In the right part of the dialog you see all available data sources, modules and signals as configured in the I/O manager (Inputs) before.

You can assign signals to groups easily by drag and drop.

A signal can be assigned to multiple groups.

You may select multiple signals with the usual key-mouse-combinations <Ctrl> + mouse click or <Shift> + mouse click and assign them together to a group.

You may even assign entire modules to a group when you select the module name and drag it into the group.

By using the <Swap order> button, you can reverse the order of the signals within the vector. The group must be selected (highlighted) to do so. If you like to change the position of one or more signals, select the signal(s) in question and use the up/down arrow buttons in the group tree window. Furthermore, cameras from an ibaCapture module can be added to groups as well.
