SW USB Series • Installation

PRELIMINARY

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

3-pole, 3.5 mm connector (see “RS-232 Pass Thru port”, later in this chapter).

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

switcher.

Only Extron products can be controlled via this port.

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 that normally occurs while the computer

recognizes a new peripheral device.

Output connectors — Connect peripheral USB devices, such as keyboards

and/or mice, storage drives, or webcams, to these female type A USB

connectors, using cable in lengths of up to 15 feet (4.5 m). All outputs supply

the 500 mA, 5 V rating as dened in USB standards.

If your SW USB system contains multiple computers, drivers for all connected

peripheral devices should be loaded on all computers.

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.

On the SW USB Plus, output ports 3 and 4 can be used for host emulation (with

supported keyboards and mice only). See “Host emulation (SW4 USB Plus

only)” in chapter 3 for more information.

Power connector — Attach the provided external 12 VDC power supply

to this two-pole, 3.5 mm captive screw connector (see “Wiring the Power

Connector” in the next section).
