Troubleshooting

No images are streamed from the camera

When the camera connects to the host machine but there are no images being streamed from there camera, it generally means there is an issue with the host machine’s network configuration.

See details on setting the host machine’s MTU to ensure your host machines MTU is configured correctly

AutoDetect not working

  1. Check physical connectivity (ensure link light present, double check network/power cables)

  2. Check if a link is detected on host machine

  3. Check if host machine is able to ping cameras expected IP

  4. Check that host machine only has one configured IP per interface/interfaces are in automatic mode

Note

On some OS including Ubuntu, it is possible to configure one interface with multiple IP. This will prevent the network auto-configuration from working properly.

Cannot set camera MTU

  1. Ensure host machines MTU is greater/equal to requested camera MTU

  2. Ensure the network interface supports the requested MTU. Some USB-Ethernet interfaces and embedded computers do not support MTUs greater than 1500

See details on setting the host machine’s MTU for more information

Cannot set requested FPS/setting is reverted

  1. Ensure a valid FPS/resolution/disparity combination is being requested

Note

Maximum FPS is a function of the 3 above parameters. Generally, in 960x600 resolution, all disparities are supported up to 30FPS, while in 1920x1200, 9FPS is a reliable maximum for all disparities, but greater may be achieved at lower disparities.

Download Debug Logs

The MultiSense offers the ability to download encrypted debug logs on firmware newer than v6.0. These logs are used by the Carnegie Robotics support team to remotely triage potential issues with the MultiSense.

The follow commands can be used to download logs from a MultiSense at the default 10.66.171.21 IP address.

echo "{\"log_file_name\":\"multisense_log\"}" > log_request.json;

curl -T log_request.json tftp://10.66.171.21;

curl -O tftp://10.66.171.21/multisense_log.tgz

Note

It can take a few seconds for the camera to create the output debug log file. Please wait at least 5s after the log_request is sent to the camera before attempting to download the debug log file.

Logs should be uploaded to the support portal along with a description of the issue.
