WebSep 30, 2024 · Use shielded CAT5, CAT5e, or CAT6 cable when you can. These cable have 4 twisted pairs of wires in them. Each RS-485 connection will use one of the twisted pairs. Shielded cable protects the communications in electrically noisy environments. When making wire connections it is a good idea to apply dielectric grease to the connection … Web5 Cable Type. RS-485 applications benefit from differential signaling over twisted-pair cable, because noise from external sources couple equally into both signal lines as common-mode noise, which is rejected by the differential receiver input. Industrial RS-485 cables are of the sheathed, unshielded, twisted-pair type, (UTP), with a characteristic

WebMaxim Integrated MAX14945 RS-485/RS-422 Transceiver provides 2750V RMS (60s) of galvanic isolation between the cable side (RS-485/RS-422 driver/receiver side) and the UART side of the device. Isolation improves communication by breaking ground loops. It also reduces noise when there are large differences in ground potential between ports. WebMar 19, 2024 · Connecting the shield to signal ground kind of defeats the purpose of having a signal ground in the first place. The shield can always be connected to some "dirty" ground like case or supply. Apart from that, the way you describe 1) is the de facto standard way to wire RS-485. – Lundin Apr 24, 2024 at 8:50 Add a comment 1 Answer Sorted by: 2

Web• Number of conductors: RS-485 is a three wire bus. One twisted pair is required for the two data signal wires, plus an additional wire for a common reference, which does not need to be twisted. Although the shield can be used for the common reference, it is preferable to use a separate wire for the common.
