G.5 RF Board Commands
Serial Communications, Status/Polarization Report, Tone Changes
Function: start serial communications, reports status &
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, x = No
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 & 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.
Report RF Tracking Parameters
Function: reports all RF tracking parameters for primary &
secondary satellites*
Command: @SATCONFIG
Response: F,x,fffff,S,C,ID,P,B,D <cr>
Where: x = Satellite (a = Primary, b = Secondary)
fffff = Frequency in MHz (00000 and 10700 to
S = Symbol rate in Mbit/sec (1000 to 29999)
C = FEC code rate (valid rates = 12, 23, 34, 56,
ID = Satellite Network ID in hexidecimal format
P = LNB Polarization (v = Vertical, h = Horizontal)
B = the LNB down conversion frequency (l = low,
D = decoding type (0 = test, 1 = DSS-A, 2 = DSS-B,
* This command dumps all eight combinations of the Satellite/Freq/Sym/
FEC/ID/POL/Band/Decode currently stored in RAM.

(valid range = 0x0000 to 0xffff hex)
h = high, u = USA)
