The video input selection and signal parameter settings for the TVB-

that permits remote control of the unit from a PC via RS-232.
Use a straight thru M/F DB9 serial cable to connect the unit to the PC.
Only the TX, RX and GND pins are implemented in the connector. The
RS232 port operates at 9600 baud, no parity and 1 stop bit. Control
codes are 3 bytes long. In the table shown below, the 1
