Chapter 3. Operation
3.1 Introduction
This chapter will go into the details of the specific configuration and operation of the
FMUX04. Broken into two parts, the first part outlines the procedures and functions when
using the front panel DIP switches for configuration. The second section will outline the
operation when using a VT-100 terminal connected to the RS-232 Console port. For more
complete operation, a terminal connection to the Console port is recommended.
