TracVision G4 Technical Manual
Compass Calibration
Function: calibrates the sensor module
Command: =CALGYRO
Response: system initializes rate bias and calibrates the
azimuth and elevation axis gyros
H.6 RF Board Commands
Serial Communications, Status/Polarization Report, Tone Changes
Function: starts serial communications, reports status and
polarization/tone changes
Command: @S
Response: S,s,p,b,m <cr> every 5 seconds until ><cr>is
returned from system software
Where: s = satellite (A = primary, B = secondary)
p = polarization (V = vertical, H = horizontal,
R = right, L = left, X = no LNB power)
b = band (H = high band, L = low band,
U = USA)
m = mode (V = valid, I = invalid)*
* The Mode bit is used to evaluate the Satellite, Polarization and Band
combination vs. the Frequency/Symbol Rate/FEC currently in RAM. This
bit will be set to invalid if the Frequency for the selected combination is
set to 0x0000; otherwise it will be set to valid. For example the Mode bit
will be set to invalid when the frequency is set to 00000 to indicate that
there is not a frequency to track for the LNB tone and voltage setting.
