Industrial RS485 WiFi Bridge
The SMUGDESK Elfin-EW11A-0 is a compact device server that converts RS485 serial signals to WiFi for industrial automation. It integrates Modbus TCP and TCP/IP stacks to translate Modbus RTU data into network packets. The complete kit includes an external antenna and mounting accessories for immediate deployment. Designed for PLCs, sensors and transmitters in factory or agricultural monitoring.
460800bps Serial Rate
The module supports serial communication up to 460800bps, enabling high-speed data transfer from legacy RS485 equipment. Built-in isolation protection and a wide 5-36V DC input ensure stable operation in electrically noisy environments. It complies with 802.11b/g/n wireless standards and offers STA, AP and STA+AP modes. TLS encryption secures data across the wireless link.
For Modbus RTU Upgrades
This unit suits engineers adding wireless connectivity to existing Modbus RS485 networks without rewiring. Buyers needing Ethernet cabling, cellular backup or multi-port serial aggregation should consider other form factors. The web interface and SmartLink simplify setup for integrators familiar with industrial protocols. It is not a general-purpose WiFi access point or router.

Questions about this item
How does the 460800bps serial rate perform when the unit is installed in a real machine?
The hardware supports serial communication up to 460800 bps, so RS485 devices such as PLCs or sensors can stream data at that speed across the WiFi link without an internal bottleneck.
What WiFi standard does the module use and what practical limit does it impose?
It complies with the 802.11b/g/n standard, so the wireless link is limited to the throughput and range of that specification when converting serial traffic to network packets.
What does the device need to fit and mount in a cabinet or panel?
The whole set ships with installation accessories and a wide 5-36V DC input, letting you secure the compact module and power it from common industrial supplies without extra parts.
