1.3CL4424 Interface

CL4424 transceivers support RS-232/ RS-485 (2-wire Half Duplex) protocols. In a cabled environment, the RS-485 protocol can tolerate high noise and push signals over long cable lengths. RS-485 cabling can also communicate as far as 4000 feet (1200m) and offer multi-drop capability where up to 32 nodes can be connected. RS-232 cabling is suitable for distances less than 100 feet (30.5m) and only supports point-to-point communications. CL4424 transceivers offer performance improvements over a standard cabled link. Distance and multipoint communications are greatly enhanced. A selection of RS-232/RS-485 can be made when ordering the CL4424s.
