Dear list,
We have an application where a RS-422 communication port in a Gas
Chromatograph has to communicate to RS-485 modbus port in a DCS.
Does this conversion require a RS-422 to RS-485 converter or can it be
achieved through some wiring changes. RS-422 port has got 5 pins
(Receive-2 nos, Transmit-2nos and Ground) and the RS-485 has got 3 pins.
(Receive, Transmit and Ground)
The supplier who is responsible for this conversion is not able to give
a clear answer. Any help from you will be highly appreciated.
Thanks in advance
With Warm Regards
