Basic Use without SmartCOM Server
Insert the SIM card that supports data with a
public IP address (fixed or dynamic) and PIN
request disable or the same PIN as requested
in the 2N®SmartCOM configuration.
Connect the antenna and then the power
supply.
Get connected via serial port (115200 baud,
8N1, no flow control) to identify the IP
address assigned to 2N®SmartCOM or
configure basic settings if necessary.
Upon power up, the port is in the data mode
and retransmits everything from the GSM
input. Use sequence +++ to switch into the
command mode.
Now you can configure 2N®SmartCOM
using the AT commands listed below.
Restart the port (at^scport1="restart") to return
to the data mode (also possible with ATO
command).
Connect the device to one of the available serial
ports (RS232 or RS485).
Start a telnet application (e.g. Putty) and get
connected to the public IP address of
2N®SmartCOM via TCP port 10000 to set
parameters as via a serial port.
Use TCP port 10001 for data retransmitting
to RS232.
Use TCP port 10002 for data retransmitting
to RS485.
Use with SmartCOM Server
The server receives registrations from
terminals providing central administration.
Refer to the User Manual for details on the 2N®
SmartCOM server settings, management and
use.
Input and Output Circuits
2N®SmartCOM is equipped with two serial
interfaces, which are electrically interconnected
with the GND reference point.
The input may be current (0-20mA, 4-20mA,
100Ωinput impedance), and voltage (0-10V
DC, 100MΩinput impedance) controlled or S0.
Use the jumpers inside 2N®SmartCOM to set
the current and voltage modes.
2N®SmartCOM is equipped with two relay
outputs for switching ON/OFF electrical
appliances. Refer to the Technical Parameters
in the User Manual for the maximum switching
values.
