How to connect CN16 GPS module to C8-SGT?

Hi all!

I'm having a problem with my recently bought Celestron C8-SGT and the
optional CN16 GPS Module..

The manual says "attach the GPS Module" to the Base Drive Port of your
Motor
Drive Panel... ok, fine.. but there is NO Base Drive Port. (The Box by the
way speaks of the "Auxiliary Port")... but my Celestron C8-SGT (Advanced
Series) just has a Port for "Handcontroller", "DEC" and "Autoguider" ....
no
Port marked as AUX or Base Drive ....

So how can I connect that GPS Module to the Scope?

I re-read the Manual again and again. It always says my telescope is
compatible with that GPS Module..

I mean... am I stupid or where is the problem here?!?

please help me out...

thanx in advance..

I think you need to talk to Celestron. The manual is referring to the layout
on the CGE series scopes, that do have 'AUX' ports. However the signalling
used on these, is the same 'data', as is fed to the servo motors on your
scope. My 'guess', is that there is an optional adapter cable, which plugs
in to perhaps the 'Dec' motor port, and then offers the extra socket. Your
scope is meant to be able to drive the GPS module, and an email to Celestron
after the weekend, should find how this is meant to be done.

Hi Roger,

thanx for that.

Yes, i was irritated, since the CN16 GPS Manual just talks about the
NexStar
5i, 8i and CGE Model, but my manual and the celestron product desciption
for
my telescope also talks about that GPS Module:

quote:
"The Advanced GT Series telescopes include these high performance
features:
GPS-compatible with optional CN16 GPS Accessory (#93963) "


anyhow, I wrote celestron an email now. Lets see what they mean....

cheers

It is a definate case of the problem of producing new models, and then not
looking at the 'interactions' here, or keeping their nomenclature the
same.... :-)
They list an adapter for increasing the number of 'aux' ports available, and
the more I think about the signalling (the aux ports, use exactly the same
signal connections as the handcontroller port - you can actually plug the
handcontroller into the 'aux' port if required), so my suspicion now is that
this adapter is effectively a 'Y' connector, and on your scope will be used
into the handcontroller port. The motor port, though it has the right serial
data, has 12v, rather than 5v power.
On a scale of 0-10, the documentation on this rates a sub zero score!...
