3.1 Putting in Operation

Operational state is 2N^® SmartCom PRO's main function. In this state, periodic data readouts from input circuits are made. 2N^® SmartCom PRO responds to queries from the superior data concentrator, which can be the SmartCom Server, monitors events on the RS 232 / RS 485 / M-Bus interfaces and sends the acquired data to the server via WWAN or Ethernet in the case of the PRO ETH version.

Initialisation

Insert a PIN-disabled data SIM card in 2N^® SmartCom PRO and connect the GSM/UMTS/LTE antenna and power supply as instructed in Subs. 2.3 – Mounting.

When the 2N^® SmartCom PRO power supply is connected, the LED indicator on the device top flashes three times quickly and then starts flashing in longer intervals. Refer to Subs. 3.2 for LED status details. The WWAN module starts communicating with the provider in about 20 seconds trying to log in and obtain the IP address. The LED starts shining constantly to indicate a successful login.

To identify the 2N^® SmartCom PRO IP address assigned by the mobile provider or perform the basic configuration upon power up, get connected via the serial port (RS 232). The port is in the data mode upon power up, retransmitting all data from the input to the WWAN network. Use the +++ sequence preceded and followed by a 1–second delay to switch into the configuration mode. When your 2N^® SmartCom PRO replies OK, start configuring 2N^® SmartCom PRO using the AT commands as listed below.

Restart the serial port to return to the data mode. To do so, either send the ATO command or disconnect 2N^® SmartCom PRO from the power supply.

When your 2N^® SmartCom PRO has been programmed as required, connect the device to the available serial ports RS 232 / RS 485 / M-Bus. Launch the hyper terminal and get connected to the 2N^® SmartCom PRO public IP address via port 10000, which, together with the serial port, can be used for configuring. Use port 10001 for retransmitting data to RS 232 and port 10002 for retransmitting data to RS 485 / M-Bus.

Basic Configuration by SCCFG Command

Enter the SCCFG command via the AT interface to make basic configuration of the WWAN module, access to the server and listening ports of 2N^® SmartCom PRO. If you do not have access to a PC, you can control the terminal via SMS to a certain extent. Refer to Subs. 4.2 for details.

at^sccfg="mode",1

• The command selects one of the following three 2N^® SmartCom PRO operational modes:
  
  • TCPCLIENT (1) – 2N^® SmartCom PRO connects to the selected server for interface data resending.
  • STANDALONE (3) – 2N^® SmartCom PRO works as a server to which clients get connected (transparent transmission between TCP and serial interfaces).
  • DATA_OFF – GSM/UMTS module 2N^® SmartCom PRO is not logged in to the data network but waits for an SMS.

at^sccfg="mode","tcpclient"
