locally-constructed device into the 4-pole captive screw connector. Connect the power
wire for the device into the +V pin and connect the ground wire for each indicator in the
corresponding tally out pole (1, 2, or 3).
When an input is selected, by either contact closure or front panel selection, the
corresponding tally out pole 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 connector. For each
Show Me cable, connect the red pigtail to the associated pole
of the contact closure connector and the black pigtail to the
associated pole on the tally out connector (see the diagram to
the right). For more information and installation details about
the Extron Show Me cables, see the Show Me Cable Series
Setup Guide at www.extron.com.
