Hi this is jude from innospace automation.Our application will collect the data from energy meter through rs485 interface.
Here we are using ISOW1412DFMR for RS485 interface.In datasheet Page No 37 - Figure 11-2. The Master GND2 pin is connected with all the devices GND2 pin which is in RS485 network(Image attached
In our design We have to connect the ISOW1412 chip's A and B with energy meter which has only A(D+) and B(D-) line only
Will any communication issue occur, if not connecting the GND2 pin with energy meter
Kindly give me the solution to connect the ISOW1412 with energy meter
