swapped.
Check power to Quad Input Manager Module.
If you see more than one address LED lit (the
ones on the circle) the system is doing an
automatic update. Wait up to 20 minutes for it
to complete. Do not turn off power during
this time.
You must have one and only one 'A' Quad
Module.
If the LED is red, there is Comm connection
but not video connection.
It can take up to a minute for this LED to
reflect the state of the system—you may need
to wait if you have just turned on or changed
connections.
