An external interface unit, the WeCan® Electronic Control Module (ECM), communicates all lightbar operating functions via a 2 conductor, 20 gauge cable. This small cable provides easier overall wiring and lightbar installation. Up to 18 different programmed warning configurations can be operated using customer supplied switching to each of 18 input wires to the ECM. Lightbars can be pre-programmed with customer default programs prior to shipping.
Lightbars that are supplied without customer specified programs come with a default program.

All functions are programmed easily by a computer via simple “pick and click or drag” screens. Windows® XP SP2, Vista, 7, 8 or later operating system required. USB input to the ECM from PC or laptop makes programming easy to each of eighteen input wires to the ECM. Lightbars can be pre-programmed with customer default programs prior to shipping.
