Function Description
HDCP-MOD? Get HDCP mode.
Set HDCP working
mode on the device input:
HDCP supported -
HDCP_ON [default].
HDCP not supported -
HDCP OFF.
HDCP support changes
following detected sink -
MIRROR OUTPUT.
HDCP-STAT? Get HDCP signal status.
io_mode =1 – get the
HDCP signal status of the
sink device connected to
the specified output.
io_mode =0 – get the
HDCP signal status of the
source device connected
to the specified input.
HELP Get command list or help
for specific command.
LDEDID Write EDID data from
external application to
device.
When the unit receives
the LDEDID command it
replies with READY and
enters the special EDID
packet wait mode. In this
mode the unit can receive
only packets and not
regular protocol
commands.
If the unit does not receive
correct packets for 30
seconds or is interrupted
for more than 30 seconds
before receiving all
packets, it sends timeout
error
~nn@LDEDIDerr01<CR
><LF> and returns to the
regular protocol mode. If
the unit received data that
is not a correct packet, it
sends the corresponding
error and returns to the
regular protocol mode.
LOCK-FP Lock the front panel.
In NT-52N, this
command includes the
PortNumber (1-2)
parameter.
LOCK-FP? Get the front panel lock
state.
In NT-52N, this
command includes the
PortNumber (1-2)
parameter.
MODEL? Get device model.
This command
identifies equipment
connected to VS-42H2
and notifies of identity
changes to the connected
equipment. The Matrix
saves this data in memory
to answer REMOTE-INFO
requests.
