5.4. Input output Circuits
In the following schematic diagrams the input and output circuits for video and timing signals
are shown. For alternative connections refer to “7. Configuring the Camera”. Jumper settings
are shown as for factory default.
RGB video output
The video output signal is a RGB video signal.
The signal level is 0.7Vpp from 75Ω. The video
output is DC coupled.
Composite sync. is selectable on the green
video signal via software or the internal switch
302-3. The sync. signal level is 0.3Vpp.
Iris video output
A video signal for lens iris control is found on
pin 4. 12-pin connector. The signal is with
composite sync. It is ac coupled from a 75Ω
source. It can only be used for iris control in
normal continuous mode.
Fig. 6. Video outputs
Trigger input
The trigger input is AC coupled. To allow a
long wide pulse width, the input circuit is a
flip-flop, which is toggled by the negative and
positive differentiated spikes cause buy the
falling and rising edge. The input signal level
is 4V ±2V. The trigger input impedance is 1.2
kΩor 75Ωselectable via the internal switch
S301-3.
Fig. 7. Trigger input
HD and VD input
The HD and VD input circuit can be 75Ω
terminated via the internal switch S301-1 and
S301-2.
The input signal level is 4V ±2V.
Fig. 8. HD and VD inputs
HD, VD, PCLK, WEN and EEN output
The output circuits for these signals are 75Ω
complementary emitter followers. The single
circuit delivers a TTL signal. The output level
≥4 V from 75Ω(no termination).

6. Functions and Operations
6.1. Basic operation modes
Apart from the standard continuous operation mode, the CV-M77 features four external
triggering modes and a long time exposure mode. In all modes the camera can be synchronized
to an external sync. The shutter time can be selected from 12 fixed steps, or from 788 steps
with 1H resolution. In triggered mode it can also be controlled by the trigger pulse width.
The frame delayed readout can operate in either edge pre-selected trigger, or pulse width
controlled shutter mode.
Switches can set most modes and functions locally. All modes and functions can be remote
controlled by RS-232C control.
Alternative connections for input and output signals can be done by internal jumpers.
For details: refer to “7. Configuring the Camera”.
6.1.1. High frame rate.
From revision C, the CV-M77 camera has a new readout mode. It is the high frame rate mode.
Here only every third line is read out. The 2 lines between are dumped. In this way the Bayer
RGB mosaic pattern is unchanged. The DSP interpolation algorithm for RGB color output can still
be used.
The figures below shows the CCD sensor in normal mode and high frame rate mode. In high
frame rate, the vertical ccd register is clocked with 3 times higher rate. But only the signals
from every third line is transferred to the horizontal ccd register for read out. Signals from the
lines between are dumped.
The horizontal resolution is unchanged, but the vertical resolution is reduced to 1/3.
The advantages are:
Frame rate 3 times higher
The image is sampled from the whole sensor area
Horizontal resolution unchanged

6.2. Input/Output of HD/VD Signal
6.2.1. Input of External HD/VD signals
This setting is factory pre-set. The video output is synchronized with external HD/VD signals if
applied. If no ext. HD signal is input, the camera will switch to the internal X-tal controlled HD
sync. If no ext. VD is connected, the camera will continue with its internal VD.
For details: refer to “7. Configuring the Camera”.
To use this mode:
Set function: SW 303.1 and 303.2 to ON for external HD/VD input. Factory default.
SW 301.1 and 301.2 to OFF for TTL level for HD/VD. Factory defaults

6.4. Trigger modes
The CV-M77 camera features 4 external triggering modes:
1 Edge Pre-Select. (EPS). Asynchronous reset and exposure start by an ext. trigger pulse.
2 Pulse Width Control. (PWC). Exposure control by the low period of the ext. trigger pulse.
3 Readout Delay EPS. Triggered EPS exposure. Readout controlled by external VD signal.
4 Readout Delayed PWC. Triggered PWC exposure. Readout controlled by external VD signal.
These external triggering modes operate with H non-reset. In H non-reset, the exposure will be
synchronized to the internal HD, and the exposure will start at the first HD after the negative
going edge of the trigger. Refer to fig. 13. The exposure stops 0.5 H after the last HD pulse.
To avoid the <1H exposure jitter caused by this delay, it is recommended to synchronize the
external trigger to HD as shown in fig. 14.
The trigger input can be TTL level or 75 ohm terminated by setting the specific S301 switch on
the PK 8308 board to OFF or ON (see switch settings). When 75 ohm terminated the signal input
level is 4.0 Vp-p ±2.0V.
Mode setting and all other settings can be done via RS 232C control if rear switch SW1-10 is ON.
Mode setting and some other settings can be done by switch if rear switch SW1-10 is OFF.
For details: refer to “7. Configuring the Camera”.
Important notes on using this mode
Number of effective pixels per line in trigger modes are 1016 (h).

