RS-485 Communication Network

Appendix C:

RS-485 Communication Network

C.1

RS-485 Overview

By using the RS-485 network capability of the UV detector and additional
software, it is possible to connect up to 32 detectors in an addressable system
with 4 wires only (2 for power and 2 for communication). Using repeaters, the
number of detectors can be much larger (32 detectors for each repeater) up to
247 on the same 4 wires. When using the RS-485 network, it is possible to read
each detector status (FAULT, WARNING, and ALARM) and to initiate a BIT for
each detector individually.

For more details, contact SPECTREX.
