BUS CONNECTIONS/ LON INITIALIZATION
T
he Ouman EH-105 controller can be connected to the MODBUS,
RS-485 or LON bus. When the EH-203 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.

In this special maintenance mode you can
control the Neuron processor's service pin
which is on the LON-100 card so that the
Neuron sends the bus its own identification (48
bit Neuron ID). This procedure is necessary
when initializing EH-105 + LON-100 into the
facility's LON net
.
