4. Installation and Initial Operation 

Attention! To avoid problems due to undefined settings of baud rate and data 
format, we recommend to deactivate the auto baud function, and to select a fixed 
baud rate. 

 

6.  Data format 

The data format can be set to fixed values. Example: 
AT+ICF=5,1<CR> 

sets the data format to 7E1 (7 data bits, parity even, 1 stop 

bit). 
AT+ICF=3<CR> 

sets the data format to 8N1 (8 data bits, no parity, 1 stop bit). 

 
For the first parameter, the following inputs are possible: 

1  8 data bits, no parity, 2 stop bits Æ 8N2 (no second parameter required for 

this setting) 

2  8 data bits, 1 stop bit, the second parameter determines the parity 

3  8 data bits, no parity, 1 stop bit Æ 8N1 (no second parameter required for 

this setting) 

4  7 data bits, 1 stop bit, the second parameter determines the parity 

 

The second parameter determines the parity (when available): 

O Odd parity 
E Even 

parity 

N No parity 

 
The following settings are possible: 
8N1, 7E1, 7O1, 8E1, 8O1, 8N2 
 
Attention! 

The setting of the data format must be saved with AT&W.  
If auto bauding is active (AT+IPR=0), this also applies for the 
recognition of the data format (except 8N2). 

 

Perform a manual connection from the terminal program: 

a.  Select the test number 22243 (national freenet access number from D1 

and Vodafone):   ATD22243<CR> 

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

displayed and the GSM net – DCD LED is orange. 

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

is displayed. 

e.  Terminate the connection with ATH<CR>.
