RS-422 Cable Wiring The RS-422 standard uses a balanced voltage digital interface to allow 9600 bps communication over cables of up to 400 ft (1.2 km) in length. Ten receivers can be connected to any one driver for broadcasting systems.
Connection Cable and Cable Wiring 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.
Impedance Matching and Termination Resistors For RS-422/485 serial communications, when an electrical signal travels through two different resistance junctions in a transmission line, the impedance mismatch will sometimes cause signal reflection. Signal reflection causes signal distortion, which in turn will contribute communication errors. The solution to this problem is to establish the same impedance at the line ends as in the line itself by terminating them with resistors.
