CANdrive offers a cost-effective instrument solution for modern electronic engines.

CANdrive modules read engine ECU CAN bus/J1939 data, drive standard electric panel gauges and provide LED indication of status and faults. CANdrive has three dedicated outputs for tachometer, oil pressure and coolant temperature gages, with DIP switch selectable compatibility for Murphy, VDO or Datcon gauges. For volume orders, the outputs can be custom configured for other gage types, lamps, relays or remote signaling.
