How to configure ETH port of 2N® SmartCom PRO ETH version
1. In the very first step you should read the manual, which you can find on 2N Telecommunications website
2. Connect 2N® SmartCom PRO ETH version (next just SmC+ETH) via RS232 cable and open 2N SmartCom configuration tool. In case you are using RS232/USB converter you need to use appropriate virtual COM port on your PC. The correct number of this virtual COM port can be found in "Device manager" in your operating system. Default communication Speed is set to 115200bd/s. Once you change speed of RS232, then you will need to "Load configuration" with that speed, see (Pic. 1). Keep in mind all parameters, in enclosed pictures there are only examples.
5. Once you know SmC+ETH unit IP address, you can do any reconfiguration remotely via telnet client. Putty client is used in this example. To reach the configuration mode of the unit set IP address and port 10000, see (Pic. 5).
6. AT command at^sceth? enables you to display current setting and at^sceth=? will show you all the options you can use as you can see on (Pic. 6). On (Pic. 7) you have whole list of supported AT commands which are listed in the manual, section 9.2.
