Warning:
This equipment generates and uses radio frequency energy and if
not installed and used properly, I.e., in strict accordance with the
instruction manual, may cause harmful interference to radio
communications. It has been tested and found to comply with the
limits for a Class A computing device pursuant to Subpart J of Part
15 of FCCRules, which are designed to provide reasonable
protection against such interference when operated in a commercial
environment.
For U.S.A.
Warning:
This digital apparatus does not exceed the Class A limits for radio
noise emissions from digital apparatus set out in the Radio
Interference Regulations of the Canadian Department of
Communications.
For Canada

Safety Precautions
Product Precautions
Handle the camera with care. Do not abuse the camera. Avoid striking or shaking it. Improper handling
or storage could damage the camera.
Do not pull or damage the camera cable.
During camera use, do not wrap he unit in any material. This will cause the internal temperature of the
unit to increase.
Do not expose the camera to moisture, or do not try to operate it in wet areas.
Do not operate the camera beyond its temperature, humidity and power source ratings.
While the camera is not being used, keep the lens or lens cap on the camera to prevent dust or
contamination from getting in the CCD or filter area and scratching or damaging this area.
Do not keep the camera under the following conditions:
In wet, moist, and high humidity areas
Under hot direct sunlight
In high temperature areas
Near an object that releases a strong magnetic or electric field
Areas with strong vibrations
Use a soft cloth to clean the camera. Use pressured air spray to clean the surface of the glass. Do NOT
scratch the surface of the glass.

IV. Communication Protocol Specifications
This camera has a communication function that enables external devices, such as the PC, to control the camera functions and
parameters. Use the “CLCtrl” communication software (version 9.0 or later) to communicate, or follow the communication protocol
described below to communicate with the camera.
Note: A communication problem may occur under the following conditions:
When the external sync frequency is out of the specification (more than 1% off from the specified normal frequency)
When external sync is unstable.
Approximately for one second after changing the sync mode.
Approximately for one second after switching the frame rate.

Descriptions
SOF
Start of the frame. The set (or receive) value is always “02H”
Device Code
This indicates the destination of the communication
The device code for the camera is “000000”. Other codes are the peripheral devices.
Read / Write
This specifies “Read” or “Write” to command numbers. Set 0 for “Read” and 1 for “Write”.
Page Selection
This specifies page selection (access selection) to registers and EEPROM of command.
Set 0 to access the command register of the camera.
Read command: To read the current data from the command register.
Write command: To set the data into the command register. The data in the EEPROM is not replaced.
Set 1 to access the EEPROM of the camera
Read command: To read the data from the EEPROM
Write command: To save the data into the EEPROM as default data
Notes:
1. The camera operates with the data in the EEPROM when the camera is powered on.
2. The camera returns the receiving code “01H” to the PC after save the data into the EEPROM. The camera rejects any commands
during the data saved (approximately 5 mseconds / byte) and returns the receiving code “07H” (busy) to the PC.
Command Code
This indicates the command. Refer to the following page for the details.
Data Length
This indicates the data length (Unit is byte).
Sending data: Set to 0 when sending the read command. The data length is dependent on each write command when sending the write
command.
Receiving data: The data length is dependent on each write command after sending the read command.
Receive “00H” after sending the write command.
Receive “00H” when an error has occurred.
Data
This indicates write data or read data according to the command type.
EOF
End of the frame. The set (or receive) value is always “03H”
Receiving Code
This indicates result of the sending command:
01H: Receiving OK (ACK)
10H: Receiving problem (NAC)
07H: The camera is in process (Busy)
11H: Communication problem

SVR[15…8]
[The exposure time (H) of the electronic shutter]
Initial data: SVR[15…0] = 0, data range: 0 to 313
This and SHR[15…0] set the preset shutter speed (or CCD exposure time) for the electronic shutter.
The preset shutter speed is defined by the following formula:
Preset Shutter Speed = SVR[15…0] x (1H cycle time) + SHR[15…0] x (1CLK cycle time)
Notes:
1. The data in 20H through 23H reflects to the present shutter speed.
2. The camera works with the shutter off (maximum shutter speed) when both SVR[] and SHR[] are set to 0.
3. The camera works with the minimum shutter speed when this value is set to 0 and SHR[] is set between 1
and 142.
4. The value replaces by 313 automatically when this value is set to greater than 313.

The preset shutter speed is defined by the following formula:
Preset Shutter Speed = SVR[15…0] x (1H cycle time) + SHR[15…0] x (1CLK cycle time)
Notes:
1. The data in 20H through 23H reflects to the preset shutter speed.
2. The camera works with the shutter off (maximum shutter speed) when both SVR[] and SHR[] are set at 0.
3. The camera works with the minimum shutter speed when this value is set between 1 and 142 and SHR[] is
set to 0.
4. The value replaces by 907 automatically when this value is set to greater than 907.
30H:
PGA[7…0]
[The CDS gain] Initial data; PGA[7…0] = , data range: 0 to 255
This sets the CDS gain, which is the programmable gain.
CDS gain is defined by the following formula:
CDS Gain = 3.64 + 0.132 x (PGA[7…0] + GOFS[7…0]) (Unit is dB)
The analog gain of CCD output is defined by the DCS gain as shown below:
Analog gain = pre-amp (6 dB) + CDS gain (Unit is dB)
31H:
DGB[7…0]
[The digital gain] Initial data: DGB[7…0] = The value in the address 0EH, data range: 0 to 255.
This sets the digital gain.
The video output level is defined by the following formula:
Video output level = (Input video level –CLAMP[7…0] x (1 + (DGB[7…0] / 128) + CLAMP [7…0])
Notes:
1. GOFS[7…0]: The gain offset, which is the value in the address 32H.
2. CLAMP[7…0]: The clamp level, which is the value in the address 38H.
32H:
GOFS[7…0]
[The gain offset] Initial data: GOFS[7…0] = The value in the address 0FH, data range: 0 to 63
This sets the gain offset.
38H:
CLAMP[7…0]
[The clamp level] Initial data: CLAMP[7…0] = The value in the address 0FH, data range: 0 to 63.
This sets the gain offset.
