MidiBox 64E sending and receiving system exclusive messages

Hi!

I have a program that communicates only system exclusive messages. Is it possible to learn the buttons connected to the DIN to be able to send this messages and that the diode connected to the DOUT respond to feedback messages?

Sample code sent when switching on ( from midi-ox ):

SYSX: F0 7F 7F 02 01 01 31 2E 30 30 30 00 32 31 2E 31 F7

and sample code sent when switching off :

SYSX: F0 7F 7F 02 01 0A 30 2E 30 30 30 00 32 31 2E 31 F7

Regards

Daniel

P.S.

or maybe can only LED’s connected to the DOUT have feedback on/off receiving SysEx from the program ?
