Hello Automation List members,
At one of our site our client has provided AB's 1761-NET-AIC convertor (which the document says is a DH 485 to RS232 convertor) for doing a RS485 to RS 232 conversion. We are trying to talk using a modbus RTU protocol between a master and a slave device using this convertor. We are receiving junk data in this case.
We are just using this convertor for RS485 to RS232 hardware conversion.
I would like to know from my knowledgable friends whether DH485 and RS485 mean the same at physical layer. or is there any difference?
Is there any special settings or connection required?
Thanking you in anticipation.
