Remote Commands and Error Codes
CAS
Current Active
Status
Config (V)
0 = all; 1 = primary
2 = secondary; 3 = ternary
0
Sets the data path to which a status query
command will be issued.
CD
Control Data Mode
Config (NV)
1 = ignore
2 = respond
1
Sets the CM601 to monitor and respond to, or
ignore, DCE-DTE data control signals.
CE
Channel Error Rate
Monitor
?
—
Queries the channel error rate only if the
demodulator is operating with FEC decoding
enabled; if CE is issued when the CM601 is not
locked to a receive carrier, or if the CM601 is
operating uncoded, an ER 4 error response
message appears; return values format is mn
(representing m x 10-n).
CF
Clear Fault Log
Faults (V)
— = clear
0 = clear
—
Clears the fault log and current fault lists.
CFG
Card Configuration
Monitor
?
—
Displays CM601 installed cards; responses
include the slot number and a code indicating
the type of card installed in the slot.
CLP
Clear Path
Config (V)
0 = clear
0
Clears all data paths; same affect as issuing a
0 parameter with each of the transmit and
receive data path commands.
CPC
Configuration Path
Control
Config (V)
1 = enable
1
Enables the configuration path control function;
when CPC is issued, autoconfiguration default
settings are reestablished.
DAY
Internal Date
Config (NV)
MoDaYr:
Mo = 01 to 12
Da = 01 to 31
Yr = 00 to 99
0 = clock off
—
Sets the CM601 internal real-time date; real-
time date is expressed in two-digit format; time
is factory set to U.S.A. Pacific standard time; no
default; IN 9346 or INF 9346 does not reset
value in NV memory.
DB
Doppler Buffer Fill
Level
Monitor
?
—
Displays the number of data bits currently in the
data buffer.
DBB
Doppler Buffer Size
Config (NV)
64 to 8192
8192
Sets the size of the data buffer in bits; invalid
entries are rounded up to next valid size. To set
the data buffer by entering the buffer length in
milliseconds, use the DBD command.
DBD
Doppler Buffer
Delay
Config (NV)
1 to 1000
853
Sets the buffer length in milliseconds
throughout the entire buffer; the buffer normally
runs at 50 percent full, so the delay through the
buffer is typically half that of the entered
parameter; invalid entries are rounded up to
next valid size; autosets DBB.
DBM
Doppler Buffer
Mode
Config (NV)
0 = enable buffer
1 = enable bypass
1
Enables buffer or bypass mode; data does not
pass through Doppler buffer in bypass mode.
DBR
Doppler Buffer
Reset
Config (V)
—
—
Reset the Doppler buffer; when the buffer is
reset, the input and output pointers are set to
the half-full point (50%).
DC
Display
Configuration
Config (V)
— and 0 = modem format
1 = symbol rates format
7 = CM601 modular format
—
Sets the format in which the current CM601
configuration will be displayed; supported by
ASCII protocol only.
DCS
Doppler Clock
Select
Config (NV)
1 = user-supplied transmit timing
4 = internal clock or send timing
4
Selects the clock used to clock data out of the
Doppler buffer.
DD
Differential
Decoding On
Demodulator
Config (NV)
0 = disable
1 = enable standard, all except
QPSK uncoded
2 = enable standard/QPSK
uncoded
1
Controls differential decoding on the
demodulator.
