ScreenPRO-II units are shipped from the factory with the Termination
Switch in the "terminated" (75 Ohms) position. If ScreenPRO-II is the
last device in a reference chain, no adjustment to the switch is required.

If you are looping reference video to another chassis in your system, set
the switch to the " high impedance " (Hi-Z) setting.
PAL or NTSC black burst or composite sync signals are recommended.
Genlock is highly recommended in configurations that utilize video camera
sources.
