The following table describes the operation of the LEDs located on the AFI5100 :
LED Brief Description
POWER The POWER led is illuminated when power has been applied to the device.
ACTIVITY The ACTIVITY led indicates that the AFI5100 is accessing information con-
tained in its internal database or performing a routine operation.
This LED also indicates whether the initial instruction set has been downloaded.
If power is applied and the LED blinks quickly, the AFI5100 instruction set (firm-
ware) needs to be downloaded. If the LED is blinking slowly, approximately
once per second, a firmware set has already been downloaded.
Tx COMMS The Transmission COMMS LED flashes when the IPM is sending data to the
ACC to which it has been connected (via an FLN).
Rx COMMS The Transmission COMMS LED flashes when the IPM is receiving data from
the ACC to which it has been connected (via an FLN).
Inputs The tricolor Input Port LEDs indicate the current status of the input port. See the
table below for an explanation of the colors.
Outputs Each Output Relay has a corresponding LED that is illuminated when the relay
is activated.
