Intelligent Steering Technology (IST) adapts continuously to sea conditions and vessel speed, while the AUTO-SETUP routine handles drive detection, rudder response timing, and compass calibration automatically. The sunlight-readable 5.7\" color LCD switches to a red night palette to preserve operator night vision, and NMEA 2000, Ethernet, and NMEA 0183 connectivity keeps the system integrated with existing onboard instruments.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eIST (Intelligent Steering Technology) delivers superior vessel steering across varying conditions\u003c\/li\u003e\n\u003cli\u003eADAPTIVE steering automatically adjusts to sea state and vessel speed changes\u003c\/li\u003e\n\u003cli\u003eAUTO-SETUP routine handles drive detection, rudder response time, and compass detection and calibration\u003c\/li\u003e\n\u003cli\u003eNMEA 2000, Ethernet, and NMEA 0183 input\/output interface\u003c\/li\u003e\n\u003cli\u003eConfigurable for fishing vessels, offshore boats, workboats, towboats, and yachts\u003c\/li\u003e\n\u003cli\u003eWORK Mode optimized for fishing boats, towboats, and workboats\u003c\/li\u003e\n\u003cli\u003ePRC (Proportional Rate Control) delivers smooth, gentle steering response\u003c\/li\u003e\n\u003cli\u003eMulti-station capability with security station lock\u003c\/li\u003e\n\u003cli\u003eSunlight-viewable 5.7\" color LCD with 9-level backlight and red night palette\u003c\/li\u003e\n\u003cli\u003eNAV Mode provides adaptive, precise track steering\u003c\/li\u003e\n\u003cli\u003eALC (Automatic Leeway Compensation) corrects for drift, tide, and wind\u003c\/li\u003e\n\u003cli\u003eFully compatible with onboard instruments and existing steering systems\u003c\/li\u003e\n\u003cli\u003eOptional Z-Drive interface supports 360° azimuth drive\u003c\/li\u003e\n\u003cli\u003eOptional automatic bow-thruster control for hands-free Sabiki fishing or station keeping\u003c\/li\u003e\n\u003cli\u003eMulti-language support: English, Chinese, French, German, Norwegian, Spanish, Italian, Vietnamese, and more\u003c\/li\u003e\n\u003cli\u003eFlush mount kit included; optional swivel mount bracket available\u003c\/li\u003e\n\u003cli\u003eIP67 waterproof rating on control head, TS4, NF4, and WS4 components\u003c\/li\u003e\n\u003cli\u003eRoHS and CE compliant for EMI and RFI immunity\u003c\/li\u003e\n\u003cli\u003ePre-defined parameter sets for full\/semi-displacement hulls, planing hulls, stern drives, and sailboats\u003c\/li\u003e\n\u003cli\u003eMultiple steering parameter sets for fast cruise, slow cruise, and work modes\u003c\/li\u003e\n\u003cli\u003eCourse knob with mechanical detent for simple, tactile adjustments\u003c\/li\u003e\n\u003cli\u003eAutomatic trim function\u003c\/li\u003e\n\u003cli\u003eAdjustable yaw, turn rate, and rudder settings\u003c\/li\u003e\n\u003cli\u003ePORT and STBD dodge buttons for collision avoidance\u003c\/li\u003e\n\u003cli\u003eAnalog rudder angle indicator output supports up to 4 stations\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eOperating Voltage: 10–30 VDC\u003c\/li\u003e\n\u003cli\u003ePower Consumption: 0.5 A average, 3 A peak (reduced with low backlight setting)\u003c\/li\u003e\n\u003cli\u003eDrive Output: 20 A\u003c\/li\u003e\n\u003cli\u003eNetwork: NMEA 2000 and Ethernet\u003c\/li\u003e\n\u003cli\u003eNavigational Interface: NMEA 0183 input\/output\u003c\/li\u003e\n\u003cli\u003eNMEA 0183 Output: Heading (10x per second), Autopilot Status (1x per second)\u003c\/li\u003e\n\u003cli\u003eHeading Reference: Fluxgate, magnetic compass, NMEA compass, or satellite compass\u003c\/li\u003e\n\u003cli\u003eCourse Resolution: 1°\u003c\/li\u003e\n\u003cli\u003eCourse Detection: 0.5°\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SI-TEX","offers":[{"title":"Default Title","offer_id":54530194604307,"sku":"SIT-SP38-18","price":5879.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0986\/9718\/3507\/files\/78776XL.jpg?v=1785972561","url":"https:\/\/www.elliottstackleandrigging.com\/products\/si-tex-sp38-18-autopilot-core-pack-including-compact-gps-compass-rotaryfeedback-no-pump-sp38-18","provider":"Elliott's Tackle \u0026 Rigging","version":"1.0","type":"link"}
