Entering User-defined Satellite Data
Once the link between the PC and the TracVision L3/S3 is
established as described in Section 2.5, “Selecting the Active
Satellite,” you need 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)