6.4.1. Edge Pre-select Trigger
This trigger mode operates in H non-reset mode. In H non-reset mode the exposure will start at
the first internal HD after the trigger. The trigger input should be longer than or equal to 2 HD
(102 µsec.). The external trigger pulse initiates the capture, and the exposure time
(accumulation time) is governed by the fixed shutter speed set up by the rear panel DIP-switches
or via RS-232C control. The EEN pulse indicates the actual exposure time. The resulting video
signal will start to be read out after the selected shutter time. The WEN pulse indicates the start
of valid video signal. Refer to timing charts for details. A new trigger pulse must not be applied
before the video read out has finished. If the camera is synchronized to an external HD signal,
there are some requirements to the phase between the ext. HD and the Ext. trigger. The falling
edge of the trigger should be less than 8 µsec before the falling edge of the ext. HD and less
than 2 µsec after the falling edge of the ext. HD (see fig. 14.). Otherwise the jitter will be too
high.
Mode setting and all other settings can be done via RS 232C control if rear switch SW1-10 is ON.
Mode setting and some other settings can be done by switch if rear switch SW1-10 is OFF.
For details: refer to “7. Configuring the Camera”.

Input: Ext. trigger in on pin 5 on 6-pin con. (Or 11 on 12 pin). 4.0 Vp-p ±2.0V.
Ext. HD in on pin 6 on 12-pin connector. 4.0 Vp-p ±2.0V. (If used).
Important notes on using this mode
• The start of exposure will start synchronized to the internal H signal. The start may be
shifted max 1H. To avoid this shift (1H jitter), synchronize the camera to an external HD
and make sure that the trigger pulse aligns to the HD as shown in fig. 14.
• The trigger pulse width should be >2H to <2000H.
• A new trigger must not be applied before WEN is high.

6.4.2. Pulse Width Control Trigger
This trigger mode where the length of the trigger pulse determines the exposure time operates
in H non-reset mode. In H non-reset mode the trigger pulse and the HD signal are synchronized.
The exposure will start at the first HD pulse after the falling edge of the external trigger signal.
The exposure ends 0.5 H after the HD following the rising edge of the external trigger signal.
The trigger pulse must be longer than >1H (51µsec) and shorter than 2000 H. To avoid jitter the
camera should be synchronized to an external HD. There are some requirements to the phase
between the ext. HD and the Ext. trigger. The falling edge of the trigger should appear in the
interval less than 8 µsec before the falling edge of the ext. HD and less than 2 µsec after the
falling edge of the ext. HD and the rising edge off the trigger should be fall in the interval 8 µsec
before the rising edge of the ext. HD and 2 µsec after rising edge of the ext. HD. (See figure
14.).
The EEN pulse indicates the actual exposure time.
The resulting video signal will start to be read out after the rising edge of the external trigger
signal. The WEN pulse indicates the start of valid video signal. Refer to timing charts for details.
A new trigger pulse must not be applied before the video read out has finished.
Mode setting and all other settings can be done via RS 232C control if rear switch SW1-10 is ON.
Mode setting and some other settings can be done by switch if rear switch SW1-10 is OFF.
For details: refer to “7. Configuring the Camera”.

Input: Ext. trigger in on pin 5 on 6-pin con. (Or 11 on 12 pin). 4.0 Vp-p ±2.0V.
Ext. HD in on pin 6 on 12-pin connector. 4.0 Vp-p ±2.0V. (If used).
Important notes on using this mode
• The start of exposure will start synchronized to the internal H signal. The start may be
shifted max 1H. To avoid this shift (1H jitter), synchronize the camera to an external HD
and make sure that the trigger pulse aligns to the HD as shown in fig. 14.
• The trigger pulse width should be >1H to <2000H.
• A new trigger must not be applied before WEN is high.

