CHAPTER 2
HARDWARE CONFIGURATION
2.1 INTRODUCTION
This chapter describes the requirements to integrate the CoreModule/PC as a component within a
wide variety of applications including embedded systems. Information is provided regarding
connector signals and pinouts, external device requirements, interconnection cable wiring, and
board configuration. Also covered in this chapter are the configuration and initialization
requirements of standard and optional onboard devices. Unique to the CoreModule/PC is provision
of a SETUP function, similar to that found in PC/AT's, to store system parameters in a nonvolatile
configuration memory, rather than using jumpers and switches.
Many of the board's functions are software controlled rather than hardware controlled. Therefore,
many features and functions described in this manual assume the presence of the board's standard
ROM-BIOS for their operation. Refer to Chapter 3 for typical software configuration information,
and to Chapter 4 for technical details regarding the board's hardware and software functions.
2.1.1 Interface Connectors
Figure 2-1 shows the location of the board's interface connectors (P1, J2-J5) and configuration
jumper locations. Table 2-1 summarizes the use of each of the board's connectors. Connector
pinouts and signal definitions are provided in the sections of this chapter that cover each connector
interface.
Connector Function Size
P1 PC Expansion Bus 64-pin
J2 Serial Port 10-pin
J3 Parallel Port 26-pin
J4 Utility/Keyboard 10-pin
J5 Power 8-pin
Table 2-1. Connector Usage Summary
The board's I/O connectors consist of dual-row male header connectors. These connectors can be
mated with female header connectors of flat ribbon (IDC) cables, or with discretely wired
connectors.
