The CL4490 configuration software enables custom configurations based on unique application requirements. This document contains information about the hardware and software interface between a Laird CL4490 transceiver and an OEM host. Information includes the theory of operation, specifications, serial interface definition, security information and mechanical drawings.
Note: A client’s Link LED lights when in range of the server. It is always lit on a server. Green When flashing, the CL4490-PRO is receiving data. When flashing, the CL4490-PRO is transmitting data.

Each network should consist of only one server. Two servers should never use the same RF Channel number in the same coverage area – the cross-talk between the two servers severely hinders RF communications. For those applications requiring collocated servers, Laird recommends using the Sync to Channel feature, further explained in Appendix II: Sync to Channel.

Version 3.0 CL4490 Security Features In addition to FHSS technology, Laird 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 (download the...

Note: For a period of five (5) years from the date of purchase, Laird warrants the transceiver against defects in materials and workmanship. Laird will not honor this warranty (and this warranty will be automatically void) if there has been any: (1) Tampering, signs of tampering, or opening the transceiver’s case.

In severe cases, you could lose communications all together depending on how much bandwidth your system requires. Due to crystal differences between the servers, you may see intermittent interference. Sync to Channel is pictured in Figure 7 Figure Laird Technologies Americas: +1-800-492-2320 Option 2 Europe: +44-1628-858-940 Hong Kong: +852-2923-0610 www.lairdtech.com/ramp...
