Remote Tally port
— If desired, to remotely identify the currently selected input, plug a
locally-constructed device into the 5-pole captive screw connector. Connect the power
wire for the device into the +V pin and connect the ground wire for the each indicator
into the corresponding tally out pin, 1, 2, 3, or 4.
When an input is selected, by either contact closure of front panel selection, the
corresponding tally out pin shorts to ground, closing the circuit and lighting the
connected indicator (LED).
This connector can also be used with Extron “Show Me”
cables and the Contact Closure input connector. For each
“Show Me” cable, connect the red pigtail to the associated
pin of the Contact Closure input connector and the black
pigtail to the associated pin on the Tally Out connector (see
the diagram to the right). For more information and installation
details for the Extron “Show Me” cable, see the
“Show Me”
Cable Series Setup Guide

— Connect a host device to the three rightmost poles of
