RS-485 Cable Wiring

The RS-485 standard is an enhanced version of the RS-422 balanced line standard. It allows multiple drivers and receivers in a multidrop systems. As many as 32 drivers and 32 receivers can be put on any multidrop system.

The Industio CP-114 Series supports only 2-wire half-duplex RS-485 communication. Data+/- pins are served for both data transmitting and receiving, depending on the RTS signal.
