Camera Command and Control Camera configuration is set through the serial interface. Please refer to “Serial Communication” on page 11 for the detailed protocol of the serial line. Note:
1. e2v commends to use E = 1 because of the limited EEPROM write cycles refer on page 12. 2. Camera gain (dB) = G x 0.047. A and B gain value are set in manufacturing but can be adjust if necessary. 3. Commands “H=2” and “H=4” will give 10 and 15 MHz data rate which are not compatible with Camera Link standard. Please don’t use it. 4. The pinout corresponding to this option is fully compatible with the Camera Link standard. Table 7-1.
