enables the sync to be properly passed from input to selected output(s).
The matrix switchers have two sets of sync termination switches; one for
horizontal or combined sync and a second set for vertical sync.

The CrossPoint UltramatrixswitchershaveSyncterminationswitchesfor
inputs1through4.

An input that produces an out of sync display, a display that is rolling vertically
and/or tearing horizontally, could indicate a non-TTL sync input.
A device that is known to output non-TTL sync levels (greater than 5V p-p)
should be connected to one of the inputs with sync termination switches, and the
switches for that input should be set to the 75 ohm position. If you are not sure,
check the specifications in the user’s manual for the input device.
