TRACKER

Link aggregation is used to describe various methods for using multiple parallel network connections to increase throughput beyond the limit that one link (one connection) can achieve. Link aggregation is supported in Tracker 1.3+, Nexus 1.8.5+, Blade 2+.

When setting up Link Aggregation ensure that you have the correct Network cards (Intel i340-T4 or the Intel i350-T4 cards) installed on your capture PC. Once you have the correct Network card(s) follow these steps:

1. Make sure your three network ports have fixed IP addresses 192.168.10.1, 192.168.10.2 and 192.168.10.3. A maximum of nine NICs are allowed (192.168.10.1 – 192.168.10.9 inclusive).

2. Connect the 192.168.10.1 and 192.168.10.2 ports to one Giganet/Power over Ethernet switch (POE) and 192.168.10.3 to the other Giganet/POE. You will need an extra cable connecting your Giganets/POEs.

3. Run Tracker/Nexus/Blade, set your workspace to Camera and select all the cameras in the System pane (you will need to expand Vicon Cameras). Please do note that there might be slight differences between the three applications.

4. Turn the Giganet/POE connected to 192.168.10.3 off then select all the cameras that just went red in the System pane.

Select the Destination IP Address drop-down and select 192.168.10.3.

5. Select the remaining (green) cameras then scroll down their Properties, select the Destination IP Address drop-down and select 192.168.10.2.

6. Turn the Giganet/POE connected to 192.168.10.3 back on. Select all the cameras in the System pane.

Save your System configuration.

Vicon Core Software will also install documentation/help guide when you install the software.

Once installed, launch the software and select Help > View Installed Help

The following software will install Help:

The Virtual-Reality Peripheral Network (VRPN) is a library that provides an interface between 3D immersive applications and tracking systems used for Virtools. Vicon Tracker 3 has a built-in VRPN server that will stream data natively into these applications or will allow for the development of simple interfaces using VRPN.

Virtools, a commercial application, has support for VRPN and can be configured to connect with Vicon Tracker as follows.

A full VRDevice.cfg file is included below.

Note

Head@TrackerPC is the way Virtools connects to the VRPN server within Tracker. The format is object_name@PC_Name. This configuration file will look for an object called “Head” on the Tracker server called “TrackerPC.”

=======================================
vrpnTracker_0 Head@TrackerPC
neutralPosition_0 0.0 0.0 0.0
neutralQuaternion_0 0.0 0.0 0.0 1.0
axisPermute_0 0 2 1
axisSign_0 1 1 1
trackerScale_0 1
TrackerGroup_0 T0:0:6
=================

This VRDevice.cfg also contains other directives that:

• Map the Vicon coordinates properly to the Virtools coordinates:

axisPermute_0 0 2 1
axisSign_0 1 1 1

• Add a tracker group with:

TrackerGroup_0 T0:0:6

To complete the process, do the following:

• Add the VRPN settings to a VRPack.cfg file, which is in the same folder as the .cmo. That way it can be tested with Virtools Dev.
• For versions of Tracker before 1.2 in the composition, activate the Use Scale option and change the value of

trackerScale_0

in your VRDevice.cfg file to 0.001 (converts Vicon mm to Virtools m).

For a full description of any of these configuration options, please refer to the Virtools documentation.

If the cameras continue to connect with the previous version of software but don’t in the latest version then the software is probably being blocked by the Windows Defender Firewall. Although Vicon officially specifies that the Firewall should be turned off completely to ensure unobstructed communication with the cameras and connectivity devices, sometimes institutional protocols mandate it to be turned on. If this is the case:

1. Go to Control Panel > Windows Defender Firewall and click on Allow an app or feature through Windows Defender Firewall.
2. Scroll down the list of applications to look for the instance of Vicon software (Vicon Nexus, Vicon Tracker, Vicon Shogun, Vicon Evoke).
3. Select the application and click Details to ensure it refers to the version you are trying to run.
4. Click on Change Settings to enable the networks (Domain, Private, Public) that match those of the previous version. If this option is disabled then please contact the system’s administrator or your institution’s IT personnel for assistance.
5. Click OK.
6. Restart the Vicon software.

If this does not resolve the issue then please contact Vicon Support.
