7.3 Checking the communication with the modem
Once the modem is connected, you can check communication between the RB600
terminal and the PC using Telit AT Controller available here:
http://teleorigin.com/file_upl/pliki/1/Telit_AT_Controller.zip
Alternatively, you can use any Terminal program. Configuration of the DTE (port COM)
should be as follows:
Bits per second: 115200 bps,
Data bits: 8,
Parity: None,
Stop bits: 1,
Flow control: hardware.
To communicate with the modem, use software such as Hyperterminal (AT commands) or
use the attached Telit AT Controller.
Using a communication software such as Hyperterminal, enter the AT and push 'enter'
button. The response of the terminal should be 'OK' displayed in the Hyperterminal
window.
If the connection with the modem cannot be established do the following:
Check if the modem is connected with your PC via RS-232 or USB.
Check the configuration of the COM port.
Examples of AT commands:
ATE1 enables modem echo function,
AT+CGMI modem answers “Quectel” when the connection is OK.
AT+CPIN? shows the current status of the SIM card
AT+CPIN=xxxx enter your PIN, where 'xxxx' are digits
AT+CSQ to verify received signal strength
