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 125
) 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 83.
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.
