33、00 Interface Pod (hereafter referred to as the Pod) interfaces any Fluke YOOO reries Micro-Sqstcmlrouhleshooter(hereafterreferred toas theTroubleshooter) to equipment using one of the LX000 family of microprocessors. The Troubleshooter scrviccs printed circuit hoards, instruments, and systems employ

34、ing microprocessors. I hc YOOOA-ZXOOO Interface Pod adapts the general purpose architecture of the I;oubleshooter to the specific architecture of the Z8000 microprocessor family. The Pod adapts such micropl-ocessor-specific functions as pin layout. status/control functions, interrupt handling. timin

35、g, and memory and i/O addressing. I hc YOOOA-ZXOOO Intrrface Pod can accommodate all four members ofthe 28000 family: ZXOOI, %X002. ZXOO3. and 28004. An adapter is provided for use with the 40-pin 28002 and /X004 versions. A switch on the fod selects betweenSegmented Memory28001 and zxooz CIS1”“S.an

DESCRIPTION OF POD t-igurc I-I shows the communication between the Troubleshooter. the Pod, and the Unit- I:nder- lest (hereafter re

37、ferred to as the Ul!I). Cables connect the Pod to the I rouhlcshooter via a front,-panel connector and to the I:Ul through the microprocessor !Kkct. I he external features of the Pod is shown in Figure l-2 Intcrnal!y. the Pod consists of a pair of printed circuit board assemblies mounted within an i

41、收音机爱好者资料库 Ra d i o Fa n s .CN The .Troub!eshooter supplies operating power(+5V) for the Pod. The LJUT provides the external clock signal required by the Pod for operation. Using the UUT clock signal allows the Troubleshooter and Pod to function at the designed operating speed of the UUT (up to IO MH

42、z). I.ogic level detection circuits are provided on each line to the UUT. These circuits allow detection of bus shorts, stuck-high, or stuck-low conditions, and any bus drive conflict (two or more drivers attempting to drive the same bus line). Over-voltage protection circuits are also provided on e

43、ach line to the U UT These circuits guard against Pod damage which could result from the following: I.Incorrectly inserting the ribbon cable plug in the UUT microprocessor socket. 2. UUT faults which place potentially-damaging voltages on the UUT microprocessor socket. The over-voltage protection ci

44、rcuits guard against voltages of +12V to -7V on any one pin. Multiple faults, especially of long duration. may cause Pod damage. A power level sensing circuit constantly monitors the voltage level of the UUT power supply (+5V). If UUT power rises above or drops below an acceptable level the Pod noti

45、fies the Troubleshooter of the power fail condition. The 48-pin zero-insertion force Self Test Socket provided on the Pod enables the Troubleshooter to check Pod operation. The ribbon cable plug must be connected to the Self Test Socket during self test operation. The ribbon cable plug should also b

46、e inserted into this socket when the Pod is not in use to provide protection for the plug. 1-3.
