SDM-2020 Satellite Demodulator Remote Control Operation
Rev. 3 B–15
Current
Sweep
Value Command:
Response: <add/CSV_'cr'
>add/CSV_'cr'
CSV_xsnnnnnn'cr'
CD_yyy'cr''lf'] Where:
x = < or > (data modifier to indicate that the sweep
offset value is less than or greater than the returned
value).
s = + or - (sweep offset from center).
nnnnnn =
For L-Band only: 0 to 500000
For 70/140 MHz only: 0 to 30000
yyy = OK or FLT (decoder lock status OK or FAULT).
This command returns the current sweep offset value.
Notes:
1. The 'x' (< or >) parameter is only returned if the
level has exceeded the computational resolution
of the system.
2. 'No Data' is returned if the level cannot be
calculated.
3. 'Sampling' is returned if not enough data is
currently available to calculate the level.

Monitor
Status Command:
Response: <add/CMS_'cr'
>add/CMS_nnnn'cr''lf'] Where: nnnn = 0 to 1000 mA in 1 mA steps.
Note: This command applies to L-Band RF modems.
B.8 Stored Faults
Information on stored faults is returned when requested. If no stored fault exists for a
given fault number, the words “NO Fault” will be returned, instead of the normal
time/date status information.
The following symbols are commonly used to define the stored faults status commands:
•
# Fault number (0 to 9). “0” is the first fault stored.
•
hh Hours in 24-hr. format.
•
mm Minutes.
•
ss Seconds.
•
MM Month.
•
DD Day.
•
YYYY Year
