Introduction
This manual provides guidelines on the fiber-optic cabling used to connect AutoMax ™
Distributed Power System Universal Drive Controllers (UDC) and Power Module
Interfaces (PMI). The cable is immune to electromagnetic interference (EMI) and
eliminates ground loops.
The fiber-optic cable is a part of a point-to-point serial communication link between the
UDC module and the PMI. See figure 1.1.
The link allows the UDC module to transfer configuration, operating system, and
real-time control information to the PMI. The PMI in turn sends feedback and status
information to the UDC module. The UDC module is capable of supporting two links
operating independently of each other.
Data transferred over the fiber-optic link is Manchester-encoded and is transmitted at
a rate of 10M bits per second. Fiber-optic link specifications are provided in
Appendix A.
