I65/I56I HARDWARE DESCRIPTION VERSION 

1.00 

8  First steps to make it works 

The quickest way to get first results with the I56/I56i embedded 
GSM/GPRS module is to operate with the GSM-EVAL-KIT which is 
available by FALCOM upon request. It saves design, time and reduces 
“Time-to-Market” period. For more details about the FALCOM GSM-
EVAL-KIT, refer to the chapter “

GSM Evaluation Kit (GSM EVAL-KIT)

”.  

NOTE:

   The GSM/GPRS module I56/I56i are compatible to the I2D 

module as far as the pin-out on the 50-pin board-to-board 
connector is concerned. By evaluating the I56/I56i, an I2D 
adapter board is required to perform the connection between the 
I56/I56i and GSM-EVAL-KIT. This applies for the users who 
already have an adapter and a GSM-EVAL-KIT. For other users 
they have to purchase one. 

8.1  Minimum set-up connection 

This section and subsections below describes the minimum hardware 
connection of I56/I56i module to get started if the users do not use the 
GSM-EVAL-KIT. 
As a minimum, to set-up a connection between your PC and the I56/I56i, it 
is necessary to connect the following interfaces to operate the I56/I56i 
properly. Please follow step-by-step the instructions below. The figure 
below shows in a visual form the connection of the I56/I56i hardware 
interfaces.  
 

 

8.1.1  Mounting the I56/I56i 

The I56/I56i contains two holes for mounting screws. The module can also 
be assembled to various applications without using the screws.  

8.1.2 Antenna 

interface 

The antenna must be located on the places where the signal strength is 
sufficient. Maybe a mobile phone is required to be used to verify the best 
location for the I56/I56i connected antenna.
