Overview

ConnexLink stand-alone radio modules are set up in minutes to cut the cables between RS232 or RS485 devices. Their flexibility and economic price allow users to quickly upgrade wired terminals to cordless operation in industrial commercial and residential applications. Powered by a 100mW 2.4GHz radio or a 1000mW 900MHz radio each unit is small and easily portable for use in mobile and temporary settings as well as fixed installations. Optional software enables custom configurations based on user needs. ConnexLink implements a proprietary communication protocol to provide secure local data transmissions. Because it uses FHSS technology the data remains reliable over distances of up to 20 miles (32 km) line-of sight (900MHz version). Use of license-free frequency bands ensures that units are ready to use with no further certification requirements. Every unit is backed by a full one-year warranty. ConnexLink radio modules provide simple elimination of cables with a wireless link replacement. Every unit is backed by a full one year warranty.

FAQ

Can the RM024 talk to an AC4424?

The RM024 is a follow-on to the LT2510, the PA on the LT2510 went EOL and we were forced to redesign and recertify the module under a different name with the new PA, the RM024.  The RM024 will communicate with LT2510's as they are the same base radio and design, the only difference is the RF output path.  The AC4424/CL4424 was released prior to the LT2510 and uses a different base radio to communicate. Therefore the AC4424/CL4424 will not communicate with LT2510's or the RM024. 

Do we recommend conformal coating your modules?

We highly do not recommend conformal coating the radio module. If you plan on encapsulating the radio module in a potting compound or conformal coating, you must assure that the compound in liquid or solid form does not enter under the shield where there are sensitive RF components. Some of the capacitive and inductance values are as low (pF and nH) and could be sensitive to contacting materials such as potting compounds. There are potting compounds and conformal coatings which have very good dielectric constants and are suitable for 2.4 GHz potting applications, however, when you apply any of these, they were not accounted for in the circuit design and might reduce performance of the device (or all together cause it not to function).  You should run tests on their particular potting compound and evaluate radio's performance and range.  Also, it's worth mentioning that applying any compound, conformal coating or potting directly to the module WILL void the warranty. If your application requires 100% sealing of the radio module, there is a way to do this very successfully without impacting the module performance. Simply place the module on your PCB. Place a plastic cover over the module (like a hat), make the cover large enough to cover the whole module. Apply glue around the bottom perimeter of the cover where it sits on the PCB. This allows the module to function in free air-space while there is a complete seal around it. This information is only for reference and we recommend you should conduct your own testing with your prototype of your end application to find the best suitable fit for your design.  

What is Modem Mode on the CL4x90?

Modem mode on a CL4x90 allows users to transfer the state of the UART signals over the air.

What's the recommended process to clean modules?

The recommended cleanser is "hydrocarbon cleaning oil", which can be used to clean the RF shield and PCB. We do not recommend the use of alcohol as it doesn't work as well and could leave residue on the boards.  

Will the API commands override the check boxes inside the Connexlink Configuration Utility?

Yes, the API mode will always override anything set in the Configuration Utility check boxes.
