What is CRMX™

CRMX is an acronym for Cognitive Radio MultipleXer - it is the first smart wireless system to automatically and continuously adapt to its surroundings in real time. CRMX was specifically developed to meet the demand for reliable, easy to use, and cost effective wireless lighting controls.


Building on the phenomenal success of CRMXchip, LumenRadio offers TiMo – a next generation wireless DMX/RDM module designed for high volume manufacturing. TiMo is small on form factor but huge on functionality - featuring all of the same capabilities as our classic CRMX OEM modules in a package measuring just 33.5mm x 18.5mm.

TiMo is fully compliant with the ETSI EN 300 328 v2.2.2 as well as fully FCC certified with a modular approval to 250mW – the highest allowed output power of any manufacturer within the industry thanks to LumenRadio's unique CRMX technology.

CRMX TiMo is fully compatible with CRMX transmitters running both CRMX2 and CRMX Classic, as well as transmitters from Wireless Solution running in G3, G4, G4S or G5 2.4GHz mode, enabling a single wireless component to maximize compatibility within fixtures. Manufacturers can add TiMo to their products easily with full OrCAD, Allegro and DXF symbol libraries available to simply drop onto existing layouts.
