Your computer locates the driver needed for it to communicate with the SW HDMI via
the USB port and loads it to the computer hard drive.
4. When the Completed screen appears, click Finish to close the wizard.
NOTE: This wizard appears only the first time you connect the SW HDMI to each
USB port. You do not see the wizard again unless you connect the switcher to
a different USB port on your computer.
5. Configure the switcher as desired using SIS commands (see the Remote
Communication and Control section, beginning on page 21 for information on
available commands).
Enabling Auto-input Switching
You can set up the SW HDMI to automatically select the active, connected input based on
detection of an active video signal (TMDS clock activity). If two or more inputs are active,
the highest-numbered input port with an active signal is selected (for example, input 4 on
an SW4 HDMI switcher). When auto-input switching is in effect, the green Auto Switch
LED on the front panel lights and the front panel input buttons are disabled.
To enable auto-input switching:
1. Cut a small piece of wire to use as a jumper.
2. Insert the ends of the wire into slots 4 and 5 of the provided 5-pole captive screw
plug, connecting pins 4 and 5 together.
