SDM-650B Satellite Modem Remote Control Operation
Rev. 6 B–7
B.1.3.7 Modulator Rate
The modulator has four symbol rate filters. Each filter is for a specific symbol rate. The
data rate and coder rate for each filter must be established upon initial modulator
installation, and when circumstances indicate the need to do so.
Filters are designated as A, B, C, and D. If a filter is not physically present in the system,
it may be assigned “N/A” (not assigned).
Additionally, filters which are factory programmed may not be remotely programmed,
and will return the “error 5” message when a programming command is issued.
Notes: For the variable rate modulator option:
1. Modulators with the variable rate option installed may have four preprogrammed
rates available by using the filter rate assignment commands. These rates are
selected using the standard “SMRx_” commands.
2. Modems that have the variable rate option installed will also respond to the
special “SMRV_” command.
B.1.3.7.1 Modulator Filter Rate Assignment
Command: <add/AMRx_nnn_mmmm.m”cr”
Response: >add/AMRx_nnn_mmmm.m”cr””lf”]
Status Only: <add/AMRx_”cr”
Response: >add/AMRx_nnn_mmmm.m”cr””lf”]
Where:
x = A, B, C, or D (Filter designator).
nnn = 1/2, 3/4, 7/8, or BP12 (Coder rate).
mmmm.m = 9.6 to 4080.0 (Data rate).
Note: The parameters “nnn_mmmm.m” may be replaced by “N/A” to indicate “no
assignment.”
Example:
Command: <add/AMRx_N/A”cr”
Response: >add/AMRx_N/A”cr””lf”]
