Prolific?** A: This cable with FTDI chip (FT232), the CD driver comes with the cable. And ,you can download the driver on FTDIchip Website too. (This one is another type DTECH USB to RS232 Cable which with Prolific chip: https://www.amazon.com/dp/B017CZ3FZ2 ) **Q: Will this work with a cisco switch?** A: Most Cisco switches use an RJ-45 jack for serial console connectivity, so you would need an adapter to use it. You'd be better off using something like this: https://www.amazon.com/Console-CableCreation-NETGEAR-TP-Link-Ubiquiti/dp/B0769J9QXP - however, if your Cisco switch has a DB-9 serial port, then this will work fine. **Q: Is the dcd pin on db-9 connected to the ftdi chip? with respect to usb port, what is the direction of this signal?** A: Hi, the 10ft USB serial adapter's DCD pin is connected to FTDI chip. About the signal direction, would you mind contact us directly via the order page's "contact seller" button, so we can send you a picture with more details. **Q: Which pins are rxd, txd, and gnd?** A: 3 for rxd, 2 for txd and 5 for gnd With this in mind, you may consider using a NULL adapter (male/female) to change rxd and txd pins, and/or Gender adapter (male/male). I keep both of these adapters at hand, in case of a signal mis-match. This is a very good product. I've used it with and without the adapters, very successfully. I especially like the quality and length of the cord,10ft, braided. ## Customer Reviews ### ⭐⭐⭐⭐⭐ This product is up to the mark! *by A***I on 18 May 2026* This product is up to the mark! ### ⭐⭐⭐⭐⭐ Great piece. *by A***R on 2 February 2026* works great! sadly our company still uses equipment that isn't network compatible. ### ⭐⭐⭐⭐⭐ Worked perfectly *by A***E on 20 December 2025* . ## Frequently Bought Together - DTech USB to Serial Adapter 10 ft USB to RS232 DB9 Female Cable COM Port with FTDI Chipset Supports Windows 11 10 8 7 Mac Linux - DB9 null modem male to female slimline data transfer serial port adapter 2 Pack - Gearmo USB to Serial RS-232 Adapter with LED Indicators, FTDI Chipset, Supports Windows 11/10/8.1/8/7/, Mac OS X 10.6 and Above --- ## 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.sk/products/259154220-dtech-10-ft-usb-to-rs232-db9-female-serial-port](https://www.desertcart.sk/products/259154220-dtech-10-ft-usb-to-rs232-db9-female-serial-port) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-08-08*
