Auto-Input Switching; Resetting - Extron electronics SW HD 4K PLUS Series User Manual

Auto-input Switching

Auto-input switching allows the SW HD 4K PLUS 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 HD 4K PLUS 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.
Auto-input switch modes
The SW HD 4K PLUS switchers provide three auto switch modes, which can be selected
via SIS commands (see
the PCS help file).
Mode 0 (disabled mode) — Auto-input switching is disabled.
•
• Mode 1 (user‑assigned mode) — The switcher selects the input to which you assign
priority (via SIS commands). If no priority is assigned, the switcher selects the active
input with the highest number (default user selection).
• Mode 2 (input memory priority mode) — The switcher selects the most recently
applied input, and retains a history of the order in which active inputs are connected
to the unit. If an active input is removed, the switcher switches to the most recently
selected input.
Mode 2 timeout — Using SIS commands, you can set the number of seconds (0 to
250) the switcher delays before selecting the most recent input.
Enabling and disabling auto-input switching (modes 0 and 1)
By default, auto-input switching is disabled. To toggle auto-input switching between mode 1
(on) and mode 0 (off):
1. Press and hold input button 1 on the front panel.
2. While holding button 1, press and release input button 2.
To enable input memory priority mode (mode 2) you must use SIS commands (see the
Auto‑input Switch Mode
