Lightware UMX-OPT-TX150R - Upload EDID Content to the Transmitter; Delete EDID from Memory

Page 80 / 107 Section 10. Programmers reference
10.5.6. Upload EDID content to the transmitter
Description: EDID hex bytes can be written directly to the user programmable memory
locations.
Sequence:
Step 1. Prepare the device to accept EDID bytes to the specified location <loc> with
command {WL#<loc>}
Step 2. Device 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 device 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 device 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.
