Add hardware watch dog, makes more stable. Supports free framing and automatic framing on the serial port, for higher forwarding efficiency. - Support websocket and realize the timing communication for serial port and web page. Support web page, serial/network AT command to conFigure parameters. Support one key (press the reload button for more than 5 seconds) to restore factory settings. Long distance communication: two serial server can transport for 150m (Test conditions: open line of sight, two WIFI serial servers self-networking, 57600 baud rate, no packet loss during transmission) - Rail-mount Serial Server: Industrial Rail-mount Support, Easy to Install, Compact Size, Cost-effective. Support Transparent Transmission Mode: Supports TCP Server / TCP Client / UDP Server / UDP Client. Serial Command Mode: The user sends data to the server according to the protocol. Send data to different servers without restarting. - Support HTTPD Client Mode: After the user has set the HTTP header through AT commands or web page, the module can send data to the HTTP server, or obtain data from the HTTP server. Modbus Gateway support: Support Modbus TCP and Modbus RTU interconversion mode. AT command mode: The user can query the current status of the module, or set related parameters, by sending AT commands. - Support MQTT function: Devices can subscribe to other MQTT client messages, and can publish topic information to the server. Supports subscription of 6 messages and publication of 6 topics, wider range of use and more applicable scenarios. Users can view device-related information through terminal devices or cloud platforms. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BJL7QCS4 | | Box Contents | RS485 TO WIFI/ETH, Antenna | | Brand Name | Waveshare | | Color | RS485 to WiFi/Ethernet | | Compatible Devices | Desktop | | Country of Origin | USA | | Customer Reviews | 3.2 3.2 out of 5 stars (4) | | Data Transfer Rate | 57600 Megabits Per Second | | Hardware Interface | Ethernet | | Item Dimensions L x W x H | 11L x 6.5W x 2.8H Centimeters | | Manufacturer | Waveshare | | Manufacturer Part Number | RS485 To W+E Server-A | | Model Number | RS485 To W+E Server-A | | Number of Items | 1 | | Number of Packs | 1 | ## Product Details - **Brand:** Waveshare - **Colour:** RS485 to WiFi/Ethernet - **Compatible Devices:** Desktop - **Data Transfer Rate:** 57600 Megabits Per Second - **Hardware Interface:** Ethernet - **Manufacturer:** Waveshare - **Number of Items:** 1 - **Number of Packs:** 1 - **Product Dimensions:** 11L x 6.5W x 2.8H Centimeters ## Images ![RS485 to WiFi/Ethernet Module, Rail-Mount Serial Server, Modbus MQTT Gateway, Support 802.11b/g/n Wireless Standards, Support RS485 to WiFi, RS485 to Ethernet, Ethernet to WiFi, etc. - Image 1](https://m.media-amazon.com/images/I/41q0bAK6HrL.jpg) ![RS485 to WiFi/Ethernet Module, Rail-Mount Serial Server, Modbus MQTT Gateway, Support 802.11b/g/n Wireless Standards, Support RS485 to WiFi, RS485 to Ethernet, Ethernet to WiFi, etc. - Image 2](https://m.media-amazon.com/images/I/41LF3dQ6EVL.jpg) ![RS485 to WiFi/Ethernet Module, Rail-Mount Serial Server, Modbus MQTT Gateway, Support 802.11b/g/n Wireless Standards, Support RS485 to WiFi, RS485 to Ethernet, Ethernet to WiFi, etc. - Image 3](https://m.media-amazon.com/images/I/51i1-TNMG6L.jpg) ![RS485 to WiFi/Ethernet Module, Rail-Mount Serial Server, Modbus MQTT Gateway, Support 802.11b/g/n Wireless Standards, Support RS485 to WiFi, RS485 to Ethernet, Ethernet to WiFi, etc. - Image 4](https://m.media-amazon.com/images/I/41X6YfyGxUL.jpg) ![RS485 to WiFi/Ethernet Module, Rail-Mount Serial Server, Modbus MQTT Gateway, Support 802.11b/g/n Wireless Standards, Support RS485 to WiFi, RS485 to Ethernet, Ethernet to WiFi, etc. - Image 5](https://m.media-amazon.com/images/I/41oWwqTWrtL.jpg) ## Available Options This product comes in different **Color** options. ## Frequently Bought Together - Industrial Serial Server RS485 to RJ45 Ethernet Module with POE Function, Modbus MQTT Gateway,TCP/IP to Serial, Bi-Directional Transparent Data Transmission Between RS485 and Ethernet - waveshare Ethernet Industrial Serial Server RS485 to RJ45 Ethernet Module, TCP/IP to Serial, Support Rail-Mount/Modbus Gateway, TCP Server/TCP Client/UDP Mode/UDP Multicast Multi Communication Modes - USB to RS485 Converter Industrial Adapter Original FT232RL and SP485EEN Fast Communication Embedded Protection Circuits Resettable Fuse ESD Protection --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.il/products/623334793-rs485-to-wifi-ethernet-module-rail-mount-serial-server-modbus](https://www.desertcart.co.il/products/623334793-rs485-to-wifi-ethernet-module-rail-mount-serial-server-modbus) --- *Product available on Desertcart Israel* *Store origin: IL* *Last updated: 2026-10-19*
