Set Base Address Using Jumper Block W1
Move the jumper to the side labeled 1 to select a logical one for the corresponding address bit, or
to the side labeled 0 to select a logical zero. Figure 3-3 shows the configuration for a base
address 2000 (hex), which is the default address configured at the factory.

Set Base Address Using Compare Address Lines
Another method of setting the base address is to use the compare address lines located on the P2
connector. The jumpers on jumper block W1 must be removed and TTL-compatible voltages
must be applied to pins CA9 through CA15 on the P2 connector when using this method. Refer
to Table 3-4 for the pin assignment numbers of the P2 connector. A scrambler card and interface
cable assembly (described under Cabling later in this chapter), available from National
Instruments, are necessary when setting the base address of the board using this method.
