Note:
1. Install AXM-RS485 Module carefully to avoid damage;
2. Under no circumstances should any installation be done with the meter
powered on. Failure to do so may result in injury or death.
5.4.5 Connection Method
The RS485 module is using 2-wire, half-duplex communication mode, which is
the same as the one the onboard RS485 port is using. If the master does not
have RS485 communication port, a converter (such as a RS232/RS485 or a USB/
RS485 converter) will be required. Typical RS485 network topologies include
line, circle and star. The shield of each segment of the RS485 cable must be
connected to the ground at one end only.

The default baud rate of RS485 module is 38400 bps. Users can change the
baud rate in system settings S03 of the Acuvim II series meter.
