Auto Mode

Auto Mode 1 (priority mode): VGA- >DP->HDMI1->HDMI2

When power is applied to the switcher it will default to the VGA channel unless there is another active source connected. If multiple sources are already connected it will auto-switch to the active source with the highest priority.
When a new source is connected the switcher will auto-switch depending on the priority of the input signals.
When a currently selected source is removed the unit will auto-switch to the next lower-priority input.
Manual and API switching is also valid in the Priority Mode. The front panel button will switch through the active sources. Any switch command via the Contact Closures inputs or API commands will be performed on inputs with active sources only. If the selected source is not active the LED indicator will flash twice to indicate the source is not active and will not switch.

Auto Mode 2 (Last Connected):

When power is applied to the switcher it will default to the VGA channel. If multiple active sources are present at power up the unit will auto-switch to the input with the highest priority.
When any new active source is connected the unit will auto-switch to this source.
When a currently selected source is removed the unit will auto-switch to the active source with the highest priority, or remain on the current input if no active sources are present.
Manual and API switching is also valid in the Last Connected Mode. The front panel button will switch through the active sources. Any switch command via the Contact Closures inputs or API commands will be performed on inputs with active sources only. If the selected source is not active the LED indicator will flash twice to indicate the source is not active and will not switch.
