2 LAN Port Serial to 1 Port WiFi Converter - Distributor in South Africa

Advanced Serial-to-WiFi Connectivity - Now with 2 LAN Ports

Integrating legacy serial equipment into modern Ethernet and wireless networks is essential in industrial, building automation, and institutional environments. A 2 LAN port serial to 1 port WiFi converter enables seamless bridging between RS232/RS485 serial devices, dual wired networks, and wireless infrastructure - ideal for remote device management, redundancy, or segment bridging in South African installations.

Communica supplies a variety of industrial-rated serial server converters with dual LAN ports and powerful serial-to-WiFi translation. These units are compatible with SCADA, PLC, security, and energy monitoring systems, supporting protocols such as Modbus TCP/IP, transparent serial tunneling, and easy network device discovery.

Why Choose Dual LAN Serial-WiFi Converters?

• Redundant Ethernet paths for failover or ring-topology resilience.
• Flexible deployment - bridge serial to WiFi, or dual-wired to serial, as needed.
• Field-configurable IP addressing, link speed, and wireless security (WPA2/PSK, enterprise).

Typical Applications

• Connecting PLCs and HMIs in distributed plants.
• SCADA remote telemetry integration via WiFi or dual LAN failover.
• Retrofit of serial-only control panels to IP-based access.
• Metering, POS, and security device networking in multi-building facilities.

Specs & Leading Features (Sample Table)

*Check product datasheet for PoE model availability.

Supported Protocols & Software

• TCP Server/Client, UDP, and transparent tunneling.
• Virtual COM support for Windows/Linux laptops and SCADA PCs.
• Compatible with most serial terminal software and custom field applications.

For South African organisations, these converters help bridge the digital divide between legacy infrastructure and modern, IP-centric SCADA or remote asset management. Leading stocked brands at Communica include USR IOT, Sealevel, and Aureon (subject to current inventory).

Selection Criteria for South African Buyers

• LAN Failover: If your application needs automatic switching or dual uplink, request models with proven LAN bonding or ring topology support.
• Serial Protocol: Choose RS232 for short cable runs, or RS485 for multi-drop, long-distance industrial setups.
• WiFi Security Levels: WPA2 (min.), SSID control, and MAC address filtering - crucial in enterprise and campus deployments.
• Mounting & Power: DIN-rail vs. panel mount; determine if you need wide-range DC input or PoE for your cabinet installation.

Example Configuration

A transport company in Gauteng implements a dual LAN serial-to-WiFi converter in each depot. They connect existing RS485 smart meters to their cloud-based dashboard via WiFi, with one LAN port connected to the site's office LAN and the other for remote field service access. Local pickup at Communica's Samrand warehouse reduced deployment time, aided by VAT invoicing for the enterprise client.

Troubleshooting Tips

• Verify all IP addresses are assigned to the correct VLAN/subnet for dual LAN operation.
• Ensure serial wiring matches your device (null modem or straight-through); test with a USB serial adapter if unsure.
• Use built-in diagnostics web pages to test WiFi and serial port status before field installation.
