Info
RS485 Wiring
  • For correct RS485 wiring: Follow the guidelines for RS485 wiring.
  • If the wiring shown in the table below is incorrect, please let us know.
  • There is no general consensus in the industry about the usage of A and B for the RS485 polarity, so it may be counterintuitive and opposite of what you might expect for some devices.
