To enable or disable executive mode 2 (see
on the next page for details): press and hold the Menu and Enter buttons for 2 or more
seconds.
To reset the video output rate, hold the down  arrow button for 5 seconds.
In the event that the transmitter powers on but is otherwise unresponsive or
uncommunicative after a failed firmware upload, you can manually boot up the unit to use
the factory firmware code by pressing and holding the Input 2 button while applying
power.
0: disabled (manual switching only) (default)
1: user-defined priority mode
When this mode is enabled, the HC 404 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)
Last connected (hybrid) auto-switching mode is a mode that blends connection priority
and manual switching. For this mode, the HC 404 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 can override 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, or contact closure), 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:
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.
units are powered off.
