Connecting Gemini one to laptop.


 

Hi
I am still having great difficulty in find a suitable working cable to attach my RS232 port to my USB laptop.?
I have bought several cables which don't appear to work. I think i have downloaded all the correct software from Ascom.
I would have thought you could by this as a dedicated Gemini part off the shelf.

Are there any special settings i have to program into the Gemini when i open it up on my laptop to to make a connection to my mount.
Would appreciate any help, getting frustrated!

Thank you
Regards
Ken??


 

Hi Ken,

First, you should see if you can find a serial COM port on your laptop after connecting the converter to it. It should show up under Control Panel->Device Manager, something like this (it might be a different COM port):

? ? ??

If you don't see a COM port, that means you don't have the right driver installed for your adapter or USB->Serial adapter?isn't working.

The serial cable pin-out for Gemini-1 is documented here:?



If you can't find a ready cable, you can always make one or ask someone with a bit of crimping/soldering skills to build one for you.

Regards,

  1. The RS-232 adapter should be full voltage range RS-232 not logic level which a lot of them are.
  2. How are you wiring the RJ22 4P4C plug?

A nasty thought occurs – did you buy this G-1 2nd hand?? If so do you know if the serial port actually works?

?

I can test and repair if necessary.

Hi David

Thank you for your reply.

I have had this set up from new, bought many years ago, but not used a great deal over the time. I have been using my Mead LX200 for many years for visual observing.

I now wish to go int atro photography were my EQ mout and refractor would be better for this job.

Thanks again for your help

It looks like my USB serial port ( COMS 3) is working it shows up as the window you have provided and i go on drives and they say they are up to date.?
The other end of the cable is the small phone jack, presume that's ok.?
Widow keeps opening saying not connecting to Gemini.
Thanks
Ken
