Raymarine Pathfinder GyroPlus 2 Owner's Handbook Manual

Appendix: Connecting to Autopilots 27Connecting to AutopilotsAppendix: Connecting to AutopilotsThe information in this Appendix explains how to connect theGyroPlus 2 unit to the following Raymarine autopilot systems:• connecting to T150 or T400 course computers (Section A.1)• integrating with other Raymarine autopilots (Section A.2)• ST4000+ or ST5000+ autopilot (see page 30)• T100 or T300 course computer (see page 31)A.1 Connecting to T150 or T400 course computersConnecting the GyroPlus 2 unit to a T150/T400 upgrades the coursecomputer so it has the same functions as a 150G/400G:• ‘AST’ (Advanced Steering Technology) is enabled, providingenhanced course keeping and FastTrim• AutoLearn is enabled, providing automatic steering calibration whenused with a ST6001+ or ST7001+ autopilot control unit• the course computer NMEA 1 port will transmit 10 Hz fast heading,suitable for MARPA and radar/chart overlay on Pathfinder Plus unitsConnecting to T150/T400 course computerTo connect the GyroPlus 2 unit to a T150/T400:• leave the autopilot fluxgate compass connected to the T150/T400• power the GyroPlus 2 unit via SeaTalk• connect its RATE OUTPUT to RATE GYRO inputs on the T150/T400Connecting to T150/T400 course computer and Pathfinder PlusTo connect the GyroPlus 2 unit to a T150/T400 course computer and alsoa Pathfinder Plus:• leave the autopilot fluxgate compass connected to the T150/T400• connect the RATE OUTPUT on the GyroPlus 2 unit to the RATEGYRO inputs on the T150/T400• power the GyroPlus 2 unit from both SeaTalk and the distributionpanel:• provide power from SeaTalk so the GyroPlus 2 unit receivespower when the course computer is powered up but the Path-finder is off• provide power from the same switch as the Pathfinder Plus so theGyroPlus 2 unit receives power when the Pathfinder is poweredup but the course computer is off• connect the NMEA 1 outputs on the course computer to the NMEAinputs on the Pathfinder Plus
