Designed for industrial environments, it enables seamless, high-speed communication between modern PCs and legacy RS-485/422 devices, supporting up to 32 devices in multipoint mode and compatible with a wide range of operating systems. ## Description As the PC industry growing, most of the low speed external ports are replaced by USB port. In industrial environment, lots of important equipments still adopt RS-485/422 interface design. With this, most of the users use USB to RS-485/422 converter to transmit the data between PC and RS-485/422 equipments. UT-850N is a universal USB to RS-485/422 converter. There is no need external power; it is compatible with USB and RS-485/422 standards. UT-850N enables to convert USB signal to balanced differential RS-485/422 signal. It provides each wire with surge protection; the tiny interelectrode capacitance ensures high speed transmission for RS-422/485 ports. RS-485/422 adopts DB9 female as connector; internal zero delay auto receiving and transmitting function, unique I/O circuit auto control data flow direction without any handshake signal (RTS, DTR) ; there is no need jumper wire setting for full duplex (RS-422) and half duplex (RS-485) mode, plug & play. All these ensure that it is compatible with all the communication software and interface hardware. UT-850N provides connection for point to point, point to multipoint communication. For point to multipoint mode, each converter is allowed to connect 32 sets RS-422 or RS-485 device with baud rate 300-921.6Kbps. ## Features - Standards: USBV1.1, RS-485/422 EIA ● USB Signal: VCC, DATA+, DATA-, GND, FG ● RS-485 Signal: T+, T-, GND ● RS-422 Signal: T+, T-, R+, R-, GND - Working mode: Asynchronous, point to point or point to multi-point, 2 wires half-duplex or 4 wires full-duplex ● Direction control: Adopts data flow direction auto control technology to distinguish and control the direction - Baud rate: 300-921.6Kbps auto-detect serial signal ● Loading capacity: Supports point to multi-point communication, allows to connect 32 sets RS-422 or RS-485 device ● Transmission distance: 5,000m(9,600bps) for RS-485/422, no more than 5m for USB - Port protection: Surge, ±15KV ESD protection ● Connector: USB-A male, DB9 male ● Transmission media: twisted-pair or shielded cable - Length: 1.5m ● Operating temperature: -20℃ to 75℃ ● Relative humidity: 5% to 95% ● Transmission distance: 0-1,200m（921,600bps-9,600bps） ● Supports Win Android/2000/2003/2008/2012/XP/Vista/7/8/8.1/10/CE/Mac/Linux ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07QWTPC6F | | Best Sellers Rank | #475 in Serial Adapters | | Brand | UOTEK | | Compatible Devices | PC | | Connector Type | Serial Adapter | | Finish | Matte | | Item Weight | 0.16 kg | | Manufacturer | UTEK | | Mfr Part Number | 850N | | Model Number | 850N | | Number of Items | 1 | | Number of Ports | 1 | | Package Quantity | 1 | | Power Plug Type | No Plug | | Unit Count | 1 Count | ## Product Details - **Brand:** UOTEK - **Compatible Devices:** PC - **Connector Type:** Serial Adapter - **Finish Type:** Matte - **Item Weight:** 0.16 kg ## Images ![UTEK UT-850N 1-Port USB to RS-485/422 Serial Converter with ESD Protection - Image 1](https://m.media-amazon.com/images/I/61GSryhc+pL.jpg) ## Frequently Bought Together - UTEK UT-850N 1-Port USB to RS-485/422 Serial Converter with ESD Protection - DTECH USB to RS422 RS485 Serial Port Converter Adapter Cable with FTDI Chip Supports Windows 11 10 8 7 XP Mac -1.5 Feet --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/153245821-utek-ut-850n-1-port-usb-to-rs-485-422](https://www.desertcart.tn/products/153245821-utek-ut-850n-1-port-usb-to-rs-485-422) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-26*
