DMPA12 Output Limiter Commands
Command Description
outlmgn Output limiter gain
outlmtc Output limiter time constant
outlmthr Output limiter threshold level
Termination: all commands are terminated with an
ASCII carriage return character (hex code 0x0D), rep-
resented by <CR> in the examples below. All responses
are terminated with an ASCII carriage return, line feed
pair (hex codes 0x0D, 0x0A), represented by <CRLF>
in the examples below. An ellipsis (...) represents
members of an array that have been omitted from an
example for the sake of brevity.
Verbose response: commands prefixed with an ex-
clamation point (bang) character result in a “verbose”
response containing the name of the property or ac-
tion being addressed, along with the current values of
the property in question. Property values are always
returned in the “assignment” form, for example out-
mt(2)=1. This supports certain 3rd party control pro-
gramming styles where the response to all responses
needs to be self-describing and/or contain current
property values.
Examples:
REQUEST RESPONSE
COMMAND !store(3)<CR> OK store(3)<CRLF>
COMMAND !run={1,3,5}<CR> OK run={1,3,5}<CRLF>
QUERY !outgn(3)?<CR> OK outgn(3)=0<CRLF>
QUERY !outmt(*)?<CR> OK outmt(*)={0,1,1,...,0,0,0}
<CRLF>
UPDATE !outgn(3)=0<CR> OK outgn(3)=0<CRLF>
UPDATE !outmt(*)={0,1,1,...,
0,0,0}<CR> OK outmt(*)={0,1,1,...,0,0,0}
<CRLF>
outlmgn (output limiter gain)
This command may be used as a query to read the
limiter gain. The output channel is specified by using the
address syntax. Addresses must be in the range 1 to
12. The data type is integer, representing the gain in dB,
which is always a negative value if the limiter is active,
or zero.
Example:
REQUEST RESPONSE
QUERY outlmgn(1)?<CR> OK -11<CRLF>
outlmtc (output limiter time constant)
This command may be used as a query to read the time
constant, or as an update to set the time constant. The
output channel is specified by using the address syntax.
Addresses must be in the range 1 to 12. The data type
is integer, in the range 1 to 5000, representing the time
in one tenth millisecond increments.
Examples:
REQUEST RESPONSE
QUERY outlmtc(1)?<CR> OK 200<CRLF>
UPDATE outlmtc(2)=1000<CR> OK<CRLF>
outlmthr (output limiter threshold level)
This command may be used as a query to read the
threshold, or as an update to set the threshold. The
output channel is specified by using the address syntax.
Addresses must be in the range 1 to 12. The data type
is integer, in the range -50 to +20, representing the level
in dBu.
Examples:
REQUEST RESPONSE
QUERY outlmthr(1)?<CR> OK 10<CRLF>
UPDATE outlmthr(5)=15<CR> OK<CRLF>
