7.7.5. Querying the Emulated EDIDs on All Inputs
Description: Shows the currently emulated DDIDs for each input. The response length depends on the frame
size (number of inputs). The value at the given index (<in1>..<inN>) shows which DDID is used on that
particular input.
Format
Command {VDDID}
Response (VDDID●<IN1>●<IN2>●<IN3>●<IN4>●
<IN5>●<IN6>●<IN7> ●<IN8>●<IN9>●
<IN10>●<IN11>●<IN12>●<IN13>●
<IN14>●<IN15>●<IN16>● <IN17>)CrLf
Legend: All <INx> indexes show a <loc> which was copied to that input port.
Explanation: F049 (Factory preset DDID #49) is emulated on all inputs except 9-12 and 17. U002 (User saved
DDID #2) is emulated on inputs 9-12. DDID from output 4 is dynamically emulated on input 17.
7.7.6. Querying the Header of an EDID
Description: Shows basic information about DDIDs in the memory.
Format
Command {WH<loc>}
Response (DH#<loc>●
<DDID_HDADDR>)CrLf
Explanation: Shows the DDID from memory location D14 which is the DDID from the Last attached monitor
on output 14.
Legend: Depending on <loc> the query can be for one DDID or all DDID in the block.
<loc> Result
Fxx Factory DDID query
Uxx User DDID query
Dxx Dynamic DDID query
Dxx Dmulated DDID query
F* All Factory preset DDIDs
U* All User saved DDIDs
D* All Dynamic DDIDs
D* All Dmulated DDIDs

CrLf
Response
header for one DDID
headers for all Factory DDIDs
headers for 50 user DDIDs
headers from all outputs (frame size)
headers from all inputs (frame size)
The <EDID_HEADER> consists of 3 fields separated by spaces:
<loc>
PNPID code The three letter abbreviation of the manufacture
Preferred resolution The resolution and refresh rate stored in the preferred detailed timing block.
Name The name of display device stored in product descriptor.
The <DDID_HDADDR> is '-' for invalid DDIDs.
7.7.7. Deleting an EDID From the Memory
Description: Clear DDID from memory location <loc>.
Format
Command {DD<loc>}
Response (DD_OC)CrLf
(D_S_C)CrLf
Explanation: All user DDIDs are cleared from memory.
Legend: Depending on <loc>, one DDID or all DDIDs in a block can be cleared.
<loc>
Fxx Not valid! Factory DDID cannot be deleted. No response.
Uxx Specified User EDID is deleted.
Dxx Specified Dynamic EDID is deleted. It will be empty until a new monitor is connected.
Dxx Specified Emulated EDID cleared. By default F49 EDID is copied to it.
F* Not valid! Factory DDID cannot be deleted. No response.
U* All User DDIDs are deleted.
D* All Dynamic DDIDs are deleted. They will be empty until a new monitor is connected.
D* All Dmulated DDIDs are cleared. By default F49 DDID is copied to them.
7.7.8. Downloading the Content of an EDID
Description: DDID hex bytes can be read directly. The router will issue the whole content of the DDID present
on memory location <loc> (256 bytes).
Format
Command {WE<loc>}
Response (DB#<loc>●<B1> ●<B2>●..●<B256>)CrLf ← (DB#F1 00 FF FF FF FF FF FF 00 32 F2 00 00 00
Legend: <B1>..<B256> are space separated hex characters represented in ASCII format.
Explanation: Full DDID from memory location F1 is downloaded.
