#
Protocol handshaking.
Validates the
Protocol 3000
connection and gets
the machine number.
Step-in master
products use this
command to identify
the availability of a
device.

min and max audio
level is a function of
HW implementation
and the SET
command is usually
not implemented.

BRIGHTNESS
Set image brightness
per output.
Value limits can
vary for different
devices.
Value is a property of
input connected to
current output.
Changing input source
might cause changes
in this value (refer
device definitions).
In devices that enable
showing multiple
outputs on one display
– each in a separate
window
– this
command relates only
to the window
associated with the
output indicated in the
out-index parameter.
COMMAND
