PSN communication question!

jack

Hi, I have a PSN communication problem.
The PsnTracker packet is sent locally to the device via PSNServer, the data includes position, speed, orientation, acceleration, targetPosition, timestamp information, and all data are not empty. When I look at the device, I can receive the source link and it is shown in green; when I open the device View Tracker interface, I can see that Tracker information has been received and the Name column is shown correctly, but Posx, Poxy, Poxz, Rotx, Roty, Rotz, etc. show zero values, so I am not sure what the problem is.
The test program uses the “posistagedotnet” project.
Thank you very much for your help!

Hi jack. From the top of my head, I’d say that if you are receiving tracker information then, the problem is likely not the network. However, you can examine PSN traffic on your network using Wireshark and the PSN dissector available at https://github.com/vyv/psn-dissector This should help you diagnose network issues and more importantly whether the data you are sending is good. Second, there are sometimes device specific settings or special configuration required on the device (receiving end) in order to properly use PSN data. You might find information in your device manufacturer’s documentation. Lastly please note that VYV maintains and supports the C++ implementation. For questions and issues with the .NET implementation by David Butler, you should get in touch with the author.

Hi strinh, thanks for the suggestion. I used Wireshark to capture the C++ implementation (https://github.com/VYV/PSN-CPP) and the .Net implementation (https://github.com/pixsper/posistagedotnet) separately and found some differences in the packages, without analyzing the specific differences for now; running C++ implementation examples/vs2015/psn_server project to communicate with the device, the device network shows red, enter the View Tracker interface Name column data is correct, other columns are still 0; I think the PSN_INFO_PACKET package is delivered normally, PSN_DATA_PACKET package is not delivered normally. What is the next step to troubleshoot this error, is it because of my device problem or is there a bug in the code in the C++ implementation?
The C++ Implementation upgrades the Windows SDK to 10.0 at compile time, which should have nothing to do with this exception.

Hi jack.
Although one can never rule out bugs, this version of the C++ PSN library has been in use for several years on dozens of projects so I would rate that possibility as ‘unlikely’

So to trouble shoot further
First make sure you can see the values for the trackers in the Wireshark capture. Use the PSN dissector to inspect the network trafic. If the values coming out of your server are good. Since you are using the example code, I expect this will be the case.
Second you appear to be using a MA lighting console. One of my colleagues with production experience with PSN and Lighting console, was kind enough to produce this guide to setup PSN

<Begin Help with MA>
PSN configuration MA / Photon

In order to make PSN ID values display in MA, you will have to patch at least one Stage Marker fixture in your project.
MA uses Stage Marker to link PSN ID data to the MA 3D world position. Once achieved, the user can use a lighting fixture to point at the Stage marker and enable tracking capability.

Here is how to patch a stage marker and make PSN data available on the MA system.

Go to “Patch and Fixture Control” under the “Setup” menu of MA and create a new fixture layer

On the “Add Fixture” menu select “From Library”

Type "Stage marker’ in the “Fixture” search text bar and select “Stage Marker II”

Add as many Stage Marker you need for tracking. Adding one single Stage Marker fixture is sufficient to enable values display of all PSN IDs:

Close and save your patch before going to the PSN configuration menu:

In the “PSN Network Configuration” menu, make sure Multicast address and Port corresponds to the external PSN server settings and that your client is enabled. Click on “View tracker”
(Note if you are using the default values, the multicast address is 236.10.10.10)

You should see a list of all available trackers. In green is the active ones and in black are the ones that were present and added to the list but not currently active.

You can then attach your Stage markers to PSN IDs by filling in the “Fixture ID” column. This would allow you to use a lighting fixture as a tracking device. This feature requires that your fixtures are positioned in 3D in your MA project.

Hopefully this’ll get you going

My colleague followed the process and showed the correct result, thank you very much for the help you provided.
