Can any knowledgeable or successful user with this hardware arrangement kindly provide a purchase source link for the required serial interface cable between the LX200 AUX port and the ASIAIR Pro USB2 port.  (RJ type connector to USB2 type A connector)  The ASIAIR Pro only comes with half the cable...  and I've read of mixed success with different cables/sources.
  
Thank you for the forums ZW Obiwan!
