Ametek Dixson has added a light bar message center to its modular Next Generation Instrumentation (NGI) system. The LMC is designed to receive messages from the vehicle data bus and signals from discrete switches and analog sensors throughout the vehicle; the LMC then processes the data to drive telltales and gauge pointers, display vehicle information or broadcast messages on the vehicle data bus.
The LMC features SAE J1587/1939 (CAN) data bus communication; automatic self-test on each power-up; 11 switched inputs and seven analog inputs; two switched outputs; an audible warning device; push-button, selectable displays and test functions; selectable primary display screens; backlight control for LCD display and NGI gauges; and 12- or 24-volt operation.
The amber backlit LCD contains two 20-character lines. Two switches with tactile feedback select and display trip information, fuel usage and service data, plus a number of diagnostic screens. The LMC also displays fault codes and warning messages in real time, Ametek Dixson says.
The LMC can drive up to 12NGI gauges and contains 18 telltales, each illuminated by red, green, blue, amber or white LEDs. The LMC and all attached NGI gauges can be tested using the switches. The LMC meets all SAE J1455 and J1113 requirements for vehicular instrumentation, according to the company, and was developed to withstand harsh conditions typical of off-road environments.
