Hi,

Thanks. So an autoguider input on the mount is active low?

I'm looking to take autoguide signals from a guide camera's st4 port like the orion starshoot autoguider. of the 6 pins, are the 4 pins (ra,dec) held high till a correction is required, and then the respective pin pulsed low?
would you have pinouts of a guide camera?
how different is lx200 or the lx200 protocol or is it not related?
