Industrial RS485-to-WiFi gateway
The SMUGDESK Elfin-EW11A-0 converts RS485 serial signals into WiFi or Ethernet data for IoT equipment. It bridges PLCs, sensors and instruments to a LAN or wireless network with bidirectional transparent transmission. The module includes a complete TCP/IP stack and supports Modbus TCP, TCP Server, TCP Client, UDP and Telnet protocols. A built-in web server enables remote configuration and firmware OTA upgrades.
Dual-interface networking flexibility
One RJ45 Ethernet port and an external WiFi antenna provide STA, AP and AP+STA operating modes for diverse topologies. The wide DC 536V input range suits varied industrial power environments. Its compact mini form factor saves cabinet space and mounts on a DIN rail using the supplied bracket. The full package includes antenna, connection cable and mounting hardware for immediate deployment.
Suited for Modbus automation integrators
Engineers adding wireless connectivity to existing RS485 field devices will find the protocol conversion and remote management valuable. Buyers needing more than a single serial port or a different physical interface should consider other device-server models. Those without Modbus TCP requirements may not use the full feature set.

Questions about this item
What is the widest DC voltage the Elfin-EW11A-0 can accept without an external regulator?
The module operates on a wide DC 536V input range, so it connects directly to most industrial power supplies without extra conditioning.
How hot does the unit get when it runs continuously inside a closed cabinet?
The compact mini form factor is designed for DIN-rail mounting in control cabinets; its low power draw keeps temperature rise minimal during all-day operation.
Which serial interface must my existing equipment provide for this server to work?
Your device needs an RS485 port; the server converts that signal to WiFi or Ethernet using Modbus TCP, TCP Server/Client, UDP or Telnet.
