Contact closure input connector — Connect Extron "Show Me" cables or a
J
locally-constructed contact closure device to the 5-pole captive screw connector. The
four left ports (1, 2, 3, and 4) are used to select inputs 1 through 4 when momentarily
shorted to the ground port. The closure accepts a momentary or latching contact.
NOTES:
•
•
In conjunction with the Tally port, the currently selected input can be indicated (see
Remote Tally port
Remote Tally port — If desired, to remotely identify the currently selected input, plug a
K
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 at www.extron.com.
Remote RS-232 connector — Connect a host device to the three rightmost poles of
L
the 5-pole captive screw connector for RS-232 serial control. The scaler uses a protocol
of 9600 baud, 1 stop bit, no parity, and no flow control.

If there is a conflict between a request to change inputs from another method
and the contact closure is currently held closed by a latch, the input does not
switch.
Auto switch mode must be disabled. To disable auto switch mode, use the OSD
menu (see Auto Switch on page 27), SIS commands (see the
mode commands on page 46), or PCS (see
