7. Communicating with Modem
7.1 Serial Interface mechanism
Customers can interface the modem through main (DB9 Connector). Following are the serial interface format
used in Calixto GL86x modem in below figure:
The CST-GL868-MODEM is built around Telit GL86x module. Customers can follow all the programing
mechanism suggested by Telit.
7.2 Communication Software
Customer can use any serial terminal program in PC to communicate with modem. We have used “rsterm” for
our development and test. Below figure shows typical screen shot of rsterm.
Customer can use either AT commands or program the GL86x module with Python script defined by Telit.
