Loosen the screw on the underside of the bottom clamp.

Work the four clamp posts of the bottom clamp through holes in the
5
target system PC board. Slide the clamp on the probe end of the PC
board back, then work the four clamp posts on through the
preprocessor PC board.

Securing the Preprocessor Connection
Move the top sliding clamp forward on the probe end until it holds
6
the clamp posts of the bottom clamp.
Tighten the screw on the underside of the bottom clamp until it is
7
snug (80 inch-ounces of torque). If the screw is too loose, the
preprocessor will not make good contact with the microprocessor
pins. If the screw is too tight, it may damage the interface connector.
Insert the heat sink into the rectangular opening on top of the
8
preprocessor interface. Select an orientation that does not interfere
with the target system. Tighten the two screws until the heat sink is
snug. Do not overtighten.
Connect the heat sink to a +12 Volt power source. The black wire is
9
ground, and the yellow wire is positive. To protect your target
system and the preprocessor interface, ensure the fan is running
whenever the target system is powered.
