LED Indicators
The LAN Controller uses seven LEDs to indicate the status of the controller
and the different networks connected to the controller. The following table
lists the LEDs and their functions.

LED Function
Tier 1 This green LED indicates the status of the MAIN EIA–485 network.
This LED blinks whenever the controller is transmitting data.
Tier 2A This yellow LED indicates the status of the Tier 2 A EIA–485
network. This LED blinks whenever the controller is transmitting
data.
Tier 2B This yellow LED indicates the status of the Tier 2 B EIA–485
network. This LED blinks whenever the controller is transmitting
data.
Ethernet Tx This green LED blinks when the controller is transmitting data to
the Ethernet network.
Ethernet Rx This green LED blinks when the controller is receiving data from
the Ethernet network.
Ethernet Collision This red LED blinks when there is a collision of data packets on
the Ethernet. While collisions are normal, excessive collisions
indicate a problem somewhere in the network.
Power The green power LED indicates the status of the controller:
Steady Blink – If the controller is operating normally, the LED
blinks at a steady rate.
Dark/Not Lit – If the LED is not lit, it may indicate the controller is
locked or does not have power. You can try resetting the controller
or you can reload the panel information using the KMC Flash
Wizard.
Erratic or Repeating Pattern Blink – If the LED is blinking, but not
at a steady rate, the controller is indicating there is a problem with
the license. Contact KMC Controls for assistance.
