The ISS moves very quickly when it gets high in the sky. I observed this when I was tracking the ISS for an amateur radio school contact. I noticed that the antenna was moving very fast once the ISS was coming towards overhead and leaving from overhead. So it is possible that your mount cannot move fast enough to keep up and, hence, the message you are receiving.

Mount Discussions / Problem with "Start Tracking"
« Last post by Alain Líhostis on May 25, 2018, 03:51:44 PM »
Hi everybody
Just joined this forum and I want to present you my telescope.
This is a SW 254/1200 in a homemade observatory.
My mount is a EQ6 SW and I pilot this one by EQMOD and EQTOOTH.

So, I have also a problem with Satellite Tracker :
I use HWVSP and EQMODLX to connect my EQ6 with Satellite Tracker 2.4.9d and this one works very well.
I want to film the ISS when it cross around my observatory position.
But, when I run "Start Tracking", I have this message :
"Unable position telescope within time limits
May to increase maximum max slew rate"

Anyone have any ideas ?
Many thanks and excuse me if my english is bad.................I live in France...
ALAIN

Hi John,

Thanks for writing. I have tried to make Satellite Tracker work woth Allview mount but I accidentally fried the motherboard ( by simply plugging the cable coming from laptop to the wrong port on the mount head). So experiment was over there for me, not willing to experiment with something I have no clue about.

Of course I don't expect you to abandon you life because my demands :) Sorry to hear your constant agony with moving, hope things are going to improve to your situation. If you were replying to any of my previous emails by saying you don't have the time now, believe me I would understand it. But you didn't reply to me at all.

Anyway I don't want to any pressure on you and I really do appreciate your honesty!

Thanks and I hope Frank will and can do the heavylifting for you (reverse engeneering)!

I have not been doing anything as far as new development on the Satellite Tracker project as evidenced by the fact that no new versions have been released. My main goal in acquiring the Satellite Tracker project was to keep it alive and add some features to it. However, other things in my life have been taking up most of my time preventing me from paying attention to this project. Right now I am on the move again as my wife has been relocated 150 miles away to another job. So now I have to sell this house and move again. That seems all I do is moving from one house to another. I have about 15 requests ahead of you and you can look at my todo list on the forum. I actually was in the process of implementing ASCOM for Satellite Tracker and I have fully developed and tested it and it is ready to be folded into the software. That is as far as I got. So it is not that I am not interested in speaking to Mr. Liu at Skywatcher, it is just I do not have the time to do that right now.

I also pointed you in a direction where you could implement a strategy developed by other users that might allow you to operate the mount with Satellite Tracker. Please read reply #1 of this thread.

In reviewing the past messages in this thread I was being told that I would have to reverse engineer some code in order to extract the various message formats. That is something that I am not willing to do anyway. I gave you sample documents of what I am looking for and the Skywatcher people can see that and generate their version of the message formats according to the content of the sample documents. The document that you attached is not the appropriate document that I am looking for. I have sent an email to Mr. Liu today providing him the details of what I need and am looking for.

I received an email from the developer (Frank) at Skywatcher. He sent me the document below attached to this message.
I am really not sure if that's what you guys looking for and to be honest I care less and less.

I offered John to contact the developer directly, because you speak the common developer language. I am not a developer, I am a user of these equipment, my area is photography. Being a developer or at least understanding it's language is not something one can learn in a few weeks. But you choose not to have direct contact, instead I'm sending messages back and forth, which I wouldn't mind if there would be any development. But there isn't any to be honest. So I'm sort beginning to of acknowledge that tracking ISS with a lower end Skywatcher mounts simply won't happen anytime soon...

If you do locate the Allview message specification I would appreciate if you would post it as a reply to your question here for others to see and use. I hope this helps you get to use your mount with Satellite Tracker.

The message specification I am looking for should be similar to the message specification (CommandSet.pdf) that I have attached for the Meade LX-200 type mounts.

In addition, in order to make the connections you would need the wiring diagrams for your mount in a document similar to the wiring instructions I have included as an attachment called LX200AppendixF-G.pdf as well.

From these documents we can determine if the Allview mounts emulate the LX200 Command Set or one of the other command sets for the other mounts supported by Satellite Tracker.

Based on the email it seems like they are indicating that we can extract the command set from the code. While that may seem plausible this would take a great deal of time since it is a kind of reverse engineering of the code in order to obtain the Command Set document. One would think that the Command Set Document must exist in order to develop code. So let's see if we can locate the document of the Command Set that they used to develop the code.

Hi folks,

The good news is that Skywatcher offered their help to resolve the problem. An engineer - Frank Liu will help us, he offered his help, I have his email address so if anyone wants to get involved, let me know.
Here is the reply I recieved a few weeks ago:

"We ran your message by a Sky-Watcher engineer and got the following positive reply

The Engineer's name is Mr Frank Liu and is in CC to this email should you wish to make contact with him directly

Kind regards,
OVL

We are glad to help on this project.

Currently, we do not have a good document for the motor control's communication inferface, but we do have a sample code to demonstrate how to control the motor via the hand control port. Szabolcs can find the source code here. https://code.google.com/archive/p/skywatcher/

If Szabolcs has any question on the protocol, we are gald to provide direct support for him or the development team. You may forward my contact information to them to discuss technical issues directly.

We recommend to develop the application based on the AZGTi mount, because the motor controller provide better accuracy for middle to high speed slewing. We might upgrade the motor controller in the AllView to the one that is used in the AZGTi mount in the future.

The motor controller in the AZGTi mount supports both wired serial connection or Wi-Fi connection. And the SynScan Wi-Fi dongle has the potential to support Celestron's mount too. It might also work with Meade's mounts that use UART interface.
