USR-TCP232-302 Is a Low-Cost Serial Device Server,Whose Function Is To Realize Bidirectional Transparent Transmission Between RS232 And Ethernet. Features Of RS232 Ethernet Server Support DHCP, Automatically Obtain An IP Address And Query IP Address Through Serial Setting Protocol Support DNS Function Set Parameters Through Webpage Upgrade Firmware Via Network Auto-MDI/MDIX, RJ45 Port With 10/100Mbps Serial Port Baud Rate From 600 Bps To 230.4 Kbps, Check Bit Of None, Odd, Even, Mark And Space Work Mode: TCP Server, TCP Client, UDP Client, UDP Server, HTTPD Client Support Virtual Serial Port And Provide Corresponding Software USR-VCOM Heartbeat Package Mechanism To Ensure Connection Is Reliable, Put An End To Dead Link User-Defined Registration Package Mechanism, Check Connection Status And Use As Custom Packet Header Under TCP Server Mode, Client Number Ranges From 1 To 16; Default Number Is 4 The Global Unique MAC Address Bought From IEEE, User Can Define MAC Address Restore Factory Default Across The Gateway, Switches, Routers Can Work In LAN, Also Can Work In The Internet (External Network) Provide PC TCP/IP Socket Programming Example Such As VB,C++,Delphi,Android And IOS Support Customization Application Field Of RS232 Ethernet Server Industrial Data Transmission, Industrial Automation Security And Protection Monitoring, Public Security Smart Home, Power Control, Environmental Monitoring, Intelligent Agriculture Door Check On Work Attendance System,?POS System, Rice Selling System Building Automation System, Power Monitoring, Self-Service Banking System, Telecom Machine Room Monitoring Review: Simple to setup and use - I used this as a converter from an old piece of industrial equipment with a COM port to an application running on a virtual machine. All I can say is that it was simple to set up, and worked perfectly. I tried disconnecting and reconnecting the network connection, stopping and restarting the virtual machine and everything came back to life perfectly. Review: Hmmmmm. So-so. - Slow delivery, poor chinglish web user interface, no instructions whatsoever, security is lacking as it only allows a password 5 digits long, did not work in tcp server mode at least on the 3 systems i tried it on however udp server and client work just fine. Unit appears well built though and a nice neat form factor and it is very cheap compared to similar equivelants. ## Features - New model [USR-TCP232-302] RS232 to Ethernet converter is upgraded version of old one [USR-TCP232-200] - Serial RS232 To Ethernet Server, Used For Data Transparent Transmission. - USR-TCP232-302 Is Internally Integrated With TCP/IP Protocol.

All I can say is that it was simple to set up, and worked perfectly. I tried disconnecting and reconnecting the network connection, stopping and restarting the virtual machine and everything came back to life perfectly. ### ⭐⭐⭐ Hmmmmm. So-so. *by C***Y on 17 May 2017* Slow delivery, poor chinglish web user interface, no instructions whatsoever, security is lacking as it only allows a password 5 digits long, did not work in tcp server mode at least on the 3 systems i tried it on however udp server and client work just fine. Unit appears well built though and a nice neat form factor and it is very cheap compared to similar equivelants. ### ⭐ Poor support service *by S***. on 6 September 2021* Don’t buy this product - the setup software and user manuals have to be downloaded from a website that my Microsoft operating systems won’t access due to security concerns. When I was able to download them via my iPhone the pdf was unreadable. ## Frequently Bought Together - USR-TCP232-302 Tiny Size RS232 to TCP IP Converter Serial RS232 to Ethernet Server Module Ethernet Converter Support DHCP/DNS - 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)… - StarTech.com 3m Black Straight Through DB9 RS232 Serial Cable - DB9 RS232 Serial Extension Cable - Male to Female Cable (MXT1003MBK), 10 ft / 3m --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/48963711-usr-tcp232-302-tiny-size-serial-rs232-to-ethernet-tcp](https://www.desertcart.pl/products/48963711-usr-tcp232-302-tiny-size-serial-rs232-to-ethernet-tcp) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-26*
