Using the well-established mobile telephone GSM technology in the 2.45GHz licence-free band, the W-DMX avoids many of the problems associated with ordinary wireless networking products. The products are all DMX512A and RDM ready, and the firmware can also be updated using a separate data channel, which is also used for system set up. Up to 8192 receivers can be controlled form one system, and there are four differing types of transmitter - the differences being primarily in the quantity of DMX universes that can be controlled: 1, 4, 8 or up to 16 universes (8192 channels) of DMX can be sent reliably using this system. The receivers are more use specific - the standard is small and lightweight whereas the Delux has a built in UPS for up to 8 hours of power loss and the Deluxe Outdoor is the same as the Deluxe but having IP65 rating. All systems have LCD screens and menu systems for easy navigation, and the 'Blackbox' version has no controls and is entirely 'plug 'n play' for one universe of DMX.
Ranges of up to 30km are possible (US Spec equipment only) with up to 12km in Europe, depending on conditions and antenna chosen. Various boosters, repeaters and ready-made cables are available as well as a range of antennas.
Wireless Solution W-DMX is will be at both the PLASA Show in September (Stand G40) and the LDI Show in Las Vegas in October (Booth 2412).
