VS-44H2A – Protocol 3000

Function
Description
Syntax
Parameters/Attributes
Example
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.
COMMAND
Multi-step syntax
FEEDBACK
Step 1:
#LDEDIDedid_io, dest_bitmask, edid_size, safe_mode<CR>
Response 1:
~nn@LDEDIDedid_io, dest_bitmask, edid_size,
safe_modeready<CR><LF>
or
~nn@LDEDIDerrnn<CR><LF>
Step 2: If ready was received, send EDID_DATA
Response 2:
~nn@LDEDIDedid_io, dest_bitmask, edid_size,
safe_modeok<CR><LF>
or
~nn@LDEDIDerrnn<CR><LF>
edid_io – EDID destination type
(usually input)
0 – Input
1 – Output
2 – Default EDID
3 – Custom EDID
dest_bitmask – Bitmap representing
destination IDs. Format: 0x********,
where * is ASCII presentation of hex
digit. The binary presentation of this
number is a bit mask for destinations.
Setting ‘1’ means EDID data has to be
copied to this destination
edid_size – EDID data size
safe_mode – Safe mode
0 – Device accepts the EDID as is
without trying to adjust
1 – Device tries to adjust the EDID
edid_data – Data in protocol packets
Using the Packet Protocol
Send a command: LDRV, LOAD,
IROUT, LDEDID
Receive Ready or ERR###
If Ready:
a. Send a packet,
b. Receive OK on the last packet,
c. Receive OK for the command
Packet structure:
Packet ID (1, 2, 3…) (2 bytes in
length)
Length (data length + 2 for
CRC) – (2 bytes in length)
Data (data length -2 bytes)
CRC – 2 bytes

5. Response: ~nnnnok<CR><LF>
(Where NNNN is the received
packet ID in ASCII hex digits.)
Write the EDID data from an
external application to the HDMI
In 1 input without adjustment
attempts:
#LDEDID0,0x1,2340,0<CR
>
Write the EDID data from an
external application to HDMI In
1 and PC In inputs with
adjustment attempts:
#LDEDID0,0x5,2340,1<CR
>
LOAD
Load file to device.
COMMAND
#LOADfile_name, size<CR>
FEEDBACK
Data sending negotiation:
* Device -
~01@LOADfile_name, sizeready<CR><LF>
* End User (+Device)-
Send file in Protocol Packets
* Device -
~01@LOADfile_name, sizeok<CR><LF>
file_name – Name of file to save on
device
size – Size of file data that is sent

LOCK-FP
Lock the front panel.
In NT-52N, this
command includes the
PortNumber (1-2)
parameter.
COMMAND
#LOCK-FPlock/unlock<CR>
FEEDBACK
~nn@LOCK-FP lock/unlock<CR><LF>
lock/unlock – On/Off
0 – Off unlocks EDID
1 – On locks EDID

Get the front panel lock
state.
In NT-52N, this
command includes the
PortNumber (1-2)
parameter.
