NT925OCA Off Course Alarm

NT925OCA / 1 is primarily intended for use as an independently referenced course monitor which, when installed as an independent system or in conjunction with an appropriate Navitron Autopilot system, renders the entire configuration compliant with all articles of IMO Resolution A.342(ix).
Dual Heading input ports are standard and can be connected to accept magnetic information derived from a Navitron heading sensor coil attached above or below an existing ships compass and/ or a range of NMEA 0183 heading sentences derived from proprietary sources such as GPS compasses and Gyro's etc. Whilst only one heading input is essential, dual inputs will provide a back up system where either input maybe chosen as the primary or secondary heading reference.
Standard features include installation programmable Deviation and Variation correction, NMEA 0183 and Step by Step (installation Programmable 3, 6,12 and 24 step/degree) heading outputs for use by proprietary radars etc.
NT925OCA / 2 is designed for use as an independently referenced Off Course Alarm but includes a Course Comparator Alarm which may be enabled or disabled during installation as required.
Unlike the heading sensor coil and single NMEA input associated with the NT925OCA / 1, the NT925OCA / 2 features dual NMEA 0183 heading input ports. Only one input is required for Off Course Alarm operation whilst dual inputs are essential for the additional Course Comparator function which continuously monitors and compares the two sets of NMEA data received. In the event of excessive differences between the data received (trip level installation programmable 1-20") the alarm is activated.
A Step by Step (installation programmable 3, 6,12 and 24 step/degree) output facility is standard.
