CL4424 User’s Manual

1. CL4424 RF Transceiver

The CL4424 transceiver is a Frequency-Ho pping Spread Spectrum ( FHSS) radio designed for
license-free operatio n in the 2.4GHz ISM band. Out-of-the box, the radio susta ins a standard
asynchronous serial data stream between two or more radios. Housed in a compact and rugged
die-cast enclosure, the radio is equipped to re pl ace thousands of meters of serial cable with its
wireless link. The radio features an RS-232 or RS-485 interface for integration into legacy data
systems.

Features

 Durable Industrial grade en closur e
 Transparent operation, supports any legacy system
 Transmits around corners, through walls
 Reliable communication up to 115.2Kbps

1.1 Overview

The CL4424 uses Frequency Hopping Spread Spectrum modulation, where the units “hop ” from
frequency to frequency many times per second using a specific hop pattern applied to all the
transceivers in the same network. A distinct hopping pattern is provided for each Channel
Number, thereby allowi ng multiple networks to co-exist in the same area without interference.

CL4424 transceivers operate in a Point-to-Point or Point-to-Multipoint, Clie nt-Server or Peer-to­Peer architecture. One transceiver is configured as a Server and there can be one or ma ny
Clients. To establish sync hronization betwee n transceivers, the Server emits a beacon. Upon
detecting a beacon, a Client transceiver informs its Host and a RF link is established.

CL4424s implement a pr oprietary communication protocol to provide secure data transmissions.
Using FHSS technology, the data r emains reliable over long distances. The us e of license free
frequency bands ensures that the units are ready to use with no further certification
requirements.

Each unit is small and easily portable for use in mobile and temporary settings as well as for fixed
installations. The CL4424 configuration software enables cu stom configurations based on unique
application requirements.
