ASCII p (or Hex 70)
Selects video input priorities.
The device will ask for the priorities for each of the four
inputs via a prompt the user must respond to.
“In X is [Y] (1-4)?” Where ‘X’ is the Video input and ‘Y’
is its current priority.
Entering ‘0’ for a video input priority will keep the existing
priority.
Priority can range from 1 to 4, 1 being the highest and 4
being the lowest.
For example, if Video #1 priority is set at 1, the unit will
select input #1 automatically whenever the presence of
the video at Video 1 input is detected even if the input
from the Video 2 input is currently playing. If no video is
detected for a specific video input, the next video input is
selected based on the priority setting in order.
