Communication Protocols

"U": Automatic Output Change Reporting On/Off

Request: **U!! { 0 1 2 }

Response: (none)

Action: Turn automatic output change reporting off or on.

The command "U" turns on or off the automatic sending of output change reports. The command letter must be followed by either a number 0, 1, or 2 to specify the new automatic change report state, as follows:

*0: Automatic output change reporting is turned off.

*1 or 2: Automatic output change reporting is turned on, and crosspoint change commands immediately report changed.

Output change reports are automatic messages sent to the host whenever an output©s crosspoint status (i.e. connected source) is change via either the local control panel or via some other port.

Changes are reported in the same structure as described for the S command, except there may be fewer lines to the report.

For example, the command: **U1!!

turns on automatic output change reporting. The format of crosspoint reporting is the same for U, S and ? messages.

"?": Query command

Request: **X5?!!

Response: **5,3,3,3,3!!<CR>

Action: The status of the previous command is requested.

The "? " Query can be added in a command string to cause a response back to the host with selected status information.

The ? command can be placed in a shortened X command as illustrated bellow to give the status of a single output.

**X5?!!

The ? command can be put at the end of a valid X command to give the status of a switch after it is made. Such as

**X5,4,1?!!

In which case the response will confirm that that the above crosspoint selection has been effected. Or it can be used multiple times in a command string:

**X6?X5,4,1?!!
