Real Sense Viewer Software Not Detecting Camera #13034

Closed Nataraj-github closed 3 months ago

Nataraj-github commented 3 months ago

Hello, I am using the L515 camera and the Intel RealSense Viewer v2.55.1 on a Windows 11 PC. It gave me this error message <device-model.cpp:442 - Exception caught trying to detect presets: cannot parse device name from 'Platform Camera'> when I connected the device and started streaming. Attached is images of the error screens.

Hi @Nataraj-github Support for the L515 camera model was removed in 2.55.1. You should be able to use your L515 with the Viewer if you use the Intel.RealSense.SDK-WIN10 installer file to install the 2.54.2 version of the SDK. Using the installer file will automatically replace your 2.55.1 version with 2.54.2 so you do not need to uninstall 2.55.1.

The 'Platform Camera' option usually accesses non-RealSense RGB cameras such as the built-in webcam on a laptop. It does not work with all RGB cameras. For example, if may be able to display the RGB feed from the webcam on one laptop but not on a different make of laptop.

Hi @MartyG-RealSense,

The cable given with the LIDAR l515 is very short in length, so can it be used with other lengthy cables, at least a meter in length? If yes do you have any suggestions? Will it affect its performance? Please let ,me know.

MartyG-RealSense commented 3 months ago

Yes, you can use long cables with RealSense cameras. For cable lengths longer than 2 meters though it is important that the cable is a high quality one that is also designed for data transfer and is not an inexpensive cable meant only for device charging. Otherwise there could be performance degradation and disconnections.

For very long distances, using a cable that contains active repeater components to boost the signal is recommendable. The company Newnex supply RealSense-validated cables that are of equivalent high quality to the official 1 meter cable supplied with the camera.
