skyprodigy star sense firmware update, special cable needed?

[Eastridge]

Hi . we grabbed a skyprodigy 130 in a Amazon lightening deal. To have something small and quick when we don't want to go full on with the DOB.

All set up but handset is bringing back alignment errors and when 'manually' pointed using handset didn't seem to track.

So, we thought we would update software. Hubby is saying deletion website says it needs a special cable, but no such came with the scope nor can we see how to buy one.

Have we missed/ done something ? I have been following forum entries on skyprodigy since launch & have searched posts but can't find an answer and others seem to have updated firmware fine.

Thx for any advice.

Sharon.

This is the one you probably need http://www.firstlightoptics.com/astronomy-cables-leads-accessories/serial-cable-for-skywatcher-and-celestron-mounts.html

Thx guys. If it costs that much I'll send it back and see if replacement works out of the box.
