  • Page 18: Hardware Installation

    Hardware installation Connecting the antenna Connect the antenna to the SMA connector on the NTC-100 serial modem by placing it on the SMA connector and turning it in a clockwise direction. Inserting the SIM card Warning – Ensure that the NTC-100 is not connected to the power cable before proceeding.
  • Page 19 Push the SIM card in until it locks in place. To remove the SIM card, push it in again and it will unlock. Figure 6 - Inserting a SIM card into the NTC-100 SIM card slot To remove the SIM card, push it in again and it will unlock.

  • Page 20: Connecting The Data/Power Cables

    Connect the Serial plug to a Serial port on your device (e.g. computer) and then connect a 5-36V power source to the DC Jack to power the unit. After powering up, the NTC-100 serial modem is ready to establish a serial communication link. To do this you must first confirm the Coms Port number.

  • Page 21: Connect To Pc Via Serial Port (Terminal Emulator)

    If the PC has the Linux operating system, you can use its command terminal to connect the serial port. Connect the NTC-100 to the PC’s serial port using the Y cable and then connect a 5-36V power source to the DC Jack to power the NTC-100 unit.

  • Page 22: Connect Via Usb Cable

    Limited AT command utility Note that the NTC-100’s ability to process AT commands via the USB connection is very limited. From the USB port you can access only Quechtel module AT commands (see Quectel AT command list on page 69 for a small selection of these types of commands).

  • Page 23: Powering The Ntc-100 Via 5V Micro Usb Socket

    Make sure any open connection on the Serial port is disabled before connecting via the mini-USB cable. Connect a standard USB Type A to USB Micro Type B cable (not included) between the NTC-100 serial modem and a powered USB port on your device (e.g. computer).
  • Page 24 Connect a standard USB Type A to USB Micro Type B cable (not included) between the NTC-100 serial modem and a powered USB port on your device (e.g. computer). Install the correct USB driver and check the AT Port number (see previous section for detailed instructions).

  • Page 25: Device Management

    SMS enabled device Serial Port (Terminal emulator) LwM2M remote server SMS commands can be sent from a mobile phones to the device’s SIM number in order to manage the NTC-100. Types of SMS commands The NTC-100 employs three types of SMS commands:...

  • Page 26: Lwm2M

    The Lightweight M2M (LwM2M) feature allows you to read, write and save most of the AT command configurations LwM2M of the NTC-100 from a remote LwM2M server. Please refer to the section on page 87 for more details. Note – For local firmware upgrade and advanced QXDM log, USB port has to be used.

  • Page 28: Device Operation Mode

    In this mode, the NTC-100 acts as a Serial-IP gateway. The downstream device’s asynchronous serial data from the serial interface is converted by the NTC-100 to IP packets before they are sent across the cellular IP network to the remote destination and vice-versa.
  • Page 29 The NTC-100 default PAD mode is with PAD=0. Example PAD implementation Below is an example in which the NTC-100 is configured as a TCP server to provide an internet connection between a utility meter and remote client software. After this configuration, the remote client software can read and write to the downstream device via the serial connection to the NTC-100.

  • Page 31: Ppp Mode

    A PPP connection can be established between the DTE and the NTC-100. In PPP mode the NTC-100 acts as a PPP server and the downstream device connected via serial should have a PPP client feature. The NTC-100 accepts PPP dial in from the downstream device and the downstream device receives an IP address from the network.

  • Page 32: Read Current Device Status

    You can retrieve simple status information about the device, including the IMEI, device up time, connection up time, RSSI, RSRP (signal strength), IPv4 address and APN of the NTC-100. This command can be used to check that SIM is functioning correctly, device is registered to the network and that an IP address is received.

  • Page 33: Sms Command List

    Note that this setting is enabled by default. SMS commands can be sent from the mobile phones to the device SIM number in order to manage the NTC-100. When “set” and “execute” SMS commands are received, the NTC-100 sends an acknowledgment reply message when the command has been implemented.

  • Page 87: Lwm2M

    The Lightweight M2M (LwM2M) feature allows you to read, write and save most of the AT command configurations of the NTC-100 from a remote LwM2M server. You can remotely reboot, factory reset and install application firmware using the LwM2M server. When the parameters are written they should be saved (Execute Save Resource /33041/0/52) before rebooting the device so that the configuration changes are retained.
