Installation and Startup
Rev 4 March 2019 25 41110030
• Pin 1 (Power) —Use the red wire in the DC cable to connect Pin 1 to the
power source.
• Pin 2 (Ground)—Use the black wire in the DC cable to connect Pin 2 to
ground. See also Step 2—Mount and Ground the FX30 Chassis on page 12.
• Pin 3 (On/Off)—Connected to power
Pin 3 must be connected.
• I/O 1—configured for digital input
• Optional—I/O 2 and I/O 3
Note: See Table D-1, FX30 Hardware Feature to Linux Interface Mapping, on page 74 for
the GPIO and Linux interface mapping of pin 3, I/O 1, I/O 2, and I/O 3.
I/O Configuration
The FX30 power connector has three pins you can use for I/O configuration:
• I/O 1—Digital input only; allows wakeup from ultra low power mode
• I/O 2—Digital and analog input; allows wakeup from ultra low power mode
• I/O 3—Digital input and digital output
Note: See Table D-1, FX30 Hardware Feature to Linux Interface Mapping, on page 74 for
the GPIO and Linux interface mapping of the I/O pins.
Note: The IoT Expansion Card has four GPIO pins that you can program using Legato.
For details, refer to the IoT Expansion Card Design Specification.
I/O Pins
You can use the I/O pins as:
• Digital inputs
(See Table 2-2 on page 26 and Figure 2-19 on page 26.)
• High side pull-ups/dry contact switch inputs
(See Figure 2-20 on page 27.)
• Analog inputs
(See Table 2-3 on page 28 and Figure 2-22 on page 28.)
• Low side current sinks
(See Figure 2-23 on page 28.)
• Digital outputs/open drains
(See Table 2-4 on page 29 and Figure 2-24 on page 29.)
Note: The I/O pin functionality is programmable in Legato applications.
