1 Warning AIM104- ETHER Handling This board contains static sensitive devices. Observe anti-static precautions at all times. Unpacking and installation of the board should be undertaken in an anti-static working area. Electrostatic Handling The AIM104-ETHER contains CMOS devices which could be damaged in the event of static electricity being discharged through them. At all times please observe anti-static precautions when handling the board and always unpack and install the board in an anti-static working area. Introduction The AIM104-ETHER is a high performance 16-bit Ethernet interface module. The module is compliant to Ethernet II and IEEE Base-T and is compatible with Novell NE2000 in both 8-bit and 16- bit operation. The module includes a built-in 10-Base-T transceiver and RJ-45 connector. An AUI connector supports external transceivers for 10-Base-2, 10-Base-5 and 10-Base-FOIRL, etc. The AIM-104-ETHER is supplied with a utilities disk that contains drivers for a wide variety of networks and operating systems. An optional boot ROM lets you boot a remote PC/104 station automatically from a server making floppy and hard drives unnecessary.

2 J604 AIM104-ETHER Getting Started 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. Warning: 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 Fh, and interrupt assignments IRQ5. The AIM104-ETHER will configure itself back to Plug and Play mode if the module is to be fitted within a Plug and Play system (e.g. 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 will guide you through the installation procedure. Note: 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 which may require custom written software not available from Arcom. Page 2

3 J604 AIM104-ETHER 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. Block Diagram REALTEK RTL8019AS Ethernet Controller The Realtek RTL8019AS is a highly integrated Ethernet controller which 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 can not be used (i.e. use with the Arcom 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. Page 3

4 J604 AIM104-ETHER I/O addressing The AIM104-ETHER supports 16 base I/O addresses. The I/O address will be 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 Fh Fh Fh Fh Fh 2A0-2BFh 2C0-2DFh 2E0-2FFh Fh * Fh Fh Fh Fh 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. 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 base board or processor module (e.g. SBC104, ELAN104). Page 4

5 J604 AIM104-ETHER 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 a 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 will flash if there are any collisions on with the transmission network. If this happens the connections to the AIM104-ETHER should be checked. The corresponding colours 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. Links Default Link Position User Configuration Diagram Page 5

7 J604 AIM104-ETHER Software Utilities Disk The utilities disk provided with AIM104-ETHER contains: Drivers for a wide range of Netware packages and OS s Ethernet Controller and EEPROM Configuration utilities Boot ROM utilities Configuration Software There are two main utilities provided. RSET8019.EXE is used to configure the Realtek RTL8019 Ethernet Controller. This can be used to set the I/O address, IRQ, select jumperless or PnP mode, and perform several function tests. PG8019.EXE is used to program the EEPROM device on the board. This is done before despatch from Arcom and should not be done unless the EEPROM becomes corrupted. Drivers Drivers are provided for a wide range of Netware packages and OS s. To install the drivers refer to the documentation for the Netware/OS and to the help utility HELP8019.EXE. There is a detailed description on how to install all drivers within this file. Boot ROM Utilities The utilities disk contains complete documentation, sample ROM files and build utilities on how to generate and implement the Boot ROM. This will allow the system to boot from the a remote ethernet host instead of the local floppy or hard drive. Page 7
