Ecumaster 4 Key CAN BUS Keyboard The Ecumaster 4 Key CAN BUS Keyboard is an ultra-compact, motorsport-grade control interface designed for drivers who require essential function control without sacrificing dashboard real estate. This 4-button keypad serves as a digital gateway to your Ecumaster PMU16 or EMU Black, consolidating multiple traditional switches into a single, high-speed CAN BUS stream. Perfect for mounting on steering wheel plates, center consoles, or door cards, the 4-key unit is IP67 rated, making it completely impervious to water, mud, and dust. Each button features independent RGB backlighting, providing immediate visual feedback for system statuses (e.g., using Green for "Pump Active" or Red for "Warning"). Like the larger models in the range, it utilizes a professional system of interchangeable laser-engraved inserts, allowing for a fully customized and professional cockpit finish. Technical Authority & Key Features Minimalist 4-Wire Installation: Radical simplification of vehicle wiring; requires only Power, Ground, CAN High, and CAN Low to operate. Full RGB Status Feedback: Buttons can be configured to display different colors (Red, Green, Orange) to represent active states, fault conditions, or standby modes. Rugged IP67 Protection: Fully sealed against environmental contaminants, ensuring 100% reliability in everything from open-wheel formula cars to off-road trophy trucks. Interchangeable Key Inserts: Includes the standard Ecumaster 15mm/24mm insert system. Easily swap icons for "Start", "Ignition", "Map", or "Fan" as your vehicle's setup evolves. Smart Logic Configuration: The behavior of each button (latching, momentary, or multi-step) is fully programmable via the Ecumaster Client software. Dual Keypad Support: When paired with an Ecumaster PMU, you can run up to two keypads on the same bus, allowing this 4-key unit to act as a secondary "satellite" controller. High Tactile Durability: Specifically engineered for use with racing gloves, these high-retention switches are rated for over 3 million cycles.
