All the devices in the system are connected through a
single bus (type RS485) for communication by using the
two wires connected to Rc and Rh connections.
Each board can be connected to every point in the
network.
The communication rate is 38400 bauds.
A unique address is assigned to each communication

The addresses range between 1 and 213 and will be
assigned to the boards following the below addressing
