Notes
TX LED: Regardless of connectivity or
not, this LED will constantly blink as it
continually looks for devices to
communicate to.
LED not lit:
Determine if, for example, a Tracer SC or
BACnet device is trying to talk to the
controller or if it is capable of talking to
the controller. Also determine if the
communication status shows down all of
the time.
Refer to "Ground Measurements," p. 16
for a check-out procedure.
Press and hold during power up to place
controller into boot code or press and
hold for a count of approximately 10
seconds to clear the Device ID.
What is Boot Code? When the UC400
is placed into boot code, the system
will not run any applications such as
trending, scheduling, and TGP2
runtime.
