We have some OSP5000 and 5020 controls which have two bubble memory partitions. The default memory path seems to be pointed at BB1 all the time for file read. One of our machines has a very large BB1 and small BB0 so that's no problem. The other machine has a very small BB1 and large BB0. Okuma said they don't know why and can't tell me how to get around this. We basically want to Read files into the BB0 memory area. Does anyone know how to do this? We've tried pointing the directory at BB0 but it switches back to BB1 when we change to the PIP screen. Any information would be greatly appreciated.
