Hello ,
I power RS485 from an Isolated power supply which is not referenced to the Earth ground. I use the same ground return wire from each node as my supply. I want to know if the communication will run smoothly without any reference to the ground. I have no galvanic Isolation here as I think there is no need for it as I have no different ground connections I run a GND cable to each node along with the twisted pair +Rs485 ,-Rs485 .I want to ask will MAX485 work well in this application .I have a network length of approximately 100 Feet .I do someting wrong kindly letme know .
Warm Regards
