The TC3400 Serial-to-Ethernet Converter series is ideal for connecting surveillance cameras with RS-232 interfaces over Ethernet. It is also frequently used for poll/response networks in Utility, SCADA, Traffic Control and Process Control LANs to link RS-232, RS-422 or RS-485 RTUs and PLCs to a Host CPU.

Hi Bob,Thanks for your reply.If I read and and interpreted your reply above correctly, what you're saying it is actually possible to use use an existing RS485 cable as an Ethernet cable with distances over 100m with the use of a Raspberry Pi hardware, am I right?In my case however, I would want to route the RS485 cable without external hardware directly to my communication device which uses a RJ45 connector. Is that still possible for distances of that great length?I have a previous experience in which I tried using an exsiting RS485 cable as an Ethernet cable for a distance of slightly more than 100m and I am totally unable to ping any devices which the RS485 cable connects to.
In this case, I am not using any form of hardware as well to boost the cable's signal.Any take on this? Hi Bob,Well I surely don't want to risk routing a RS485 cable from one end to the other having the length of about 290m and at the very end it doesn't work out.
I did some research on the kinds of solutions available but they seem to be US-based and I am from the other side of the globe.Another person did suggest to use optical fibre solutions at it would be more feasible to do so with it. Of course if there is a choice, I would want to reduce the costs by using the RS485 solutions instead of optical fibres. It's just that I am not too confident that the 290m distance would work out for me without any use of hardware. As much as possible, my team and I would want to reduce the use of hardware as these hardware does jack up the cost by quite a fair bit.
