Hardware Installation

1. SIM Card Installation

Remove the SIM card cover to insert the SIM cards into the device, then screw up the cover.

2. Antenna Installation

Rotate the antenna into the antenna connector accordingly.

3. Terminal Block Installation

Insert the 6PIN and 8PIN terminal blocks into the interfaces connector, then connect the devices or sensors to the gateway with wires via corresponding interfaces (e.g., RS232/RS485, DIDO).

4. Power Supply Installation

Insert the power supply cord into the corresponding terminal block if needed, then insert the terminal block into the power connector.

5. DIN Rail Mounting

Use 2 M3 screws to fix the DIN rail to the device, then hang the DIN rail on the mounting bracket.

6. Grounding the Device

Grounding will help to prevent the noise effect due to electromagnetic interference (EMI). Connect the device to the site ground wire by the grounding screw before powering on.

Login to the Device

1. Connect to the Gateway

Connect the gateway's Ethernet port to a PC with a standard Ethernet cable.

2. Configure PC Network Settings

Before logging in, manually configure the PC with a static IP address on the same subnet as the gateway address. For example, set the IP address to 192.168.0.2 and the Subnet mask to 255.255.255.0.

3. Access Web Interface

To enter the gateway's web interface, type http://192.168.0.1 into the URL field of your Internet browser.

4. Authentication

Use login information shown in the product label when prompted for authentication.

5. Navigate the Interface

After logging in, the home page of the web interface is displayed. You can view system information and perform configuration on the device.

6. Configure APN Settings

The automatic APN selection is ON by default. If you need to specify your own APN, please go to the menu Interface > Cellular > Advanced Cellular Setting > General Settings to finish the specific setting.

7. Further Configuration

For more configuration details, please refer to the RT104_SM_RobustOS Pro Software Manual.
