INTRODUCTION
...............................................................................................................
The PCFW-104-ETH is a 16-bit Ethernet Bridge interface module. The module is compliant
to Ethernet II and IEEE 802.3 10-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, Serial to Ethernet
Bridge and a FreeWave FGRM-510X005 TTL Level 900 MHz Spread Spectrum Radio. Option-
ally a 1.3 GHz P501X005 Military/Export only radio can be fitted.
The Serial to Ethernet Bridge is a highly integrated ASIC that combines LAN and WAN subsys-
tems to achieve a full Ethernet remote bridge. It automatically learns the MAC addresses on
the LAN it is connected to, and forwards only the frames destine for another LAN. This bridge
is placed between the RT8019 Ethernet controller and the FGRM Spread Spectrum radio to
form a highly integrated and compact Ethernet bridge for embedded applications and is fully
compatible with the FreeWave FGR-115RE Ethernet Bridge which makes an ideal master for
embedded systems networking.
The PCFW-104-ETH 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 sta-
tion automatically from a server making floppy and hard drives unnecessary.

Getting Started, Initial Configuration
The board should be fitted to the PC/104 stack. The PCFW-104-ETH is supplied pre-config-
ured in jumperless mode, with the I/O base address of 0x340 and interrupt assignment of
IRQ5. 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 ,
HELP8019.exe, that will guide you through the installation procedure.
