Previous Step

Required Hardware

  • SkyWatcher EQ6R-PRO models before 2019 with a SynScan hand controller with integrated RS232 interface and without integrated USB
  • ASIAIR Pro or Plus
  • a USB to RS232 converter cable
  • the original RS232 cable supplied with with your Skywatcher mount
  • a SynScan V4 hand controller, see the firmware requirements below 

Required SW and FW

  • a SynScan hand controller with the newest firmware release greater than V4.20SynScan 
    • SynScan V3: > Ver.03.38
    • SynScan V4/5: > Ver.04.38.06
