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.
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
