Tera Grand - Premium USB 2.0 to RS232 Serial DB9 Adapter Cable 6 Feet - Supports Windows 11, 10, 8, 7, Vista, XP, 2000, 98, Linux and Mac - Built with FTDI Chipset and Thumbscrews

Bought a couple of these cables for my boss to use at work on his old Windows XP system.We use them to communicate with a few of our vinyl plotters (Gerber) and they work flawlessly.There was 1 small problem with the driver though, they require that you download it. However, the ones they have are not compatible with XP, so I had to find an older version of the driver. It did take a little bit of time to track one down.Drivers for Windows 7, 8,10 etc. are easily obtainable.These work as good as the cards you would need to buy for the newer systems, as they don't come with RS232 Serial Ports these days. so these cables are probably the better investment.Definitely less expensive.

Works well, arrived quickly

These are great. I use them to run my ham radio rigs via the PC. They handle the max baud rate of the radio rigs fine, work fine with Windows 11 and have a non-weird chip set - no driver worries! Dead simple to use - true plug and play. The only caveat is that all of my ham radio rigs all have male serial port plugs on them and this adapter has a male plug. This necessitates a straight through gender changer, so I keep some of those on hand, as I've never found these USB to Serial Port adapters with the female plug. Otherwise, these are perfect!!!

Good item

Works fine. However, finding the right driver was a bit of an adventure- there are many available. Some advice would be useful.

Worked well

Did not have instruction manual

Used the cable to connect an old external serial modem to my Windows 11 desktop USB port. It was instantly recognized by my computer and drivers were automatically downloaded from Windows Update. I did not need to use the enclosed driver disk. The modem is working well and I can now send out the occasional fax when I need to.

Received in time. Works perfectly. Thank you

Si te encuentras con el caso de que sea un puerto serie macho, tienes un problema. Añadirle uno no le costaria a la marca tan apenas nada, y evitaría disgustos, solo por eso no le doy las 5 estrellas, por lo demás, funciona como se espera.

Not functional. Loaded latest driver fron net. When connecting to laptop, pc responds that usb device malfunctioned. In uiversal serial bus controller under Device properties, it shows unknown device. Tried alloptions under document.Wanted to have stable usb to serial convertor against Cadyce Ca-US9 and i paid thrice the cost for this Tera Grand considering FTDI chipset is more stable than Prolific chipsetI am very much dissapointed with this product.I tried again and again three days and i tried other laptops also
