Use any terminal emulator software and AT commands to communicate with the 

modem.  

The A3LA-RS is shipped with a CD with a terminal emulator software package called 

SatTerm [2]. NAL Research recommends using SatTerm with the A3LA-RS, because it 

provides a complete reference manual for all AT commands through user-selected 

buttons for quick and easy access. 

14.

 

Verify the following if a data connection cannot be made with the Iridium network: 

a.

 

Antenna has a full view of the sky. 

b.

 

The PIN has been removed from the SIM chip. 

c.

 

Power source provides enough current. 

15.

 

Use the following steps to check if the SIM or the Phone Control is locked: 

a.

 

If using the SatTerm software, open the AT Command Table for the AT+CPIN 

command and click the Read button. If NOT using the SatTerm software, enter the 

command AT+CPIN? 

b.

 

If the response from the A3LA-RS is SIM PIN, then the SIM is currently locked (or 

activated). To remove the SIM, do the following: 

i.

 

If using the SatTerm software: 

1.

 

Enter the SIM PIN code (each SIM is shipped with the default code of 1111) 

in the p box, and then click the Send button. If the PIN code is correct, the 

response from the A3LA-RS is OK

2.

 

Open the AT Command Table for the AT+CLCK command, and then select SC 

from the f box, select 0 from the m box, and enter the PIN code (again the 

default code is 1111) in the p box. Click the Send button. If the PIN code is 

correct, the response is OK

3.

 

The SIM is now removed and ready for use.
