Delete EDID from Memory
Description: Clear EDID from memory location <loc>.
Explanation: All user EDIDs are cleared from memory.
Legend: Depending on <loc>, one EDID or all EDIDs in a block can be cleared.
Download EDID Content
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).
Legend: <B1>..<B256> are space separated hex characters represented in ASCII format.
Explanation: Full EDID from memory location F1 is downloaded.

Upload EDID Content to the Router
Description: EDID hex bytes can be written directly to the user programmable memory locations. The
sequence is the following:

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

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.
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 U3.
