6.1.1.2 Host Response

The AV1 does not expect any response from the HOST.

6.1.2 Sleep Notification

By transmitting the Sleep Notification, AV1 indicates the unit is shutting down into a standby mode. Because
the hard power switch could be activated independently of the AV1 system software, hard power down will
not be notified. Acknowledgment of the Sleep Notification is not required. This notification is primarily for the
HOST to know the operating status of the AV1.

6.1.3 Front Panel Display

AV1 will transmit the front panel display buffer following the update to the AV1 front panel display. The AV1
front panel display is 2 X 20 ASCII character display. The HOST can enable transmission of this notification
message by sending Host Wakeup (6.3.5 page 13). To disable transmission the HOST can
send Host Sleep (6.3.6 page 14). Transmission of the display buffer is asynchronous to other host/AV1
communication and will only transmit following the completion of any communication exchanges in progress
or pending.
