THANK YOU SO MUCH for your brilliant product (US-101)!! ...
We tried [many other brands] and a few other USB to serial adapters. None of them worked!.. I’ve been buying and returning like crazy. ...
I finally called IBM/Lenovo out of desperation and somewhere in their internal knowledgebase was a mention of your product working. So I bought one from Buy.com as a test.. it arrived today. IT WORKS! =)
You are likely the only manufacturer on the planet that makes a working serial to USB adapter for IBM/Lenovo. I would sugges

I would like to thank you for sending out the windows 7 RS232 USB driver.ABM Electrical Contracting Ltd
I have had a lot of problems trying to get my EXFO fiber optic test equipment to communicate with my windows 7 laptop.
I loaded on your software for the driver and within 10 mins I could communicate with the EXFO.
Exfo's technical guys have struggled to find a soloution. Thanks to Brainbox the problem is solved
For some time I have been searching for a USB to Serial adaptor that works correctly with the Fanuc CNC controls fitted on the 600 UK products that I support.Les Robbins
I now use and recommend a USB to Serial adaptor supplied by Brainboxes Limited
They can look after all your RS232 hardware needs, be it getting your Netbook to talk to your CNC or your Desktop serving your CNC machines via RS232 multi port cards.
I find their products very reliable and their support team are very helpful.
After searching a lot on the internet for a good USB to Serial (RS232), I elected the Brainboxes US-101 for the following reasons:
- it really seemed to be a very good device and completely suited for my needs (size, features, technical data) - very good ratings all over the internet
- ready and tested for Windows 7 (64 bits)
- developed and made in Europe from an european company!
- lifetime guarantee
- lifetime support
- Brainboxes seems to be a company really [focused] on having good and reliable products and respect its customers
We have been massively impressed by the Brainboxes USB to RS232 converter. It is the best adapter we have found as it fully supports all 9 pins and has compatible drivers for windows 2000 through to Windows 7 64 bit meaning one solution can be used with all of our machines. We have been able to communicate with legacy PLCs such as the Honeywell IPC range through to modern PLCs such as the Allen Bradley Control Logix range. Unlike many other converters that can be hit-and-miss we are yet to find a device your converter will not work with. We have recommended your product to all of the automa

Well I must admit to being sceptical, as we only ever found 1 [other] device that worked [reliably] and I had to leave that on a project and have never found another since. It appears on first testing that your US-101s work very well…………..
needless to say I am very pleased as it is so hard to source a laptop with on-board RS232 nowadays. Very pleased indeed! Thank youPrinciple Communications
