Hi IGSTK-USERS<div><br></div><div>We want to inform you about a problem that we found.<br><div><br></div><div>Our team has been working the last week with IGSTK and NDI Polaris Spectra Tracker.</div><div><br></div><div>It has been difficult to get the tracker to work with IGSTK. The problem we found using the igstkPolarisTrackerTest2 is that IGSTK do not connect to the tracker.</div>
<div>When we run igstkPolarisTrackerTest2 in cmd with the proper inputs (igstkTests.exe igstkPolarisTrackerTest2 Logger.txt 8700340.rom 3) we get the next output on the terminal.</div><div><br></div><div>AC = 5</div><div>

<div><br></div><div>We try this solution and found that it work.</div><div><br></div><div>We have only probe this with one tool, we still have to do some tests with more than one tool.</div><div><br></div><div>So, our questions are. Is this a real problem with all users or its some isolated problem regarding our configuration? Do you knew about this problem? Is there another solution to fix it?</div>
