With 600W surge protection and 15KV ESD safeguards, it ensures the safety of your devices. This compact hub supports up to three channels and features automatic baud rate detection, making it ideal for various automation applications. ## Description Asynchronous Half Duplex Communication This RS485 to RS232 converter allows to interface your devices using an RS232 communication link to an RS485 link and vice-versa. A built-in transient voltage suppressor (TVS) enables you to get double 600W lightning surge protection against the lightning strike over RS485 link, and 15KV static protection over RS232 link effectively protect your value devices against high voltage spikes. Simple Operation DCPC (Data Collision Protection Control) function can detect the incoming or outgoing data and automatically switch into the send or receive mode, then you don't have to worry about the data collision problems. It only requires three lines (RX, TX and GND) to get a RS232 to RS485 conversion, making it great for troubleshooting the serial system, fully plug and play.

They are RS-232 and the distance was too long.This worked well and was straight forward to set up. It is self powered though external power supplies, this way it can just pass data lines. You only need 3 conductors.It was convenient having screw terminals in addition to jacks to make hook up easier. ## Frequently Bought Together - DTECH Industrial Grade RS232 to RS485 Serial Converter 3 Channel RS-485 Expansion Hub with 600W Surge Protection TX RX LEDs Power Adapter Terminal Block - USB to RS485 Converter Industrial Adapter Original FT232RL and SP485EEN Fast Communication Embedded Protection Circuits Resettable Fuse ESD Protection - 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.vu/products/326658646-industrial-grade-rs232-to-rs485-serial-converter-3-channel-rs](https://www.desertcart.vu/products/326658646-industrial-grade-rs232-to-rs485-serial-converter-3-channel-rs) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-06*
