Kobelt 6503 Mighty Mariner System electronic interface

The 6503 is a microprocessor unit, acting as the central processor for the Mighty Mariner electronic control system. The interface monitors all input information from control heads and switch panels, communicates to the control heads and sonalerts, operates clutch solenoids and the throttle signal for the engine. The 6503 is programmed using dipswitches and trimpots and can incorporate up to 4 electronic control heads.

It can – monitor all input information from the control heads and their associated switch panels;
– monitors its clutch and throttle positions and the synchronizer inputs;
– controls and positions its electronic throttle and its electric clutch in accordance with the Control Head lever movement;
– communicates with the control stations through panel lights and sonalerts

The 6503 has three types of electronic throttle output available: 4-20mA, 0-5VDC and PWM (Pulse Width Modulation).
These outputs change proportionately with the station control head lever positioning.
