The different types of Functional Modules are used to produce a variety of
configurations. In the MGC-50 up to eight individual Functional Modules can
be used to build the desired configuration. In the MGC-100, 16 modules can
be used.
Figure 4-12 shows the general design of the Functional Modules. The
components that are common to all Functional Modules are shown in detail in
the figure and are described in Table 4-5 on page 4-27.
