Rated 5 out of 5 by from I would buy this again. I needed a serial adapter and this worked great.

Rated 2 out of 5 by from Hardware Good - Software Bad I use this product several times a week in my job, and so do some of my coworkers. The product is nice for us because our laptops do not have Serial ports, so we use this product to console into networking equipment. The biggest issue I have with this product is the drivers for it. I use Windows 7 64-bit and so do my coworkers. This device will almost always (4 out of 5 times) bluescreen my laptop, especially when I'm in debug mode or if I'm receiving a lot of info from the console. I have tried the last three versions of the drivers and none of them have helped the bluescreen issues. CablesToGo: Please, PLEASE fix the issues this device has with Windows 7 64-bit. If a new driver is not released soon, my coworkers and I will have to find a more compatible product.

Rated 4 out of 5 by from works like a dream Used to convert roller mouse from old computer to new laptop. Worked just as avertized. All i had to do was plugin and let computer find drivers, was working within 3 minutes. Much more enjoyable than finger pad that came with new computer. Very happy with this buy.

Rated 2 out of 5 by from 64 bit drivers don't work This works great as long as you are on XP 32-bit. If you are on a 64-bit machine it will BSOD your box when you run at a speed of 19200. No matter what I plug it into, speed 19200 works for about 1 min then I get a BSOD with Multiple_IRP_Request errors.

Rated 1 out of 5 by from Does not work with 64-bit Windows 7 This cable/driver installs properly but my 64-bit system cannot connect to any devices through it. Apparently this is a problem with cables from other mfg.s as well.

Rated 2 out of 5 by from Doesn't support higher voltage RS232 product fails to communicate with older devices that have higher RS232 signal levels. This device has a TX signal level of about -6.4 volts. Older devices range from -10 to -12 volts. The signal level in the older devices appears to hang the hardware and then the Windows Device driver as well. Works well with newer device that have compatible signal voltage levels.

Rated 3 out of 5 by from Did Not Work I purchased this UART converter cable to connect to two new HP 1950 12XGT switches via their console ports. It will not connect from my laptop to either of them, connecting this adapter cable to the serial to RJ45 console cable that came with the devices. I cannot say that the adapter cable is bad, because it might just be an HP serial cable pinning issue, so I will not return it. Hopefully that is the case, because if I knew the cable was bad for sure, I would return it. Since serial connections are SO obsolete, I have nothing to test this cable with, so I am stuck I guess.

Rated 2 out of 5 by from Only worked part of the time for me This cable worked but then the device I was using it with hung. An alternative cable worked 100% of the time. The device was a serial scale. Further this cable has no ability to screw into mounted posts. The screws are embedded in the molded plastic which was a problem for me. I had to take out the posts on the connecting device.

Rated 5 out of 5 by from Worked perfectly with Win7 I was able to interface a UltraSmart Glucometer which had a DB9 interface to my new Win7 laptop's USB port. The vendor of the UltraSmart did not recommend using Win7, yet the UltraSmart worked with Win7 using this interface cable. Software driver installed on Win7 without any problems.

Rated 5 out of 5 by from Works great on a MacBook Pro I use the USB Serial DB9 Adapter Cable on a MacBook Pro to connect to Cisco hardware and a few HP MSAs. Works great and is VERY reliable. Cables To Go support via chat provided me a link to the driver. The driver had an install program. Highly recommended USB Serial DB9 Adapter.

Rated 5 out of 5 by from Works great with sewing S/W and Bernina This adapter works well with Explorations embroidery s/w and my Bernina sewing machine. The product label does not indicate that software is included in the package. I discovered the CD after downloading the driver from the internet.

Rated 5 out of 5 by from Good security product This product was recommended to me by Schlage security systems to convert their serial cable to our USB computer port. Not any cable would work. I found that this cable worked after buying others. If you need commercial quality like we do for our security system, this adapter is great. You can't have one problem when dealing with security, and this cable absolutely works. Also, great technical support if you have compatibity problems. My software had a wrong setting which they and Schlage helped me figure out the problem. Great cable !!!!!!!!!!

Rated 2 out of 5 by from no drivers To use it I had to search the internet for drivers. Still questionable each time I use it. A competitors works better and included the correct driver.

Rated 2 out of 5 by from Unreliable with Win764 Does not work reliably with Win7-64bit on laptop but seems to work ok on our Win7-64 bit desktop. Don't know what the difference could possily be. Runs about a minute and then gets hung up. Cables TO GO has indicated several times they;re trying to get this fixed. Running 2400/8/1/N so not pushing the speed barrier at all! Driver on CD is late 2010 and not up to date. Use the driver on the website. We've been trying for months to get something that will work reliably on WIN764.

Rated 5 out of 5 by from USB to Serial Adaptor I'm an electronics system technician and I use this adpator to service more than 350 pieces of equipment. I use this adpater with Vista Business edition and a 3.0 USB port. It works great. I also like the that the length of the cable is longer than my old 2.0 adapter. No cons.

Rated 5 out of 5 by from Cd driver is included with package. After tossing the package in the trash, i read a review from a customer who stated that the cddriver (although not stated on the package) comes with the adpter. Needless to say i had to go fetch it out. But the adapter works well with my stentura stenograph machine

Rated 5 out of 5 by from It worked great This adapter was used to connect an old court reporter's steno machine to a modern laptop. I had to get from the db9 connector on the steno machine to the laptop and the only port available was a USB port. This did the trick and worked fine.

Rated 5 out of 5 by from Great product. I transfer data from 9 pin devices to computer. Cable works with Windows 7 Pro 64 bit as advertised. Set up was easy. I plugged it in. Device was recognized by computer and was ready to go. This cable does what I expected.

Rated 4 out of 5 by from Works like a charm Great for connecting to legacy devices such as old phone systems, fire alarm panels, security systems, etc. Since new computers no longer have Serial Ports, this is the best way to go by far.

Rated 5 out of 5 by from A real money saver I collect DVD's and use a laser scanner in conjunction with a program to keep track of my collection. I recently bought a new computer and found it had no serial port. I needed to connect my laser scanner so I purchased this adapter cable to make my serial port scanner work as a USB unit. It saved me having to buy a $99.00 new scanner. It works great and I'm back to filing my DVD's.

DO I NEED SOFTWARE FOR THE DB-9 TO USB ADAPTER TO WORK

Asked by: BILLYBOB
Using this on both Windows 7 and 10, I needed to load a driver to get this to work. Once loaded it works with various software the needs access to a Serial Comm Port. You will want to verify the Serial Comm port number within Windows Device Manager

I measured this cable generating signal levels at -7V and +7V. Although the RS232 standard specifies signal levels can be as low as -3V and +3V, the levels generated by this adapter may not work in all applications (e.g. industrial). My PC generates signals at -11V and +11V. Do you offer a USB to DB9 serial adapter that generates signals closer to -15V and +15V than -7V and +7V? Thanks!
