Boat control panel NT925OCA

for autopilotswith alarm

The Navitron Off Course Alarm type NT925OCA is a fully independent course monitoring device which complies with the articles of IMO resolution A342 (IX). It can be installed with a single heading input obtained from a Navitron Heading Sensor Coil (type HSC2) or from a proprietary NMEA source (or both) when used as a completely independent system. However, if one of the heading data inputs is common to the heading data provided for an autopilot system (gyro data etc) the second heading input to the NT925OCA must be obtained from an independent (mag compass etc) source. 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.
