CL4490 User’s Manual
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 standard
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.
1.1
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-to-
Peer 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. Upon
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.
