General Operation
PAD mode
Upon powering up, the application gets an IP address from the network, subscribes to the SMS service and sets up
customized AT commands. By default, the device boots up in PAD=0 mode which is also a configuration mode. To
log in to this mode, the default username is root and password is admin. The device can be set to PAD modes (TCP
Client, TCP server, UDP Client, UDP Server mode), PPP mode or PSTN mode. If the configuration is saved, the NTC100 will start in the configured mode upon next boot.
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
Serial Mode: RS232
PDP profile
APN: telstra.internet
User:
Password:
Server configuration
Server:
Port: 1516
The NTC-100 default PAD mode is with PAD=0.
PPP mode
In PPP mode, a DTE can dial the NTC-100 with an AT dialling command and create a PPP connection between the
DTE and the NTC-100. An IP address will be assigned to the DTE and it can talk to remote servers.
PSTN mode
In this mode, the NTC-100 application creates a tunnel between the DTE and the modem. The DTE can directly talk
to the device module with AT commands.

Configuration through SMS
The NTC-100 can be configured through the serial port with AT commands or remotely through SMS messages. In
order to use SMS commands, the AT+SMS_DIAGNOSTICS=1 command must be issued through the AT command
port.
When configuring the NTC-100 using SMS messages, all the messages must be prefixed with a password and without
a space after it, for example, “1234get status”. When “set” and “execute” SMS commands are received, the NTC100 sends an acknowledgment reply message when the command has been implemented.
The following is a list of SMS commands that may be used, along with a description of their usage:
execute clear
Instructs the NTC-100 to erase all stored SMS messages.
execute factory_reset
Instructs the NTC-100 to reset to factory default settings, as per the “AT+FACTORY_RESET” terminal command.

The NTC-100 is a DCE (Data Circuit-Terminating Environment), so the RTS (Ready To Send) signal is received by the
NTC-100 and the CTS (Clear to Send) signal is transmitted with flow controlled from both ends.
The DCD (Data Carrier Detect) line is permanently set to one state, i.e. in the high state at the connector, GND at
the chip.
Electrical Specifications
A suitable power supply is available on request or via direct purchase from the NetComm Online shop. It is
recommended that the NTC-100 be powered using a 12VDC/1.5A power supply.

Garbage text usually indicates that the port speed has been changed.
Note – Please refer to the AT Command reference document for more information on enabling remote access to the NTC-100.
The NTC-100 LEDs are not lighting up
Verify that the NTC-100 is connected to an appropriate power supply and that an active SIM has been
inserted.
Power cycle the NTC-100 by removing the power supply for 15 seconds and then reconnect it.
The LED is not turning on
Verify that the NTC-100 has sufficient signal strength to connect by checking the available signal
strength via the appropriate AT command.
Note – Please refer to the AT Command reference document for more information on signal strength.
I am receiving an ‘ERROR’ response from the NTC-100
Verify the AT command you are utilising has the correct syntax specified.
I am receiving an ‘ERROR (##)’ response from the NTC-100 with an error code that I don’t understand

FAQs
Q: Is the NTC-100 a serial modem?
A: The NTC-100 is able to operate as a serial modem, however it is also so much more. It is also able to perform the
following functions:
Creating a TCP server
Creating UDP sockets / TCP clients and a TCP server
Creating a PING session
Creating an FTP session (upload and download files)
Connect to a remote SMTP server
Connect to a remote HTTP server
Email sending / receiving
Sending an MMS with one or multiple recipients
Q: What are the port settings required for the NTC-100?
A: The NTC-100 uses auto-bauding to determine the current communication port settings. This occurs when the first
A or AT is sent to the NTC-100. Generally, a port speed of 115200, 8 data bits, 1 stop bit, no parity and hardware
flow control should be fine. Garbage text usually indicates that the port speed has been changed.
Q: Does the NTC-100 support circuit and packet switched data?
A: The modem inside the NTC-100 supports packet switched and circuit switched communications methods.
Q: Can the micro USB port be used to connect to legacy devices?
A: No. The micro USB port requires Windows XP, Windows Vista, Windows 7, Windows 8 or Windows 10
operating systems.
Q: Why can’t I connect an Ethernet (RJ45) cable to the NTC-100?
A: The NTC-100 uses a serial connection through a 10-pin NanoFit connector utilising a pin from this to provide
power. It is not suitable for an Ethernet connection.
Note – Please refer to the RJ45 port pin out diagram in the Technical Data chapter for more information.
Q: Why can’t I configure customized AT commands from the USB AT interface?
A: The USB AT interface talks directly to the module and has access only to module AT commands. Customized
Application AT commands can be accessed only via the serial port.
