ZEUS Technical Manual

Detailed hardware description

 

 

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.
