Hi All,
Ive got a mount that uses the Losmandy dual axis control board. It has an autoguide port, I assume it is st-4 compatible. Ive also got an original Meade DSI ccd imager laying around. It looks to me like I could use PHD Guiding as the control software and hook-up to the autoguide port from my laptop via the Shoestring GPUSB adapter. Does this look right?

That's exactly what I use. Works very well.

Except the cable supplied with the DSI is not ST4 compatible.
I figured this out after a few days of head scratching. I bought some new RJ45 (IIRC) ends from Radioshack and reversed on of the ends. I think the MEade cable is straight through and ST4 is cross through. Or the opposite.

The DSI cable doesn't go into the ST-4 port though; it goes into the laptop so it shouldn't make a difference. The cable from the GPUSB goes into the ST-4 port so if you get the RJ45 cable from Shoestring you should have no issues.

Right, but the DSI cable doesn't work from the GPUSB to the ST4 connection. (at least mine had to be switched)

I seem to be missing something here. The DSI only comes with a usb cable that connects to your laptop so there would be no need to connect it to the GPUSB. And the GPUSB connects to both the laptop via usb and the mount via RJ45.
Do you mean your GPUSB cable had to be changed? Thanks.

My DSI's came with:
DSI Camera
AutoStar Suite Software
USB Cable
LX200 serial cable
DB-9 to RJ-11 Adapter
497 AutoStar Serial Cable

(had the #'s wrong, but the cable that came needed to have one end reversed. It works now. :)

Can anyone explain what the DB-9 to RJ-11 Adapter and cable are used for? I can't figure it out...

It's used to control a Meade telescope mount if desired (serial port autoguiding, planetarium software goto control, firmware updates) from a PC serial port.
