Suppose we have a MCN system like the one shown in Figure 33. In this system,
there are three MCN I/O modules being monitored and controlled by the PC,
which is running MCNRCD. Each module is connected to a different type of I/O
device. The Comparator I/O Module is connected to a RF receiver comparator
system, Input/Output Control Module 1 is connected to an alarm system and
Input/Output Control Module 2 is connected to a control system.

Figure 33 - MCN System With Multiple I/O Types
Because there are three types of I/O devices being monitored and controlled, we
need to define three separate categories in the MCNRCD.CFG file so that we can
monitor all three MCN I/O modules on a single MCNRCD screen file. These
three categories will define the text that is displayed for each MCN I/O module.
Figure 34 shows an example MCNRCD.CFG file that contains the three
categories.
Notice that each category can have a variable number of text definition lines.
Also notice that each category specifies different operation of the keyboard and
mouse buttons.
