Wireless support
The ZEUS can support various wireless modems, GPS functionality and an
IEEE802.15.4 / ZigBee wireless sensor network interface. This is achieved using two
optional add-on modules. GPS and cellular functionality are integrated on a single
module (ZEUS Modem-n) while the IEEE802.15.4 / ZigBee port is provided by a
separate module. Other cellular wireless modems such as EVDO, EDGE or satellite
modems may be supported via this interface. Please contact Eurotech Sales (see page
97 ) for more information about the available options.
ZigBee Module Wireless Modem and GPS
Wireless modem and GPS receiver
Various wireless modems are supported to provide packet data, circuit switched data
and voice connectivity on a wireless network. ZEUS also provides complete GPS
functionality including position, velocity and time (PVT). The ZEUS modem module is
fitted on the solder side of the ZEUS board (connector J23).
The wireless modem is driven by the FFUART serial port (within the PXA270), while
the GPS module uses the STUART serial interface (Rx/Tx only). For the connector
details, see the section J23 – Wireless modem/GPS module interface , page 91 .
There are also a number of control/status GPIO signals connected to J23. They can be
accessed through a GPIO Expander MAX7313. See the section On-Board GPIO
expanders pin assignments , page 29 .
