LINC Gateway consists of two printed circuit
boards.

TABLE 4: SIMPLICITY
RS485 BOARD (Bottom)
Normal Board Operation
The PWR LED should be on during operation. The RX and TX
LEDs should flash when a signal is either received or sent.
Faulty Board Operation
If the PWR LED does not come on but the RX and TX flash, then
the PWR LED is broken.
If the TX and / or RX LEDs do not flash, it may represent a problem
with the field wiring or configuration problems in the field side of
the BacNET board. It may also indicate incorrect polling
parameters such as baud rate or parity.

LINC GATEWAY
Normal Board Operation
LEDs LA and LB flash about once per second. LED GP105 will
remain on within 45-60 seconds after power up, signifying normal
operation. The PWR LED should be on during operation. The RX
and TX LEDs should flash when a signal is either received or
sent.
Faulty Board Operation
If the PWR LED does not come on but the RX and TX flash, then
the PWR LED is broken.
If the TX and / or RX LEDs do not flash, it may represent a
problem with the field wiring or confguration problems in the field
side of the BacNet board. It may also indicate incorrect polling
parameters such as baud rate or parity.
If the PWR LED does not come on and LA and LB do not flash,
call UP Tech Services at 1-877-874-7378.
If GP105 never comes on, call UP Tech Services at
1-877-874-7378.
