Connecting the probe adapter to the target system
The CPU microcontrollers supported by the HP E2480A Preprocessor
Interface come in a variety of QFP packages. The QFP probe adapter
assemblies allow the preprocessor interface to be connected to the target
system without removing the microcontroller from the target system. Refer
to the Probe Adapter Users Guide (included with your HP E81xxA order) for
information on attaching the QFP Probe Adapter to your target system.
The illustrations on the following pages show the allowable rotations for the
different QFP probe adapters when used with the HP E2480A. Note that the
orientation (rotation) of the preprocessor with respect to the probe adapter
depends on the orientation (rotation) of the probe adapter with respect to
the target system. To ensure that you do not have mechanical interference
between the preprocessor interface and the target system, use the rotation
diagrams on the following pages, and the instructions in "To connect the
preprocessor interface to the probe adapter," to determine the desired
orientation before you connect the probe adapter to the target system.
CAUTION
Serious damage to the target system or preprocessor interface can result
from incorrect connection. Note the position of pin 1 (or pin A1) on the
target system, transition board, and the preprocessor interface prior to
making any connection. Also, take care to align the preprocessor interface
connector with the pins on the probe adapter assembly so that all pins are
making contact.
CAUTION
To prevent equipment damage, remove power from all system components
before making attachments.
