Essentially my USB to serial converter is built into the cable and look like a regular USB cable and it solders into the EK box. I found it a bit restrictive which is why I want to get the Bluetooth version working as quick as possible. I would suggest at this stage to just consider USB to serial adapator.
With that I am redesigning the board to accomodate the Bluetooth module and using modules for all parts to allow for easy upgrade without junking the whole unit and starting again.
As far as drivers I believe VISTA and Windows 7 will have inbuilt generic driver. I have not tested it on XP ATM. I expect the drivers are for earlier versions of Windows but unsure of Jaycars converter (ask Mr B). The USB to Serial convertor I originally tested was annoying and has a bright blue external high intensity flashing LED's
that show communications. Light up the whole dark sky area.
On another point I found the optical encoders draw hefty current. I hope to have some good news on some encoders that I got for trial. So far I have been a bit disappointed with them but I have an idea. If it is successful then it may allow the whole EK box to run on USB power instead of a power pack or batteries. Most optical encoders are not very efficient.
But if I go to Bluetooth I will have to go back to external power again.
