[sac-forum] Re: Help with Encoder

The face plate cover pops right off and then a retaining ring must be removed 
from the shaft. I'll bring it to the meeting. You may be able to save $50. You 
can test it, maybe it's started working again but I doubt it. If it is truly 
fried and the electronics are integral to the pins you may be SOL with this 
one. Either way, it's yours.

That's the unit, Jack.  What I need to try to do is take the 5-pin plug off the 
one you have an install it on the one I have.  Does anyone know how difficult 
that may be?  It looks like there is a face cover that snaps off (but if it is 
GLUED in place, the job could be a lot tougher).  Can you bring it to the 
meeting next Friday, Jack?

If it's an S2 4000 encoder type, I have a non-working one you can have to use 
for spare parts if you can do that. It's mechanically fine, just doesn't work, 
I think it got wet. Email me.

Tonight as I was setting up my C11, one of the pins on my RA encoder broke off. 
 I tried to solder it back on, but it was far too small for my tools to cleanly 
solder.  It is a 4000 tick optical encoder with a part number J2044 on the 
label.  

 

Is there a store in Phoenix that might stock this encoder?  If so, where would 
it be and would you have a phone number for it? 

 

I am also going to send an email to Starizona to see if they have the part in 
stock.  Last choice would be contacting Celestron, I suppose, although the DSCs 
are an after-market item and not Celestron's.
