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
