Wireless DMX

Wireless DMX is becoming more popular due to the complexities sometimes found when installing colour change luminaires in areas which are difficult to run control cables, or external applications where larger distances are involved.

All the wireless DMX transceivers on the market use a proprietary signal, meaning only the same manufacturers' products will work with each other, you can not mix and match between transmitters and receivers.

The distance of a wireless DMX connection can be very large, with a recent experiment successfully transmitting signals from England to France across the English Channel. Usually, wireless DMX can transmit around 300m. The actual distance depends on physical obstructions, for instance, the construction material of a wall.

Wireless DMX can be found in theatrical environments where lights need to be controlled on, for example, a moving piece of scenery. In such a scenario, a control cable can not be run between the controller and the lighting fixture. Another example would be when time is limited so time spent installing cables is not available. In architectural projects it can be used to transmit between buildings or around historic sites where new cables can not be installed.

To set up a wireless DMX system you need a transmitter and at least one receiver. The transmitter connects to the output of the controller and it trasmits the DMX signal. The receiver converts the radio frequency signal back to a DMX signal which can then be connected to a DMX input on a DMX device. Any number of receivers can be used with one transmitter allowing for a virtually limitless system to be built.

Apollo Lighting can specify and supply wireless DMX solutions on a project by project basis. This ensures compatibility and functionality of the system as a whole.
