What documentation there is leaves out a lot of detail and it's very hard to follow. I'm still not sure if I can even configure this thing to accept connections over the wired Ethernet port. I did get it to work on WiFi. I made the mistake of plugging it in to a wired network too, though, which resulted in it unexpectedly working as a bridge so my laptop was getting DHCP from the wired network and couldn't talk to the serial device. I finally figured out what was going on and managed to set it up (only using DHCP - I can't figure out how to set a static IP address) and establish a connection to a Modbus RTU device via RS-485. From the fragmentary documentation it looks like this thing can do a lot, but it's hard to say exactly what or how to do it because it's so poorly written. The vendor so far hasn't responded to my request for help. --- ## 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.us/products/637643284-rs485-rs232-wifi-serial-server-converter-serial-to-wifi-wifi](https://www.desertcart.us/products/637643284-rs485-rs232-wifi-serial-server-converter-serial-to-wifi-wifi) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-11*
