7.7.3. Save EDID to user memory (Learn EDID)
Description : Learn EDID from <loc2> to <loc1>.
Format Example
Command {<loc1> : <loc2>}
→ {u4:d3}
Response (E_SW_OK)CrLf
(E_S_C) CrLf
←

(E_SW_OK)CrLf

Legend: <loc1>
must be ‘Uxx’.
Explanation: EDID from output 3 is saved to user EDID #4.
7.7.4. View emulated EDIDs on all inputs
Description : Shows the currently emulated EDIDs for each input. The value at the given
index (<in1>..<in4>) shows which EDID is used on that particular input.
Format Example
Command {VEDID}
→ {vedid}
Response
(VEDID●<in1>●<in2>●
<in3>●<in4>)CrLf ←
(
VEDID F049 D001 F029 U007)CrLf
Legend: All <inx> indexes show a <loc> which was copied to that input port.
Explanation : F049 (Factory preset EDID F49) is emulated on the input 1. EDID from output
1 is dynamically emulated on input 2. F029 (Factory preset EDID F29) is emulated on the
input 3. U007 (User saved EDID U7) is emulated on input 4.
7.7.5. Watch EDID validity table
Description : Shows EDID validity table, which contains information about the EDID
memory states.
Format Example
Command {WV<type>}
→ {wv*}

F Factory preset EDIDs 100
U User saved EDIDs 50
D Dynamic EDIDs 4
E Emulated EDIDs 4
*
All ‘U’, ‘D’ and ‘E’ EDIDs
Each number represents the EDID validity state for the corresponding memory location.
Value Description
‘0’
invalid EDID
‘1’
valid EDID
‘2’
deleted EDID
‘3’
changed EDID
Explanation:
There is one ‘3’ in the last row on the 4
th position. This means that the
emulated EDID on input 4 is changed since the last EDID query on that port.
Info: If a changed EDID is queried by the {WH} command (see the next section), its value returns
to ‘1’. The status of a deleted EDID returns to ‘0’ after query.
