Configuring a Model 7425 VME Terminal Controller (VTC)
Board
When you receive a VTC 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 2–13 through 2–14
provide jumpering information for the VTC board. For example, to reconfigure a
VTC board to board 1, locate the column for board 1 in Table 2–13 or 2–14 and
remove or install the jumpers as indicated in the rectangles.
NOTE:
If your configuration includes more than one board of the same type, make
sure that no two boards have the same board number. The DG/UX
operating system recognizes VTC, VDA/128, VDA/255, and VAC/16 options
by the same device name, syac. Make certain all the asynchronous and
terminal controller boards in your system have unique board numbers.
Figure 2–6 shows the location of the jumpers on the VTC board. For further
information on the board, refer to the VMEbus TermServer Controller (VTC)
Hardware Technical Manual.
NOTE:
Verify that the VME controller you plan to install is jumpered
appropriately for the current revision of your DG/UX operating system.
Once you have installed the board jumpers, follow the directions in Chapter 3 to
install the VTC board(s) in the card cage.
