2.4.2 Address Modifier Jumper
The DIO Module 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.
