Contact Closure Control
The rear panel Remote Contact port (see
on page 4) provides a way to select
an input to the switcher using a remote contact closure device. The contact closure pin
assignments are shown on page 4.
NOTE: The switcher must be in normal (manual) mode.
To select a different input number using a contact closure device, momentarily short the pin
for the desired input number to ground. To force one of the inputs to be always selected,
leave the short to ground in place. The short overrides front panel input selections.
