Olympus MT20 not compatible with 2020 nightly build

[Bruno]

Dear all,

I have been using my scope succesfully with MM 1.4.23 20171026

However, I wanted to to update to the latest nightly build, but it seems
that as of that date (20171026) the MT20 from Olympus is not compatible
anymore: I get the error: "Incompatible device interface version:
(required=69; found=67)" . I attach the full error. Do you know how I could
get around this?

Thanks a lot,
Best
Bruno

This indicates that the device interface version of the Micro-Manager
Core differs from the version of the device adapter. That should never
happen with a freshly installed Micro-Manager version (these errors may
happen if you use a device adapter that you compiled yourself and then
inserted into an installation with a different device interface
version).  The MT20 adapter is still included in all nightly builds.

You could try installing Micro-Manager into a completely new directory
and run it from there to avoid strange things from happening.  You
should also look at the date of the mmgr_dal_ files and see if the MT20
has a different date from some strange reason.

Best,

Nico

Hi Nico,

thanks a lot for zour reply. The only reason why I need the MT20 is that I
change the filter cube position through it. In the MT20 adapter that comes
with the latest version of Micromanager I there is no FilterTurret control
to be added. I believe our adapter was written for us before my times in the
lab, and compiled with that interface version.

If I try to add the Filter Cube adapter that is under the Olympus folder, I
get the error: Error in device "Filter Cube": Invalid state (position)
requested (12). This is because the FilterTurret connector goes through the
MT20.

Is there a way to connect the Turret of Olympus IX81 microscopes directly,
without this routing via the MT20? This is a standard microscope body so I
guess there should be a solution.

Thanks a lot,
Bruno.

If you can locate that source code and email it to me, I can see if I
can add that to the official release.

I really hope that people will do that more often.  This is a nice
example of fixing this thing now, but not for others/future use.


Best,


Nico

Hi Nico,

I will do my best to track back the source code. Our group had in the past,
before my times, a suscription with Mark Tsuchida so probably is in that
direction.

Would it also be an option to decompile the the dll? Do you know how this
could be done? I tried with dotPeek by doesnt seem to support it. I attach
here the dll.

Thanks,
Bruno
