2.2.2 Method 2: Using AT-commands via RS232
It is also possible to configure the Ethernet box by sending modem (AT-)commands via RS232. You can send
these commands manually via an RS232 monitor (i.e. Hyperterminal or Appload) or for a quicker setup you can
also connect an (RS232) barcode reader and scan configuration barcodes.
The following AT-commands can be send to configure the Ethernet box.
Option Command Example + barcode
Default host name AT+NAME<string 1-16>
Default IP-address AT+IP<address>
Default Gateway IP AT+GATE<address>
Default DNS server IP AT+DNS<address>
Default subnet IP mask AT+MASK<address>
Disable/enable DHCP AT+DHCP<boolean>
Baudrate AT+BAUD<baudrate>
Important notes:
§ All commands must be terminated with a carriage return <CR>
§ Make sure you send the commands at the correct baud rate (default is 115200bps)
§ The review the current settings use the following command: 'AT?'.
§ If a command is accepted the Ethernet box will respond with <CR><LF>OK<CR><LF>
§ If a command is not accepted the Ethernet box will respond with <CR><LF>ERROR<CR><LF>
