2.4.2 Address Modifier Jumper
The XVME-202 has one jumper that determines which Address Modifier Codes it will
respond to. This jumper is labeled as J2 (see Figure 2-1 for the jumper location).
Jumper J2 determines whether the module will respond to supervisory or to non-
privileged short I/O VMEbus cycles. When jumper J2 is in, the module will respond
to supervisory short I/O bus cycles only. When jumper J2 is out, the module will
respond to both non-privileged and supervisory short I/O bus cycles. Table 2-3
shows the relationship between jumper J2 and the Address Modifiers.
