3 Conductor

Connector Wiring: 3-Conductor

The purpose of this page is to share common wiring schemes for 3-conductor systems. As additional systems are added, please include them in a form in which others can benefit.

3C Water-proof connectors

Water-proof connectors are available from Ray Wu, but they can also be purchased from US-based resellers (ask around for names). The following wiring scheme is offered as a standard to connect smart strings to a smart string controller (SSC). The original color assignments are taken from the wire colors used by an earlier 3-color pigtail -- which matched the colors used by the smart string pixels. Later 3-conductor pigtails use a different set of colors and must be converted to match the SAME pinouts used by the first generation. If DLA members use a common wiring standard, then old and new SSCs will be able to work with various string types. Further, kits assembled by other DLA members will be able to interoperate with kits from other DLA members. The chart below serves as a way to convert between old and new connector wire colors so that old and new connectors can be compatible as you add new devices to your display.
