Rated 5 out of 5 by from The Only Cable That Would Work We tried several different cables from different vendors and for some reason this was the only cable that provided us continual connectivity to our radio modems and Computer Aided Dispatch software.

Rated 5 out of 5 by from A cable adapter I wouldn't be without This product was purchased to help my husband download his topographic maps onto his gps. With our desktop computer going down, all we had left was our laptop without a port to support his gps. When my son told me the type of adapter I needed, I was able to search the web and find this DB9 adapter. It was able to be purchased in 2 lengths but the shorter cable worked great with our laptop. My husband was able to once again downloaded his maps and the talk of buying a bigger and better gps was over, saving us hundred of dollars. The cable and adapter was just what was needed to help use his prior gadgets without having to buy new.

Rated 5 out of 5 by from old & new New PC's do not have serial ports. I had a legacy special device that needed serial on a new Windows 10 workstation. This was perfect solution.

Rated 4 out of 5 by from Excellent product I needed this adapter to connect a (home automation device) CM11A X10 serial interface to my Vista machine which had no serial ports. This works flawlessly and I felt was purcased for a fair price. The only negative comment I can make is that it did not come with software drivers. My Vista Home Premium machine was able to find the driver for me online as part of the "found new hardware process, however I feel that someone other than a "power user" may have not been successful at that point and would have needed support. All in all a great product however and I continue to be happy to do business with this company.

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.

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!

unfortunately we do not have a cable that will meet your criteria
