WARNING
Do not reverse the power leads!
Applying the wrong power to the AHRS
can damage the unit; Crossbow Technology is not responsible for resulting
damage to the unit.

NOTE
The analog outputs from the AHRS are unconnected in this cable.

Setup GyroView
With the AHRS connected to your PC serial port and powered, open the
GyroView software.
1. GyroView should automatically detect the AHRS and display the
serial number and firmware version if it is connected.
2. If GyroView does not connect, check that you have the correct
COM port selected. You find this under the “DMU” menu.
3. Select the type of display you want under the menu item
“Windows”. Graph displays a real time graph of all the AHRS
data; FFT displays a fast-fourier transform of the data; Navigation
shows an artificial horizon display.
4. You can log data to a file by entering a data file name. You can
select the rate at which data is saved to disk.
5. If the status indicator says, “Connected”, you’re ready to go. If
the status indicator doesn’t say connected, check the connections
between the AHRS and the computer; check the power; check the
serial COM port assignment on your computer.
2.4
Take Measurements
Once you have configured GyroView to work with your AHRS, pick what
kind of measurement you wish to see. “Graph” will show you the output
you choose as a strip -chart type graph of v alue vs. time. “FFT” will show
you a real-time fast Fourier transform of the output you choose.
“Navigation” will show an artificial horizon and the stabilized pitch and roll
output of the AHRS.
Let the AHRS warm up for 30 - 60 seconds when first turned on. This
allows the Kalman filter to estimate the rate sensor biases. Now you’re
ready to use the AHRS!
