I just wanted to thank you and the support and technical team at Brainboxes for sorting out my problem yesterday. I have been very impressed by your commitment to sort it out, and I appreciate the extra effort you put in checking the circuitry and biasing.

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.
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.

I changed to BrainBoxes serial ports on PCI cards (UC-235) ... and haven't had any problems since.
