    Wiring for RS-232 Communication RS-232 Port The 3-pole, 3.5 mm captive screw connector labeled “RS-232” is used for optional RS-232 communication between the SW USB and a computer or control system. The control system plugged into this port can issue commands to the SW USB, which can pass the commands through to an Extron AV switcher that is plugged into the RS-232 Pass Thru port.

  • Page 15: Rs-232 Pass Thru Port

    RS-232 Pass Thru Port The RS-232 Pass Thru port loops the signal received at the SW USB RS-232 control port, the Contact (closure) port, or the front panel input buttons through the RS-232 Pass Thru port to send SIS commands to another Extron AV switcher. NOTE: Only Extron products can be controlled via this port.
