Reliable 2 LAN Port Serial to 1 Port WiFi Converter - Affordable Options at Communica

Connect Serial Devices to Networks - Cost-Efficiently

Legacy industrial, lab, and building control devices often use RS232 or RS485 serial interfaces. Modernising their connectivity with a 2 LAN port serial to 1 port WiFi converter allows for LAN redundancy, flexible wiring or bridging status equipment to your wireless infrastructure. Communica offers a curated selection of such converters for South African engineering teams, installers, and tinkerers at cost-effective prices.

Key Features & Application Scenarios

• Connects serial (RS232/RS485) equipment to Ethernet and WiFi networks simultaneously.
• Supports up to two LAN ports - ideal for failover, split-site or dual-segment installation.
• Enables remote access, cloud logging, and legacy equipment monitoring over IP.
• Typical use cases: industrial PLCs, CNCs, access control, energy meters, and university labs.

Comparison at a Glance

All models above can be found or requested through Communica, with alternatives available for custom requirements. These units are powered via DC adapter (typically 5-12V, not usually supplied) - ensure you select the correct power supply for your installation.

Advantages When Buying Locally from Communica

• Immediate stock in South Africa - Samrand warehouse and regional branches
• Technical advice for serial wiring, pinout adapters, and network configuration

Need a compatible DB9 cable, terminal block adapter, or power supply? Communica's accessories include ready-made cables, crimp tools, and DIN-rail mount kits for quick deployment.

Specification Callouts & Selection Guidance

• Serial Standards: Confirm RS232, RS485, or RS422 compatibility according to your device port.
• LAN Speeds: Most units support 10/100Mbps; check your network environment for maximum bandwidth needs.
• WiFi Security: WPA2 is typical; WPA3 is uncommon in industrial models.
• Operating Voltage: Verify if you need 5V, 9V, or 12V DC input - double-check plug polarity and size.
• Configuration: Web interfaces or dedicated Windows tools for IP setup, baud rate selection, and protocol (TCP server/client, UDP, Modbus-TCP bridging).

Typical Installation Example

Suppose you have a legacy access control panel at a remote facility, requiring serial monitoring and remote firmware updates. Installing a 2 LAN port serial to WiFi converter enables the panel to be reachable over both Ethernet segments (for redundancy) or over WiFi, with seamless failover and status logging to your server in Johannesburg.
