3.5.4.5 PC

It is possible to connect a PC for remote control of the matrix or for the firmware update using a standard 9-pin
serial extension cable
(DB9M - DB9F) and connecting it to the matrix DB9 (“PC”) socket.
If the Macro communication protocol, given in the appendix, is used it is possible to completely control the
matrix and record noteworthy events when necessary.
