EVK2
for GSM/GPRS-Modules
RS232 / USB 1.1 Serial Ports
The communication between the appli-
cation and the Telit module is achieved by
connecting the Asynchronous Serial Inter-
faces (ASC0 and ASC1 ), through a double
stacked standard DB9 connector, that pro-
vides 2 serial communication paths (RS232
protocol, up to 115 Kbit/sec).
As alternative a CMOS HUB, that provides
two-way communication in compliance
with USB 1.1 specification at higher data
rates (up to 1,5Mbytes/sec) is available.
The USB connection is provided by a USB-
A USB-B cable.
The serial port selection is made by
jumpers.
Power Supply Inputs
The EVK2 disposes of different Power
Supply Inputs which allow using it in the
following environments:
■ Automotive setup:
from 5 ÷ 40 Volt source
■ Laboratory setup:
from + 3.8 Volt fixed source
■ Portable setup:
from rechargeable Li-Ion battery pack
General Purpose Inputs / Outputs
With the EVK2, all General Purpose
Inputs/Outputs are made accessible on the
Adapter Boards by a respective number of
pins on the PTH-type connector.
This allows that the applicators can build
their own interface boards which fit best to
their various requirements, e.g. with cus-
tom connectors, cables, relays, LEDs,
Camera etc.
