Remote connectors
Contact input — Connect a locally-constructed contact closure device to the
•
4-pole captive screw connector. The three left ports (1, 2, and 3) are used to select
inputs 1 through 3 when momentarily shorted to the fourth port (G). The closure
accepts a momentary or latching contact.
Tally output — If desired, to remotely identify the currently selected input, plug 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 the each
indicator into the corresponding tally out pin, 1, 2, or 3. When an input is selected,
by either contact closure or front panel selection, the corresponding tally out pin
shorts to ground, closing the circuit and lighting the connected indicator (LED).
TIP: The Contact and Tally connectors can be used with Extron "Show Me"
cables. 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 figure 5). For more information
and installation details for the Extron "Show Me" cable, see the "Show Me"
Cable Series Setup Guide at www.extron.com.
RS‑232 — Connect a 3.5 mm, 3-pole captive screw connector for RS-232 control
•
of the unit (see figure 5 for wiring instructions).
