Finally got this to work with my telescope's guide camera setup after fiddling with the pinout. The compact size is great for keeping the cable clutter down at the mount.

This little adapter let me ditch my messy cable nest when hooking up my mount to the laptop. The RJ12 connection clicks in firmly, which is a relief after dealing with loose serial plugs before.

Finally found a clean way to connect my mount's RJ12 hand controller to my laptop's DB-9 port without cobbling together random adapters; the modular design made swapping cables effortless. It clicks in securely and solved all my connectivity issues during the last imaging session.
