Remote Commands and Error Codes
5-9
MCS
M&C Clock Select
Config (NV)
0 = not through M&C card
1 = SMA to TTL terminated
2 = SMA to TTL unterminated
3 = 15-pin D status relay to
differential RS-442A receiver
terminated
0
Selects the interface and connector type used
on the M&C card to receive an external bit
timing clock. If value 1, 2, or 3 is selected, this
clock is routed over the CM601 backplane for
use by circuits on other boards. Currently this
command is only available when using the high
stability M&C card.
MD1 -
MD9
Modem Data
Config (V)
one or more CM601 commands
separated by semicolons, up to
120 characters
—
Used when controlling a remote modem
through an SCC option card; each modem data
commands is associated with an individual
buffer that can store a CM601 remote
command string for later transmission to the
modem chassis.
MDC
Modem Data Clear
Config (V)
- = clears all buffers
1 to 9 = clears specific buffer
—
Clears the specified MD buffer (MD1 through
MD9); no parameter clears all MD buffers.
MDP
Modem Data Parity
Config (NV)
0 = 7 data bits with odd parity
1 = 8 data bits with no parity
0
Sets the remote format; asynchronous
character format for the CM601 remote
interface is independent of packet or ASCII
remote protocol selection.
MDR
Modem Data Time
Remaining
Monitor
- or ?
—
Determines the number of seconds remaining
until the MD buffers are executed; if MDT is not
active, returns an ER 4.
MDS
Modem Data Stop
Config (V)
—
—
Stops the MDT process and clears the MDT
value; if the MDS command is issued after the
MD buffers have begun to execute, it is ignored.
MDT
Modem Data Time
Config (V)
absolute: 00:00:00 to 23:59:59
seconds: 0 to 172800
—
Sets the time (or time delay) for executing the
commands buffered in the MD commands; time
value can be entered in absolute time or in
seconds. The absolute time is relative to the
CM601 real-time clock.
MEI
Modem Electrical
Interface
Config (NV)
0 = RS-232
1 = RS-485
0
Sets remote port to RS-232 or RS-485.
MFS
Modulator
Baseband Filter
Select
Config (NV)
0 = ComStream closed network
1 = Intelsat-compatible, open
2 = Eutelsat-compatible, open
0
Selects the spectral shape of the modulated
TxIF signal; modulator digital filter coefficients
are programmed to create an optimal match to
the demodulator baseband digital filter, which
results in exceptional modem performance.
MI
Modulator Spectral
Inversion
Config (NV)
0 = disable
1 = enable
0
Controls the transmit spectral inversion feature
on the modulator.
ML
Modulator Latching
Clock
Config (NV)
0 = TT clock
1 = ST clock
1
Selects the clock to be used by the modulator
to latch the transmit data (SD) into the CM601;
when the modulator is using external timing,
this command has no effect and the TT clock is
always selected.
MLB
Modem Card
Loopback Mode
Config (V)
0 = disable
2 = near data
4 = far data
0
Tests and troubleshoots system connections
when the data I/O interface on the modem card
is used instead of a data I/O card.
MPA
Modem Packet
Address
Config (NV)
1 to 31
1
Sets the device address when packet protocol
is selected for the remote protocol. The Packet
Address command is not used with ASCII
protocol operation.
MPT
Modem Protocol
Type
Config (NV)
0 = ASCII
1 = ComStream packet
0
Selects the protocol used for the CM601
remote port.
