On the rear of each ScreenPRO-II chassis, one recessed Termination Switch is provided
for genlock termination (adjacent to the Genlock Loop connector).
• Terminated — when the switch is pushed in, the connection is terminated (75
Ohms).
• Un-terminated — when the switch is out, the connection is un-terminated.
If a particular ScreenPRO-II chassis is the last device in a reference video chain, ensure
that the Termination Switch is pushed in. If a particular ScreenPRO-II chassis is in the
middle of a reference chain, ensure that the Termination Switch is out.
