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

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

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

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.

Basic AT Commands

Global

ati3 – fw versions

ati4 – serial number

at^scupg="http://../file.bin" – upgrade

ate0 – echo disable

ate1 – echo enable

at^scfres – factory reset

SmartCOM or

SmartCOM

Use with SmartCOM Server

 The

server

receives

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,

100Ω input impedance), and voltage (0-10V

DC, 100MΩ input impedance) controlled or S0.

Use the jumpers inside 2N

the current and voltage modes.

 2N

SmartCOM is equipped with two relay

outputs

for

switching

appliances. Refer to the Technical Parameters

in the User Manual for the maximum switching

values.

at^scport1=? – RS232 setting options

at^scport2? – RS485 setting

at^scport2=? – RS485 setting options

at^xxx="save" – module configuration saving

at^xxx="restart" – module restart (xxx=e.g. sccfg)

at^xxx="srestart" – save to module and restart

Inputs and Outputs

(#...number in range 1 - 2)

at^screl#? – relay # status

at^screl#=0 – relay # opening

at^screl#=1 – relay # closing

at^scadc#? – analogue input # status and limits

at^scadc#=? – analogue input # parameters

at^scdin#? – digital input # status and limits

at^scdin#=? – digital input # parameters

4) at^scport1=" baudrate",57600 // RS232 baudrate
