Connect two KW2M power meters via Ethernet and two KW9M power meters via RS485.
Use a LAN cable to connect the KW2M power meters to the network switch.
Connect the KW9M power meters to the RS485 interface in a daisy chain:
Suitable wire: AWG26-24
We recommend that you install a terminating resistor on both ends of the RS485 connection. On the FP‑I4C side, place a 100Ω resistor between E and R/+. On the second KW9M power meter, place a 120Ω resistor between A+ and B-.
Make the power meter settings:
KW2M:
Set the IP address to 192.168.0.70 and 192.168.0.71 and the subnet mask to 255.255.255.0.
KW9M:
Protocol: MEWTOCOL, baud rate: 19200, parity: Odd (8b - o), station numbers: 1 and 2
