I decided to update my SynScan V firmware to the latest version using my old Windows 7 Lap top (about time SW introduced an Apple MacOS version!!!). Using a generic USB to serial cable was a disaster. I had difficulty getting the PC to recognise the handset but after some trickery got it to work and the PROM data was erased. However, horror of horrors the communication between PC and handset was then lost and left me with a non working handset with a blank screen.After researching on various forums I discovered that this was a not uncommon issue and that a chipped cable and socket was the answer. FLO was mentioned as a supplier of the genuine SW cable which I ordered and received by return (excellent service). Et voila - after installing the appropriate driver from the SW site I plugged in and the handset was recognised and the installation completed.The bottom line is that this is a must have cable and the service from FLO is 5*.However SW in their documentation only say to use “a” USB to serial connector and do not emphasise that a chipped version should be used and indeed that they supply a one. It is not even mentioned in the Optical Vision Catalogue although it is hidden away on their web site!
