Hi,

that's weird. It is probably a driver issue so please make sure that everything is installed perfectly.

Please follow this small guide too:

If you've managed to setup Antilatency in Windows, the trackers will appear among the tracking devices in Aximmetry without any further setup.

What you have to pay attention to:

- In AntilatencyService do not select any special Placement, choose "Identity".

- In AntilatencyService you can define Tags for the trackers. In this case, Aximmetry will display the trackers on these names instead of the serial numbers, which can make identification easier.

- Do not start Aximmetry while the AntilatencyService app is running, because the app locks access to the devices.

- This is the right base orientation (Y up) of the trackers (stick it on the camera approximately in this orientation to make the camera setup easier):

The further setting up of the system is identical to other tracking systems described in:

If we want to use ceiling markers - what the right orientation of tracker?

Thanks Ahmed,

Finally was a firmware problem in antilatency.... last firmware version 2.6.0 works fine!

Hi Alexander,

The tracker orientation should be the same.
The coordinate system itself is the one that should be setup correctly.

It is usually done by defining the correct environment preset in the Antilatency software.
I suggest contacting the Antilatency folks on this matter.

Does the Atilatency work with the Pro account? or Do we need Broadcast?

Yes it does work with pro or lower, as it is considered experimental right now.

Just to let you know. We oriented the tracker parallel to the floor and it worked fine. Just don't foget to check the Up rotated point.

What do you mean firmware problem? And what needs to be updated for it to work? I could not understand

Thank you so much for your response!
