Terminate cables at both ends with RS-485 terminators (hardware has on-board terminators for RS-485 termination).6. Terminate cables at both ends with RS-485 terminators (hardware has on-board terminators for RS-485 termination).7. Always use the signal ground (SG) connection. Carefully insulate the SG wire for a reliable installation. Use 24 GA plastic sleeving over the SG wire when terminating the cable to the 5-position insulation displacement mating connector.
