3.2 CPU Module

The main element of the IRRInet-XL RTU is the CPU Module (see Figure 3-2). The CPU
controls the I/O Modules, processes the data gathered, and communicates with external
devices. The CPU module is based on the Motorola 68LC302 microprocessor and
includes on-board memory, communication circuits, I/O bus drivers, and other circuits.
The CPU Module is installed in the second slot from the left in the multi-slot I/O card cage.
