CV-L105

7.2. Configuration via I/F connector and jumpers

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.

O = jumper open
S = jumper short

H = input high. ( open. 5V by the internal 4.7 kΩ pull-up resistor) L = input low. (closed to GND)

7.3. Potentiometers and jumpers placing

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.
