DMX512 Control Interface
With visual configuration using a Cypress PSoC microcontroller
Published in issue 403, June 2010
The DMX512 protocol is a professional standard for controlling lighting equipment. However, truly general-purpose DMX driver interfaces are far from cheap. This circuit provides a wide variety of outputs and is based on a PSoC device that supports visual configuration. This makes it very easy to generate the desired setup.Regardless of whether you’re putting on a private party or organising a major festive event, you need the right lighting as well as the right sound to set the right mood.
* Versatile output configuration
* Visual microcontroller configuration
* Free development environment
* DMX512 input
* DMX512 output (feedthrough or repeater)
* DMX status LED
* 4-section DIP switch for configuration settings
* Temperature sensor for fan control
* Supply voltage range 13–18 V (DC) or 9–12 V (AC)
Outputs:
* 1 fan (motor) drive
* 1 DC motor drive with bidirectional rotation
* 5 configurable outputs (with separate status LED for each channel):
Open collector (with pull-up to 5 V or 10 V)
- switch, pulse or PWM mode
Hi-wide switch (10 V)
- switch, pulse, PWM, or analogue (0–10 V) mode
* 6 floating switch outputs (solid-state relay)
