Right click on BSTV node and choose ‘Set Comp Map’ menu item.Please follow the instruction of the above picture. Left side listed the channels of each machine/unit/cycler, right side are the virtual merge channels container.You can drag and drop all the channels to one interface, or operate them in a bulk/batch, and don’t forget to save what you’ve done. Channels of different units(machines) are successfully merged/mapped into one interface, this is pretty helpful when you want to manager/control many sets of same range testers together.
