1.1 MCN System Overview
Figure 1 shows a basic MCN comparator display system. The MCN system is made up of two
modules, a Comparator I/O Module and a User Interface Module. The Comparator I/O Module
provides the hardware interface to the comparator. The User Interface Module provides the mechanism
for the user to monitor and control the comparator.

The Comparator I/O Module and the User Interface Modules connect with a single cable between the
network ports of the modules, simplifying system installation. Standard systems can include up to 20
Comparator I/O Modules in a single network segment. Larger comparator display systems consisting
of multiple network segments tied together with routers/repeaters can be custom configured by CTI
Products, Inc.
Together, the Comparator I/O Module and the User Interface Module provide a simple, cost effective
way to control your comparator system. Because of the MCN system’s modular design, your
comparator display system can easily expand as your communications system grows.
