Monitor connections

Connect the unit to the monitors using 75-ohm video coaxial cables with BNC connectors. The unit provides a 1Vpp CVBS signal.

If the monitor has a loop-through connection and you are not using the loop- through output, then select the 75-ohm impedance setting on the monitor. If the monitor's loop-through output is connected to an additional device, the device's termination is set to 75 ohms and the monitor's termination is set to high impedance. (Note that this is not necessary on devices with automatic termination.)
