OUR PART # 11-113-104
The input for these products consists of a 75 Ohm BNC or RCA connector. A video signal with excessive DC component (or offset) such as those generated by many computer video boards will cause the VAC Brick to malfunction. The 1Vpp video signal needs to be within -1V to +1V. Ideally, the video signal's blanking level should be clamped to 0 volts, although an AC coupled signal is also acceptable.
The VAC Brick has four video outputs consisting of 75 Ohm BNC or RCA connectors. Each output has a series impedance of 75 Ohms. Unused outputs do not need to be terminated for proper operation of the Brick. Using terminators on unused outputs provides additional protection for the Brick from ESD (static electricity) events.
