Hi Everyone,
If anyone is having trouble finding a USB to Serial Adaptor that works with Windows 7 - 32 or 64 Bit versions - and all previous versions of Windows as well as Mac and Linux, you can get them through Harvey Norman, you may need to get the staff to order in Item IOH211 or order directly from the following companies.
Its is made be ATEN (
www.aten.com - as UC232A) but marketed/distributed by either IOGear - as GUC232A - or Conexus - as IOH211.
The Targus Brand adaptor - PA088 - doesn't (yet?) have drivers for Windows 7 but works ok with Windows XP (Tested) and Vista(Untested).
The Belkin Brand adaptors only currently work with Vista or earlier.
I have both the ATEN model for my Windows 7 Laptop and the Targus model for my Windows XP Laptop so can confirm that they do work.
I have used both with Stellarium to directly control my Skywatcher HEQ5Pro mount without the need for ASCOM drivers/software.
Hope this is helpful
Kind Regards,
Darren
