Hi there, Joe. I have been using simple cat-5 cable for much of my RS-422 data=20 communications. You get two separate RS-422 streams (each stream=20 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=20 quality twisted-pair cable. The fact that all four pairs are inside=20 a single jacket is simply irrelevant most of the time. I use the cable for both RS-422 / RS-485 communications and balanced=20 audio at line level (+4dBu). Crosstalk between pairs is simply not=20 audible when using it for audio. I haven't had any data corruption=20 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).
