The CXM543 determines the inclination and roll angles by using a 3-axis micro-machined accelerometer to measure the direction of earth’s gravity. The azimuth angle is determined by measuring the earth’s magnetic field using a 3-axis magnetometer subsystem. The CXM543 employs a high-speed serial digital output for transmitting data. Both RS-232 and TTL level interfaces are present. Baud rate is user selectable over the range 300 baud to 72,800 baud. The CXM543 can be configured to operate in either a command (polled) mode (where an external computer requests data) or an auto send (continuous) mode (where data is automatically sent repeatedly after phone: 408.965.3300 t fax: 408.324.4840 t power up). Output data can be set to ASCII format (ideal when using a PC) or in binary format (more suited to a microprocessor interface). The CXM543 can be configured to output either orientation angle data (roll, inclination, and azimuth) or sensor data (AX, AY, AZ, MX, MY, MZ). When used in orientation mode, the accuracy of the transmitted angles is ± 1.5° for azimuth and ±0.5° for roll and inclination. Angular resolution is better than ± 0.1°. When used as a gravity sensor, accuracy is ±15 mg and resolution is better than 1 mg. As a magnetic field sensor, the CXM543 fluxgate magnetometers have an accuracy of ±0.1µT and a resolution of ±0.005 µT. magnetometers t A Windows compatible program is available with the CXM543 to enable system configuration (e.g., baud rate, sample rate, mode, etc.), data acquisition, and display. e-mail: [email protected] t w e b : w w w. x b o w. c o m t Specifications Performance Angular Accuracy Inclination & Roll (°) Azimuth (°) Gravity (mg) Magnetic (µT) Angular Range Inclination (°) Roll (°) Azimuth (°) Gravity Range (g) Magnetic Range (µT) Linearity (% full scale) Sensor Axes Alignment to Case (°) Data Output Rate (angles mode) (Hz) Environment Operating Temperature Range (°) Data Levels Electrical Baud Rate (user selectable) Power Input Physical Size Connector CXM543 ± 0.5 ± 1.5 ± 8.5 ± 0.1 ± 90 ± 180 360 ±1 ± 100 (± 1 Gauss) ± 0.1 ± 0.5 25 0 to + 50 RS-232 and TTL 300 - 72,800 100 mA @ +7.5 to +15 VDC 2.75" W x 4.08" L x 1.125" H (7 cm x 10.4 cm x 2.9 cm) 9-pin non-magnetic “D” Specifications subject to change without notice Tri-axial Magnetometer magnetometers Temp Sensor 16-bit A/D t Tri-axial Accelerometer CPU + EEPROM RS-232 Calibration and Compassing Algorithm Regulator +15V 543 Digital Orientation/Compass Sensor Pin 2 3 5 6 7 8 9 Function RS 232 out RS 232 in Ground TTL serial out TTL serial in Configure +7.5 to +15V DC Pin Diagram Ordering Information Model t Description CXM543 c r o s s b o w t e c h n o l o g y, i n c High Speed Digital Orientation Sensor t 41 daggett drive t san jose, ca 95134-2109
