The BACnet communication module has a BSP LED and a
BUS LED to indicate communication activity and status of the
BACnet communication module. These indicators are visible
when the communication module is connected to the unit
controller and the unit is powered on.
BSP LED
The BSP LED indicates the communication status between the
BACnet communication module and the unit controller. Table 1
describes the status of the BSP LED.

BUS LED
The BUS LED indicates the communication status between the
BACnet communication module and the BACnet IP network.
Table 2 describes the status of the BUS LED.

An RJ45 connector connects the BACnet communication
module to the IP Network.
The board-to-board connector connects the unit controller to
the BACnet communication module (Figure 3 and Figure 4).
