I’m trying to connect the Plugable pl2303-db9 adapter to control a telescope (Synscan and EQ5 mount).
I’ve downloaded the latest drivers but cannot connect via Stellarium or Skychart. I’ve been through all their help files but nothing appears to recognise the cable.
Macbook pro (usb2)
RS232 cable supplied with Synscan controller
The drivers seem to be installed ok under USB.
I don’t understand the pinout diagrams and can’t find any more info, so I’m stuck! Any help, gratefully received! !](https://d2r1vs3d9006ap.cloudfront.net/s3_images/1114092/Stellarium_inline.jpg?1414597500)](https://d2r1vs3d9006ap.cloudfront.net/s3_images/1114092/Stellarium.jpg?1414597500)
