Contact Closure Remote Control
The Remote connector also provides a way to select an input
to the switcher using a remote contact closure device. Contact
closure control uses pins on the Remote connector that are not
used by the RS-232 interface. Figure 3-5 shows the contact
closure pin assignments.

To select a different input number using a contact closure device,
momentarily short the pin for the desired input number to logic
ground (pin 5). To force one of the inputs to be always selected,
leave the short to logic ground in place. The short overrides
front panel input selections.
