Table 10A.U lists the connectors used to make the fiber optic connections
to the I/O ring. Each module connected to the system I/O ring has an
optical transmitter and receiver. Fiber optic cables connect transmitters to
receivers to form the I/O ring. Refer to Appendix A for additional
information on fiber optic cables and connectors.

OP22 (BLacK) Transmitter on previous module in I/O ring Input
Different types of I/O devices can have the same node address, but devices
of the same type must each have a unique node address. Each digital I/O is
assigned a unique node address in the I/O assignment file of ODS. This
address corresponds to a switch setting on the device itself.
Figure 10A.25 shows the location of the node address switch assembly on
the digital I/O.
