New ▼ CRM500/CRM510 REMOTE MAGNETIC SENSING UNITS ▼ FAA Certified Remote Magnetometer (CRM500GA) ▼ High Resolution Flux Gate Sensors ▼ Compatible with Crossbow FAA Certified AHRS500GA ▼ For use in DO160D Wing or Tail Mount environments ▼ DO178B Software CRM500GA/CRM510GA Applications ▼ General Aviation ▼ Unmanned Aerial Vehicles The CRM Series remote magnetometers employ an RS-422 serial digital data bus with a Baud rate of 38,400. They are configured to operate in an auto send mode so that data is automatically and continuously sent after power up. Output data is transferred in a compact binary format and includes three axes of magnetic field along with built-in-test status. The CRM Series remote magnetometers are high performance three-axis strap down magnetic field measurement systems. They are designed as a local magnetic field reference for use with high performance Attitude & Heading Reference Systems such as the AHRS500GA/AHRS510GA. ▼ magnetometers The CRM Series remote magnetometers are easy to install and include micro-machined accelerometers to allow for automated alignment with the AHRS500GA/ AHRS510GA during installation. The CRM500/510 remote magnetometers come with a User’s Manual and Installation Manual offering helpful hints on programming, installation, and product information. Crossbow’s MagAlign software is also included to assist users with Hard and Soft Iron magnetometer alignment. 2.62 3 x .156 Ø 2.900 3 x 10˚ 3 x 10˚ CABLE WITH CONNECTOR 2x 4.000 2 x 120˚ 4x Ø .180 ±.005 THRU Ø 3.370 2x .38 2x .185 2x 2.000 4.65 .310 2.03 1.54 1.65 .58 2.22 2.375 1.050 CRM500GA Dimensions ▼ 46 4.37 CRM510GA Dimensions Document Part Number: 6020-0085-02 Rev A c ro s s b o w t e c h n o l o g y, i n c ▼ 4145 n. first street ▼ san jose, ca 95134-2109 C CRM500GA /CRM510GA Performance Magnetic Bias (Gauss) Magnetic Range (Gauss) Linearity (% full scale) Sensor Axes Alignment to Case (°) Noise (nT/ Hz)1 Data Output Rate (Hz) Environment Operating Temperature Range (°C) RTCA/DO-160D Qualification Pin Remarks 1 2 3 4 5 6 ± 0.005 ± 0.65 ± 0.1 ± 0.2 2 >50Hz Pin 1 2 3 4 10 11 RS-422 38400 1.5 W @ 9 to 32 V 3.370 OD x 2.03 8.56 OD x 5.15 4.37 x 2.62 x 1.65 11.10 x 6.70 x 4.20 6-pin non-magnetic circular (D38999/26FA35PN) 13-pin non-magnetic circular (D38999/25NB35PN) < 0.5 < 0.5 CPU + EEPROM A/D Tri-axial Magnetometer Function DC Power In DC Power Gnd RS-422 TX+ RS-422 TXCase Ground Signal Ground CRM510GA Pin Diagram without connector without connector Shell size 9 Shell size 11 Notes 1 Limited by A/D resolution Specifications subject to change without notice Tri-axial Accelerometer DC Power In DC Power Gnd RS-422 TX+ RS-422 TXDo Not Connect Do Not Connect CRM500GA Pin Diagram -55 to +70 D2XBBB[(TEE1P)(UFF1)]XWXXXXZBABC[WWW] MA3G33XAA Electrical Communications Protocol Baud Rate Power Input Physical Size CRM500GA (in) (cm) Size CRM510GA (in) (cm) Connector CRM500GA Connector CRM510GA Weight CRM500GA (lbs) Weight CRM510GA (lbs) Function RS-422 Calibration Algorithm Temp Sensor CRM Block Diagram Byte Description 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 Header (0xAA) Header (0x55) X Acceleration (MSB) X Acceleration (LSB) Y Acceleration (MSB) Y Acceleration (LSB) Z Acceleration (MSB) Z Acceleration (LSB) X Magnetic Field (MSB) X Magnetic Field (LSB) Y Magnetic Field (MSB) Y Magnetic Field (LSB) Z Magnetic Field (MSB) Z Magnetic Field (LSB) Model (MSB) Model (LSB) Built-In-Test (MSB) Built-In-Test (LSB) Checksum (MSB) Checksum (LSB) ▼ magnetometers Specifications CRM Series Digital Output Data Format CRM510GA Ordering Information Model Description CRM500GA-200 CRM510GA-200 Strapdown 3-Axis Fluxgate Magnetometer Strapdown 3-Axis Fluxgate Magnetometer Document Part Number: 6020-0085-02 Rev A phone: 408.965.3300 ▼ fax: 408.324.4840 ▼ e-mail: [email protected] ▼ web: www.xbow.com ▼ 47
