The SI-TEX SP38-4 Autopilot Core Pack delivers Intelligent Steering Technology (IST) in a vessel-agnostic platform built for commercial and recreational use alike. This core pack includes the rotary feedback unit but does not include a compass or hydraulic pump. Auto-Setup streamlines commissioning by handling drive detection, rudder response timing, and compass calibration automatically, while Adaptive steering continuously adjusts to changing sea states and vessel speeds. A sunlight-readable 5.7" color LCD with nine backlight levels and a red night palette keeps the helm functional around the clock. NMEA 2000, Ethernet, and NMEA 0183 connectivity integrates the system with existing onboard instruments, and multi-station support with security lock lets you manage control from multiple positions.
