The AHRS should not be exposed to large magnetic fields. This could
permanently magnetize internal components of the AHRS and degrade its
magnetic heading accuracy.

Package Contents
In addition to your DMU sensor product you should have:
•
1 CD with GyroView Software
GyroView will allow you to immediately view the outputs of the
AHRS on a PC running Microsoft® Windows™. You can also
download this software from Crossbow’s web site at
http://www.xbow.com.
•
1 Digital Signal Cable.
This links the DMU directly to a serial port. Only the transmit,
receive, power, and ground channels are used. The analog outputs
are not connected.
•
1 DMU Calibration Sheet
The Digital Calibration Sheets contains the custom offset and
sensitivity information for your AHRS. The calibration sheet is
not needed for normal operation as the AHRS has an internal
EEPROM to store its calibration data. However, this information
is useful when developing your own software to correctly scale the
output data. Save this page!
•
1 DMU Data Sheet
This contains valuable digital interface information including data
packet formats and conversion factors.
