Control Connections
I
Contact closure connector (see figure 2 on page 5) — Connect Extron Show Me
cables or a locally-constructed contact closure device to the 4-pole captive screw
connector. The three left poles (1, 2, and 3) are used to select inputs 1 through 3 when
momentarily shorted to the ground pole. The closure accepts a momentary or latching
contact.
NOTE:
Auto switch mode must be disabled. To disable auto switch mode, use the
SIS commands (see the Auto switch mode commands on page 21) or the XTP
Configuration Software (see Auto-input Switching panel on page 38).
In conjunction with the tally connector, the currently selected input can be indicated.
J
Tally Out connector
— To remotely identify the currently selected input, connect a
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 .

Remote RS-232 connector — Connect a host device to the 3.5 mm, 3-pole captive
screw connector for serial control of the switcher.
