USAGE
For basic operation, the Avnet SmartEdge IIoT Gateway requires a power connection along with internet access. A
mobile App can be used to connect the Gateway to the IoTConnect cloud solution, and create a new user account to
access it.

POWER INPUT
An external power supply is required (not provided)
Output rating: 12VDC to 24VDC (+/- 10%), 18W minimum, 24W recommended, LPS (Limited Power Source)
Use 16-22AWG power supply wiring, stripped back 4-5mm, twisted & optionally tinned
Find the black, 3 position terminal plug in the included parts kit
Insert the prepared wires into the terminal plug, observing proper location
An Earth GND wire is recommended

INTERFACES
USB 2.0
Two USB 2.0 High-Speed ports are available to accept devices and can provide 0.5A per port.
ETHERNET
Two 10/100 Ethernet peripherals are available. By default, both are configured the same and can accept connection to
the customers network. Some advanced topologies could be configured by the customer (bridged, router, etc).
RESET BUTTON
A pin hole reset button (labeled RST) is located next to the HDMI port. A paperclip can be used to activate it.
Short press (less than 5 seconds) initiates a reboot
Long press (between 5 and 30 seconds) re-enters Configuration state for IoTConnect Cloud Enrollment (section 3.4)
Very long press (greater than 30 seconds) performs a Factory Reset
HDMI
An HDMI monitor can be used for console display. It should be connected at boot to enable the proper output.
ONBOARD DIGITAL I/O
The digital inputs and outputs are available as /sys/class/gpio/gpio200 thru gpio207. GPIO200/202/204/206 are
inputs and GPIO201/203/205/207 are outputs. See the schematic in the appendix for detailed connections. GPIOs
must be exported in your application to use them. If they are used in the SDK (IoTConnectSDK.conf) then they are
exported automatically.
