Configuring Models 7401 and 7418 VME Distributed
Asynchronous (VDA/128 and VDA/255) Adapter Boards
When you receive a VDA/128 or VDA/255 board from Data General Corporation, it is
factory configured for board 0 default switch and jumper settings and for DG/UX
revision 5.4.1 or earlier. If the board you are installing is not the first of its type,
you must reconfigure the board for the position that it is to occupy. Tables 2–5
through 2–8 provide switch settings and jumpering information for the VDA/128
board. Tables 2–9 through 2–11 provide jumpering information for the VDA/255
board. For example, to reconfigure a VDA/128 board for board 1 operation, locate
the column for board 1 in Table 2–7 or 2–8 and remove or install the jumpers as
indicated in the rectangles. If your configuration includes more than one board of
the same type, make sure that no two boards have the same board number.
NOTE:
Since the DG/UX operating system recognizes the VDA/128, the VDA/255,
the VAC/16, and the VTC boards by the same device name, syac, no two
asynchronous controller and terminal controller boards can have the same
board number. For example, do not configure both a VDA/128 and a VTC to
board 0; give them unique board numbers.
Figure 2–4 shows the location of the jumpers and the SW1 switch pack on the
VDA/128 board. Figure 2–5 shows the location of the jumpers on the VDA/255 board.
For further information about the boards, refer to HPS VMEbus Host Adapters
Technical Manual for the VDA/128 board and to VDA/255 Host Adapter Technical
Manual for the VDA/255 board.
NOTE:
Verify that the VME controller you plan to install is jumpered
appropriately for the revision of your DG/UX operating system and for the
board position it is to occupy.
Once you have installed the board jumpers, follow the directions in Chapter 3 to
install the VDA/128 and/or VDA/255 board(s) in the card cage.
