I think the best way to solve this problem is to:
1) Give up
2) "source" a RJ11 (4P4C) terminated curly wire...
3) replace the RJ12 (6P6C) plug on my pier with a RJ11 plug
4) Call it a day and be happy that it works.
I think I have uncovered a new way to have my cake and eat it too.
Since this is, at its core, all about remotely driving my CGEM mount from a dedicated imaging/observatory PC/Laptop from a warm "enclosed" position some 40' from the pier... While not having a rats nest of cables, controllers, dongles at the pier.
Lets consider this:
Step one: I take the HC, and put it away, safe in its foam lined box.
Step two: I run a 40' serial signal to the mount on the pier over a Cat6 cable and a homebrew Celestron PC Port Converter...
Step three: On the PC/Laptop I run my copy of NexRemote to drive the mount over the wire in step two... I will use NexRemote, to store alignments, park the mount, hibernate, etc.
Step four: On NexRemote I activate a virtual port and I use that to link to TheSky (since I really like that point and go interface)
So far that is pretty straight forward right?
Step five: So I'm thinking how to I align with a tethered PC running NexRemote that is about 40' from the eye piece... Wireless GamePad anyone? I'm sure one of the geeks at work is likely to have something that I can borrow and test.
So lets see:
Less cabling (at least at the pier)? Check
Less things to setup and take down at the pier? Check
Engineering Elegance? at the pier Check... at the PC? Not really
One less unsecured kinda expensive sensitive gizmo to be left outside? Check
Will it work? testing underway...
I wonder what the max range of a wireless gamepad is...
So close and yet so far away...
Been doing this for multiple years now.. I use a Logitech F710 wireless remote, nexremote with theskyx talking to the virtual port on nexremote.
You can even have nexremote connect to your favorite serial over wifi device, skysafari, skyq, bluetooth, etc.
