I have a RS-485 device connected via twisted pair to another RS-485 device.
I'd like to bridge the distance via Ethernet, like so:
RS485 > Ethernet > RS485
Is this possible with two RS485 to Ethernet converters?
[RS485 device] to [RS485-Ethernet] via cable to [Ethernet-RS485] to RS485
The RS-485 communication is bi-directional. As in, the master sends and asks for information. I thought of getting two USR-RS232-304 devices, which I'd like to use for this. Would these work for this purpose? What puzzles me is, one seems to be a server, the other client. Will this still allow for bi-directional comms on the RS-485 side?
I did read the manual, and while it describes the general setup of IP config and transmission parameters, I am not sure (or could not deduct from it), whether bidirectional RS485 would work or not.
Any diagrams I have seen show only one of these converters, with the other end being a virtual comport. The devices I have talking to each other are not computers, where I could load a virtual COM port; hence, my query.
Maybe someone has done exactly what I am after and can share.
