Figure 25: PT-Link II BACNET ® LED Locations
ProtoCessor Module LEDs
Refer to Figure 25 for LED locations. NOTE: If your BACnet module
does not have DIP switches, refer to Figure 27 on page 17.
PWR LED
When the PT-Link II is fi rst powered up, the “PWR” green LED should
light up and stay on continuously. If the LED doesn’t light up, check
that the ProtoCessor is installed correctly and fi rmly connected to the
Base Board.
UNUSED LEDs
15 seconds after powering up, the 4 unused LEDs will turn on solid for
5 seconds, then turn off.
RX & TX LEDs
During normal operation, the “RX” LED will fl ash when a message is
received on the fi eld port of the ProtoCessor and the “TX” LED will
fl ash when a message is sent on the fi eld port of the ProtoCessor The
“TX” and “RX” LEDs work together to indicate that communication
is being established with the desired protocol network. If both LEDs
are blinking, then communication is working properly. If not, check
the protocol network wiring and the baud rate in the confi guration fi le.
RUN LED
The “RUN” LED will fl ash 20 seconds after power up, signifying normal
operation. The Protocessor will be able to access RUINET once this
LED starts fl ashing. During the fi rst 20 seconds, the LED should be off.
SYS ERR LED
The “SYS ERR” LED will go on solid 15 seconds after power up. It
will turn off after 5 seconds. A steady red light will indicate there is a
system error on the ProtoCessor. If this occurs, immediately report the
related “system error” shown in the error screen of the Remote User
Interface to FieldServer Technologies for evaluation.
COMM ERR
The “COMM ERR” LED will go on solid 15 seconds after power
up. It will turn off after 5 seconds. A steady red light will indicate a
communications problem if there is a confi gured node connected to the
ProtoCessor that is offl ine. To establish the cause of the error, go to the
error screen of the Remote User Interface interface.

CONFIG ERR LED
The “CONFIG ERR” LED will go on solid 15 seconds after power
up. It will turn off after 5 seconds. A steady amber light will indicate a
confi guration error exists in the active confi guration. See the Error Screen
in the Remote User Interface for a description of the confi guration error.
NODE OFFLINE LED
The “NODE OFFLINE” LED will go on solid 15 seconds after power
up. It will turn off after 5 seconds. If the Node Offl ine LED stays on
solid, a node offl ine condition has occurred.
NOTE: If all of these tests are made and the controller still doesn’t
operate, please contact WattMaster Controls Technical
