Sky-Watcher SynScan USB Adapter Direct PC Control for Your SynScan Mount—Fast, Reliable, and Driver-Free The Sky-Watcher SynScan USB Adapter is the modern solution for astronomers who prefer the stability and speed of a hardwired PC connection. Designed to replace the traditional hand controller and older serial-to-USB solutions, this compact adapter offers a streamlined way to connect your Sky-Watcher mount directly to your computer using a standard USB Type-B cable. Whether you're running planetary imaging sessions, deep-sky astrophotography, or simply want a cleaner, faster interface between your mount and favorite planetarium software, the SynScan USB Adapter delivers with plug-and-play simplicity and robust performance. Compatible with EQ and AZ Mounts Using SynScan Protocol This adapter is compatible with most Sky-Watcher GoTo mounts that use the SynScan hand controller system. Supported models include the EQ6-R Pro, HEQ5, EQM-35 Pro, AZ-EQ5, AZ-EQ6, EQ8-Rh, and EQ8-R, as well as AZ-GTi and Star Adventurer GTi (when in SynScan mode). It connects directly to the hand controller port on your mount’s control panel—no handset required. True Plug-and-Play with Native Driver Support One of the biggest headaches in PC-to-mount communication has traditionally been dealing with finicky USB-to-serial drivers. The SynScan USB Adapter eliminates that problem entirely. It identifies natively as a standard USB HID (Human Interface Device), meaning no driver installation is needed on Windows, macOS, or Linux systems. Just plug it in, and you're ready to connect through Sky-Watcher’s SynScan Pro app, or third-party control software like EQMOD, NINA, or Stellarium. Improved Stability and Reduced Latency Compared to wireless control methods or older serial cables with adapters, the SynScan USB Adapter offers a more stable, lower-latency connection. This is especially important for long astrophotography sessions, where consistent communication between your PC and mount is vital for guiding accuracy and automated slewing. The direct USB connection ensures reliable command execution without the interference or dropped signals that can occur with Wi-Fi or Bluetooth modules. This is the preferred method for users running automated imaging sequences or observatory setups that demand uninterrupted data transfer. Compact, Durable, and Ready to Travel The adapter itself is small and lightweight, with a durable molded connector and flexible cabling that stands up to field use. Whether you're running a fixed observatory rig or packing light for a dark sky trip, this adapter fits easily into any accessory case. A standard USB Type-B port on the adapter accepts any common USB cable (not included), giving you flexibility in cable length and routing. Most users already have the appropriate USB printer-style cable on hand.
