Protocol 3000 Commands - Kramer VSM-4x4X User Manual

Protocol 3000 Commands

Function Description
# 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.
AUD-LVL
Set volume level.
AUD-LVL?
Get volume level.
AUD-LVL-
Get audio level min
RANGE?
and max range.
In most devices
min and max audio
level is a function of
HW implementation
and the SET
command is usually
not implemented.
AUD-SIG-
N/A
TYPE
AUD-SIG-
N/A
TYPE?
BEACON- Get beacon
INFO? information, including
IP address, UDP
control port, TCP
control port, MAC
address, model,
name.
There is no Set
command. Get
command initiates a
notification.
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.
