Cable-free DMX links for the spans where running copper is impractical: transceivers, dongles and battery-powered units from Chauvet, ADJ, LEDJ and City Theatrical covering the W-DMX and CRMX ecosystems on the 2.4GHz band.

Protocol compatibility is the first check. W-DMX and CRMX are separate systems, so a transmitter and receiver must speak the same one; units like the Chauvet Professional Micro T-1 TRX G6 are built to work with both W-DMX and CRMX fixtures, which makes them safer buys for mixed hire stock. Battery-powered transceivers such as the WELL Connect suit uplighter packages and temporary positions with no local power, while the City Theatrical Multiverse SHoW Baby remains a favourite for quick point-to-point links. Think about the RF environment too: a festival site or conference venue saturated with Wi-Fi shares the same 2.4GHz spectrum, so mount units with line of sight, keep hop distances sensible, and test before doors rather than during the show. ADJ’s Aria X2 system adds a gateway and rackmount options for tidier permanent setups.

Wireless is a bridge, not a replacement for cable on critical paths; most designers keep the main control runs on copper and use wireless for the awkward last hops.
