NTC 3000 Series – M2M Serial Modem
43
General Operation
Upon powering up, the application subscribes to the SMS service and sets up customized AT commands. It then reads the configuration from FLASH. If the device is configured in
normal modem mode (AT+PAD=0), the application will not start GSM or GPRS initialization, TCP or UDP preparation routines.
When TCP/IP has been set up, an IP address will be issued to the NTC-3000. The application can then switch to one of the following modes:
TCP client mode
TCP server mode
UDP client mode
The application can switch to any of these modes by AT command or remotely through SMS. The serial port can be initialized while GSM/GPRS registration in progress. If the flash
configuration area is empty, the default parameters are loaded. The default parameters are as follows:
Serial Port
Baud Rate: 115200
Data Bits: 8
Parity: none
Stop Bit: 1
PDP profile
APN :
User:
Password:
TCP Client
Server :
Port: 1516
The NTC-3000 default running mode is with PAD disabled.
