The Host asks for the configuration of the Matrix. This includes information such
as: what type of switching modules are installed in which planes, etc.

additional string for each additional plane in the Matrix 200. They will be
transmitted in the ascending order of their board addresses (plane #1 first).
Where: BdAd = board (or plane) address (plane #1 = 80h, plane #2 = 81h, etc.)
#Inp = number of inputs on this plane
#Out = number of outputs on this plane
Tech = See table.
The Tech byte encodes the basic design characteristics for which the board in
that position was designed.
