DESCRIPTION: The About screen shows the Analog and
Digital boards that have been detected. If a board has lost
communications, a shutdown will be issued. All outputs
are turned off on a Digital Board that has lost commu-
nications. All inputs will get set to their minimum value
range on an Analog Board that has lost communications.
A loss of communications to an analog board results in
sensor fault shutdown message that is associated with
the sensors on that board. If the RX LED on the I/O board
is blinking but the board was not detected on the About
screen, or an I/O Comm failure occurs, check the address
of the board.
