• 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 FX30S 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 3-10, WP8548 Radio Module Interface Mapping, on page 59 for the radio
module GPIO and Linux interface mapping of pin 3, I/O 1, I/O 2, and I/O 3.
I/O Configuration
The Sierra Wireless FX30S power connector has three pins you can use for I/O
configuration:
• I/O1—Digital input only; allows wakeup from ultra low power mode
• I/O2—Digital and analog input; allows wakeup from ultra low power mode
• I/O3—Digital input and digital output
Note: See Table 3-10, WP8548 Radio Module Interface Mapping, on page 59 for the radio
module 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 27 and Figure 2-19 on page 27.)
• High side pull-ups/dry contact switch inputs
(See
Figure 2-20 on page 28.)
