With the credentials updated in Edge Lite and the WAN port enabled on the TRB246, follow the connection layout below to connect the TRB246 device to the Conzerv EM6400NG energy meter.

Power off the TRB246.
Connect Pin 14 of the EM6400NG to the D+ pin of the RS485 port on the TRB246 using an RS485 cable.
Connect Pin 7 of the EM6400NG to the D– pin of the RS485 port on the TRB246 using an RS485 cable.
Connect the D+ pin to the A+ pin in the RS485 port of the TRB246 using a wire.
Connect the D– pin to the A– pin in the RS485 port of the TRB246 using a wire.
Connect the positive and negative wires of the power adapter to the corresponding + and – terminals of the RS485 port on the TRB246.
Connect the positive line wire to Pin 13 and the negative live wire to Pin 12 of the EM6400NG.
