## Long description

The D-Link DOM-550-GSO 5G IIoT Gateway with Gigabit Ethernet, Wi-Fi 5, 4G and 5G Cellular Support, and RS-232/485 Serial Interface is a high-performance industrial networking device engineered for demanding Internet of Things applications. Built into a durable zinc-plated steel case, this black cellular network gateway delivers reliable machine-to-machine communication, remote device management, and high-speed data transmission in harsh environments with operating temperatures ranging from -30 to 70°C. It features robust 4G and 5G cellular network support including Sub6 NSA and SA standards with dual SIM slots, dual-band Wi-Fi 5 connectivity, and fast Gigabit Ethernet LAN interfaces.
Advantages
This industrial gateway provides exceptional reliability through dual SIM slots with auto-failover redundancy, ensuring continuous cellular WAN connectivity even if the primary network fails. Its corrosion-resistant zinc-plated steel housing and wide voltage range input from DC 9 to 36V make it suitable for challenging deployment locations. The inclusion of an RS-232/485 serial port and Modbus TCP/RTU/ASCII protocol compatibility allows for seamless integration of legacy industrial equipment into modern IT and OT infrastructures.
Suitable for
Industrial automation and machine-to-machine communication
Remote telemetry and sensor data collection
Connecting legacy serial devices to modern IP networks
Cellular WAN failover backup for critical infrastructure
Smart factory IT and OT network convergence
When it may not be suitable
This device is specifically designed for industrial IIoT and M2M applications and is not intended for standard residential home networking or basic office internet sharing. It may also exceed requirements for simple environments that do not require wide temperature tolerance, DIN-rail mounting, or specialized serial interfaces.
Key specifications
Cellular network support: 4G LTE, 5G Sub6 NSA and SA with dual SIM slots
Ethernet LAN: 3 x Gigabit Ethernet ports supporting 10, 100, 1000 Mbit/s
Wi-Fi standards: 802.11a/b/g, Wi-Fi 4, Wi-Fi 5 AC1200
Serial interface: 1 x RS-232 or RS-485 port
Digital I/O: 2 x Digital Input, 2 x Digital Output
Expansion and storage: 1 x USB 2.0, 1 x MicroSD card slot
Enclosure: Corrosion-resistant zinc-plated steel, DIN-rail mountable
Operating temperature: -30 to 70°C
Power input: Wide voltage range DC 9-36V
How to use
Mount the gateway securely onto a DIN-rail within your industrial enclosure and connect the necessary external antennas to the SMA connectors. Insert one or two active nano-SIM cards into the dual SIM slots to establish cellular connectivity. Connect your wired network devices to the Gigabit Ethernet ports, or attach legacy sensors and controllers using the RS-232/485 serial interface and digital I/O terminals. Power the unit using a compatible DC 9-36V power source, then access the web-based management interface to configure network settings, Modbus protocols, and event-trigger notifications.
What to consider before purchase
Verify that your local mobile network operators provide compatible 4G LTE or 5G Sub6 coverage in the deployment area
Check whether your equipment requires RS-232, RS-485, or digital I/O connections
Confirm that the power supply voltage matches the wide DC 9-36V specification of the gateway
Ensure the operating environment stays within the -30 to 70°C temperature range
Usage recommendations
For optimal cellular performance, install external antennas in a position with clear signal reception and away from heavy metallic obstructions. Utilize the dual-SIM failover feature with carriers from different networks to maximize uptime in critical industrial applications.
