Supported Devices

Device Type	Modbus TCP (Ethernet)	RS485
UPM209	✅	✅

For correct ethernet wiring: Follow the the guidelines for ethernet wiring.

For correct RS485 wiring: follow the RS485 wiring guidelines.
If the wiring shown in the table below is incorrect, please let us know.
There is no general industry consensus on the use of A and B for RS485 polarity, so the naming may be counterintuitive for some devices.

SmartgridOne Controller model OM1	SmartgridOne Controller model IG8	RS485-USB converter	RS485-Ethernet converter
RS485 A	RS485_POS	RS485 A	TX+
RS485 B	RS485_NEG	RS485 B	TX-
RS GND	GND	Not available	G

Set the modbus address on the meter. (Baud rate and parity can also be set, but we recommend leaving this to the default.)

If connected through ethernet, you may have to adjust the IP address settings of the energy meter .
