4.1 Configuration
The basic
configuration and firmware download take place during the
2N SmartCOM
®
manufacturing process. In general, no additional configuration is necessary except for
GPRS connection to the Internet on the GSM module and the port baud rates, which
may be different depending on the providers and types of peripherals. You can
configure
in one of the following two ways.
2N SmartCOM
®
Via the RS-232 serial interface; or
Via the IP interface.
Configuration via RS 232
The RS-232 port is always in the data mode upon power up, which means that it
retransmits all captured events to GPRS port 10001. Therefore, to configure
2N
®
via the serial port, switch the port into the command mode first and then
SmartCOM
get connected to it using your PC serial port. The baud rate is 115,200 bps by default.
Now enter the following sequence of characters, preceded and followed by a 1–second
delay, into the terminal:

When
answers OK, you can start configuring the device using the AT
2N SmartCOM
®
commands listed in
.
Subs. 4.2
Restart the RS-232 port when you have finished configuring to return into the data
mode. Send the following command:
at^scport1="restart"
Configuration via IP
If you know the
public IP address, you can configure the device
2N SmartCOM
®
remotely too using the IP protocol. If not, connect to
using RS-232 as
2N SmartCOM
®
described above and send one of the following commands (for GPRS/Ethernet):
at^sccfg="local_ip" at^sceth="local_ip"
2N SmartCOM
®
will send you the IP address as negotiated with the provider or
assigned by the DHCP server in the Ethernet case. If a fixed public IP address is
activated on the SIM card, the SIM will always use this IP address. If a dynamic public
IP address is used, check the IP address whenever your restart the device.
