9284 Functional Description
1-16 9284 PRODUCT MANUAL 9284-OM (V1.3)
Note the dash, indicating that on level 2, output 65 is not connected to an
input. Also note the 0, indicating that the connection on level 3 is either
unknown or that output 65 doesn't exist or isn't mapped on level 3.
Or, a 3-level router might have the following single command as its
Response:
** V65,23,-,0 !!
which has the same information as the three X commands in the previous
example.
If the router has only one level, or if all levels are connected the same, the
router might instead use the Y command. For example:
** Y65,23 !!
The number of digits used for each number depends on the router. Newer
routers use the minimum number of digits necessary, i.e. there are no
unnecessary leading zeroes in a number. Older routers use the maximum
number of digits ever required for an input or output number on that particular
router (e.g. a router with between 10 and 99 inputs would use two digits for
the input number).
“N”: Input Status Inquiry
The command “ N ” requests that matrix status information for a single input
be returned to the host. The status information is sent as one or more “Y” and/
or “X” commands. This command works by identifying all outputs that
connect to the specified input on any level, and then generating “Y” and “X”
status commands to report the status of those outputs. The “Y” and “X”
commands are formatted exactly as with the “O” command. For any given
output connected to the input, a “Y” command is used if the output is
connected to the input on all levels, else “X” commands are used on all levels
on which the input is connected to that output.
From Syntax Description
