Gateway Installation

Note: It is not necessary to disassemble the Gateway shell during installation.

Installation Direction

Note: The front view of the product is shown in the picture above. GPS and 4G antenna interface to the right, WiFi antenna interface down. During the installation process, please ensure that the product orientation is consistent with the above figure for correct installation.

Backplane Installation

• Flip the gateway to the direction shown in the figure and confirm that the backplane is tightly connected to the Gateway.
• Align the screw with the screw hole and use a screwdriver to turn it clockwise until the screw cannot turn.

Network cable installation

• Thread the waterproof plug into the network cable from right to left in the following order, and assemble parts 1, 2, 3 and 4 tightly
• Insert one end of the network cable crystal head into the Gateway POE interface
• Move the assembled waterproof plug part to the direction of the Crystal Head, and screw it on the POE interface to ensure that the assembled waterproof plug is tightly connected with the POE interface.

SIM card installation

• Unscrewing the waterproof cover on the SIM interface
• Keep the SIM card metal patch position towards the TYPE-C interface
• Insert the SIM card into the card slot and tighten the waterproof cover.

Power connection

• OUT port connection gateway POE interface (power supply)
• The IN port is connected to a switch or router (network supply). If there is 4G, there is no need to connect the IN interface.

FRP antenna installation

• [x] Connect the LoRa antenna to the Gateway RF interface

Note: This step is required for the optional lora antenna.

Gateway fixed

Wall-mounted fixed

• Install with the Gateway face up (Figure 1)
• Four holes corresponding to the holes of the back plate bracket are made in the wall, and then the expansion bolts are driven in (the positions of the four holes of the back plate bracket can be marked on the wall first)
• Pass the expansion screw through the back bracket and screw in the expansion screw with a tool.

Holding Rod fixing

• Install with the Gateway face up (Figure 2)
• Confirm that the pole diameter is between 30mm-52mm
• Combine the holding Rod clamps according to the position shown in the figure, and tighten the screws.

Precautions

Waterproof protection

• Use insulating tape or waterproof material to wrap and seal the connection to ensure that it is not penetrated by moisture and moisture.
• Pay special attention to areas where moisture can easily enter, such as outdoor installations or areas exposed to rain or high humidity.
• The insulating tape is tightly wrapped around the connection, completely covered, and forms a waterproof barrier.
• Check the waterproof condition regularly, and re-coat or replace the insulating tape as needed to maintain effective protection.
• Ensure that all connections and cables are properly sealed and protected to prevent moisture damage and maintain the integrity of the installation.

Gateway waterproof

• Ensure all cable entry points and connectors on the Gateway are properly sealed following the installation steps
• Pay particular attention to areas where moisture may enter, such as cable connections, antenna interfaces, and power input ports.
• Apply a layer of waterproof material around the cable entry point and connector, completely covering to prevent moisture penetration.
• Check the waterproof condition regularly, and re-coat or replace the waterproof material as needed to maintain effective protection.

POE adapter waterproof installation

• Cose a suitable location to install the POE Adapter, making sure it is away from direct water sources or areas that may splash water.
• Make sure that the POE Adapter is installed vertically with the connection port down to prevent water from entering.
• Use a waterproof material, such as insulating tape or waterproof casing, to cover and seal the connection of the POE Adapter.
• Pay attention to the entry points of the cables and make sure they are properly sealed to prevent water from entering.
• Check waterproofing measures regularly and re-coat or replace any damaged or aged materials.

Please note that waterproofing requirements may vary depending on the specific environment and installation conditions. To ensure effective waterproofing, follow best practices and consult a professional if needed.
