2.1 Hardware Block Diagram
A Tank Gate Interface hardware functional block diagram is shown below. This diagram shows
the relationship between major subsystems and components in the Tank Gate Interface.
The heart of the Tank Gate Interface is an Intel 80C188EB microprocessor operating at 18.432
MHz. Designed specifically for real-time embedded applications, the µP includes timer/
counters, an interrupt controller, and chip-select circuitry. It also includes 2 serial channels that
are designated as COM0 and COM1.
2.2 Motherboard Description
The motherboard description is broken into three sections. Each section identifies the location
of the components on the motherboard. When necessary, a brief description of the component
is provided. These sections are listed below:
• Power Supply
• Switches and Indicators
• Communications
