b. Baud Rate
a. Address
Please note the meter is factory-set to match Autometers protocol.
Baude Rate: 9600
Data Format:
Floating point
Parity Type: Even Modbus Type:
RTU
Wire Mode: 2 wire
F.P. High word first
When using RS 485 Modbus it is vital that you understand what management
system the meters will be connected to. Normally every meter must have a unique
address and must not be duplicated.
However, when connecting to Autometers Intelligent Termination Point then all
meters must have the address set at “001”.
