3.4 Router Initiated commands

3.4.1 EDID status changed

Description: This is sent after all
commands which changes the
EDID (EDID copy, EDID switch),
or after a new EDID source ie. a
new display device is connected
to the router.
Examlpe # 1: After routing EDID to a selected output.
Examlpe # 2: After routing EDID to a selected output.
Connecting a new display ie. a new LC display, to one
output.
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 the same
manufacturer)
Info To keep your application in sync with the router it is recommended to issue a show
validity ( {wv} ) command after receiveing 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.
