JAI CV-L105 User Manual

The binning function, pixel rate and RS-232C function can be controlled by TTL inputs on the 
68pin Hirose interface connector and with jumper settings. 
Below table describe the possible states of these inputs. Please refer to fig. 7. for principle.

There are 5 solder jumpers on the main board (PK8234B), which are accessible for the user. 
On the board (PK8235B) 7 potentiometers are found. The top one marked A/D is for factory 
adjustment. Do not touch it. 
The red, green and blue gain and offset potentiometers is factory adjusted to white color 

balance at 3100K. It is used in factory setting configuration. As the green gain and offset is 
reference, do not touch it.
