Only ZWO can post topic here
and we think USB2.0 is enough for guiding
I checked the wiring diagram and find that ZWO guiders, although claiming and illustrating a ST-4 pin out, use totally different pin out than ST-4 protocols on my SBIG guider ST-i.
Actually you are compatible with Orion or Vixen, not SBIG....
My mount is a Takahashi EM-400 with the new guider port and RD-12 communication cable.
SBIG pin 1 +RA
ZWO pin 1 N/C
SBIG pin 2 +DEC
ZWO pin 2 GND
And so on...
Looks like a full cable reversal 1 for 6, 2 for 5, 3 for 4, 4 for 3, 5 for 2 and 6 for 1.
I did not find a place to post this
Which one of us is correct?
Salt Pond Observatory
Blue Hill, Maine
just the line order of Takahashi is different from others
so you have to make a special cable
