Note
1) If a customer uses 6 port extension boards, above configuration will be a little different shape.
2) Even though a customer uses 2B modules in GDK-100, the maximum capacity will be the same.
2B module can be connected to the every even-numbered port (0,2,4,...) of the boards like
DTIB12/DTIB24/DSIB, then any DKTU can not be connected to the consecutive port(1,3,5,...) in
this case.
