1. Introduction
Overview
The AIG-301 Series advanced IIoT gateways are designed for Industrial IoT applications, especially for
distributed and unmanned sites in harsh operating environments. AIG-301 series has implemented Modbus
RTU/TCP master/client protocols which can help you to collect Modbus devices. Moreover, Azure IoT Edge
software is preloaded and seamlessly integrated with the AIG-301 Series to enable easy, reliable, yet secure
sensor-to-cloud connectivity for data acquisition and device management using the Azure Cloud solution.
With the use of the ThingsPro Proxy utility, the device provisioning process is easier than ever. Thanks to
the robust OTA function, you never have to worry about system failure during software upgrades. With the
Secure Boot function enabled, you can prevent malicious software injection during the bootup process.

2. Getting Started
Connecting the Power
Connect the power jack (in the package) to the DC terminal block (located on the top panel), and then
connect to a power line with range 12 to 48 VDC. It takes about 3 minutes for the system to boot up. Once
the system is ready, the Power LED will light up. All models support dual power inputs for redundancy.
Connecting Serial Devices
The AIG device supports connecting to Modbus serial devices. The serial port uses the DB9 male connector
and can be configured by software for the RS-232, RS-422, or RS-485 mode. The pin assignment of the port
is shown below:

Connecting to a Network
Connect one end of the Ethernet cable to the AIG’s 10/100/1000M Ethernet port and the other end of the
cable to the Ethernet network. The AIG will show a valid connection to the Ethernet by LAN1/LAN2
maintaining solid green/yellow color. For details on the behavior of the LEDs, refer to the AIG-301 Series
Quick Installation Guide.

System Settings—HTTP/HTTPS
To ensure the securely access web console of the device, we strongly recommend disabling HTTP and
enabling HTTPS. To do this, go to System Settings > HTTP/HTTPS.
To use the HTTPS console without a certificate warning appearing, you need to import a trusted certificate
issued by a third-party certificate authority. If there are no imported certificates, the AIG Series can
generate the “AIG Series Root CA for HTTPS” certificate instead.

Basic Settings
When you access the Modbus TCP setting page, you will first need to configure the basic settings.
Parameter
Value
Default
Description
Initial Delay
(ms)
0 to
30000 0
Some Modbus slaves may take more time to boot up than other devices.
In some environments, this may cause the entire system to suffer from
repeated exceptions during the initial bootup. After booting up, you can
force the AIG to wait some time before sending the first request
by setting
a value for this parameter.
Maximum
Retry 0 to 5 3
This is used to configure how many times AIG will retry to communicate
with the Modbus slave when the Modbus command times out.
Response
Timeout (ms)
10 to
120000 1000
You can configure a Modbus master to wait a certain amount of time for a
slave’s response. If no response is received within the configured time,
the AIG will disregard the request and continue operation.
