On a side note. you can also build your own ST4 Guider board and then use that instead of the GPUSB : cost would be less than $10 for parts.

The FireFly MV and Chameleon has 4 GPIO pins via a BM07B-SRSS-TB connector, so you could connect the BM07B-SRSS-TB to the ST4.
Then you have one cable to the camera, and the camera connects to the ST 4 Port.
I use that all the time now. So I have one FW800 cable coming from my Mac , which is connected to the Grasshopper 2 (it has 2 FW 800 ports), and then I daisy chain a FW800 cable from the main imaging Grasshopper 2 to my guide camera (either a FW400 Flea or now my old Grasshopper 1 camera) and then the ST4 port is connected to the guide camera. So a single cable to 2 Cameras and the mount for imaging, guiding and mount control. For me, this is especially important during the winter to reduce the number of stiff cables I have to deal with (at -40°C all cables are basically plastic rods).
See page 109 and 110 of the Astro IIDC manual for more information on Hardware modifications.

You would connect the computer to the mount using a GPUSB from Shoestring Astronomy. They're reasonably priced, and you can get different cables for the various mounts that support ST-4 signals.

Wonderful!
I have a Mac and I'm trying the try version of Astro_IIDC before to buy it. When arrive the two FireFly I've purchase i'll try to use one of them for autoguiding my mount.
By the way, I should connect the camera to the computer and the computer to the mount, shouldn't I? There's not any direct way to connect the camera to te ST4 port, isn't it?

Hi, everybody!
I presume you don't use FlyCapture to manage this camera, but
Astro_IIDC.
Yes. FlyCapture does not run under OS X.
I ask: it works all right or you need some extra software?
Yes, their USB 2 camera support the IIDC protocol so they work fine -
all you need is a Astro IIDC on the Mac.
