RS 485 WIRE COLORS
RS-485 - Wikipedia
Overview. RS-485 supports inexpensive local networks and multidrop communications links, using the same differential signaling over twisted pair as RS-422. It is generally accepted that RS-485 can be used with data rates up to 10 Mbit/s or, at lower speeds, distances up to 1,200 m (4,000 ft).Network topology: Point-to-point, multi-dropped, multi-pointMaximum devices: At least 32 unit loadsPhysical media: Balanced interconnecting cableStandard: ANSI/TIA/EIA-485-A-1998, Approved: March 3, 1998, Reaffirmed: March 28, 2003Overview · Standard · Master-slave arrangement · Full duplex operation
What wire colors are used for RS-485 on a SeaI/O module
Nov 30, 2011White/Blue is RS-485 Data – (Data A) Both Brown and White/Brown are Common (Signal Ground) Note: If you are connecting two SeaI/O modules together, you can simply connect them together using a standard Ethernet patch cable.
