Wiring the Power Connector

If using an external power supply other than the one provided with the SW USB, you may
need to wire the connector for it.
WARNING:
To wire the power connector:

Emulation DIP switches — (SW4 USB Plus only) These DIP switches enable host
emulation to a keyboard and 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 Plus 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, mice,
storage drives, or webcams, to these female USB type A connectors, using cable lengths
of up to 15 feet (4.5 m). All outputs supply the 500 mA, 5 V rating defined in USB
standards.
NOTES: • 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
[SW4 USB Plus
Power connector — Attach the provided external 12 VDC power supply to this 2-pole,
3.5 mm captive screw connector (see
The two power cord wires must be kept separate while the power supply is
plugged in. Remove power before wiring.
Cut the DC output cord of the power supply to the length needed.
Strip the jacket to expose 3/16 inch (5 mm) of the conductors.
CAUTION: Exposing more than 3/16 inch (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 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.
Slide the exposed leads into a 2-pole captive screw plug and secure them by tightening
the screws, using a small screwdriver.
To verify the polarity of the power cord before connecting it, plug in the power supply
with no load and check the output with a voltmeter.
