Does this adapter incorporate that 120 ohms internally or do I still need the resistor?** A: Termination is only required when both length of line and baud rate affect propagation delay. I've used this adapter without a problem with a few different components with lengths way under 1000ft and never needed a termination resistor. You may have to double check line length and baud rate to verify propagation delay in nanosec to confirm whether you'll need a terminator. I hope this helps. **Q: is that really a Mini USB? it looks like a Male B USB connector.** A: It is a Full Size Male USB Connector, not Mini USB. It works really good... and I find it surprising it says Mini; I don't remember it saying that back when I bought it. I hope this helps. **Q: Is there any visual indicators that it is "working"? i.e. transmit, receive, power, etc. LEDs?** A: In the instruction sheet that is shown it says:"Power indicator light and data traffic indicator light are also available with the converter for malfunction indication"There are PWR, RXD and TXD labeled LEDs on the module just above the terminal block. **Q: Is this unit plug and play with Windows 10?** A: Yes, it fully supports Windows 10. ## Frequently Bought Together - Gearmo USB to RS-422/485 Converter FTDI CHIP w/Terminals - 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 - 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.co.za/products/3981160-mini-usb-to-rs485-rs422-converter-ftdi-chip-with-screw](https://www.desertcart.co.za/products/3981160-mini-usb-to-rs485-rs422-converter-ftdi-chip-with-screw) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-29*
