COMM Port Connections
Connect external interfaces to either the
COMM
1
(Serial A) and/or
COMM 2
(Serial B)
connectors as shown in
Figure 2.3
.
It is preferable to wire connections to Phoenix Contact™ plugs oriented as shown here rather than
assessing polarity on rear module connectors. Note that the orientation of rear module connectors
is not necessarily consistent within a rear module, or between different rear modules. If wiring is
first connected to the Phoenix Contact™ plug oriented as shown here, the electrical orientation
will be correct regardless of rear module connector orientation.
