INSTALLATION
2.1 INTRODUCTION
This
chapter
explains how to configure the DIO module prior to installation in a
VMEbus system
l
Included in this chapter is information on jumper options, jumper
locations, switch options, switch locations, and external connector pin descriptions.
2.2
SYSTEM
REQUIREMENTS
The DIO module is a double-height VMEbus-compatible digital (TTL level) input/output
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
l
Prior to installing the DIO, it will be necessary to configure several jumpers and
switch selectable options. These options are:
1
l
2
l
Module Base Address.
Whether the module will be addressed in Short I/O Memory or the Standard
Memory Space.
3 . Which Interrupt Request Level the module will operate at (i.e., 11-17).
4
l
Whether the Interrupt Inputs will latch on the rising or falling edge of the
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).
2.3 MAJOR COMPONENT LOCATIONS
The components relevent to installation are shown in Figure 2-l.
