If a long line drive setting has been selected then a series of resistors and capacitors are put in the path of the video signal. These components have the affect of attenuating the high frequency components of the video signal thus compensating for long cable lengths. After this the video signal is buffered to allow it to have the current to go up a long cable and to protect the circuits incase a high voltage spike comes down the cable. 14-366-6011 Protection Board Circuit Description The 14-366-6011protection board has 3 functions. First off all it provides over voltage protection for all inputs to the camera. Transorbs protect from over-voltage, both spikes and steady state voltages. Fuses protect against fault conditions where too much current is drawn. EMC filters are added to suppress EMC emissions. The 2 nd purpose of the board is to convert the 16V- 24V supply voltage to a lower voltage that supplies the rest of the circuitry. This includes 12V to the camera module and some electronic components, 5V for powering most of the IC’s, Isolated 5V to isolate some input circuitry as to prevent noise on the video line and 6.2V as a reference voltage for tri-state operation. The final purpose of the board is to send the input signals to the correct place on the interface board. It separates tri-sate, bi-polar, RS485 and USB signals and sends them to the correct processing IC on the interface board.

A PIC microcontroller is the main controller. In Bi-polar or tri-state mode it reads in the signals via A/D converts and tells the camera module to zoom or focus. RS485 signals are isolated, converted to TTL logic levels and read into the PIC via its serial port. The command is read in and the action is sent to the camera module or processed internally. USB signals are read in by an IC, which converts them to serial data and read into the same serial port on the PIC as the RS485 signals. The board also contains a humidity sensor to monitor temperature and humidity levels and an IR receiver to deal with signals coming in from the IR remote.
