Switcher-Initiated Messages

When a local event such as power-up or a front panel operation occurs, the
switcher responds by sending a message to the host. The switcher-initiated
messages are listed in the following pages. The messages are underlined.

The switcher does not expect a response from the host; but, for example, the host
program might request a new status.

Power-up
