Command Description
xpgn Matrix crosspoint gain
xpmode Matrix crosspoint mix mode
xpmt Matrix crosspoint mute status
xpmttog Matrix crosspoint mute toggle
NOTE: All commands are terminated with an
ASCII carriage return character (hex code 0x0D),
represented by <CR> in the examples. All
responses are terminated with an ASCII carriage
return, line feed pair (hex codes 0x0D, 0x0A),
represented by <CRLF> in the examples. An
ellipsis (...) represents members of an array that
have been omitted from an example for the sake
of brevity.
xpgn (crosspoint gain)
This command is used as a query to read the matrix
crosspoint gain, or as an update to set the gain. The
crosspoint is specified by using the 2 dimensional ad-
dress syntax. Addresses for the first dimension (input
channel) must be in the range 1 to 16. Addresses for
the second dimension (output channel) must be in the
range 1 to 24, or wildcard. If the output channel is a
wildcard, then the command applies to the entire row
of the matrix associated with the specified input chan-
nel. The data type is integer, in the range -70 to +20,
representing the gain in dB. If an entire row is being
transmitted then the data type is array of integer of size
24. In this case the value 99 may be used in an update
to indicate that a particular crosspoint gain is to
remain
unchanged by the command.
Examples:
Request Response
Query
xpgn(1,17)?<CR> OK -3<CRLF>
Query
xpgn(1,*)?<CR> OK{0,3,0,...,0,0,0}
<CRLF>
Update
xpgn(15,22)=5<CR> OK<CRLF>
Update
xpgn(15,*)=
{0,5,...,99,99}<CR> OK<CRLF>
xpgnst (matrix crosspoint gain step change)
This command is used as an update to step the gain by
the amount specified, either up or down. The crosspoint
is specified by using the 2 dimensional address syntax.
Addresses for the first dimension (input channel) must
be in the range 1 to 16, or wildcarded. Addresses for
the second dimension (output channel) must be in the
range 1 to 24, or wildcarded. If the input is wildcarded,
then the command applies to the entire column of the
matrix associated with the specified output channel. If
the output is wildcarded, then the command applies to
the entire row of the matrix associated with the speci-
fied input channel. The data type is integer, in the range
DM1624F Matrix Crosspoint Commands
-6 to +6, representing the gain step in dB. A positive
value increments the gain, a negative value decrements
the gain. If an entire column is being transmitted then
the data type is array of integer of size 16. If an entire
row is being transmitted then the data type is array of
integer of size 24.
Examples:
Request Response
UPDATE xpgnst(2,2)=2<CR> OK<CRLF>
UPDATE xpgnst(*,3)={2,2,2,...0,0,0}<CR> OK<CRLF>
UPDATE
xpgnst(3,*)={-1,-1,-1,...0,0,0}<CR> OK<CRLF>
xpmode (crosspoint mix mode)
This command is used as a query to read the matrix
crosspoint mix mode, or as an update to set the mode.
The crosspoint is specified by using the 2 dimensional
address syntax. Addresses for the first dimension (input
channel) must be in the range 1 to 16. Addresses for
the second dimension (output channel) must be in the
range 1 to 24, or a wildcard. If the output channel is a
wildcard, then the command applies to the entire row
of the matrix associated with the specified input chan-
nel. The data type is integer, with the following values
allowed:
0
- means that the crosspoint is in DIRECT mode
1 - means that the crosspoint is in OVERRIDE mode
2 - means that the crosspoint is in BACKGROUND
mode
3 - means that the crosspoint is in AUTO mode
If an entire row is being transmitted then the data type
is array of integer of size 24. In this case the value 99
may be used in an update to indicate that a particular
crosspoint mix mode is to remain unchanged by the
command.
Examples:
Request Response
Query
xpmode(5,9)?<CR> OK 3<CRLF>
Query
xpmode(1,*)?<CR> OK{3,0,...,3,3}<CRLF>
Update
xpmode(16,1)=0<CR> OK<CRLF>
Update
xpmode(15,*)=
{3,1,3,...,99,99,3}<CR> OK<CRLF>
