The diagram above shows the adapter for the Palm Development Platform (Hurricane) or the Motorola
Development Platform. As with the other adapters, J2 mates with the “Generic CPU” connector located
on the back of the Evaluation board. Connector U4 mates with the 96-pin female DIN connector on the
Palm Hurricane Platform. Alternately, connector U6 can be used to connect to the Motorola
Development Platform. These connectors are keyed so cannot be installed incorrectly. J1 selects which
IRQ the MQ-1168 will connect to on the platform. Setting 1-2 selects IRQ2 while 2-3 selects IRQ3. The
Evaluation board requires 3.3V and 5V power from the adapter board. The Palm/Motorola adapter passes
the 3.3V power supplied on the platform connector but does not provide 5V. Connector JP1 is used to
provide 5V and can be connected to an external source. A wire with a mating female 0.25” square
connector can be attached to the 5V supply which does not go to the bus but is available on the platform.
The diagram below shows how the Evaluation board, adapter board and Palm or Mororola platforms are
connected. Care should be taken to line up the pins correctly, especially A1/B1/C1.
