module
If the expansion units are used, the expansion interface modules
must be mounted in each of the basic unit and the expansion units.
There are basically two types of expansion interface modules-the
standard type and the long-distance type. What type to use will
depend on the cable distance. The dedicated expansion interface
module must be mounted on each of the basic unit and the
expansion units.
