Note After installing DRAM on the VXI-MXI-2, you need to enable the memory through
Measurement and Automation Explorer (MAX).

Table 5-1 lists the SIMM types you can use. You can use 32- or 36-bit
SIMMs because DRAM parity is not required. Because the VXI-MXI-2
supports only one organization at a time, all SIMMs installed must be of the
same type. Use Bank 0 first when installing the SIMMs, and use Bank 1
when you need to install a second, matching SIMM. As shown in Table 5-1,
you can install up to 64 MB. The VXI-MXI-2 supports DRAM speeds of
80 ns or faster.
Use switch S6 to select the size of each SIMM. If the SIMMs are 4 M × 32
or larger, set S6 to the OFF setting as shown in Figure 5-10a. For SIMMs
smaller than 4 M × 32, use the ON setting as shown in Figure 5-10b.

Refer to Table 5-1 for how to adjust the switch (ON or OFF) for all
supported DRAM configurations. Many of the DRAM options are
available from National Instruments.
