Multi-camera configurations for ZED Link Duo on AGX Orin

[Lukas]

Dear Stereolabs-Team

We are currently using the following setup:

• NVIDIA Jetson Orin AGX Dev-Kit (running on 36.4.7)
• Zed Link Duo Capture Card
• 1 x ZED X One 4K
• 1 x ZED X Mini

When trying to connect both cameras, your documentation ( ZED Link Duo on AGX Orin - Stereolabs ) clearly specifies that the ZED X One 4k must only be connected to either the port #0 or #2 and that only 1 camera should be connected to 1 group.
These recommendations, however, did not work for us and we were able to only detect one of the two simultaneously connected cameras.
We then moved forward and acquired the following table, showing which port combinations actually did work out for us, meaning that we were able to detect and use both cameras at the same time, marked with “Yes”:

I now have the following two questions:

1. Is there a way to find out why we have this discrepancy between your documentation and what we are able to reproduce?

2. IF we don’t use either port #0 or port #2 for the ZED X One 4k, what is the following implication according to your specs? Like is there just an impairment, or do you expect the camera(s) to just not work at all?

Best regards and thank you in advance,

Hi @Lukas
What version of the ZED X Driver and ZED SDK are you using?

[Lukas]

Hi @Myzhar

The Zed Driver has version 1.3.2 and the SDK has version 5.1

[Myzhar]

You must update to ZED X Driver 1.4.x and SDK v5.2.x to leverage the latest features.

Okay sure, we’ll update again.
But can you make any comment on my question? Since it should still be applicable to the versions currently in use….

The documentation always refers to the latest version of the ZED X Driver. So in this moment, the information is coherent with the behaviors of the ZED X Driver v1.4.1.

If a ZED X One 4K is connected to a wrong port, driver probe will return an error (see dmseg) and tells to switch to the right port. This is only valid for ZED X Driver >=v1.4.1.
