Lantronix E214 LTE Cat 1 Industrial IoT Router with Edge Compute

The E214's two Ethernet ports are user-configurable via the web-based administration interface or CLI. You can assign one as a WAN port for internet uplink (e.g., connecting to a modem) and the other as a LAN port for local network devices. This is done in the network settings section, where you define the role, VLAN tagging, and firewall rules for each interface to match your network topology.

Insert active SIM cards from different carriers into SIM1 and SIM2. Within the router's web interface, navigate to the Cellular/WAN settings. Enable the 'Failover' or 'Backup' feature and set the primary SIM. The router will monitor the connection quality of the primary SIM and automatically switch to the secondary SIM if the signal is lost or degrades below a defined threshold, ensuring uninterrupted service.

Yes. The E214 includes native Modbus protocol support. Connect your Modbus RTU device (e.g., a sensor or PLC) to the RS232 or RS485 serial port. In the router's configuration, set up a serial-to-TCP bridge or use the built-in Percepxion edge agent to map the serial registers. The router will then expose the Modbus data as a Modbus TCP server on your network, allowing your central SCADA software to poll it directly over IP.

The E214 supports multiple VPN types. For an OpenVPN tunnel, generate certificates on your VPN server, then upload the client certificate, key, and CA file to the router via its web interface. Enter the server address and port. For IPsec, configure Phase 1 and Phase 2 parameters (encryption, hashing, DH group) and pre-shared keys to match your corporate gateway settings. The router's firewall rules must allow traffic to flow through the new VPN tunnel interface.

The E214 requires a DC power source between 8V and 32V. A regulated 12V or 24V DC supply is typical. Ensure the power adapter can provide sufficient current, especially if powering additional devices via the router's USB port. For installations in vehicles, use a stable DC-DC converter to protect against voltage spikes. The wide input range accommodates most industrial and vehicular power systems, but consistent voltage within spec ensures long-term reliability.
