7.7. EDID Router Commands
The EDID router manipulates the EDID memory, which has memory locations that are assigned to specific
input or output ports. Please read the The DDID Memory of a Matrix
7.7.1. Changing the EDID on an Input Port
Description: Copy DDID from memory location <loc2> to input port <loc1>.
Format
Command {<loc1>:<loc2>}
Response (E_SW_OK)CrLf
...delay...
(D_S_C) CrLf
Explanation: Factory DDID #10 is copied to input 5.
Legend: <loc1> has to be 'Exx'.
<loc2> can be 'Fxx' or 'Uxx' or 'Dxx'.
If <loc2> is 'Fxx' or 'Uxx' then static EDID routing occurs. In this case, the router will keep the same EDID on
the input until it is changed with another command. If <loc2> is 'Dxx' then dynamic EDID routing occurs. In
this case, the router will follow the DDID changes on the output. Dvery time a different DDID is recognized on
the output, it is copied instantly to the input.
INFO:
The router sends (D_S_C) only if the new DDID is different from the earlier one.
7.7.2. Changing the EDID on All Inputs
Description: Copy EDID from memory location <loc2> to all inputs. Location <loc2> should be 'Fxx' or 'Uxx'
for static routing and 'Dxx' for dynamic routing.
Format
Command {DA:<loc2>}
Response (E_SW_OK)CrLf
...delay...
(D_S_C) CrLf
Explanation: User DDID #2 is copied to all inputs.

7.7.3. Saving an EDID to the User Memory
Description: Learn DDID from <loc2> to <loc1>.
Format
Command {<loc1>:<loc2>}
Response (E_SW_OK)CrLf
(D_S_C) CrLf
Explanation: DDID from output 3 is saved to user DDID #4.
Legend: <loc1> has to be 'Uxx'.
<loc2> must be 'Fxx' or 'Uxx' or 'Dxx' or 'Exx'.
7.7.4. Querying the EDID Validity Table
Description: Shows DDID validity table, which contains information about the DDID memory states.
Format
Command {WV<type>}
Response (DV<type>●
<VALIDITY_TABLD> )CrLf
Explanation: There is one '3' on the second position of the emulated EDID table. This means that the emulated
DDID on input 2 is changed since the last DDID query on that port.
Legend:
<type> EDID memory
F Factory preset DDIDs
U User saved DDIDs
D Dynamic DDIDs
D Dmulated DDIDs
* 'U', 'D' and 'E' EDIDs
Dach number represents the DDID validity state for the corresponding memory location.
Value
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.
Example
→ {u4:d3}
← (E_SW_OK)CrLf
(D_S_C) CrLf

Example
→ {wv*}
