Atik 314E and ST4 #41108
Hello,

I encountered an issue with ST4 port on my Atik 314E.
I finally measured directly ST4 output with a multimeter and an open cable the resistance between each 4 direction and ground according to the official manual.


I found that nothing happens. West, East, North, South resistance never reach the ground value no matter the time value set in indi module. Even worse,
the West pulse returns a red light.

I asked Atik to look into it.

Hello Sebastien,

Sorry to hear that you are having with your 314e. Have you tried this camera on a windows operating system to confirm that the guide port is switching OK? Have you used this connection in the past?

Best regards

Hello Vince,

I never used the st4 port with my 314e because I'm using it as a primary camera. Last week, I had problem with guiding and wanted to figure out if the problem was from the mount or the camera.
This is why I tried to investigate on this ST4 issue.
Long story short, my guide camera is using a non standard ST4 wiring with a mix between the 2 guide axis...
And for my ATIK camera, nothing happens on the hand controller of my mount or electrically with a multimeter.

You're right, maybe it's an hardware issue. I have a windows OS with Artemis software installed but the only way to activate ST4 port guide is on the field with a real guide star. Maybe you have a tip or a software tool to help on diagnostics ?

Happy to see Atik staff joining indi forum

Regards

Sébastien.

It might also be a ground issue in your setup. Check for possible currents between your power supplies. I had issues in my own setup embedding a 314e too, mostly coming from a crappy hashing power supply causing ripples on certain grounds but not all. In my case that was (probably) also causing strange noise in frames, but I was looking into infrequent resets in the mount and controller computer at that time. Things are better now though not satisfactory yet.

Hello Sébastien,

If you download our latest software, it includes a program called Dusk, under the guiding section there is the ability to pulse the ST4 port connections manually for longer than normal periods. This would give you the opportunity to either test with a multimeter or watch the motor drive on the mount. If there isn't any movement clean the contacts of the ST4 port using electrical cleaner as this is the most common cause of failure.

Best regards
Vince

Thank you for all of your suggestion.

I made a big step tonight with the program Dust which could send pulse via ST4 without the need of a guide star.
Conclusion, my hardware is working in all directions.
North pulse:DEC-
South pulse:DEC+
West pulse:RA-
East pulse:RA+



Back to Kstars/Ekos after updating, I played with the guide control and this is what I get on the RA/DEC display value on my hand controller :
North pulse : DEC +
South pulse : RA+
West pulse : no move, red warning in indi panel
East pulse : RA-
I don't understand why a couple of day ago, ST4 was not working in all direction....

In both case, I only plugged usb cable of my 314E from a Linux computer to a windows one.
I guess, I detect a software issue.

Eric, do you confirm with you're 314E the same issue ?

Sébastien.

Thanks for the feedback. I am using AtikGuideDirection enum:
typedef enum AtikGuideDirection
    {
        NORTH = 1,
        SOUTH,
        EAST,
        WEST
    } AtikGuideDirection;

and the guide calls are sent to this function: int ArtemisPulseGuide(ArtemisHandle hCam, int axis, int milli);

So I presume the int axis corresponds to the same numbers in the enum?

Hello Jasem,

Just wake up.
What if the AtikGuideDirection goes from 0 to 3 ?
West is faulty because outside the range with a value of 4. The others one acts shift.
North became South
South became East and so on...

I did the original ASCOM driver for the ATIK cameras and the axis values I used are in the range 0 to 3. This was used for several years and no one complained so I guess it was OK.

Looking at the documentation I've found places where the axis enum is from 1 to 4 and where it is 0 to 3.

Eurêka!! I changed the code to start enum at 0 and build an updated driver. It works!
Question is, what is the rule for Atik cameras? If this is specific to 314E, we have to specify this case in the code.

So it appears that maybe different cameras use different enums as Chris pointed out? We'll wait for ATIK to tell us which is which.
