Original Packing Included 1 x UT-890A USB to RS485 RS422 Converter (USB V2.0) 1 x Terminal block 1 x CD Driver Review: Excelente - Excelente Review: Solid device with FTDI interface, extras included - This product is really nice. Thanks to the FTDI USB interface, it just works with the Linux and Mac machines I tested it with without installing any special drivers (I didn't have access to Windows for testing). I did not test super fast speeds, but the device was solid for moderate speeds like 19.2K and 39.4K. It comes in really nice packaging. Something the product page does not say is that the package also includes a small DB-9 to screw-terminal breakout dongle, which is really helpful when you are running cable from here to there. That saves you the trouble of making a breakout, or paying $7-12 for one on-line. The complaints about no printed documentation included are somewhat legit. There is a mini-CD-ROM included in the package, but since the disk's small form factor won't fit in my CD drive, I have no idea what is on the disk. You can find documentation at the http://www.szutek.cn website, and searching for the product name, UT-890A. It is written in fairly good English, good enough to describe the important information like the product specs, pin-out of the adapter, and basic RS-422/485 network topology. I should also say that at the large organization where I work, we use these in experimental labs with great success. ## Features - 5ft Cable Length - Easily connect DB-9 serial devices to USB-equipped computers.

According to the manual, the dcx2496 also supports RS232. Unless you want to run multiple dcx2496 units from a single computer interface, I suggest getting a USB to RS232 converter, since it should plug right in to the dcx2496 IF (and only if) Behringer has used the commonly accepted method for wiring up an RS232 port. The RS485 port on the dcx2496 uses an RJ45 connector, so you would need another converter from DB9 (F) to RJ45, or you would need to wire up your own connector. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excelente *by N***A on October 17, 2023* Excelente ### ⭐⭐⭐⭐⭐ Solid device with FTDI interface, extras included *by C***T on May 9, 2015* This product is really nice.

Just make sure you use the enclosed CD with the latest Driver before you try to use the cable. For the price I would recommend it to anyone that requires communicating through their computer USB terminal. ## Frequently Bought Together - UTEK UT-890A 5ft 1-Port USB to RS-485/422 Serial Converter with ESD Protection - Waveshare USB to RS232 / RS485 / TTL Industrial Isolated Converter with Original FT232RL Embedded Protection Circuits and Aluminium Alloy Enclosure for Industrial Control Equipments - USB to RS485 Converter Industrial Adapter Original FT232RL and SP485EEN Fast Communication Embedded Protection Circuits Resettable Fuse ESD Protection --- ## 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/3977259-utek-ut-890a-5ft-1-port-usb-to-rs-485](https://www.desertcart.tn/products/3977259-utek-ut-890a-5ft-1-port-usb-to-rs-485) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-06-01*
