This is the Compustar OP500 Feature Programmer. The OP500 does a different job from the flashing tools on this page. It doesn't load firmware. It changes how an already-installed Compustar system behaves, and it is the only way to adjust POCs (programmable output controls) and auxiliary output timing. If a customer wants their aux channel repurposed or an output timing changed, this is the tool. Features Compatible with all Compustar systems except DC2, DC3 and DCXHeavy duty silicone protective caseHardened plastic constructionBright LED display Before you order The OP500 connects through the controller's antenna cable, which is not included. It assumes the system you're programming already has one fitted. If yours doesn't, add a cable to your order using the product options above. Not sure whether your system is supported?
