This works even to the point of passing RS485 multidrop addresses. Since SysRq is just a key sequence represented by a binary sequence, as long as your source device doesn't intercept it, it will come out at the remote RS232 interface. **Q: Does this item come with an AC adaptor to provide the 5vdc?** A: yes **Q: I’d like to control a remote projector that only has an Rs232 port. Can each device be given a static ip?** A: Each device be given a static ip,but this product is a data transmission device. If you want to control a remote projector,we recommend the USR-IO424T-EWR. **Q: is the serial port modbus compatable?** A: it support transparent modbus data.do not support modbus RTU to modbus TCP. pls refer model USR-TCP232-410s which support modbus RTU to modbus TCP. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good *by D***N on 1 May 2024* Good product ## 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? - 🛒 **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.pl/products/364774502-usr-tcp232-302-tiny-size-rs232-to-tcp-ip-converter](https://www.desertcart.pl/products/364774502-usr-tcp232-302-tiny-size-rs232-to-tcp-ip-converter) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-24*
