The units, all fitted with the serial card, are connected:

• each unit with the RS485 cable;

• last unit with the final resistor;

• first unit with the Gateway.

To realize a local net to be connected to a BMS working with Modbus, it’s necessary:

• 1 gateway LBM every 16 units;

• 1 serial card RS485 for every controller;

• 1 terminal line (120 Ω);

• PC for the gateway configuration.
