where, <CR> is a carriage return.
These commands put the CXM543 in text (as opposed to binary) mode and
angle (as opposed to vector) mode. Set the transmission speed to a slow
value (about once per sec.) by issuing the command:
F1 <CR>
Next, put the CXM543 in autosend data mode by issuing the command:
A <CR>
The CXM543 will commence to send data in the format
<Roll> <Pitch> <Azimuth> <Total gravity field> <Total magnetic field>
Verify that the roll angle is near 0°, pitch is near 90° and azimuth is near 0°.
Verify that the total gravity field is near 1.00 and the total magnetic field is
between 0.4 and .6. The magnetic field amplitude (in Gauss) varies around
the world between these values. Next, orient the CXM543 in various
different known orientations and check the accuracy of the measured data.
Stop the data transmission and change to sensor (vector) output mode by
issuing the commands
S <CR>
M = V
A <CR>
The sensor data is transmitted with the format:
<AX> <AY> <AZ> <MX> <MY> <MX>
where, AX is the X accelerometer output, MX is the X magnetometer
output, etc. All accelerometer outputs should range b1 (down) and
–1 (up). The magnetometer outputs should range from about –0.45 Gauss
to +0.45 Gauss.
