Using the Ethernet interface
The boot loader configures the Davicom DM9000A 10/100BaseTX Ethernet controller.
Connection is made via a dual RJ45 connector. See the sections Ethernet , page 52 ,
and J6 – Ethernet connector , page 80 , for further details.
Using the PC/104 expansion bus
PC/104 modules can be used with the ZEUS to add extra functionality to the system.
This interface supports 8/16 bit ISA bus style peripherals.
Eurotech Ltd has a wide range of PC/104 modules, which are compatible with the ZEUS.
These include modules for digital I/O, analogue I/O and motion control. Please contact
Eurotech Sales (see page 97 ) if a particular interface you require does not appear to
be available as these modules are in continuous development.
In order to use a PC/104 board with the ZEUS it should be plugged into J12 for 8-bit
cards and J12/J13 for 8/16-bit cards. See the sections ZEUS PC/104 interface details ,
page 41 , and J12 & J13 – PC/104 connectors , page 84 , for further details.
The ISA interface on the ZEUS does not support DMA, shared interrupts and some
access modes. See the section PC/104 interrupts , page 42 , for details about PC/104
interrupt use.
The ZEUS provides +5V to a PC/104 add-on board via the J12 and J13 connectors. If
a PC/104 add-on board requires a +12V supply, then +12V must be supplied to the
ZEUS power connector J2 pin 4. If –12V or –5V are required, these must be supplied
directly to the PC/104 add-on board.
Using the ZEUS Modem Modules
The ZEUS Modem modules can be used with the ZEUS to add wireless and GPS
functionality to the system. Various wireless modems are supported to provide packet
data, circuit switched data and voice connectivity on a wireless network. A 12 channel
GPS receiver is also available on the ZEUS Modem module. The ZEUS Modem
module is fitted on the solder side of the ZEUS board (connector J23).
The FFUART serial port of PXA270 is used to communicate with the wireless modem,
and STUART is used to communicate with GPS module. See the sections Wireless
modem and GPS receiver , page 35 , and J23 – Wireless modem/GPS module
interface , page 91 , for further details.
Using the ZigBee Module
The ZEUS ZigBee module can be used with the ZEUS to provide ZigBee
( www.zigbee.org ) and IEEE 802.15.4 compatible wireless connectivity. The BTUART
serial port of PXA270 is used to communicate with the ZigBee module. The ZigBee
module is fitted on the solder side of the ZEUS board (connector J21). For further
details, see sections IEEE802.15.4 / ZigBee module , page 37 .
