The RS485 LED (right) indicates the status of communication with the BACnet MS/TP network
(RS485). The LED shows the following information:
Starting sequence: on power-up or after rebooting PCOnet, the RS485 LED switches in the
following sequence:
• Off for approximately 50 seconds;
• Approximately 50 seconds after restarting PCOnet: slow green–red–green–red: at
the end, BACnet will be active.
Status of communication with the BACnet MS/TP network: once the starting sequence has been
completed, the RS485 LED flashes to indicate the quality of communication with the BACnet
MS/TP network:
• Green with occasional red flashes if communication is OK (BACnet MS/TP meaning:
green ON = PCOnet keeps the Token (control of the MS/TP network); green OFF =
PCOnet DOES NOT keep the Token; red on = Poll-For-Master, search for a Master to pass
the Token to)
• Green and red ON together (BACnet MS/TP meaning: continuous Poll-For-Master):
communication not established (connection problems, or no network device found); this
may depend on electrical connection difficulties or communication settings that are not
compatible with the other network devices connected. See the section on configuration.
The Pushbutton Function
• restart PCOnet
• recall the factory configuration
Restarting PCOnet
With the board on and in stable operation (Status LED flashing continuously), hold the
button for more than 5 seconds and no more than 10 seconds. Approximately 10
seconds after releasing the button, the Status LED will stop flashing, and 15 seconds
later PCOnet will be restarted: Status LED quickly flashing red-green-red-green.
