9 Communication description
The meter adapts MODBUS-RTU protocol, and the baud rate can be chosen from 1200bps
、
2400 bps
、
4800 bps
、
9600bps and 19200 bps. The parity is None.
The meter needs shielded twisted pair conductors to connect. Customers should consider the
whole network
’
s parameters such like communication wire
’
s 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 net work even some do not need to communication,
