Did not come with cable. Driver folders is confusing, but XP32 did find something and installed. no manual. driver is the small kind.Update: Still no luck finding RJ-45 pinout. However it connected to Win 7 without a hitch (CD was not needed). RS-485 works great so far. --- ## 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/15073371-gearmo-ftdi-chip-usb-to-rs485-rs422-industrial-isolated-db](https://www.desertcart.co.za/products/15073371-gearmo-ftdi-chip-usb-to-rs485-rs422-industrial-isolated-db) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-03*
