at the initial power up after you have changed or upgraded the software card. When you perform an
upgrade, you must execute the following sequence of events exactly as they are stated here:
2. On the DXPCPU–68K circuit board, set DIP switch 8 to its ON position. This step enables...

Up-Loading The Converted Database To The DXP
Connect your computer to the DXP and use VMMI to up-load the translated 10A database to the DXP.
(Note that with VMMI, you do not need the XMODEM communications program that you needed to
store the current database)
