Hi Knro,

lx200 if you this mean.
See Screenshot. It's the integrated driver.

I have a Skyview Pro with the an MCU Mod and had the same problem.
You can see my post here : indilib.org/forum/mounts/2148-rajiva-mcu-update.html

The best driver is the OnStep, but neither one works correctly. It should. But it does not.
In the meantime I am trying to make a custom driver to the MCU using the correct lx200 commands.
I had some progress but it's not ready yet and got stuck with some commands.
The MCU implementation supports a very small subset of the LX200 standard.
It's quite hard to make a driver for it.

Good Morning,

Please apologize if I can not always answer the same. I have family.

@KNRO
I have made 2 log files.
Indiserver -vv -l / home / thomas / indi_log indi_lx200basic
Indiserver -vvv -l / home / thomas / indi_log indi_lx200basic

"Sync" on Venus at "Slew" on Uranus. 2 times each.
I hope you can do something with it.
If you need other logs please tell it.

@NMAC
I have read your topic. I did not know you were still there. Is already a while ago
I would be glad if someone manages to get the thing to run.

I had already played with Kstars and Indi 15 years ago and it worked with this mount. Then there was a change in the libindi.
After that, nothing happened and I had to go to Skychart.

Somehow I had then Kontact to jasem and he has viewed with SSH the source from libindi. After that, it worked a while. At least until the first update but is certainly 6 years ago.

greeting
Thomas

Hi! Yes I am still trying :-D It's kind of a personal thing. If I can manage to do it, I will post it.

@Knro, I have the original author documentation (pdf) containing the command set but I don't know if I can publish because project had some conflicts and
was shutdown. I can send it to you if it helps.

Regards

Hello Thomas,
I have a HEQ5 that I modded with the Rajiva MCU Upgrade Kit also about 15 years ago :).
I was (and can use) the V4 Controller software to control my scope, but I want to use EQMOD with ASCOM. But I can not get it to connect to my HEQ5 mount.
Have you ever got your EQ6 mount to work with EQMOD and ASCOM?
I have tries LX200 Advanced Driver and LX200 Original Driver, do you think they should work?
Regards,
Markus

Hi NMAC (or anyone who has it),
Could you please send me the document containing the command set. I am also trying to get my MCU modded HEQ5 working with EQMOD?
Thank you,
Markus

Hi! I know I have it somewhere! It was very hard to find it at the time.
I will search for it. I remember it as a small subset of the LX200.

Found the page I used for a reference!
It's for a similar project but as you can see at the bottom of the page, the protocol is the same.

web.archive.org/web/20190308052918/http:...gbdt.com.au/eq6-old/

The original file is this one the the site if offline and there are no copies of it:

eq6.update.rajiva.de/eq6/data/mcu_doc.pdf

I will search for this file.

also see my original posting about this:

indilib.org/forum/mounts/2148-rajiva-mcu-update.html

and see the zip file attached, it may help too!

That's awesome NMAC, thanks for that.
I did some rs232 port sniffing and compared the values between using V4Control and ASCOM with the ASCOM LittleFoot Driver and I think I may have found an (hopefully the) issue.
As part of the ASCOM connection test, it passes a request to the mount for a few things, which are: #0:VX#, #:GR# and #:GD#. The mount replies to all of the requests, but it sends an extra character with the #:GD# which I believe kills the ability for ACSOM and EQMOD to correctly connect to the mount.
When the mount receives #:GD# it returns - "+00ß00".
It's very strange that the "ß" is in there, but V4Control still works fine with that, but ASCOM doesn't like it.
The Latitude and Longitude ASCOM shows after the connection (in Device Connection Tested) is 1612345:00:00.000 4898765:00:00.000, with the first numbers in each being clearly wrong.
When trying to connect in the LittleFootClassic Setup it errors saying 1612345 is out of range.

I am using MCU Firmware 4.17D and I did reflash my MCU Firmware to 4.10D, but is still had the same issue.

My next thought is to try and get the MCU firmware and modify it to remove the "ß", or try and get the ASCOM LittleFoot driver source code and modify it to correctly read values with "ß" in it.

Do you know if there is a later version firmware that 4.17D? I did see messages from Rajiva (from many years ago) talking of a version 6 Firmware, but can't find anything close and it seems there are no longer any traces of Rajiva on the Internet (maybe he was NEO :))?

Any thoughts on the "ß" in the value returned by the mount?

I remember having that char issue. That and another related to values precision. Tried to modify an old OnStep driver as it was the
most suited one. I had some things working, tried to debug ASCOM connection with CDC but eventually I gave up.

About the firmware that's the same as mine and it was the last one available at the time. There was another one, I think, but not compatible
the the MCU hardware. You would need to replace the MCU board for a new one.

Meanwhile I found the original file describing the protocol. It's attached. I hope you get it
working I would have to get mine too!

And now I found the most recent file for the LittleFoot Elegance.
Maybe this is the new one for the new firmware as it is v6.18.

I knew I should save this files :-D
