4. Installation and Initial Operation 

 

 

 

5.  After the device has been reset, the INSYS GSM small registers itself at the GSM 

network. As soon as the device is registered, the LED GSM net changes from 
steady green blinking (600 ms) into green flashing (75 ms on, 3 s off). 

 
6.  Check the field strength of the GSM signal using the button “Detect GSM 

Intensity”. 

 

The response should be a field strength of at least 12 – otherwise the antenna 
location has to be changed. (see also Chap. 5.2). 
 

7.  Establish a connection manually from the terminal window of the program: 

•  Activate the cursor at the end of the terminal window by clicking on it. 
•  Select the test number 22243 (national freenet access number from D1 

and Vodafone) using the command: ATD22243<CR> 

•  INSYS GSM small establishes the connection 
•  After a little while (1 minute max.) the message „CONNECT 9600/RLP“  is 

displayed and the GSM net – DCD LED is orange. 

•  Enter „+++“ to switch into the online command mode. The „OK“ response 

is displayed. 

•  Terminate the connection with the command: ATH<CR> 

 
In general, this connection test is successful. Chapter 4.3.3 shows some 
troubleshooting and diagnosis possibilities.
