How long is the cable?** A: This one I have is approximately 1 metre in length. Also refer to my user review for another cable to extend the distance. **Q: Can anyone confirm that this really uses an ftdi chip inside and not one of those buggy prolific chips?** A: The simple answer is, yes this is a genuine FTDI chipset. You can always determine the chipset by using Device Manager in Windows, scrolling to the COM ports section, and then right-click on the COM port select Properties, and then select Driver and it will display the driver details which should show the manufacturer. However, I must take you to task regarding 'those buggy Prolific' chipsets. The genuine Prolific chipsets are highly reliable, and you can download from the Prolific website a chip verification tool that will positively identify the chipset. There are a number of cheap Chinese clones that appear to be Prolific, but which will fail this test and are not reliable. Hope this is of help. **Q: Hi. Would this work for a LG 47LD450 TV as it has RS-232C Connection at the back of TV for service and control purposes? thanks** A: Probably not .You need a standard RS 232 adapter not a null modem wired cable. **Q: Is this compatable for cutter plotters?** A: I can't get it to work if that's any help ## Customer Reviews ### ⭐⭐⭐⭐⭐ Startech 1.8 usb to serial review *by on Reviewed in the United Kingdom 11 July 2026* Ideal for the job ### ⭐⭐⭐⭐⭐ Works well to control RS232 devices *by on Reviewed in the United Kingdom 19 May 2026* Good product, had some doubts it would work first as I tried it before uploading the firmware, and it didn't work. But once the correct firmware was installed no issues worked like a dream. ### ⭐⭐⭐⭐⭐ Works Perfectly With A Flex Radio 6400M! *by on Reviewed in the United Kingdom 28 November 2018* I recently upgraded my amateur radio station to a Flexradio Flex-6400M software defined radio, and wished to be able to automatically tune my Ciro-Mazzoni 'Baby" magnetic loop antenna as I did with the previous transceiver. The 6400M is not provided with a serial port, but it does have a USB 'A' port. By using a USB to RS-232 adapter it seemed possible to control my antenna. Unfortunately the USB drivers built into the radio only recognise the FTDI chipset, so it is important to use an adapter so equipped. The StarTech adapter utilises this chipset, and, in addition has two LEDs to indicate activity on the transmit and receive data lines. The cable is sufficiently long that no extension is necessary, and the pin-outs are in the correct order so that a NUL modem cable is not required either. In my case, after setting the USB configuration in the radio, and setting the Ciro-Mazzoni RS-232 speed and protocol as required, it worked perfectly first time. If you are in a similar position and wish to control, for example, a Step-IR or its Italian equivalent the Ultra-Beam antenna, or otherwise require a serial interface to the radio, then I can thoroughly recommend this adapter as a trouble-free solution. ## Frequently Bought Together - StarTech.com 6ft (1.8m) 1-Port USB to Serial RS232 Adapter, FTDI DB9 Serial DCE Adapter Cable, Null Modem, USB 2.0 - TAA - DB9 null modem male to female slimline data transfer serial port adapter 2 Pack - StarTech.com 10' RS232 Serial Null Modem Cable - Null modem cable - DB-9 (F) to DB-9 (F) - 10 ft (SCNM9FF) --- ## 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.pt/products/48346688-startech-1-8m-1-port-usb-to-serial-rs232-adapter](https://www.desertcart.pt/products/48346688-startech-1-8m-1-port-usb-to-serial-rs232-adapter) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-08-23*
