DB9 RS232 to RJ9 RJ11 4P4C Equatorial Mount Control Cable 3M, Serial Upgrade Console Cable for iOptron Telescope IEQ30 Pro, IEQ45 Pro, ZEQ25 Astronomical Mount

This 3meter DB9 RS232 to RJ9 RJ11 4P4C serial control cable is specially engineered for iOptron astronomical equatorial mounts. It establishes RS232 serial communication between computer COM port and telescope mount console port, supporting PC remote mount control, handcontroller firmware flashing, parameter configuration and field debugging operations. Professionally matched pin assignment guarantees compatibility with IEQ30 Pro, IEQ45 Pro and ZEQ25 equatorial mounts. The DB9 female DSub connector comes with lockin screws to secure cable connection and avoid signal dropout during outdoor stargazing. The 4P4C modular plug clicks firmly into the mount RJ9/RJ11 communication jack. Durable flexible black PVC cable resists bending, abrasion and temperature fluctuation for outdoor astronomical field use. Please note: a USBtoRS232 adapter is required if your modern computer lacks native DB9 COM port. Ideal for astrophotography enthusiasts, firmware updates and computerdriven telescope goto operations. Verify your telescope mount model before ordering to confirm pinout compatibility.
