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.
3.
Use a small screwdriver to tighten the two screws above pin slots 4
and 5 of the plug so that the jumper wire ends remain securely in place
(see the illustration at right).
4.
Insert the plug into the 5-pole Auto-SW captive screw connector on the rear panel.
Figure 9 shows an SW4 HDMI with a jumper connecting pins 4 and 5 to enable
auto-input switching.

and the 5-pole captive screw plug is attached to the Remote connector.
