Pin RS-232 function
The Remote connector also provides a way to select an input using a remote
contact closure device. Contact closure control uses pins on the Remote
connector that are not used by the RS-232 interface (see preceding the table).
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.
