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 12pins circular 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 camera power is OFF, it becomes high-impedance mode).
・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 12pins circular 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.
5. Serial Communication
5.1 Serial Communication Settings
Camera supports RS-232C control via 12pins circular connector of camera rear.
(1) Please refer to the chart below for serial communication settings.
Baud rate
9,600bps
Data
8bit
Stop bit

Parity
None
XON/XOFF
No Control
(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 the 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 the 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.

Defective Pixel Correction
Function
Address
Value
Description
Detection of
defective pixel
200
The 1st Parameter:
Threshold level : 0 ~ 4095
This is to detect defective pixels
(white defect) and register them as
user register data. Defective pixels
are output value, which exceeds the
threshold level.
Execute this command with light
shielded and set appropriate gain and
shutter values.
The 2nd Parameter: Registration mode.
0: New registration
1: Additional registration
Registration of
defective pixel
201
The 1st Parameter:
X coordinate: (0 ~ 3839)
This is to register defective pixels as
user register data by specifying their
coordinates.
The 2nd Parameter:
Y coordinate: (0 ~ 2159)
Deletion of
defective pixel
202
The 1st Parameter:
X coordinate: (0 ~ 3839)
This is to delete defective pixels from
user register data by specifying their
coordinates. (Dedicated to SU)
The 2nd Parameter:
Y coordinate: (0 ~ 2159)
Entire deletion of
defective pixel
correction data
203
1: Entire deletion
This is to delete all user register
Data. (Dedicated to SU)
Indication of
defective pixel
correction data
204
1: Indicate the coordinates and their attributes
of all defective pixels.
2: Indicate the coordinates and their attributes
of user register data.
3: Indicate the total number of all registered
defective pixels per region.
4: Indicate the number of user register
defective pixels per region.
This is to indicate information on the
registered defective pixel correction
data. (Dedicated to GU)
Note:
When user specifies “new registration” with defective pixel detection command, the command deletes only user register
data by defective pixel detection. The command does not delete data registered by defective pixel registration command.
The command classifies registered defective pixels into four types. Attribute [W] and [B] are for data registered at
factory, attribute [U] is data registered by user with defective pixels detection command, and attribute [P] is data
registered by user with defective pixels registration command.
[GU 200] command shows the number of pixels classified under [U] attribute, and [GU 201] command shows the number
of pixels classified under [P] attribute.
User can change only user register data, and cannot remove the factory setting data.
User cannot register the pixels already been registered as factory data.
