Entering User-defined Satellite Data
Once the link between the PC and the TracVision C3 is
established as described in Section 2.5, “Selecting the Active
Satellite,” it is necessary to provide initial longitude data
regarding the user-defined satellite. To do so, enter the
SATCONFIG parser command via PC as follows:
Command: SATCONFIG,USERX,YYY,Z,D,L<cr>
(<cr> indicates a carriage return/ENTER key)
Where: X = 1 or 2 (satellite alternative)
YYY = longitude (0-180)
Z = E (East) or W (West)
D = decoding type (0 = test, 1 = DSS-A,
2 = DSS-B, 3 = DVB)
L = LNB polarization (C = circular, L = linear)
Function: configures one of the user-configurable satellites
with the longitude provided
Response: if valid entry, echoes the input data
if invalid entry, returns error message
After entering the SATCONFIG command, you must turn on the
DEBUG mode by typing
@DEBUGON. Following the entry of
the SATCONFIG and DEBUGON commands, enter the satellite
transponder information via PC as follows:
Command: @SATCONFIG,X,N,F,S,C,ID,P,B,D<cr>
Where: @SATCONFIG = directs data to the RF Board
X = satellite location A or B
N = satellite table # (98 & 99 are slots for user-
configured satellites)
F = frequency in MHz (either 00000 or a range from
10700 - 12700)
S = the satellite transponder symbol rate in
Mbit/second (01000 - 29999)
C = the FEC code (e.g., 12, 23, 34, 56, 67, 78)
ID = the satellite network ID in hexidecimal format
(0x####)
P = the LNB polarization (v = vertical,
h = horizontal, r = right, l = left)
B = the LNB down conversion frequency (l = low,
h = high, u = USA)
D = decoding type (0 = test, 1 = DSS-A,
2 = DSS-B, 3 = DVB)
