Full-line of Direct Data-Bus Instruments (DDBI™) (patent pending) - gauges, tachometers and speedometers - for NEW electronic engines, in either SAE J1939 or J1708/1587 formats. Units may be connected directly to the vehicle bus network. Interconnect wiring harnesses are available.

• Direct J1939 or J1708/1587 bus connections
• Instruments work as a stand-alone solution or in parallel when interconnected
• Easy drop-in replacement for current analog gauges
• Stepper motor drivers; full-sweep (270°) gauges with Return-To-Zero(RTZ) feature
• LED backlighting (amber standard; red, green or blue optional)
• Integral LED warning lights for operator alert. Pre-set thresholds safeguard operation
• Lighted pointers for improved visibility
• Custom-engineered, "ruggedized" cases with integral sealed connectors
• Versions available with domed lenses for more streamlined look
• Fully sealed instruments with anti-fog lenses for all-weather protection
• LEDs flash when unit has no signal (to warn operator)
• Improved accuracy and consistent monitoring
• EMI/RFI & electrical system protection

• Appropriate engine/vehicle data is assumed to be available on bus network
• Non-bus functions such as fuel level, air & brake pressure integrated via A/D conversion in instrument
• Consult with factory or dealer as necessary to establish detailed product specification
