-485/422 C
The RS-485/422 protocol provides a solution for wired communications that can tolerate high
oise and push signals over long cable lengths. RS-485/422 signals can communicate as far as
4000 feet (1200 m). RS-232 signals are suitable for cable distances up to 100 feet (30.5 m).
odes can be connected. The RS-422
Suggestions for integrating the XStream Module with the RS-485/422 protocol:
n
RS-485 offers multi-drop capability in which up to 32 n
protocol is used for point-to-point communications.
