8.7.8. Download EDID content from the router
Description: EDID hex bytes can be read directly. The router will issue the whole content
of the EDID present on memory location <loc> (256 bytes).
Format
Example
Command
{WE<loc>}
→
{we1>}
Response
(EB#<loc>●<B1>
●<B2>●..●<B256>)CrLf
←
(EB#1 00 FF FF FF FF FF FF 00 32
F2 00 00 00 .. .. .. 00 92) CrLf
Legend: <B1>..<B256> are space separated hex characters represented in ASCII format.
Explanation: Full EDID from memory location 1 is downloaded.
8.7.9. Upload EDID content to the router
Description: EDID hex bytes can be written directly to the user programmable memory
locations (locations #51...#100).
Sequence:
Step 1. Prepare the router to accept EDID bytes to the specified location <loc> with
command {WL#<loc>}
Step 2. Router responds that it is ready to accept EDID bytes with (E_L_S)CrLf
Step 3. Send 1 block of EDID (1 block consist of 8 bytes of hex data represented in ASCII
format) with command {WB#<num>●<B1>●<B2>●<B3>●<B4>
●<B5>●<B6>●<B7>●<B8>}
Step 4. The router acknowledges with response (EL#<num>)
Step 5. Repeat steps 3 and 4 to send the remaining 31 blocks of EDID (32 altogether)
Step 6. After the last acknowledge, the router indicates that the EDID status changed by
sending (E_S_C) CrLf

(E_S_C) CrLf
Legend: <num> represents the sequential number of every 8 byte part of EDID. <num> is
between 1 and 32. <B1>..<B256> are the bytes of EDID.
Explanation: Full EDID uploaded to memory location 53.
