Four Port USB-to-Serial Converter

The individual port on/off switches are a lifesaver for debugging my telescope setup without unplugging cables. It recognized all four serial connections instantly on my laptop running Windows 11. No driver headaches at all.

Swapping between my mount, focuser, and filter wheel used to mean crawling behind the tripod with a different cable every time. Now all four stay plugged into one box, and being able to switch individual ports off in software is handy when a device locks up. Solid little hub.

Swapped out my old single-port adapter for this four-port box and it handles all my telescope mount, focuser, and camera without any conflicts. The individual power LEDs are handy for spotting which port is active at a glance.
