Overview: 2 LAN Port Serial to 1 Port WiFi Converters

Integrating legacy serial equipment with modern IP networks is a core challenge for engineers and industrial users. 2 LAN port serial to 1 port WiFi converters address this, acting as bridge devices that connect a serial (RS232/RS485) interface to both wired Ethernet (with dual LAN redundancy or switching) and wireless WiFi networks. This enables remote monitoring, management, or data acquisition using standard TCP/IP tools.

Typical Features & Applications

• 2x RJ45 LAN ports (for redundancy, failover, or network segmentation)
• 1x Serial port (RS232/485, DB9 or terminal block)
• WiFi client/AP operation (connect to WiFi networks or act as access point)
• Built-in protocol support: TCP Server/Client, UDP, Modbus TCP/RTU
• Industrial temperature and voltage tolerance
• DIN-rail or panel mountable for easy integration

Specification Snapshot

Choosing the Right Converter

• Network Configuration: Do you need LAN redundancy, segment bridging, or just a simple switch-through?
• Serial Support: Confirm if your device needs RS232, RS485, or both - some models auto-select.
• WiFi Mode: Choose between client (joins an existing network) or AP (creates its own network).
• DIN vs Panel Mount: Match the form factor for control cabinets or field installations.
• Industrial Ratings: For production sites, check power supply and temperature range align with local demands.

Compatibility, Installation, and Local Buying Tips

Installation Example: SCADA Serial Gateway

Suppose you are modernising a pump station in the Western Cape. Your legacy PLC communicates via RS485 but needs to be monitored over the site's LAN for plant SCADA, and remotely via WiFi for engineering staff. A 2 LAN port serial to 1 port WiFi converter enables this by acting as a transparent serial-to-IP bridge, with dual LAN ports for internal site switching and WiFi for wireless remote access. Here's a sample high-level wiring:

LAN1    LAN2         WiFi
 |       |           |
[SCADA]<->[Converter]<-------->[Engineer Tablet]
   |              |
 [PLC]-(RS485)----|

• Set LAN1 as the uplink and LAN2 as a switch-through to the next cabinet.
• Configure WiFi as a secure client to the plant wireless network.
• Serial port links to the PLC for Modbus or direct protocol bridging.

Brand Selection & SA Availability
