CL4490 User’s Manual
1.3
The CL4490 supports RS-232/RS-485 (2-wire Half Duplex) protocols. By definition, RS-485
protocol can tolerate high noise and push signals over long cable lengths. When using cables,
RS-485 will communicate as far as 4000feet (1200m) and offer multi-drop capability where up to
32 nodes may be connected. RS-232 cables are suitable for distances less than 100 feet
(30.5m). AeroComm wireless solutions are not subject to the cabling restrictions for distance, but
either interface (RS-232 or RS-485) is available when ordering the CL4490s.