6.4.3. Frame Delay Readout EPS
This trigger mode operates in H non-reset mode. In H non-reset mode the exposure will start at
the first internal HD after the trigger. The trigger input should be longer than or equal to 2 HD
(102 µsec.). The external trigger pulse initiates the capture, and the exposure time
(accumulation time) is governed by the fixed shutter speed set up by the rear panel DIP-switches
or via RS-232C control. The EEN pulse indicates the actual exposure time.
The resulting video signal will first start to be read out after the input of an external VD signal.
The readout delay should not be to long due to visible dark current noise generated in the CCD
sensor. The WEN pulse indicates the start of valid video signal. Refer to timing charts for details.
A new trigger pulse must not be applied before the video read out has finished.
If the camera is synchronized to an external HD signal, there are some requirements to the
phase between the ext. HD and the Ext. trigger. The falling edge of the trigger should be less
than 8 µsec before the falling edge of the ext. HD and less than 2 µsec after the falling edge of
the ext. HD (see fig. 14.). Otherwise the jitter will be too high.
Mode setting and all other settings can be done via RS 232C control if rear switch SW1-10 is ON.

Important notes on using this mode
• The start of exposure will start synchronized to the internal H signal. The start may be
shifted max 1H. To avoid this shift (1H jitter), synchronize the camera to an external HD
and make sure that the trigger pulse aligns to the HD as shown in fig. 14.
• The trigger pulse width should be >2H to <2000H.
• External sync system should follow the camera scanning system.
• A new trigger must not be applied before WEN is high.

6.4.4. Frame Delay Readout PWC
This trigger mode operates in H non-reset mode. In H non-reset mode the trigger and HD is
synchronized. The exposure will start at the first HD pulse after the falling edge of the external
trigger signal. The exposure ends 0.5 H after the HD following the rising edge of the external
trigger signal. The trigger pulse must be longer than >1H. To avoid jitter, the camera should be
synchronized to an external HD. There are some requirements to the phase between the ext. HD
and the Ext. trigger. The falling and rising edge off the trigger should be within 8 µsec. before
the falling and rising edge of the ext. HD pulse and not later than 2µsec after the falling and
rising edge of the HD pulse (see fig. 14.). The EEN pulse indicates the actual exposure time.
The resulting video signal will first start to be read out after the input of an external VD signal.
The readout delay should not be to long due to visible dark current noise generated in the CCD
sensor. The WEN pulse indicates the start of valid video signal. Refer to timing charts for details.
A new trigger pulse must not be applied before the video read out has finished.
Mode setting and all other settings can be done via RS 232C control if rear switch SW1-10 is ON.
Mode setting and some other settings can be done by switch if rear switch SW1-10 is OFF.

6.4.5. Long Time Exposure
The exposure time is the interval between 2 ext. VD pulses sent to the VD input of the camera.
The exposure starts after input of the first ext. VD pulse, and ends after the next input of the
ext. VD pulse, which again starts a new exposure.
The long time exposure is a continuous process where each external VD pulse will synchronize
the camera, stop on exposure, start a new exposure and read out the previous accumulated
signal. The exposure can be selected in intervals of complete vertical timing periods (=792H)
This long time exposure mode operates in H non-reset mode. In H non-reset mode the external
VD signal and the internal HD signal are synchronized. The exposure will start at the first HD
pulse after the falling edge of the external trigger signal. See figure 14. for the phase
relationship between ext. HD and ext. VD pulses.
Mode setting and all other settings can be done via RS 232C control if rear switch SW1-10 is ON.
This mode can not be set by switch!
For details: refer to “7. Configuring the Camera”.

SW301
The SW301 switches (1-3) in “ON” position activates
75Ωtermination of ext. HD and ext. VD signals and it
activates 75Ωtermination of an ext. trigger signal.
The factory setting is “OFF” enabling TTL signal
termination for all three signals.
Fig. 22. Switch 301 HD, VD and trigger termination
SW302
The SW302 switch has the following functions: The switches (1-2) determines the color
temperature, the switch (3) activates Composite sync. on the green video signal and the switch
(4) outputs the WEN signal at the DSUB connector.
The white balance is dependent on the color temperature of the light.
The available settings are shown in the below table.
Fig. 23. Switch 302. White balance, sync on G and WEN
The S302-3 switch adds in “ON” position the composite sync. signal to the green video signal.
The factory setting is “OFF” leaving the green RGB signal without sync. signals.
The S302-4 switch outputs in “ON” position the WEN signal via pin 7 of the 9-pin DSUB
connector. The factory setting is “OFF”. In the “OFF” position the camera outputs the
composite sync. signal via pin 7 of the 9-pin DSUB connector.
SW303
The SW303 switch switches between output of internal HD/VD
signals and input of external HD/VD signals. The factory setting
is input of external HD/VD signals (SW303-1 and SW303-2 in
“ON” position). The “ON” position is towards switch SW301.
