How to simultaneously turn on two HSB lights on Thor?

Now I have two HSBs, two IMX274 cameras, and a Thor.The connection relationship is as follows.How can I simultaneously activate two imx274 cameras? Are there any existing routines available?

Hello,
The question is for Thor + IMX274 camera, which is currently not supported on JP7.0 release + HSB v2.3, Only Vb1940 camera is supported.
I think the principal of the question is about the fact that both cameras are with default IP address 192.168.0.2 (at least this is what is in the diagram) and for reconfiguring that, we provide the following instructions in the following user guide page: https://docs.nvidia.com/holoscan/sensor-bridge/latest/notes.html#holoscan-sensor-bridge-ip-address-configuration
