A5040 IP68 GYRO COMPASS FEATURES • IP68 - see note 1 • NMEA-0183 • Furuno / SPI • 2 Axis Tilt compensation to 45° • Solid-state yaw sensor • 8-30 V Supply • Rich command set • Rate-of-Turn sentence (HFROT/HEROT) • Auto calibration button • Set zero button APPLICATIONS • Autopilots • Marine and Vehicle Compass • Radar “North up” • AIS • Off-Course Alarms systems Heading output is derived by integrating the rate output from a MEMS yaw accelerometer or ‘gyro’ which is drift-corrected by a fluxgate magnetometer with pitch and roll compensation up to 45°. ABSOLUTE MAXIMUM RATINGS After auto-calibration with original error not more than 20degrees In addition to error at 0 degrees of tilt ORDER INFORMATION PART

ELECTRICAL CHARACTERISTICS AT 20°C PARAMETER NMEA-0183 OUTPUT FORMAT (software subject to change) The output from the compass is a standard NMEA-0183 sentence which can be configured to be in one of several standard forms: Eg: $HCHDG,hhh.h,,,,*ss<CR><LF> or $HCHDT,hhh.h,T<CR><LF> where hhh.h represents the magnetic heading with one decimal place of precision, i.e: 000.0 to 359.9 degrees. The two HEX digits, ss, are a checksum. Serial output is RS422, 4800 Baud, 8 data bits, 1 stop bit, no parity. An option is to include $HFROT,zxxx.x,A*cc<CR><LF> (or ...HEROT...) The compass may be...
