F7-1 EDID communication
The MHD EDID database includes most popular displaying data, but not all the
displaying data because of the capability and firmware limitation. So, we can
manually refresh the EDID data to update the EDID data base.

EDID management of MHD matrix
1)
The RS232 commands for EDID management of MHD matrix models include:
”EDIDMInit.” and”EDIDM[X]B[Y].”, (Please notice the text-transform, and the dot
in behind.)
When we send the “EDIDMInit.” to the MHD matrix switcher, it will recover the
factory default EDID data. The feedback command is “EDIDMInit”.
When we send the RS232 command “EDIDM[X]B[Y].”. The matrix will copy the
EDID data of output[X] to the input[Y]. The feedback command is “EDIDM:
[X]To[Y]”.
2)
When a RS232 command is correctly sent, all the connected displayers will be
blank for 2~3 seconds and recover again. And, the MHD matrix switcher will send
out the RS232 feedback command.
3)
If all these symbols works, it means the action is taken.
