The Remote connector also provides a way to select an input using a remote
contact closure device. Contact closure control uses pins on the RS-232
connector that are not used by the RS-232 interface (see preceding 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).
Latching the pin to ground results in resetting the corresponding input.
