Thanks Paul for the schematic, it is very helpful, might be worth storing it in files along with the process for installing ASIair Pro
Just a small point, you're powering the mount from the ASIair?
Anyhows, just to let this small group know, received my new serial to USB cable WITH an FTDI chipset, followed the procedure and YES! it works.
Well I can move the mount, not tried anything else yet :)
Thanks to all for support and help
