At the conclusion o f the self-test (less than 4.9 seconds), the FA I L L E D should be
extinguished. A n illuminated FAIL LED is an indication of a module failure. I f this occurs,
the module should be removed from the VXlbus chassis, and examined for damage or
improper installation.
2.7 L O C A L BUS USAGE WITH 7064 BREADBOARD
The VXlbus has a provision for interconnecting adjacent cards through a local bus. The bus
consists of 12 lines which jumper card together. A card on the left of another will have
connections on the "C" side of P2 tied to the "A" side of P2 for the card to its right. (Refer
to the VXlbus specification for exact pinouts.)
2.8 I N S T A L L I N G THE VSD-1 SERIAL DEBUGGER
1. Remove the thirteen #4 x 1/4 inch and the three #2 x 3/16 inch screws
retaining the top cover of your breadboard module. Remove the cover
and set it aside.
2. Remove the EPROM located at Ul of the VXlbus interface hoard using
a PLCC extraction tool (i.e., Burndy P/N 855045). This EPROM must
be removed in order for the breadboard to function with a debugger
installed.
3. Remove the two #4 x 5/8 inch screws located between P100 and P102 of
the V X I interface board along with their two flat and two split lock
washers. Retain this hardware for use when the serial debugger assembly
is removed.
4. T h e serial debugger assembly is installed directly above the VXlbus
interface board. The two mounting spacers on the debugger assembly
should be aligned to the two mounting points where the screws that were
removed came from. Use the two #4 x 1 1/8 inch screws along with the
flat and split lock washers provided with the serial debugger to hold the
debugger in place.
5. I f the debugger assembly is correctly situated, its P1 connector will align
directly above the VXlbus interface's P100 connector. Install the short
ribbon cable assembly between these two connectors, taking care to align
them correctly.
