I could not find any way to connect SkySafari 6 Pro to Temma 2M mount via RS-232C cable that came with the mount. I acquired SkySafari 6 Pro through Apple Store a week ago and very new to the app. Do I need SkyWire any other way to communicate?

  Hi Simon, 

  You need our SkyFi 3:

  SkyWire is no longer available.

  Thanks!

  If you are using SkySafari 6 Pro on macOS you should be able to connect from your Mac to your Temma 2M via 

  1. USB-to-Serial cable
  2. RS232 cable

  Mac -> USB-to-Serial -> RS232 -> Temma 2M

  OR (definitely be able to connect from Mac via)

  1. SkyFi 3

  Mac -> SkyFi 3 -> RS232 -> Temma 2M

  If you are using SkySafari 6 Pro on iOS you must connect from your iPhone/iPad to your Temma 2M via 

  1. SkyFi 3

  iOS -> SkyFi 3 -> RS232 -> Temma 2M

  Hi Keiron,

  Many thanks for the reply. As per your 2nd reply, I run SkySafari 6 Pro on MacOS Mojave. I used RS-232 cable connection between my MacBook Pro and Takahashi EM-200 Temma 2M mount without SkyFi 3. But connection error popped up every time I tried to press connect button. I also do not know which connection option to choose in Communication setting. Please could you advise for setting up in SkySafari 6 Pro.

  Thank you in advance.

  If you are using a USB-to-Serial cable + RS232 then you need to have the specific MacOS Mojave USB-to-Serial driver installed.  If the correct driver is installed then under Connection Type you will see an option for "USBserial".

  If you do not see USBserial then you do not have the correct driver installed.

  Also, scope must be star-aligned BEFORE trying to connect with SkySafari.

  If further assistance is required please confirm the above and attach a screenshot of the error message.

  Thanks!

  Hi Keiron,

  Thank you so much for the advice. I will find and install the USBserial driver and test as per your advice. Then, I will update the outcome.

  Best regards,

  Hi Keiron,

  I finally got a USB to RS232 Connector that came with its own firmware yesterday. And, my MacBook Pro was finally able to communicate with Tak EM-200 Temma 2M mount. Please see the screenshots below. Before that I have tried a firmware/driver from internet without success.

  Thank you
