RS-232 only. Great product if you want four RS-232 ports on your computer, but won’t help you with handling RS-422. **Q: Is there any update about Windows 10 compatibility?** A: Works just fine on Windows 10. If your computer has internet access, just plug it in, the latest drivers are available from Windows Update and Windows 10 will find them on its own (with internet access). Otherwise, check the manufacture's site, there is an .exe installer there. **Q: For use connecting to console ports on computers or switches or such, are gender-bending and/or null modem adapters required?** A: The way this USB to RS232 serial adapter is being used by me is to connect it to a computer that has only USB ports and no RS232 serial ports. The four DB9 (male) connectors of the adapter are then connected to serial devices, either directly or with a RS232 serial cable (not a crossover/null modem cable) to my devices that require a RS232 serial connection to my computer. In general, if the device to which this adapter is being connected requires a female DB9 connector on the attaching cable, then a gender changer would be required. If the serial device to which the adapter is going to be connected requires a crossover/null modem serial connection, then a crossover cable/null modem adapter would be required. The answer to this question will depend on what is required by the device to which this adapter will be connected assuming the connection to a computer USB port and adapter drivers are installed correctly. **Q: What is the voltage on the Tx pin (pin 3)?** A: -5.7V for logic high, +4.2V for logic low, measuring from pin 3 to pin 5. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Five Stars *by A***R on 23 March 2017* Great ### ⭐⭐⭐⭐⭐ Reliable Connection for Legacy Devices *by S***E on 27 August 2025* I needed to connect multiple RS232 devices to my laptop, and this adapter works well. The drivers installed quickly, and data transfer is stable. It does get a bit warm after long sessions, but overall, it’s a solid and dependable solution for older equipment. Very good value for the money, very stable conenction, windows preserves COM port numbers when you change the USB port (Persistent COM ports), the cable lenght is short but you can use an extension. Very easy to use. ### ⭐⭐⭐⭐⭐ Works as designed on Windows 7 *by H***Y on 7 August 2012* This USB to serial port adapter has 4 separate serial cables that connect to a single USB 2.0 plug. Each of the 4 serial cable ends is slightly more than 3 feet long. The USB cable end is one foot long. Total end-to-end length is a little bit more than 4 feet long. Each serial cable is labeled "1", "2", "3", or "4" which makes it easy to track your connections. The connections always retain the same com port, so you won't need to reconfigure you software after restarting you computer. The adapter has 3 separate LEDs: red = power, green = TX, yellow = RX. The adapter comes with a CD-ROM that contains USB 1.1 and USB 2.0 drivers for many operating systems including Linux, Mac, Windows, and more. The release notes on the CD-ROM mention that newer drivers can be found at [...] No paper instruction manual is included which might cause inexperienced computer users to have moderate difficulty with the setup. Experienced users will find the setup straight forward and simple. Installation on Windows 7 was easy for me. I found the appropriate installer on the CD-ROM. I had to right-click the installer and select run-as-administrator. The first time I plugged the adapter in it took several minutes for the device to be detected, so be patient. Subsequent detections are fast. All 4 serial adapters can be used simultaneously. Overall I am satisfied with the quality of this device. ## Frequently Bought Together - Gearmo 4 Port USB to Serial RS232 Adapter FTDI Chipset, Supports Win 11, 10, 8, 7, Linux, Mac w/ESD and Surge Protection - StarTech.com 10' RS232 Serial Null Modem Cable - Null modem cable - DB-9 (F) to DB-9 (F) - 10 ft (SCNM9FF) - Gearmo USB to Serial RS-232 Adapter with LED Indicators, FTDI Chipset, Supports Windows 11/10/8.1/8/7/, Mac OS X 10.6 and Above --- ## 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.tn/products/348327874-4-port-rs232-ft4232hl-professional-usb-to-serial-adapter-tx](https://www.desertcart.tn/products/348327874-4-port-rs232-ft4232hl-professional-usb-to-serial-adapter-tx) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-26*
