Figure 25. Example of Wiring for Single Port Connection between Maestro and MI-3040
The number of GPIO ports connected to the MI-3040 will vary according to
system requirements; the maximum number is 16. Connections can be
made in any order since the connectors are configured in software.
For pinouts of the GPIO connector, see Table 9 on page 95 . For a diagram of
the GPIO port circuitry, see page 96 .
For pinouts of the MI-3040, and a description of the MI-3040 hardware,
refer to the Jupiter manual.
