Your Bridge for Serial, Ethernet & WiFi Connectivity
Looking to modernise legacy serial-based equipment by adding Ethernet and WiFi access? A 2 LAN port serial to 1 port WiFi converter enables your RS232 or RS485 devices to communicate across multiple network standards, opening new possibilities for remote monitoring, data acquisition, and industrial automation. Communica, South Africa's trusted supplier since 1977, brings a wide selection of serial device networking solutions with guaranteed local stock and expert support for makers, engineers, and procurement teams.
What Does a 2 LAN Port Serial to WiFi Converter Offer?
These versatile converters integrate your legacy serial devices directly into Ethernet (LAN) and wireless (WiFi) networks. By supporting two independent LAN ports alongside a single WiFi interface, they provide seamless redundancy or dual subnetwork bridges. Typical features include:
- RS232/RS485 serial interface (configurable)
- Two 10/100M LAN ports for daisy-chaining or subnetwork segmentation
- 802.11b/g/n WiFi with security protocols (WPA/WPA2)
- Web-based configuration via browser
- Modbus TCP/RTU bridging, virtual COM port, or socket server
Typical applications in South Africa include PLC/SCADA integration, IoT gateways for sensors and instrument clusters, point-of-sale upgrades, and remote energy monitoring in distributed facilities.
Technical Specifications & Feature Comparison
| Feature | Spec (Typical Range) | Notes |
|---|---|---|
| LAN Ports | 2 x RJ45, 10/100M | Supports pass-through or subnet bridging |
| WiFi Standard | 802.11b/g/n (2.4GHz) | Configurable STA/AP mode, typical ~20-100m range |
| Serial Interface | RS232/RS485, DB9 or terminal block | Set via jumpers/software; ESD protection |
| Protocols | TCP/IP, UDP, HTTP, Modbus TCP/RTU | Flexible for industrial and IT integration |
For advanced projects, some units support Modbus gateway/bridge, MQTT, SNMP, or custom firmware. Always confirm compatibility with your end application and project requirements before purchase.

Selection Guidance for South African Applications
When shortlisting a 2 LAN port serial to 1 port WiFi converter, consider these factors to best match South African technical and compliance needs:
- Network environment: Static IP vs DHCP, subnetting, and firewall permissions for sites/local authorities
- Electrical standards: Acceptable mains input (typically 9-36VDC) and accessory availability (Communica stocks suitable PSUs)
- Operating temperature: Many industrial sites in SA experience wide temperature ranges-check datasheets for -20 degreesC to +60 degreesC if needed
- Firmware support: For ongoing IT/admin scripting, does the device support remote upgrades or JSON/Modbus diagnostics?
Example: Integrating a Serial Energy Meter to a LAN/WiFi Network
1. Connect the utility meter's RS485 terminals to the converter's serial block.
2. Patch LAN1 to the plant office's switch (internal monitoring), and LAN2 to a guest/maintenance network.
3. Configure WiFi as an AP for temporary field engineer access.
4. Use the converter's built-in web server for setup (set baud rate, parity, and protocol mode).
5. Deploy a SCADA or Modbus polling tool to verify data flow from the LAN/WiFi clients.
Installation & Troubleshooting
- Verify supply voltage and polarity-avoid damage by cross-checking with the user manual before powering up.
- Check serial line protocol: Both ends (meter/device and converter) must use matching parameters (baud, parity, stop bits).
- For connectivity issues, isolate LAN, WiFi, and serial separately. Use ping/traceroute for network, and a serial console (e.g., RealTerm) for RS232/RS485 debugging.
- Always update firmware to the latest vendor release as per included documentation.
Communica's technical team can assist with basic setup if required. For large facility rollouts, factor in lead times for higher quantity orders-check live stock status or request a quote online.
