Re: Misconnected motor cables
Thanks! I see those connectors are under $5 each and available from Newark.com.?
Do you have a recommendation on the raw cabling to use?
I am an experienced cable/harness maker but that was many years ago!

Re: Misconnected motor cables

One of my bigger concerns is unplugging and connecting them every night of use causing excessive wear. i haven't run into that issue and i've been plugging/unplugging for maybe 8 years now. but you do have to go slow and be mindful
is there any way you can leave most of it connected and just move just the head?
The cables for my RA and Dec on my new GM811G would be terribly hard to plug in wrong.
They have a steel guide shroud, with a dimpled guide, and they are marked "Top" to help locate the correct orientation.

Re: Misconnected motor cables
Sonny, that dimple is not very stout and it will go in wrong. Michael is repairing one now, and
that's what happens to it. Others have done it to. Marking them is easy and cheap.

Subject: [Losmandy_users_io] Misconnected motor cables
As we all know its horribly easy to insert the standard Losmandy DIN motor
cables incorrectly which wreaks havoc with the motor encoders and decoder
ICs.
I did this myself while repairing a G-1 recently, and only just caught the
problem before I turned it on (which would have destroyed the new motor
encoder and decoder IC I had just fitted).
So I tried to insert *my own* motor cables incorrectly.? It was almost
impossible to do so because they're made up with good quality metal DIN
connectors rather than the cheap moulded ones with stamped metal outer
section used on the stock cables.
I recommend the Deltron 610-0600 (or similar) for use with the G-1 and early
(large) G-2.? I think (but am not sure) that the Gemini-2 Mini is fitted
with Lumberg KGV-60 or KGR-60 sockets (or similar threaded joint DIN), in
which case I'd recommend the Lumberg SV60 plug (or WSV60 for a right-angle
version) for the controller end of the cable and the Deltron for the other
end.
So I'd strongly advise everyone to make up their own cables (or get a friend
to do so) using good quality metal din connectors and twisted pair cables
(stranded Cat-6 would work well) wired as follows:
Wire pin 1 to pin 1, 2 to 2 ... 5 to 5.?? Use one pair for pins 1 and 5
(motor power cables), one pair for pins 2 and 3 (Encoder Channel A and
Encoder Ground), and one pair for pins 4 and 6 (Encoder Channel B and
Encoder +5V), and.
If you use screened cable connect the screen to the plug body.

Re: Port plugs to keep gemini (and other stuff) clean
That was such a great Idea Brian, I ordered three sets last night. It will help from putting cables in wrong along with Michael Herman' s recommendation to label your cables. I also put a spot of white paint on the key side of my RA and DEC plugs to keep
me from plugging them in wrong. " A cheap answer to prevent a expensive fix" HAPPY SKIES and good hunting.

but my environment isn't that dusty, it's more for doing whatever we can to maximize longevity.
We originally bought these for the computer ports, but I saw it worked on gemini too

Re: Port plugs to keep gemini (and other stuff) clean
I thought worm dust was called castings.
The worm equivalent to dog doo.
But this is a brave new world, with a great new star ship.
My worms, like my dog, sleep inside. ;^)

Yes, I always was using "on Camera".
I think I still am. But, me being me, if it works, I tend to forget the details until something buggers up. LOL!
I just hope I can share some ideas for folks to think about.

Well, that explains why whenever I did a Meridian flip, it was easiest to just close PHD2 and then restart it. Made it do a fresh guiding start post meridian.
yes
and not only that, you should recalibrate if you are imaging at significantly different declinations. PHD can automatically adjust the guiding rates if it knows the ha/dec (it knows this when you use ascom and pulse guiding), but otherwise you have to enter it in
i think you are probably using the "on camera" for your driver in PHD?

about the one I use. I must say, it has been a rock solid performer.
I'm mistaken, it's called an RJ-12 connector and of course the USB-B type cable. Sorry for any confusion.
When I mounted my USB powered hub on the telescope equipment, I bought to tidy up my camera wiring. (USB 2.0, my cameras are not USB 3.0 type. But I do use a a USB 3.0 powered hub and it is backward compatible with USB 1.0, 2.0, or 3.0)
I think tonight is going to be good for us weather wise.

And I've finalized my wiring so I'm confident it can work without any tangles.

when building my computer for remote observatory, I came across a pretty helpful accessory to help keep the gemini and my telescope-top computer insides clean.
these are port blockers (aka port plugs) that you buy and insert into unused plugs to keep dust and other stuff out of the insides of your computer
you can buy USB, ethernet (cat6), rj11, mic/headphone jacks, etc.
here's an example of plugging the extra gemini ports i'm not using:
you can find them on amazon and other places. usually it takes a few kits to get all the different ports for a computer, but here's one i used for the basics USB, video, and ethernet

Very nice... and clean.
Great photos of your organized gear, everyone!
Thanks for showing how nice it can be done.

Re: First Light, first night, Wow! GM811GHD under the stars.
Sonny I know I am better off LOL... without the AVX. It worked well when it worked. Good to introduce me to a GEM mount. It had two trips back to Celestron. The last time after three or four hours of nice usage it whent up in smoke. My guess
dew must have shorted out a motor or something, I dont know. That's when I knew I was done with Chinese mounts. Interesting note on the soft start motors. I will have remember that. Gemini 2 has worked well for me. It is not too difficult, I am finding new
stuff about it such as night mode ect...Their is alot going on inside of it, I dont think I will need all of it though. No need to be sorry on the YouTue chanel, I was actually Looking up videos on AWO Aiair Pro and Eagle 3 micro computers when I saw Sonny
Edmonds chanel , I knew it had to be your chanel. Thank you Sonny, HAPPY SKIES and good star hunting.?

Hi Deric,
I think you will be better off putting the AVX in the past. I know I am.
I don't damn the AVX, but I certainly damn the corporate philosophy.
My AVX was a hard teacher. But I did make it work.
And now, I'm loving my new Losmandy mount! I can truly appreciate how good it is!
One of the nuances I've noticed is the motors are what we call "Soft Start". the drivers ramp up the current so they gently start the load moving.
Many might not know about that, but I do from my Electrical background.
I think the learning curve is going to be much easier, and much better than the old AVX. My learning curve with the AVX had a lot of boulders rolling down on me. LOL!
The Gemini 2 seems to perform amazingly better. Just watching it in Stellarium is totally different in a very good way.
Sorry you had to find my Youtube channel. I will amend my signature to make it easier.
I hope you enjoyed some of it.
