4.2 Boards connection
The electrical connection among boards is executed using the following two type of cables:
Display connection
For the connection of the display is necessary to use a cable with 6 wires and RJ11 connectors; the cable is
different from the standard telephone cable because in the display cable the connectors are reversed.
LAN connection
For the LAN connection is necessary to use a cable with 2 wires plus shield, from unit to unit, by using the
terminal strip in the electrical panel (see the specific electrical diagram); the data are sent through Rs485
logic; no additional device is required.

4.2.2 Units connected in LAN (max. 8 units)
The units can be connected to the other units in LAN (local area network) for a maximum of 8 units. Each
unit can be connected (inside of it) to one or two drivers (EVD) for the management of the electronic valves
and to one display for user interface. In the following table are listed the addresses of the microprocessor, of
the drivers (EVD) and of the display.
