Notes:
1. The triangle symbol (
) denotes Pin 1 on connectors. See Q5 Processor Board Jumpers, LEDs, and Connectors for jumper
settings.
2. Do NOT remove the CN4 jumper. Removal of this jumper will cause the processor to not power up.
3. Although the Q5 processor board is the main controller, most of customer connections will be to the Interface board, as
shown later.
