”9”of the (hypothetical) shutter switch.
Refer to Table 5-5 “Setting value of shutter speed”for the shutter speed corresponding to each set position.
●The shutter speed setting by the serial communication command
The shutter speed setting is done by inputting the serial communication commands as this camera is not equipped
with the substantial shutter switch.
The shutter speed setting is divided into the following three categories.

[Explanation] Vsub voltage
Vsub voltage is the bias voltage (substrate voltage) that serves to control the blooming effect (resulting in blur or running image
at a saturating area) that arises from excessive light getting into CCD.
If a high Vsub voltage is set, the blooming effect can be reduced, although an excessively high voltage leads to a narrower
operation range of CCD because it is associated with a decrease in the saturating voltage of the CCD output.
It is appropriately set before shipment because the optimum Vsub voltage varies by CCD.

Transmit as follows
Transmission from host: STX : “S…0064”: ETX
(Note) Settable minimum value of the shutter exposure time is “0001”(=D’1), EXP_MAX (maximum value) is “H’023C”
(=D’0572) in high speed shutter mode(QUAD/DUAL), “H’0478”(=D’1144) in high speed shutter mode(SINGLE) and
“H’0032”in low speed shutter mode.
The normal image cannot be output if the value beyond the above range is set.
Also, the external shutter setting is cancelled when “0000”(=D’0) is designated. (next section)

[Cancellation of external designation in shutter setting]
The shutter switch position set by “S command”or the external designation of the shutter exposure time (above two methods) is
applied ahead of (hypothetical) shutter switch position.
These shutter setting (the external designation of the shutter switch position and the shutter exposure time) is cancelled by
transmitting “0000”with “S”command as the exposure time parameter.
[Example] To restore the current shutter switch setting to the value designated by the (hypothetical) shutter switch.
Transmit as follows
Transmission from host: STX : “S…0000”: ETX
(6-3) How to set Mode switch
The mode switch is also hypothetical switch.
It can designate the program page on camera start-up by setting the mode switch position to any of A to F.
(!) It corresponds to the method setting the mode switch on the rear panel of the conventional camera.
●Command “WMSW”
Function: Command for writing the mode switch set value (Write Mode Switch)
Transmission from host: STX : “WMSW”: set value : ETX
Return by camera: STX : ACK : ETX (transaction completion) or STX : NAK: ETX (transaction rejection)
※The “set value”(one character: “A”to “F”) is written into mode switch.
(Note) Set contents by this command are all lost when the power is turned off as they are not written into EEPROM
(nonvolatile memory) by this command. Execute another command “SMSW”(Save Mode Switch) if it is needed to save
the set contents into EEPROM.
[Example] To set the mode switch to “C”
Transmit as follows
Transmission from host: STX : “WMSW”: “C”:ETX
Right figure shows the example of transmitting the command using
FCTool. The mode switch is set to “C”.
●Command “RMSW”
Function: Command for reading out the mode switch set value (Read Mode Switch)
Transmission from host: STX : “RMSW”: ETX
Return by camera: STX : ACK : “RMSW”: set value : ETX (transaction completion) or STX : NAK : ETX (transaction
rejection)
※The current “set value”(one character: “A”to “F”) of the mode switch is read out.
[Example] To read out the current set value of mode switch
Transmit as follows
Transmission from host: STX: “RMSW”: ETX
Right figure shows the example of transmitting the command using
FCTool. Set value of mode switch “F”is read out.
●Command “SMSW”
Function: Command for saving the mode switch set value (Save Mode Switch)
Transmission from host: STX : “SMSW”: ETX
Return by camera: STX : ACK : set value : ETX (transaction completion) or STX : NAK : ETX (transaction rejection)
※The current “set value”(one character: “A”to “F”) of the mode switch is saved into nonvolatile ROM.
[Explanation]
The set contents of the program page can not be read out by merely changing the program page settings.
The set contents designated in this page are automatically loaded when the set values are saved in nonvolatile ROM and restarted
(application of power or “ARESET”) next time.
The mode switch position is set to “A”as default .The set contents stored in program page Ais automatically loaded at start-up and the
operational mode is determined.

(6-4) How to set Gain and Offset
“G”command is used for Gain setting.
Transmission from host: STX: “G”: MGC set value: (AGC set value): (VRT set value): (VRB set value): OFFSETset value : ETX
Return by camera: STX :ACK : ETX(transaction completion) or STX: NAK : ETX (transaction rejection)
●MGC Gain setting …Setting the fixed gain.
●OFFSET setting …Setting the fixed offset.
[Example] To set the MGC gain to “123”(=H’7B)
Transmit as follows
Transmission from host: STX: “G”: “7B”: “….”ETX
(Note) “….”(four periods)
Right figure shows the example of transmitting the command using
FCTool. The MGC set value is set to “7B”.
●Adjustment of Gain and Offset
The camera has three types of CCD output system; SINGLE(one output port), DUAL(two output ports) and QUAD(four
output ports). Gain and Offset must be set for each output system and they are controlled by four kinds of set values;
MGC set value, MGC(B,C,D) correction value, OFFSET set value and OFFSET(B,C,D) correction value.

