2.1 INTRODUCTION
This chapter explains how to configure the DIO module prior to installation in a
VMEbus system
l
locations, switch options, switch locations, and external connector pin descriptions.

2.2 SYSTEM REQUIREMENTS

The DIO module is a double-height VMEbus-compatible
module. As such, the DIO requires a minimum system component configuration for
proper operation. The minimum system requirement can be met by either one of the
following:
A)
A host processor module properly installed on the same backplane as the
DIO; and a controller subsystem module which employs a Data Transfer Bus
Arbiter, a Subsystem Clock driver, a System Reset driver, and a Bus time-
out module. (The XYCOM XVME-010 System Resource Module provides a
controller subsystem with the components listed.)
B)
A host processor module which incorporates an on-board controller sub-
system
Prior to installing the DIO, it will be necessary to configure several jumpers and
switch selectable options. These options are:
1 Module Base Address.
l
2
Whether the module will be addressed in Short I/O Memory or the Standard
l
Memory Space.
3 . Which Interrupt Request Level the module will operate at (i.e., 11-17).
4
Whether the Interrupt Inputs will latch on the rising or falling edge of the
l
interrupt input signal.
5.
Which Address Modifier codes the module will respond to (i.e., 29 or 2D, 2D
only, 39 or 3D, or 3D only).
