Starsense compatibilty between mounts

[Luna-tic]

What are the differences between the Starsense for the AVX mount (or other Celestron mounts) and the Starsense sold for the Skywatcher Synscan mounts? For Synscan, it costs about $200USD more, and the ads show a 'junction block' that doesn't come with the one for Celestron mounts.

I have the Starsense for my AVX, and am considering adding a Skywatcher EQ6R. Is the software different between the two Starsense versions, or is one compatible with the other? Sure would like to be able to use the one I have with the Skywatcher mount if possible.

The junction box supplied with the Skywatcher version acts as an interface to translate the Nexstar handset commands to the Skywatcher protocols . Without it the Celestron Starsense and the Skywatcher Synscan mount would be incompatible.