・Gain and Offset setting in SINGLE ・Gain and Offset setting in DUAL ・Gain and Offset setting in QUAD
MGC set value and OFFSET set value of the above G command control Gain and Offset of the entire image in SINGLE, of
the left half image in DUAL and of the upper left image in QUAD, and are also the base value for the another part.
For example. The Gain of lower right image in QUAD is controlled by MGC set value + MGCD correction value, and the
Offset is controlled by OFFSET set value + OFFSETD correction value. Therefore, the entire GAIN and OFFSET can be
changed by changing MGC set value and OFFSET set value using G command.
However, when GAIN and OFFSET is changed widely, it may needs to change each correction value.
”WMG”command is used for Gain setting.
Transmission from host: STX : “WMG”: MGC set value: MGCB correction value: MGCC correction value: MGCD correction
value: ETX
Return by camera: STX :ACK : ETX(transaction completion) or STX: NAK : ETX (transaction rejection)
●MGC correction value …It is given in two's complement.
[Example] To set the lower left Gain in QUAD to the value that is one
less than MGC set value.(To set MGCD correction value to
“-1”(=H’FF))
Transmit as follows
Transmission from host: STX: “WMG”: “…”: “FF”: ETX
(Note) “…” (three periods)
“WOF”command is used for Offset setting.
Transmission from host: STX : “WOF”: OFFSET set value: OFFSETB correction value: OFFSETC correction value: OFFSETD
correction value : ETX
Return by camera: STX :ACK : ETX(transaction completion) or STX: NAK : ETX (transaction rejection)
●MGC correction value …It is given in two's complement.
[Example] To set the left half Offset in DUAL to the value that is one greater than OFFSET set value.(To set OFFSETB
correction value to “+1”(=H’01))
Transmit as follows
Transmission from host: STX: “WOF”: “.”: “01”: “..”: ETX

(6-5) Internal flag register and configuration register
There are RAM areas inside the camera consisting of flag register (FR) (2 bytes) and configuration register (CR) (4 bytes)
which defines the operational mode of the camera.
It is possible to recognize the current operational status with these register contents and to change multiple operational
modes at a time by rewriting the register contents using serial communication command.
The functions of each flag register and configuration register are described below.
●Flag register (FR) and configuration register (CR)
The contents of the internal EEPROM (nonvolatile ROM) are retrieved at the time of startup and copied onto FR (two bytes,
16bit) and CR (four bytes, 32bit) which are the storage area on RAM. The camera decides the current operational mode in
accordance with the contents of FR and CR.
The one each of the contents of FR is saved on each program page (Ato F) and that contents is copied onto the flag
register to decide the operational status by auto-loading on start-up or manual loading of program page. In contrast, the
contents of CR is saved on a single storage area on EEPROM and they are read out independently of program page to
decide the operational mode.
●Contents of (FR) and (CR )
When the OSD menu is turned on, the contents of each register are displayed on the menu in twelve digits like
“MF=0000.0000.0000”representing the current status of the registers.
Each numerical value is displayed in hexadecimal system. And each part represents the set contents of configuration
register(CR(H)), configuration register(CR(L))and flag register(FR), from left.

(Note) The contents of FR are all “0”by default (Factory default).
(Example)If “MF=0001.0008.0003” is displayed on the menu screen, the camera is in the following state (converting the
numbers to ones in binary system):
CR_H=B’0000000000000001, CR_L=B’0000000000001000 and FR=B’0000000000000011
……… CR_H(0)=CR_L(3)=FR(1)=FR(0)=1, All other bits = 0
(Where CR(n) and FR(m) represent the nth bit of CR and mth bit of FR respectively)
Based on 1/0 state of these bits and the information in the above table, the user can know that the camera is in
the state of “with Sorting”,”8 bit output”,“ASYNC” and “Enabled pulse width control”.
(Note) Any of set items of FR are only stored on the nonvolatile memory by saving those to any of program page “A”to “F”
using “WA”to “WF”command (Write into page memory A to F) before turning the power off.
Also set items of CR are stored on the nonvolatile memory inside the camera by executing “SMC”command (Save
Mode Configuration) after changing.
Note that the changes in either setting are not saved when turning the power off without saving (onto nonvolatile
memory) and the set contents return to those before setting change at the next power-on.
(Note) CR is applied independently of the current program page, as it is one of the configuration items.
[Terminology] Configuration item ... The common configuration item that is independent of the program page.
The configuration items contain hypothetical mode switch, hypothetical shutter switch
and VSUB voltage set value in addition to CR.
●Setting of configuration register (CR ) by serial communication command
Setting ,reading and saving of CR in this camera are all executed using serial communication command.
●Command “WMCH”, “WMCL”
Function: Command for writing on the configuration register (Write Mode Configuration)
Transmission from host: STX : “WMC”: “H”or “L”: set value : ETX
Return by camera: STX : ACK : ETX (transaction completion) or STX : NAK : ETX (transaction rejection)
※“H”or “L”represents CR_H or CR_L respectively.
※“set value”(four characters in hexadecimal) is written on CR .
(Note) This command does not execute the writing in EEPROM, and the setting by this command is lost when the power
is turned off. To save the setting value in EEPROM, use another command, “SMC”(Save Mode Configuration).
[Example] To set “0400”(=H’0400) to CR_L.
Transmit as follows
Transmission from host: STX: “WMCL”: “0400”: ETX
Right figure shows the example of transmitting the command using
FCTool. The CR_L is set to “0400”.
