DMX Theatre Lighting /Disco Controller

1_463s pic

The DMX board provides the essential interface between PC and Microcontroller applications and the industry standard DMX network protocol as used in many theatre lighting and disco systems.

It has been designed as a flexible interface device to the very fast DMX512 network to allow enthusiasts to develop their own computer controller lighting and special effects with the minimum amount of electronics. The DMX board can be configured to act as a transmitter or receiver unit with the following features:
