Figure 27: PT-Link II BACNET ® LED Locations
ProtoCessor Module LEDs
Refer to Figure 27 for LED locations.
NOTE:
If your BACnet module
has DIP switches, refer to Figure 25 on page 16.
PWR LED
When the PT-Link II is fi rst powered up, the “PWR” 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.
GPI05 LED
The “GPI05” LED will light up when the Base Board and the
ProtoCessor Module have established communications. This can
take up to 3 minutes depending on the number of units connected to the
PT-Link II. If it fails to light up after 3 minutes, check that the ProtoCes-
sor is installed correctly and fi rmly to the Base Board.
LB LED
Once the unit is powered up, the “LB” LED must be blinking constantly.
If this LED is constantly on or off, the Module is not working properly
and needs to be replaced.
LA LED
Once the unit is powered up, the “LA” LED must be blinking constantly.
If this LED is constantly on or off, the Module is not working properly
and needs to be replaced.
TX & RX LEDs
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.
D14 & D15 LEDs
The “D14” and “D15” LEDs work together to indicate that commu-
nication is being transmitted and received from the USB Port when
performing an update to the PT-Link software.
NOTE:
If all of these tests are made and the controller
still doesn’t operate, please contact WattMaster
