4. Installation and Initial Operation 

 

15 

1.  Start your terminal program with the interface parameters 19200 bps, 8 data bits, 

1 stop bit, no parity. 

 
2.  Communication test 

For a first communication test, enter the command “AT” and hit the “Enter” key. 
The reply “OK” indicates that the INSYS GSM small has been successfully installed.  

 
3.  Entering the PIN: 

Attention! When using SIM cards with deactivated PIN query, the PIN does not 
need to be entered. 
Entering the SIM card pin takes place using the command: 
AT+CPIN=“<PIN>“<CR>

 

The input of “” must be observed. 
When a correct pin is entered, OK will be reported back after up to 10 seconds. 
 

4.  Register/Unregister 

After the PIN has been entered, registering at the GSM network is required. 
Register:  AT+COPS=0<CR> 
Unregister:  AT+COPS=2<CR> 

 

After the command has been entered,  “OK” will be reported back after up to 20 

 seconds. 

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

 

Attention! This setting is immediately saved. If it is not changed, independent 
registering takes place after the PIN has been entered (AT+COPS=0 has been 
entered one time). 
If in addition the PIN query of the SIM card has been deactivated, the INSYS GSM 
small registers itself independently at the GSM network, when a SIM card was 
inserted. 
 

5.  Baud rate 

The baud rate can be set to fixed values. 
Examples:   
AT+IPR=9600<CR> 

sets the baud rate to 9600 bps. 

 
AT+IPR=19200<CR> 

sets the baud rate to 19200 bps. 

 
AT+IPR=0<CR> 

sets auto baud. 

 

This setting is immediately saved.
