6.4.7. 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 1.
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
●<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
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.
