a Input connectors — Connect host devices, such as computers, to these female USB
type B connectors, using cable lengths of up to 15 feet (4.5 m). Pinouts for these
connectors follow the standard pinout defined in USB standards.
b RS-232 port — Connect a host computer or control system to this 3-pole, 3.5 mm
captive screw connector for RS-232 control and status feedback (see “Wiring for
RS-232 Communication” on page 8). This port can also be used to update firmware.
NOTE: The computer that you use for RS-232 control should not be one of the
host devices connected to any of the input ports.
c Contact port — If desired, connect a two- or four-button contact closure device to this
3-pole (SW2) or 5-pole (SW4 models), 3.5 mm captive screw connector to enable input
selection via contact closure (see “Setting Up Contact Closure Control” on page 9).
d RS-232 Pass Thru port — If desired, connect an Extron AV switcher to this 3-pole,
3.5 mm captive screw connector (see “RS-232 Pass Thru port” on page 9). Commands
issued via the front panel, contact closure, or an RS-232 interface on a PC or control
system can be sent through this port to the connected AV switcher.
NOTE: Only Extron products can be controlled via this port.
