2.1 About the GR64
The Wavecom Gx64 family of devices are Quad Band GSM/GPRS Wireless CPU®s
operating in the GSM 850/900/1800/1900 bands.
These products belong to a new generation of Wavecom Wireless CPU®s, and are
intended to be used in machine-to-machine applications and man-to-machine
applications. They are used when there is a need to send and receive data (by SMS,
CSD, or GPRS), and make voice calls over the GSM network.
The GR64 conforms to the European Union (EU) Restriction of Hazardous Substances
(RoHS) directive 2002/95/EC.
The GR64 is available in two hardware variants.
Table 1 lists the hardware features for
each variant. The device is available in two hardware variants:
GR64001. No USB interface or an integrated SIM card holder. VREF is an
output to the application.
GR64002. USB interface and an integrated SIM card holder. VREF is on this
variant an input from the application.
Table 1: GR64 HW Variants
Variant VREF USB SIM Card Holder
GR64001 Output No No
GR64002 Input Yes Yes
Each hardware variant comes in two software variants. One software variant is
designed to be controlled from a micro-controller situated on the host application.
The other software variant offers the option to run applications embedded onto the
Wireless CPU® itself. When using the embedded application version the controlling
script can be run internal to the Wireless CPU®, with or without the use of an external
control.
A typical application, involves a micro-controller and a Wireless CPU®, in which the
micro-controller sends AT commands to the Wireless CPU® via an RS232
communications link.
