I was concerned about crosstalk, particularly at the high speeds. How fast = did you run it? The serial data out of these receivers has no error checkin= g whatever, so any corruption would be a problem.

Subject: Re: [EE] RS232 -> TCPIP -> RS232 Hi there, Joe. I have been using simple cat-5 cable for much of my RS-422 data communicati= ons. You get two separate RS-422 streams (each stream with its own TX & RX= pairs) in a single cat-5 cable. I treat cat-5 cable as if it is simply four pairs of very high quality twis= ted-pair cable. The fact that all four pairs are inside a single jacket is= simply irrelevant most of the time. I use the cable for both RS-422 / RS-485 communications and balanced audio = at line level (+4dBu). Crosstalk between pairs is simply not audible when = using it for audio. I haven't had any data corruption issues either. dwayne At 09:46 AM 9/14/2018, Joe McCauley wrote: >I have some radio receivers which output a data stream at 115K Baud=20 >(RS232).
