AIM104-ETHER Technical Manual Introduction

Handling your board safely

Anti-static handling

This board contains CMOS devices. These could be damaged in the event of static

electricity being discharged through them. Observe anti-static precautions at all times

when handling circuit boards. This includes storing boards in appropriate anti-static

packaging and wearing a wrist strap when handling them.

Electromagnetic compatibility (EMC)

The AIM104-ETHER is classified as a component with regards to the European

Community EMC regulations and it is the user’s responsibility to ensure that systems

using the board are compliant with the appropriate EMC standards.

The opto-isolation provides a good barrier for noise emissions generated by the high

frequency host PC/104 system. The AIM104-ETHER includes additional filter

components on-board to minimise the emissions of high frequency noise. Because of

this, the earth tab supplied with the module must be connected to the chassis of the

system by a good earth wire.

If the electronic system requires input protection against high voltage transients (to

meet CE requirements), it is recommended that an external interface board is located

at the point where the external wiring enters the electronic system enclosure:

Packaging

Should a board need to be returned to Eurotech Ltd, please ensure that it is

adequately packed, preferably in the original packing material.

AIM104-ETHER Technical Manual Getting started

Getting started

Unpacking and connecting up

To begin using the AIM104-ETHER board, follow these steps:

1 Power down your computer.

2 Install the board in a spare PC104 slot.

3 Power up your computer and install the appropriate driver. The driver is usually

supplied as part of the installed operating system.

Initial configuration

The board should be fitted to the PC/104 stack using the mounting kit provided. The

EMC chassis point should be connected to the system chassis using the connector tab

provided and a good piece of earth wire.

Once the board is connected to the host system the Ethernet connection should be

made.

There are a RJ45 connector and a standard AUI connector available.

The pin-out on the AUI connector is arranged so that a crimp connector can be

used. Please check the pinout to make sure that this connection is implemented

correctly. Incorrect connections may lead to damage of the module.

The AIM104-ETHER is supplied pre-configured in jumperless mode, with the I/O

address range of 300 - 31Fh, and interrupt assignments IRQ5. The AIM104-ETHER

configures itself back to Plug and Play mode if the module is to be fitted within a Plug

and Play system (for example Windows 95).

To reconfigure the I/O, IRQ and operating modes please refer to the Software Drivers

section.

The board is provided with a utilities disk containing drivers for a wide variety of

operating systems and netware packages. The disk also comes with a detailed help

utility that guides you through the installation procedure.

The software provided with the AIM104-ETHER is used to configure the board

and to integrate it to third party netware software packages such as Novell

Client32. For specific applications it may be necessary to implement the

Ethernet link in another manner that may require custom written software not

available from Eurotech Ltd.

AIM104-ETHER Technical Manual Overview

Overview

The AIM104-ETHER is based around the Realtek RTL8019AS Full-Duplex Ethernet

controller with Plug and Play functionality. The RTL8019AS integrates the RTL8019

Ethernet controller core and 16 Kbyte SRAM in a single chip. A serial EEPROM is used

to store resource configurations and ID parameters.

REALTEK RTL8019AS Ethernet controller

The Realtek RTL8019AS is a highly integrated Ethernet controller that is used on the

AIM104-ETHER to implement Plug and Play NE2000 compatibility and full-duplex

operation. The full duplex function enables simultaneous transmission and reception

on the twisted pair link to a full duplex Ethernet switching hub. This feature increases

the channel bandwidth from 10 to 20 Mbps.

PnP and jumperless modes

The Microsoft Plug and Play function frees the user from setting the AIM104-ETHER

configurations such as I/O and memory address and IRQ, etc. For certain applications

Plug and Play cannot be used (i.e. use with the Eurotech Ltd TARGET processor

range). For cases such as these the RTL8019AS also supports jumperless operation.

In jumperless mode the configuration parameters can be configured using the

RSET8019.EXE utility provided on the utilities disk.

AIM104-ETHER Technical Manual Overview

I/O addressing

The AIM104-ETHER supports 16 base I/O addresses. The I/O address is automatically

configured in a Plug and Play environment. In a jumperless system the module can be

configured to any of the available address ranges shown below:

I/O address range - 200 - 21Fh

220 - 23Fh

240 - 25Fh

260 - 27Fh

280 - 29Fh

2A0 - 2BFh

2C0 - 2DFh

2E0 - 2FFh

300 - 31Fh *

320 - 33Fh

340 - 35Fh

360 - 37Fh

380 - 39Fh

3A0 - 3BFh

3C0 - 3DFh

3E0 - 3FFh

* The AIM104-ETHER is supplied pre-configured in jumperless mode with a default I/O

address of 300h.

Interrupts

The AIM104-ETHER can be software configured to generate interrupts on one of eight

PC/104 interrupts. With Plug and Play systems this is done automatically. With

jumperless operation the IRQ number can be set using RSET8019.EXE.

Available IRQ’s : IRQ2/9, IRQ3, IRQ4, IRQ5 *, IRQ10, IRQ11, IRQ12 and IRQ15

* The AIM104-ETHER is supplied pre-configured in jumperless mode with the default

IRQ setting IRQ5.

AIM104-ETHER Technical Manual Overview

EMC chassis point

Two EMC chassis points are provided on the module using the PC/104 mounting

holes. To minimise high frequency noise transfer the earth tab supplied with the

module must be connected by a good earth wire to the chassis of the system.

Power connections

The AIM104-ETHER needs +5v and GND to operate. It also needs +12v if the 10-

BASE-T connection is being used. These should be supplied to the board via the

PC/104 connector. Ensure that the connections for all necessary voltages are made to

the baseboard or processor module (for example SBC104, ELAN104).

Boot ROM

A boot ROM can be fitted to the AIM104-ETHER so that it can boot directly from the

network instead of from floppy or hard drive. The socket allows 27C256 parts or

equivalent to be fitted.

The utilities disk contains sample ROM files and accessories that can be used to

generate a customised ROM file that can be blown into the boot ROM part. These

accessories contain a ROMSUM utility that can be used to adjust the size of the ROM

file to suit the boot ROM fitted.

PC/104

The AIM104-ETHER module can be attached to either an 8-bit or 16-bit PC/104 bus.

The module automatically detects whether it is connected to an 8-bit or 16-bit system.

Status LED’s

There are three LED’s on the module. These provide a visual indication of the status of

the module include TX, RX and LINK. The red LINK LED flashs if there are any

collisions on with the transmission network. If this happens the connections to the

AIM104-ETHER should be checked. The corresponding colors for the LEDs are as

below:

• GREEN - TX

• YELLOW - RX

• RED - LINK

The header PL2 allows external LEDs to be connected to the board. Please refer to the

appendix for connection details.
