8.8.3. EDID status changed
Description: This is sent after all commands which changes the EDID (EDID copy, EDID
switch), or after a new EDID source e.g. a new display device is connected to the router.
Explanation: Copy EDID from output 1 to input 5 (dynamic emulation). First response
confirms the EDID routing command. (E_S_C) response is an automatic message that is
sent because an EDID has changed.
Info: The router stores the last attached display device’s EDID connected to the output. After
disconnecting this device its EDID is still present at the router’s memory, therefore no status
change message is issued by the router if a display device having the same EDID is
connected to that output. (The same display device is connected again, or another display
device (same brand) from the same manufacturer)
Info: To keep your application in sync with the router it is recommended to issue a show validity
( {wv} ) command after receiving an EDID status changed response, and read all location
indicating ’3’ in the table, as the change of these EDID triggered the EDID status changed
response.
