This StarField Direct Interface Cable allows you to connect directly to an iOptron mount or iOptron hand controller with out the need for a USB to RS-232 converter cable.   Simply plug into your laptop ASCOM control or ASIAIR and connect to your mount easily.   

More information on the iOptron ASCOM control can be found in the iOptron ASCOM support page.  

• Finer control over your mount than a hand controller
• Consistent port numbering, regardless of the USB port used
• Replaces a damaged or lost hand contoller at a fraction of the cost.  (mount must have RS-232 port)
• Works with ASCOM compatible software, INDI, ASIAIR, Stellarmate, etc...
