SDM-2020 Satellite Demodulator
Remote Control Operation
Rev. 3
B–17
Notes:
1.
Parameters 2 through 6 are dependent on carrier acquisition, if the decoder is not locked empty data blocks are returned
(,,,).
2.
Parameters 5 and 6 display only if G.703 interface is installed
Bulk

Status
Command:
Response:
Status:
Response:
<add/BCS_'cr'
>add/BCS_p1,p2,p3, . . . pn'cr''lf']
This command causes bulk demodulator status to be returned.
To reduce the length of the response, message parameter
data are returned without identifiers. However, parameter
identification can be determined by order of return. Each status
parameter is terminated with a ',' (comma) except for the last
parameter which has the standard message termination
sequence ('cr''lf']). Most of the data returned is formatted the
same way as the single command status request (refer to the
appropriate portions of this document in preceding sections).
Additional configuration status of new options and features will
always be appended to the end.
Where 'pn' is the last parameter returned.
