Flawless communication on line. No drops or garbage dump observed till 57.6kbps. ### ⭐⭐⭐⭐ Oaky products *by V***A on 6 March 2021* As per price very high price . ### ⭐ RS-485 interface is not as per standard spec and so does not work always! *by V***T on 4 June 2020* The EIA/TIA-485 standard says for representing the 'Space' ("0") state the differential voltage between D+(A) and D-(B) must be atleast -200mV. But an Oscilloscope connected to this converter RS-485 signal pins always shows around zero volts differential voltage for the 'Space' ("0") state. Tested with few commercial industrial equipment with RS-485/Modbus-RTU connectivity and majority of these industrial equipment fail to communicate with this converter. So basically useless! ## Frequently Bought Together - DTECH 1.5ft USB to RS422 RS485 Serial Port Converter Adapter Cable with FTDI Chip Supports Windows 10 8 7 XP Mac - Waveshare Industrial USB to RS485 Converter with Original FT232RL and SP485EEN Embedded Protection Circuits for Industrial Control Equipments and/or Applications with High Communication Requirement - Waveshare Industrial USB TO RS485 Bidirectional Converter Onboard Original CH343G Multi-Protection Circuits --- ## 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.it/products/540460932-dtech-usb-to-rs422-rs485-serial-port-converter-charging-adapter](https://www.desertcart.it/products/540460932-dtech-usb-to-rs422-rs485-serial-port-converter-charging-adapter) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-11*
