THE PURPOSE OF THE INTERFACE POD The 9000A-80186 Interface Pod allows you to use any Fluke 9000-Series Micro-System Troubleshooter to troubleshoot equipment that uses an 80186 microprocessor. The Micro-System Troubleshooter (referred to hereafter as the Troubleshooter) is used to service printed circuit boards, instruments and systems that use microprocessors. The 9000A-80186 Interface Pod (referred to as the Pod) replaces the 80186 microprocessor in the UUT and serves both as an interface to allow the Troubleshooter access to components on the UUT and as an emulator of the UUT’s microprocessor. In normal Troubleshooter/Pod operation, the Pod adapts the general-purpose architecture of the Troubleshooter to the specific pin layout of the 80186 microprocessor. This allows the Troubleshooter to exercise each of the microprocessor’s signals and provides complete access to devices on the UUT that are connected to the microprocessor’s bus, while, at the same time, monitoring activity on the UUT. In the RUN UUT mode, the Pod’s microprocessor is connected to the UUT (through buffers) to serve as a substitute microprocessor. It can be configured to have the same structure of interrupts, chip selects, timers, and DMA control as the UUT’s microprocessor.
