Auto-Input Switching - Extron electronics HC 400 Series User Manual

• Tap a button on a TLP Pro Series touchpanel or NBP button panel. This option is
available only if the HCR 102 has been configured using Global Configurator to include
the touchpanel or button panel and to configure its buttons.
The input switch occurs as soon as the button is released or the contact input connection is
made (a Show Me cable button or similar device button is pressed), and the corresponding
front panel LED for that input lights to indicate that the input is selected (active).

Auto-Input Switching

The HC 400 Series systems (the transmitter-receiver pairs) offer the following auto-switching
modes, which can be selected using PCS software:
• 0: disabled (manual switching only)
1: user-defined priority mode
•
When this mode is enabled, the transmitter-receiver system detects which of its inputs
has an active signal and outputs the signal from the active input that has the highest
specified priority level. You can set the priority level of each input by using the PCS
software.
NOTE: As shipped, and after a reset to factory default settings, the default priority
order is: input 1, input 2, input 3, input 4.
• 2: last connected mode (a hybrid of auto and manual switching) (default)
Last connected (hybrid) auto-switching mode is a mode that blends connection priority
and manual switching. For this mode, the HC 400 Series system assigns the highest
priority to the most recently connected, active input, and assigns the lowest priority to
the least recently connected input. Manual input selection overrides this priority.
When a new input source is connected, the system switches to the newly
•
connected input.
When the currently selected input is disconnected, the system switches to the next
•
highest priority input.
When an input is manually selected (using a front panel button, a Show Me cable
•
Share button, contact closure, NBP button panel, or a touchpanel), the system
switches to the manually selected input, and that input moves to the top of the
priority list.
If the system does not initially detect an active signal at the manually selected input,
an auto-switching timeout period (from 0 to 500 seconds, set using PCS software)
begins. The default period is 10 seconds. During the timeout period:
•
•
NOTE: The system (the transmitter-receiver pair) stores and remembers the current
priority order, even if the units are powered off.
If no signal is detected at the manually selected input, the unit switches back to
the previously selected input.
If an active signal is detected at the manually selected input, that input remains
selected and system resets the timeout period. If the signal is lost, the timeout
period begins again.
