1. CL4490 RF Transceiver

The CL4490 transceiver is a Frequency-Hopping Spread Spectrum (FHSS) radio designed for
license-free operation in the 900MHz ISM band. Out-of-the box, the radio sustains a standa rd
asynchronous serial data stream between two or more radios. Housed in a compact and rugged
die-cast enclosure, the radio is equipped to replace 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

9 Durable Industrial grade enclosure
9 Transparent operation, supports any legacy system
9 Transmits around corners, through walls
9 Reliable communication up to 115.2Kbps

1.1 Overview

The CL4490 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 allowing multiple networks to co-exist in the same area without interference.

CL4490 transceivers operate in a Point-to-Point or Point-to-Multipoint, Client-Server or Peer-to­Peer architecture. One transceiver is configured as a Server and there can be one or many
Clients. To establish synchronization between transceivers, the Server emits a beacon. Upo n
detecting a beacon, a Client transceiver informs its Host and a RF link is established.

CL4490s implement a proprietary communication protocol to provide secure data transmissions.
As it uses FHSS technology, the data remains reliable over long distances. Use of license free
frequency bands ensure 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 CL4490 configuration software enables custom configurations based on unique
application requirements.

1.3 CL4490 Interface

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.
