a dash. Output ports may be individually disconnected from the broadcast using
the disconnect command
The
D
, or disconnect, command will disconnect the specified ports from one
another. This command may also be used to disconnect all the connections in
the Matrix-Hub or all connections in an internal chassis. To disconnect a single
connection, the chassis ID number, the input number, and the output number
must be specified in that order. To disconnect all the connections on one internal
chassis, enter the chassis ID number followed by the command qualifier
ALL
. To
disconnect all connections in the Matrix-Hub, use
D ALL
. The disconnect
command may also be used to disconnect entities from one another.
Connections that are broken using the disconnect command may be made again
by using the
RESTORE
command.
The
CLEAR
command breaks all connections, either in the entire Matrix-Hub or
only in an internal chassis (if the chassis ID number is specified), and removes all
record of the connection. The
RESTORE
command (see below) will not work
when connections are cleared. The
CLEAR
command also works after using the
D
command; it simply removes the record of the broken connections so that the
RESTORE
command will not work. Caution must be exercised when using the
CLEAR
command to prevent inadvertent disconnection of active connections.
The
RESTORE
command re-establishes connections that were broken using the
D
command. The command is not selective, and all connections that have been
broken and not cleared will be reconnected.
If a connection exists between two ports and one of those ports is included in a
new connect or broadcast command, then the existing connection will be broken
in favor of the new connection. However, the connect command will take slightly
longer than usual to execute while the previously existing connection is broken.
8.4.1 Serial Connections
Serial connections are established in a command syntax identical to other
connection types. However, the syntax varies slightly since two types of serial
connection are possible: RS-232 and RS-422. If just the serial port number (e.g.,
5) is specified in the connect command, then the connection will be made using
the RS-232 protocol. If 100 is added to the serial port number (e.g., 105), then
the connection will be made using the RS-422 protocol. The different protocols
may not be mixed. That is, a port specified as RS-232 in the connect command
may not be connected to a port specified as RS-422. This applies to entity and
macro commands as well; an entity that has an RS-232 serial connection
specified may not connect to an entity with an RS-422 serial connection, nor may
a macro be used to connect two ports with different protocols. When switching
the stereo emitter, the Matrix Hub must be in RS-422 mode.
