I am about to setup & converge a Barco Data 1100 & have both installation and owners manuals.Some things are not clear in the manuals: Since convergence data is stored in each block, 1. Is it desirable to delete all existing blocks so as to start fresh? 2. Will the convergence data be stored in a new block and if so, how does the projector know to connect to that over the others stored? 3. If I connect a second input to the proj. is it necessary to go through the whole setup again to get the convergence data stored with that input? or is "Copy a Block" somehow used to transfer this data? Any help would be appreciated, the manuals don't address these questions.
