1. Handling Precautions
1.1. Camera Handling Precautions
□Please make sure to take appropriate measures for heat dissipation. Operating camera module without taking
appropriate heat dissipation may cause damages or malfunction.
□Do not use or store camera module in dusty or humid places.
□Do not apply excessive force, vibration, or static electricity that could damage camera. Handle camera module
with care.
□Do not shoot direct images that are extremely bright (e.g., light source, sun, etc.). When extremely strong
light source is shot, smear or blooming may occur. Put the front cap on when camera is not in use.
□Follow the instructions in Chapter 3.2., “External Connector” for connecting camera module. Improper
connection may cause damages not only to camera module but also to the connected devices.
□Confirm mutual ground potential carefully before connecting camera module to monitors or computers.
Any AC leak from the connected devices may cause damages or destroy camera module.
□Do not apply excessive voltage. (Use only the specified voltage.) Unstable or improper power supply voltage
may cause damages or malfunction of camera module.
□Our warranty does not apply to damages or defects caused by irregular and/or abnormal use of the product.
□Please make sure to use fully dust-proof chassis/casing to avoid dust reaching the surface of the image sensor.
Assemble camera module to your products under clean environment such as clean room.
Our warranty does not apply to damages or defects caused by neglecting the instructions and precautions explained
in this manual.
1.2. Restrictions on Applications
□The camera module must not be used for any nuclear equipment or aerospace equipment with which
mechanical failure or malfunction could result in serious bodily injury or loss of human life.
□The camera module must not be used under conditions or environments other than those specified in this
manual.
1.3. Disclaimers (Exception Clause)
CIS should not be liable for any damages or losses if;
・damages or losses are caused by earthquake, lightning strike, fire, flood, or other acts of God.
・damages or losses are caused by deliberate or accidental misuse by user, or failure to observe information and
instructions explained in this manual.
・damages or losses are caused by repair or modification conducted by user or any unauthorized party.

4. Camera Functions
4.1. GenLock
Gen Lock function is available by inputting Analog External Sync signal (Black burst or 3-values SYNC) into the
EXT SYNC IN terminal of the control connector. Corresponding external sync signals vary depending on camera
output format. Please refer to the chart below for details.

・Input Black Burst signals for NTSC/PAL signals.
・Input 3-values SYNC signals for other than NTSC/PAL signals.
・Terminate EXT SYNC IN with 75Ω.
・When an external signal specified above is input, the camera will automatically be in external sync mode.
・When there is no external signal input, the camera will operate in internal sync mode.
・Disturbance images occur immediately after inputting external signal. However, this is normal.
・Disturbance images may occur or there will be no image when inputting signals other than those specified in the
above chart to the EXT SYNC IN terminal.
・Maximum ±10 pixels difference between video signals and external sync signals occur immediately after initializing
camera or changing output format. If this difference (error) is not acceptable, automatically lock with external sync
and match the timing with user adjustment commands.
4.2. LTC (Longitudinal Time Code)
Supports Time Code insertion to 3G-SDI signals.
Input LTC signals (time code) to the LTC IN terminal of control connector to insert external time code. When there is
no signal-input to the LTC IN terminal, user can insert internal time code. Internal time code starts with 00:00:00.00
when power is ON, and when signals are input to the LTC IN terminal, time code switches to external time code.
Under this condition, if no signal is input to the LTC IN terminal, internal time code starts.
Signal format:
SMPTE Time code
Signal level:
0.5~2[Vp-p]

4.3. Defective Pixel Correction
In addition to the correction of defective pixel data registered upon shipment, we provide a method to update the
defective pixel data. Please refer to Section 5.2, Command List for details.
4.3.1 Defective Pixels Type
There are two types of defective pixel data.
Defective data registered at factory
Data registered upon shipment from our factory. These data cannot be over-written.
Defective data registered by user
Data registered by user.
There are four kinds of position data for defective pixels; No Flip, H Flip only, V Flip only, and both H/V Flip. According
to the combination of H Flip and V Flip settings, the type of position data changes automatically.
4.3.2 Details on Defective Pixel Data
Defective pixel data are stored and controlled per four vertically divided regions. User can register up to 64 points per
region, which makes it a total of 256 points as user register data. There are overlaps of 32 pixels (width) between the
regions. The command register the defective pixel coordinates in the overlapping area to both regions. Please refer
to the below for the definition of regions.
The upper left is the origin of coordinate system. Definition of each region is
Reed Area 0 : (0,0) - (975, 2159)
Reed Area 1 : (944,0) - (1935 ,2159)
Reed Area 2 : (1904,0) - (2895, 2159)
Reed Area 3 : (2864,0) - (3839, 2159)
For example, if the defective pixel is at (943, 0), the data is registered only to region 0.
However, if the defective pixel is at (944, 0), the data is registered to both region 0 and 1
Area 0
Area 1
Area 2
Area 3

4.3.3 Notes for Defective Pixel Correction
To save the data registered or deleted with defective pixel correction command (SU 200~203), execute SAVE
command (SU705).
Init command (SU 700) does not restore defective pixel correction data. Use SU 203 to delete all data.
Defective pixel correction data is not subject to Camera Setting Store/Load command (SU 100/101).
Factory data and user-register data cannot be the same. Therefore, if user detects the same defective points,
this function ignores those points.
If user specifies the same coordinates as factory setting data, error will occur.
Please note that the detected results may not always be the same due to temperature, noise, and other
conditions.
Neglecting these instructions may cause not only incorrect pixel defect correction, but also failure of acquiring
proper images.

(2) Control code
・Text-based communication executes camera control. Only ASCII 0x20~0x7E, 0x0A (LF=¥n), and 0x0D
(CR=¥r) must be used. Please do not use other than these codes.
・A control code consists of command, parameter, and CR (0Dh). By sending command, parameter, and
linefeed code from host to camera, user can change camera settings and acquire camera-setting parameters.
Either CR or LF can be a linefeed code.
・There are two types of commands. One is SU command to send settings and instructions to camera (“S” for
“Set”), and the other is GU command (“G” for “Get”) to obtain information from the camera.

(3) How to input commands
・“>”must be output from the camera as a prompt.
・Commands are not case-sensitive.
・Separate between a command and a parameter by single space (0x20).
・From the head of the input character to linefeed code (CR) is defined as a single serial command.
・Parameters start with 0x are regarded as hexadecimal, parameters start with 0b are regarded as binary, and
others are regarded as decimal.
・Commands analyze parameters from the head to identifiable letters.
・Please refer to “Section 5.2. Command List”for details on address and data.
・Do not input values and letters other than those explained in the above and those mentioned in “Section 5.2.
Command List”.
・Camera receives the returned command from Host, and echo the command back. At this time, camera
converts the linefeed code (CR) to CR LF and echo the code back.
