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.

CRMX TimoTwo

Building on the phenomenal success of CRMXchip and TiMo, LumenRadio offers TimoTwo – a next generation wireless DMX/RDM module designed for high volume manufacturing. TimoTwo keeps the small form factor as TiMo (33.5mm x 18.5mm), with pin-compatibility, offering even more features.

TimoTwo is fully compliant with the ETSI EN 300 328 (v2.1.1) revision as well as fully FCC certified with a modular approval to 100mW.

As with all LumenRadio receivers, TimoTwo is fully compatible with all CRMX transmitters, enabling a single wireless component to maximise compatibility within fixtures. Manufacturers can add TimoTwo to their products easily with full OrCAD, Allegro and DXF symbol libraries available to simply drop onto existing layouts.
