This device simple converts RS-232 to RS-485. Any RS-485 devices hanging on the other end have to have their own addressing scheme via the protocol you're using. **Q: Does it work with modbus ascii rs485 devices?** A: Yes, this RS-232 to RS-485 adapter works for modbus ascii rs485 devices. If there is any usage issue, please feel free to contact us via the order anytime. **Q: Does the baud rate auto-detect work if the RS232 side listens only (no transmission)?** A: Only there is signal transmission between RS232 and RS485, the baud rate will be auto detected. **Q: Does this do 485 to 232?** A: Yes, I used this converter for Modbus communication from rs-485 to rs-232. ## Customer Reviews ### ⭐⭐⭐ good *by K***R on 1 February 2024* good ### ⭐⭐⭐⭐⭐ Good *by E***N on 20 December 2023* Ok very nice... ### ⭐⭐⭐⭐⭐ Works PERFECTLY, bus powered, Automatic RS-485 Transmit enable, low latency *by T***E on 6 December 2019* I couldn't ask for more, this thing works great! I needed to send some commands to an RS-485 peripheral to provision it, and it worked perfectly. Its totally bus powered (but provides option for external 7-9vdc power on the RS-485 side). The most important thing when using RS-485 half duplex is fast control of the DE (driver enable) line. This thing handles it automatically and perfectly. Able to send RS-485 commands via terminal and when not sending it releases the transmit line quickly to switch back to receive (<1ms). I was originally contemplating putting one of these together out of a RS-485 transceiver IC, and piddling some TTL stuff together to handle the DE line switching, but for this price, I couldn't justify spending the time building it even if the components were free and sitting on the shelf. A good RS232-485 converter is a handy thing to have in your toolbox for debugging if you work with any RS-485 devices, and this one is well built and super easy to use (it even came with a phoenix style screw terminal block, lol) ## Frequently Bought Together - DTECH RS232 to RS485 Serial Converter Adapter with 4 Position Terminal Block for Industrial Long Haul Communication Data Supports 600W Anti-Surge - OIKWAN USB to RS232, USB Serial Adapter with FTDI Chipset,USB 2.0 to Male DB9 Serial Cable for Windows 11,10, 8, 7, Vista, XP, 2000, Linux and Mac OS(6ft)… - DTECH RS232 to RS485 Converter Serial Adapter with 4 Position Terminal Block for Long Haul Data Communication Supports 600W Anti-Surge --- ## 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/261153127-dtech-port-powered-rs232-to-rs485-converter-adapter-for-industrial](https://www.desertcart.tn/products/261153127-dtech-port-powered-rs232-to-rs485-converter-adapter-for-industrial) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-29*
