M = TO
M = KO
To disable the sending of these data issue the commands:
M = TN
M = KN
If corrected data in angle and decimal mode is selected (Mode=cad) the data
output format is as follows:
Roll Pitch
Azimuth Total M Total A
CS <CR><LF>
21.73 90.05 180.01 0.45671 1.00000 3D
For corrected data in vector data in binary mode (Mode=cvb) a typical
transmission is as follows:
AX AY AZ MX MY MZ T CS EOT
FFEB01F83FOC02EC7CEA2BCC1000895A
This binary transmission is equivalent to the corrected decimal vector
previously shown above, namely:
AX AY AZ MX MY MZ T
-0.00128 +0.03076 +0.98512 +0.02282 +0.25378 +0.34216 32.0
The binary checksum is computed as follows:
FF+EB+01+F8+3F+0C+02+EC+7C+EA+2B+CC+10+00 = 689
The checksum is 89, which is the least significant byte of the sum.
When the CXM543 mode is selected to be raw, the transmitted data
represents the raw Analog to Digital (A to D) count outputs for the various
magnetometer and accelerometer sensors. The A to D’s have 16 bit
resolution, and hence, their output ranges (in decimal) from –32,768 to
+32,767. In hex the A to D outputs range as follows:
Count
Hex Output
32767
7FFF
0
0000
