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
<C
R><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.

– 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
size
– EDID data size
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
