It combines a precision 3-axis solid-state magnetometer and a rugged 2-axis electrolytic tilt sensor to provide accurate heading and tilt measurements over a wide range of environmental conditions. The firmware and signal processing algorithms have been refined and improved over three prior generations of compasses to deliver the ultimate in performance from the available sensor data. A key advantage of the ECS is its quick-connect, external serial interface. While the compass is inplace, and without disconnecting system wiring, a serial cable or available USB cable can be temporarily connected via the RJ12-style modular receptacle. This allows easy access during installation for calibration and tuning. It also provides a valuable diagnostic port and can be used for an auxiliary read-out when needed. In situations where a fixed installation is not desirable, the RJ12 connection can be used exclusively. Among the host of user definable parameters is the selection of NMEA output data Attitude Display in PC Software and update rate; operating mode as continuous or query-only; and angle data in degrees, mils, radians, or 16-bit integer (65536 counts per revolution). Compensation for both hard and soft iron influences is built-in. Jewell Instruments offers a development kit that includes the compass, cable, and software. The ECS is covered by a full one-year replacement warranty. Jewell Instruments LLC 850 Perimeter Road, Manchester, NH 03103 [email protected] • www.jewellinstruments.com • Tel (800) 227-5955
