Operation of the EDID management
The ASP matrix switcher has built in the EDID management database. The EDID
management can be automatic, manual, and factory restored.
Automatic EDID
The ASP matrix switcher has built in the EDID data, which can communicate with the
displayers and video source automatically. When the displays or video sources are
connected to the ASP matrix switcher, they will share the EDID/DDC information with the
matrix switcher.
The ASP EDID database includes the most popular display data. You can manually refresh
the EDID data to update the EDID data base.
EDID hand-shake priority
The EDID refresh ports have the priority grade, ranging from output 1 to output 8 in priority
order. It means the output 1 is the highest priority to exchange the EDID data, and then
output 2 all the way to output 8 which has the least priority.
When the user carries out the EDID erase/refresh function, the ASP will detect the output
priority and exchange the EDID data with the available most priority output port.
EDID management by RS232 commands
When you need to refresh the EDID data of the ASP matrix switcher, you can manually
exchange the EDID data by sending the RS232 command “EDIDMOn.” (Please notice the
text-transform, and the period at the end.)
Erase and Refresh the EDID data
When the “EDIDMOn.” is sent, the ASP matrix switcher will copy the EDID data from the
output port with priority. It means the ASP will erase the old EDID data, and fully copy the
EDID data from the display which is connected to the highest priority output port.
EDID restore to factory default
When you send the “EDIDMInit.” to the matrix switcher, it will recover the factory default
EDID data.
RS232 feedback:
When the “EDIDMOn.” or “EDIDMInit.” is correctly sent all the connected displays will be
