Troubleshoot issues when using a Poly Trio with the Poly Passthrough software

A customer wants to troubleshoot issues discovered when using the Poly Passthrough software.
  • Ensure you are using at least Poly Trio UC Software 5.9.2.7553 Rev AA or later
  • Ensure you are using at least Poly Passthrough Software 1.0.0.0067 or later
  • Ensure you are using Microsoft Windows 10
Ensure you are using the below configuration (also attached): <?xml version="1.0" encoding="utf-8" standalone="yes"?>
<!--Enable the feature-->
<mr mr.devicePassThrough.usb.enabled="1"/>
<!--integer number equal to 1 + (the number of Visual+ and Visual Pros to pair with)-->
<mr mr.pair.maxDevices="15"/>
<!--Optional Configuration Parameter "1080p", "720p", "540p, or "360p"-->
<!--valid values: 1:"Auto" 2:"360p" 3:"540p" 4:"720p" 5:"1080p-->
<mr mr.passThrough.camera.maxResolution=""/> During the installation, the software creates a Windows Firewall exception:
 
  • Ensure that 169.254.0.0/16 TCP incoming connections are permitted, and Transmit UDP to 224.0.0.200:2001 is permitted.
     
  • Example for a 3rd Party McAfee Firewall:

  • Ensure that the system allows APIPA Address Options as shown >here<
The next step would be to apply the Passthrough_logging.cfg (attached) Example Log when Interface is down or USB cable unplugged: 0113120047|mr |1|00|discoverRxTaskLoop: Packet Rx timeout or error: -1 (11) If there is a Firewall issue the following will appear:
The next message should be:
"Establishing link" means the Pass-through service is waiting for its discovery socket to come up.  "Connecting to Trio" means that the discovery socket is up and the service is sending discovery packets, and is now waiting for trio to request a connection on the TCP link. If the above does not help to troubleshoot this issue please work with your Poly reseller and ensure to provide us Logs from the Trio:
  • Diagnostics > View & Download Logs > Clear
    Replicate the issue
  • Diagnostics > View & Download Logs > UCS Application > Export
  • Provide the Passthrough Software Logs
