RS-232C

RS-422

The wiring in the terminal resistance must be 330 Ω. To improve the stability of communication, devices should connect through SG, using STP cables. Shielded cables must be earthed.

RS-485

The wiring in the terminal resistance must be 120 Ω. When using RS-485, connect SDA and SDB, but disconnect RDA and RDB. To improve stability of communication, devices should connect through SG, using STP cables. Shielded cables must be earthed.
