Have a look in the links section, electronics, Datasheet catalog I think it is. Hopefully you can find it there.

;D If you could see the things I have in my head, you would be laughing too. ;D

My guard dog is not what you need to worry about!

No luck.  I managed to stump google on this one.  Any other ideas?

Oh man, sorry.   :(  Have you tried contacting the manufacturer?

HAHAHAHA, that is who I bought them from.  He does not have the data sheet.

Maybe this can help! Try to contact the seller for more info.
Good luck, Lou

Doing some testing. This was originally posted by LAWAUTO. All is well, just testing somehting.

I know they are running 5V TTL compatible logic.  From there I should be able to reverse engineer the rest.  I bought one extra to blow up :-).  What does Mach require form an encoder?  Just a square wave?

yes just 5v square wave A and B channels.
What are you going to use the encoder for? if its your motors then it doesnt matter to Mach anyway as they go to your servo drives.

My cnc is stepper based, and home brew.  It likes to jam.  I am hoping if I add the encoders I can help solve that issue.
