Parameters
dst_type -
EDID destination type (usually input)
– 0=input, 1=output, 2=Default 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 (see
Section
11.3.1
)
Response Triggers
Response is sent to the com port from which the

Notes
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
␍␊
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.
