Sbig st4 manual

The cable is good and works with the SBIG guide camera. The camera is receiving the directional signals but its voltage drop is not enough to trigger our system. My guess is the camera ports are not functioning correctly. It is still under warranty. If the result is the same, your camera need to be sent back for repair.

But they did sell an adaptor to convert the signals to a RJ Jack.

That adaptor went like this What is the ST-4 Standard? The Dec commands are surrounded by the RA commands. If you start at the GND and move away from the unused connection the order is the same i. I would call this the ST-4 "standard"!! I have also built a breakout box for the autoguider cable and port. The box has 2 rj jack, as a passthrough, wired 1-to The box also contains 4 leds and 4 N.

Each led and push button is connected to a direction. Not only can I see which pin was shorted but I can use the puch buttons to short the directios as well. If I plug the box into my Scope this is the pinout of the Meade this is also what is listed as the pinout of the lx and lxGPS. There is no need to cross pairs of wires in the cable, we flip all or none of the wires! I would call this a ST-4 compatible plug!

Now this how it worked on my Meade. So this would mean a 1-to-1 cable would reverse all the directions and a flipped cable would not connect anything right at all!! The ground would not connect to ground!! But, these are not ST-4 Compatible. With this all out there I would love some feedback on this. What do you think Re: What is ST-4 Compatible? Post by dpanderson » Mon Jan 19, am Don, I certainly share your frustration with this situation. It would certainly make my life a lot easier if there was an actual standard for what a guide port should be, and if every manufacturer followed it imagine what it would be like if eyepiece barrel diameters did not come in just a few common agreed-upon sizes.

I have had to struggle with supporting as many configurations as I possibly can. Also, you have only touched upon the issue of mechanical compatibility, there is also the issue of electrical compatibility. I did a lot of reading on various fora, tried to look at as many manufacturers documents as I could access, etc. What seemed to be the most frequently occurring configuration for telescope mounts was what many referred to as the ST-4 "standard", which used the 6-pin RJ12 modular connector with a specific pinout.

You are correct that the ST-4 from SBIG does not have this connector style, but a large number of mounts are using this connector. Is there a way of reducing the blooming produced ie.

How to setup the guide chip I apologise for the lack of info just trying to see if anyone can help Regards jim. Jim Finis , Dec 15, Joined: Oct 27, Messages: 5, Location: Earth.

Hi Jim, Nice to hear an old piece of hardware is still being used. Teledyne e2v and Sony CCD sensors continue to be available into the future. The KAFE chip has no anti-blooming gates; the sensor is ideal for photometry because of this. Your option is to decrease the exposure time, telescope aperture, or to combine images shot at multiple exposure lengths.
