Response:
When the BCME_command is executed, the
host M&C will inspect all of the supplied
parameters of the Bulk Modulator Command
(BMC_) for failure. If any particular parameter
or any combination of parameters is invalid or
out of range, the resulting output error listing
will allow the user to evaluate which
parameters caused the error.
The output error listing is a series of 40
characters, which are either a 1 or a 0,
commas delimited. A listing of all 0 would
indicate that there were no errors. A 1 in
position 1 and position 17 might indicate that
the symbol range of the modulator was
exceeded (Data and Code Rate are
programmed in position 1 and framing type
which affects symbol rate would be position
17).
This command is a status request only, and is
cleared after another BMC_ command is
issued. The BMCE_command will alaways
report the status of all 40 parameters,
whether these parameters are used or
reserved.
Note: Parameters 23 through 40 are interface
dependent. Ensure to refer to the
BMC_command for the particular type of
interface that is installed in the modulator.
Where'pn40' is the last parameter returned.
