Message problems
Blank display seen after boot-up
A blank display is normal after the boot-up procedure. When finished, the display
will be blank except for a flashing pixel in the lower right corner. The display is then
waiting for a message to be sent.
LED flashes in the lower right corner
The flashing pixel indicates that the display is receiving power and waiting for a
message to be sent. Once a message is sent, the flashing pixel should be replaced
with the message.
Message only shows up on one side of the display
Determine if the displays are set up as two primary displays or one primary and one
mirror display. To do this, turn off the power, then turn it back on and observe the
two display faces.
If the set-up involves two primary displays, one should show “HW001” and the other
“HW002”.
