    Scientific, and Medical (ISM) unlicensed band. The radio sustains a standard asynchronous serial data stream between two or more radios out of the box. Housed in a compact and rugged die-cast enclosure, the radio is equipped to replace miles of serial cable using a CL4490 RS232, RS485, or USB interface.

    Note: A client’s Link LED lights when in range of the server. It is always lit on a server. Green When flashing, indicates the CL4490 is receiving data. When flashing, indicates the CL4490 is transmitting data. 2.2 CL4490-PRO Figure 2: CL4490-PRO Status LEDs Note: DIP Switches only appear on the CL4490-PRO.

  • Page 8: Theory Of Operation

    RF Architecture The CL4490 utilizes a server-client network where all clients synchronize their hopping to the server. The server transmits a beacon during the first 1 ms of every hop (20 ms). The client transceivers listen for this beacon; upon hearing it, they synchronize their hopping with the server and the LINK LED illuminates.

    Once in Command mode, all data received by the radio interprets as command data. Command Data may exist as either EEPROM Configuration or On-the-Fly commands. For more information on On-the-Fly commands, download the AC4490 Embedded Module User Manual. https://www.ezurio.com/ Americas: +1-800-492-2320 © Copyright 2024 Ezurio Europe: +44-1628-858-940 All Rights Reserved Hong Kong: +852-2762-4823...

    The 4490 product family utilizes a Frequency Hopping Spread Spectrum (FHSS) technology, which provides the foundation for secure digital wireless communications. The purpose of this section is to take a brief look at how spread spectrum technology works and explain how an OEM enables specific security features available in the CL4490. https://www.ezurio.com/ Americas: +1-800-492-2320 ©...

  • Page 12: Spread Spectrum History

    CL4490 Security Features In addition to FHSS technology, Ezurio has implemented three levels of security in the CL4490. All three levels associate with their own EEPROM parameter that you may program for permanent operation or change during system operation in volatile memory using on-the-fly commands...
