Connection Modules
Different connection modules can be fitted depending on a system's configura-
tion and expansion. They are installed behind the openings provided in the front
panels. Unused openings in the front panels can be closed using dummy covers.
The connection modules and the dummy covers can be supplied singly. There are
three different types of connection modules:
ab/AD2 Connection Module
The ab/AD2 connection module contains 8 RJ45 sockets for 8 a/b and/or 8 AD2
interfaces. The wiring to the expansion cards consists of one prefabricated 16-
wire connecting cable or 4 quad two-conductor pillar terminal blocks. The
second connection variant allows a/b and AD2 interfaces to be wired to the same
connection module. The assignment of the 16-wire connecting cable, and also of
the 16-pin cable on the connection module, is described in the Chapters "User-
network interfaces a/b", page 783 and "AD2 user-network interfaces", page
766.
