Downloading the Content of an EDID
EDID hex bytes can be read directly. The router will issue the whole content of the EDID present on memory
location
<loc>
(256 bytes).

Uploading the EDID Content
EDID hex bytes can be written directly to the user programmable memory locations. The sequence is the
following:
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 is changed by sending (E_S_C)
