203GT controller can be connected to the MODBUS, RS-485 or
LON bus. When the EH-203/GT controller is connected to the bus,
a (Modbus-200, EH-485, or LON-200 card) bus adapter card (optional
equipment) is installed. Detailed instructions for installing and
initializing the bus adapter card are provided.
When connecting the controller to the LON-field bus, LON-bus
initialization occurs in the controller's special maintenance mode.
Other buses do not have to be initialized from the controller.

LON initialization:
In this special maintenance mode you can
control the Neuron processor's service pin
which is on the LON-200 card so that the
Neuron sends the bus its own identification (48
bit Neuron ID). This procedure is necessary
when initializing 203GT + LON-200 into the
facility's LON net
.
Directions for entering the
maintenance mode are on page 19.
