If the syntax of a command is incorrectly entered, the command will be ignored or the switch will answer with a bad response ?<CR>.

Autostatus

When Autostatus is enabled, any output-to-input connection change in the NODEMUX will cause an Autostatus message to be sent via RS232 to the administrator. The format of the message would be "pc SW,OP:IP<CR>"

Example of an Autostatus message:

pc 01,01:04<CR>

which means "At the switch with unit address 01, the output (01) has changed connection to input 04."

Notes: Message to the administrator will be delayed by any RS232 traffic being received by the switch from the administrator.

Autostatus must be disabled before using SerTest or the Matrix Switcher's Control Program (page 20).

By default, Autostatus is disabled and must be manually enabled. Autostatus is also disabled any time the power to the NODEMUX is interrupted.
