Step 7 — Connect RS-232
• SW2 and SW4 DVI Plus (non-audio) models: Connect an RS-232 cable
from your computer to this female 9-pin D connector. Protocol for this
port is 9600 baud, 8 data bits, 1 stop bit, no parity. Wire the connector as
follows: pin 2 = Tx, pin 3 = Rx, pin 5 = Gnd.
• All other models:
Connect a bare wire-to-female
9-pin D RS-232 cable to pins 1, 2,
and 3 of one of the 5-pole captive
screw plugs. Insert the plug into
the Remote/Auto-SW shared
connector, and connect the cable to
the computer’s serial port. See the
illustration at right.
Step 8 — Wire power
connector
If using a different 12 V, 1 A external
power supply from the one that is
included (already wired), attach the
provided two-pole captive screw
connector to the power supply as
shown below.
Step 9 — Power on
