Product Details

Secure DMX Cable Elimination and Wireless Data Distribution

The DMXio-HG is a reliable, easy to use and secure 2.4GHz wireless transceiver with an external antenna that is both a receiver and a transmitter. Working together, a  pair of DMXio-HG units will eliminate the need for endless DMX cables for lighting control. Using RC4 One Touch, control is as easy as the push of a button, and the DMXio-HG 2dBi omnidirectional antenna works reliably up to 200’ (60m) – 300′ (91m) or more inside all types of performance spaces. In general, line-of-sight is not required for RC4Magic products, but dense objects between units — like concrete walls — will attenuate the radio signal and reduce the available range.

RC4 Magic DMXio

Various settings are available, including transmit/receive mode, DMX termination on/off, and channel range limits. Buttons are recessed and tamper-proof. The distance from console to stage is rarely more than 00 feet, well within the 200-foot range of RC4Magic.

The DMXio-HG is a transmitter for all RC4 Magic 2.4GHz wireless dimmers, including the popular DMX2dim, DMX4dim, and DMX4dim-500. When in transmitter mode, the DMXio-HG decodes the incoming DMX universe, encodes and encrypts it, and then broadcasts it using Direct Sequence Spread Spectrum (DSSS) digital radio.  Unlike wired DMX, the broadcast signal includes error checking and correction codes and is not affected by minor interruptions and interference.

As a receiver, the DMXio-HG decodes the rf signal from the transmitter, rebuilds the DMX universe, and regenerates a standard DMX signal with the same number of channels and the same packet rate as the data going into the transmitter. Numerous DMXio-HG units in receive mode can be used simultaneously, taking the place of splitters, isolators, and distribution boxes, providing superior electrical isolation while eliminating unsightly, cumbersome wiring.

All RC4 products arrive programmed with three unique, super secure System IDs. RC4 IDs serve as system identifiers and encryption keys, ensuring interference-free operation anywhere, anytime, worldwide. Every RC4 user and project has their own unique, protected ID. A common public ID is also provided, allowing multiple RC4Magic systems to be combined and used as one large system at any time.

Power for the DMXio-HG can come from the supplied wall transformer, from external batteries, or (optionally via internal jumpers) from XLR pins 4 and 5. A small pack of 6 AA batteries can be used for portable operation with, for example, a DMXter, Pocket Console, or other battery-powered DMX signal source.

The RC4Magic Series 3 DMXio-HG plus an RC4 CodeLoader cable can be used as a dongle with RC4MagicPC software.

Wireless users in the USA, Canada, Brazil, Australia and New Zealand who are in a crowded wireless environment, please consider the RC4Magic-900SX DMXio-HG.
