Input connectors — Connect host devices, such as computers, to these female

type B USB connectors, using cable lengths of up to 15 feet (4.5 m). Pinouts

for these connectors follow the standard pinout as dened in USB standards.

RS-232 port — Connect a host computer or control system to this three-pole,

3.5 mm captive screw connector for RS-232 control and status feedback (see

“Wiring for RS-232 Communication”, later in this chapter). The SW USB can

be controlled via Extron’s Simple Instruction Set (SIS

™

) commands. This port

can also be used to update ﬁrmware.

Your RS-232 computer or control system should not be one of the host

devices connected to the input ports. Use a separate computer for RS-232

communication.

Contact port — If desired, connect a two- or four-button contact closure

device to this 3-pole (SW2) or 5-pole (SW4), 3.5 mm captive screw connector

to enable input selection via contact closure (see “Contact Closure Control”,

later in this chapter).
