ZWO ASI 174 won't connect to PHD

[William Schubert]

PHD will not recognize my ZWO ASI174MM guide camera.  It will recognize my Imaging camera, the ASI 6200MM.  When I attach the 174 separately to my computer (MacBookPro), with the other camera disconnected, it always says "no camera found".  Different cables have the same result.  There are no additional drivers available to download from ZWO, since the Mac is native.  HOWEVER, if I connect the 174 to the 6200 via the 6200's built-in USB port, it DOES recognize the 174.  Then my problem becomes that I can't guide through PHD, because I am using a SB Paramount MX newer Series 6000 mount, which does NOT have the traditional serial port which I used with my older Series 5000 mount to make the traditional ST4 serial port connection between the 174 and the mount.  Ant ideas?  Thanks,

Bill

Are you using the ZWO native or ASCOM driver? If it is the ASCOM then use the little configuration button to make sure it is connecting to the 174.

I have one also and the interface is USB3 and not USB2 like from the ASI6200 back - check the port it is going into to make sure it is a 3. You may want to check the cable also as some are a little hit or miss.

Good luck,

Ken
