ADL400 - Communication Description

The meter adapts MODBUS-RTU protocol, and the baud rate can be chosen from 1200bps、2400 bps、4800 bps、9600bps、
19200bps and 38400 bps. The parity is None.
The meter needs shielded twisted pair conductors to connect. Customers should consider the whole network’s parameters
such as communication wire length, the direction, communication transformer and network cover range, etc.

Note:
1. Wiring should follow the wiring requirements;
2. Connect all the meter in the RS485 network even some do not need to communication, which is benefit for error
checking and testing.
3. Use two color wires in connecting wires and all the A port use the same color.
4. No longer than 1200 meters of RS485 bus line.

1.1 ADDR List

MODBUS-RTU protocol has 03H and 10H command to read and write registers respectively. The following chart is registers’
