Introduction
About this document
This document describes how to connect ASUS-PE200U-FaceRecognition to Azure IoT Hub using the
Azure IoT Explorer with certified device application and device models.
IoT Plug and Play certified device simplifies the process of building devices without custom device
code. Using Solution builders can integrated quickly using the certified IoT Plug and Play enabled
device based on Azure IoT Central as well as third-party solutions.
This getting started guide provides step by step instruction on getting the device provisioned to
Azure IoT Hub using Device Provisioning Service (DPS) and using Azure IoT Explorer to interact with
device's capabilities.
ASUS PE200U is an Intelligent Edge Computer with a high-quality, TCO-optimized solution for AIoT
computing. PE200U includes up to 6 COM ports(2 x RS-232/422/485) and supports dual display
configuration by multiple interfaces: HDMI/DP and integrated CPU.
ASUS-PE200U-FaceRecognition has built-in a facial recognition SW in UWP UI Interface, user can key-
in their azure connection information or optimize some configuration by the UI interface. Users can
obtain the result of the recognition and access control information.
Prerequisites
You should have the following items ready before beginning the process:

Azure Account
Azure IoT Hub Instance
Azure IoT Hub Device Provisioning Service
Azure IoT Public Model Repository
Prepare the Device.
Hardware Environmental setup
Prepare ASUS-PE200U-FaceRecognition, USB Camera.
Connect the power adapter, HDMI, USB Camera with ASUS-PE200U-FaceRecognition.
Power on the ASUS-PE200U-FaceRecognition
Connect to the network.
Software Environmental setup
The UWP app and other software for face recognition have been preinstalled on the platform, it
will start as soon as the device is turned on.
Prepare IoT Hub and DPS configuration
Please refer to this tutorial to complete the following procedures :
1. Use Azure commands or Azure portal to create a Resource Group、an Iot Hub and a Device
Provisioning Service
2. To link the DPS instance to your IoT hub
3. To create your device by individual device enrollment in your DPS instance.
4. Make a note of the DPS information (DPS endpoint/Registration ID/ID Scope/Symmetric key).

5. Set the DPS information got from the former step to the UWP app.
Integration with Azure IoT Explorer
Connect to your IoT hub
The first time you run Azure IoT explorer, you're prompted for your IoT hub's connection string.
After you add the connection string, select Connect.
View devices
After the tool connects to your IoT hub, it displays the Devices list page that lists the device
identities registered with your IoT hub. You can select any entry in the list to see more
information.

Commands

Telemetry
Press the device name and choose the Telemetry Page. Press Start and wait a momnent. You will see
the telemetry data on the screen.
Connect to Azure IoT Central
1. Create an application
Please refer to this tutorial to create a "Custom application" template.
2. Create a device template from the device catalog
Please refer to this tutorial to create the ASUS-PE200U-FaceRecognition device template.
3. Add a device
Add a new device under ASUS-PE200U-FaceRecognition device template. Make a note of the device
ID.
4. Get connection information
ID scope : In your IoT Central application, navigate to Administration > Device Connection. Make
a note of the ID scope value.
Group primary key : In your IoT Central application, navigate to Administration > Device
Connection > SAS-IoT-Devices. Make a note of the shared access signature Primary key value.

Use the Cloud Shell to generate a device specific key from the group SAS key you just retrieved using
the Azure CLI.
az extension add --name azure-iot
az iot central device compute-device-key --device-id --pk
Make a note of the generated device key, and the ID scope for this application and set it from the
UWP app.
