DMX-512 LED Controller with LED Display

Step 4 LED Display and Buttons, Wiring

This controller has an external 3 digit LED display and 2 buttons to set the modes and address.

LED Display PCB:

• Real simple just put it together as shown in the images.
• 2 buttons and the LED display

The LED display and buttons are wired to the main controller PCB by some ribbon cable. This enables the display and buttons to be mounted away from the main controller.

Wiring:

• Using a razor blade, start by splitting the cable about 0.5" - 1" long, both ends
• Strip all 1/8" of insulation of each wire, both ends
• One wire at a time, carefully solder them one after the next to the controller.
• Lay it out flat and place the LED display on the un-soldered end, note where the wires should be soldered. The boards are connected to each other the same way they would be if they were lined up next to each other with the holes lining up, face up. See image.
