This accessory for the MC70 series of terminals
provides GPS capability. The unit attaches as a sleeve
around the MC70. The mechanical design of the module
enables the attachment to remain compatible with
existing MC70 accessories such as the desktop charge
cradle and the car charger. The USB port from the MC70
is brought through to the docking connector on the
bottom of the GPS sleeve to provide ActiveSync
connectivity to the MC70.
The GPS unit uses the SiRFStarIII chipset and has an
integrated antenna. Communication with the MC70 terminal
is over the serial port. By default, communication uses
the NMEA-0183 protocol allowing immediate operation with
standard software packages. The unit can be configured
for baud rates up to 57600baud. SiRF protocol may be
used in place of NMEA.
