Pentium II Instrumented Mobile Module, ensuring that Pin 1 is
properly aligned (see illustration below).

Damage to the connectors on the target system and probe adapter can result
from incorrect connection. Note the position of Pin 1 of the 190-pin Mictor
connectors on the probe adapter and the Instrumented Mobile Module board
prior to making any connection. Take care to align the probe adapter
connector with the pins on the Instrumented Mobile Module board
connector so that all pins are making contact. Also, ensure that the probe
adapter is firmly seated in the 190-pin Mictor connector, and that the probe

adapter is parallel within ±4° with the Pentium II Instrumented Mobile

Module.
