Hi Alex,

Thank you for the reply.

> We went through the settings in the GenICam Browser, and saved them as a user set on both of the configured devices.

Yes, that’s the procedure that I wanted to ask you. Thanks.

> The device on port 1 doesn’t run, either by itself or when tried with the device on port 0.

Could you show me the exact code, please? It’s not necessary to show the whole program but I would like to know the lines that give you the expected result.

> Can I install CVB 14 alongside 13?

Please forget about it because I do not want to mess this up; I just wanted to make sure you can reproduce the original issue on CVB 14.

Last but not least, I would recommend knowing the difference between Python threading and multiprocessing because you may find one works for a demo but it does not mean the concept works for your final application because the difference can be very critical; then you will need to go back and start developing it from scratch. (I recommend you check the script that I recently posted on [another post](https://forum.commonvisionblox.com/t/cvb-python-multi-camera-acquisition-software-trigger/1782/11).)
