xpmt (crosspoint mute)
This command is used as a query to read the matrix
crosspoint mute status, or as an update to set the sta-
tus. The crosspoint is specified by using the two dimen-
sional 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, either “1” meaning that the
crosspoint is muted, or “0” meaning that it is not muted.
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 mute is to
remain unchanged
by the com-
mand.
Examples:
Request Response
Query
xpmt(3,19)?<CR> OK 1<CRLF>
Query
xpmt(5,*)?<CR> OK{0,0,...,1,0}<CRLF>
Update
xpmt(16,1)=0<CR> OK<CRLF>
Update
xpmt(15,*)=
{3,1,3,...,99,99,3}<CR> OK<CRLF>
xpmttog (crosspoint mute toggle)
This command is used as a simple command to toggle
the matrix crosspoint mute status. The crosspoint is
specified by using the two dimensional address syntax.
Addresses for the first dimension (input channel) must
be in the range 1 to 16. Addresses for the second di-
mension (output channel) must be in the range 1 to 24.
Example:
Request Response
Command
xpmttog(3,19)<CR> OK<CRLF>

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.
