8.8. 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 section 5.3. on page 44 about
EDID memory structure.
8.8.1. Change EDID on input
Description: Copy EDID from memory location <loc2> to input port <loc1>.
Command {<loc1>:<loc2>}
Response (E_SW_OK)CrLf
Explanation: Factory EDID #10 is copied to input 5.
Legend:
Info: 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.
Info: If <loc2> is 'Dxx' then dynamic EDID routing occurs. In this case the router will follow the
EDID changes on the output. Every time a different EDID is recognized on the output, it is
copied instantly to the input.
Info: The router sends (E_S_C) only if the new EDID is different from the earlier one.
8.8.2. Change 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.
Command {EA:<loc2>}
Response (E_SW_OK)CrLf
Explanation: User EDID #2 is copied to all inputs.
Info: This operation can take several seconds depending on the frame size.
8.8.3. Save EDID to user memory (Learn EDID)
Description: Learn EDID from <loc2> to <loc1>.
Command {<loc1>:<loc2>}
Response (E_SW_OK)CrLf
Explanation: EDID from output 3 is saved to user EDID #4.
Legend:
8.8.4. View emulated EDIDs on all inputs
Description: Shows the currently emulated EDIDs for each input. The response length
depends on the frame size (number of inputs). The value at the given index
(<in1>..<inN>) shows which EDID is used on that particular input.
