• Pins 4 and 5 if jumpered/shorted together will turn the auto-
switching mode on. When the auto-switching mode is on,
the switcher automatically switches to the input that has an
active sync signal.
If both inputs have an active sync signal present, the
highest input, input 2, will be used, and the input 2
indicator LED will light. If no active sync signal is present,
neither input indicator LED will light.
Auto-switching overrides manual input selection. If
auto-switching is on, contact closure and front panel
input selection will be disabled.
• If pins 4 and 5 are not connected, manual switching is
enabled. Selections can be made via the front panel
selection switches and the contact closure device.
If no active sync signal is present, the input 2 indicator LED
will still light.
