B

RS-232 port — Connect a host computer or control system to

 

this three-pole, 3.5 mm captive screw connector is used for RS-

 

232 control and status feedback. The SW USB can be controlled

 

via Extron’s Simple Instruction Set (SIS) commands. This port

 

can also be used to update firmware.

 

N 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.

C

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

 

closure device to this three-pole (SW2) or five-pole (SW4),

 

3.5 mm captive screw connector to enable input selection via

 

contact closure.

D

RS-232 Pass Thru port — If desired, connect an Extron A/V

 

switcher to this three-pole, 3.5 mm connector. Commands

 

issued via the SW-USB front panel, contact closure, or an RS-232

 

interface on a PC or control system can be sent through this port

 

to the connected switcher.

 

N Only Extron products can be controlled via this port.

E

Emulation DIP switches — (SW4 USB Plus only) These DIP

 

switches enable host emulation to a keyboard and/or mouse

 

connected to output ports 3 and 4. Switch 1 enables host

 

emulation to a mouse; switch 2 enables emulation to a keyboard.

 

When a keyboard or a mouse is connected to port 3 or 4, and

 

the appropriate switch is set to on, the SW USB switches to

 

the connected keyboard or mouse instantly, without the delay

Wiring the Power Connector

If using a different external power supply from the one provided with the SW USB, you may need to wire the connector for it.

To wire the power connector,

1. Cut the power supply’s DC output cord to the length needed.

2. Strip the jacket to expose 3/16" (5 mm) of the conductors.

CExposing more than 3/16” (5 mm) of the copper wires could allow the stripped wires to touch each other, causing a short circuit. This could result in the external DC power supply overheating and/or burning.

Exposing less than the recommended amount may cause the wires to slide out of the connector too easily, even if they are tightly pinched by the captive screws.

3. Slide the exposed leads into a two-pin captive screw plug and secure them by tightening the screws, using an Extron Tweeker or other small screwdriver.

4. To verify the power cord’s polarity before connecting it, plug in the power supply with no load and check the output with a voltmeter.

5. Use the supplied tie-wrap to strap the power cord to the extended tail of the connector.

Output connectors — Connect peripheral USB devices, such as

 

keyboards and/or mice, to these female type A USB connectors,

 

using cable lengths of up to 15' (4.5 m). All outputs supply the

 

500 mA, 5V rating as defined in USB specifications.

 

N The four outputs act as a USB hub. Inputs cannot be

 

routed to specific USB output connectors. All outputs

 

are simultaneously connected to the selected input.

 

N On the SW USB Plus, output ports 3 and 4 can be used

 

for host emulation. See “Host emulation (SW4 USB

 

Plus only),” in chapter 3, “Operation”, for more

 

information.

WThe two power cord wires must be kept separate while the power supply is plugged in. Remove power before wiring.

CDo not tin the stripped power supply leads before attaching the captive screw plug to them. Tinned wires are not as secure in the captive screw connectors and can be easily pulled out. They may also break after being bent several times.
