4.4.

4.4.1. EDID status changed

Description: This is sent after all commands that

change the EDID (EDID copy, EDID switch), or after a

new EDID source ie. a new display device has been connected to the router.

Example # 1: After routing EDID to a selected output.

Example # 2: After routing EDID to a selected output.

Connecting a new display ie. a new LCD 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 in 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} ) → after receiveing EDID status changed response, and read all

locations indicating '3' in the table, as the EDID changes triggered the 'EDID status

changed' response.

4.4.2. Port Status Changed

Description: If STATUS_TABLE has changed, the

router will send this sequence to notify the controller

software. This event is useful to trigger the new {:ISD} and {:OSD} commands.

4.4.3. Router ready (after power up or restart)

Description: The router issues this command

after each power up. After this command the

router is ready to accept control commands.

Note:

During the booting process (before the ,,Router ready"

message) various messages are sent about the selftest

results.

(B:<message>)

Your control software should ignore these strings

because they are useful only in case of hardware

failure.
