Chapter 3 Configuration
3.1 Configuration Connection
Before configuration, It’s necessary to connect the DTU with the configure PC by
the shipped RS232 or RS232-485 conversion cable as following.
3.2 Configuration
There are two ways to configure the DTU:
Configuration software tool: All the settings are configured through the shipped
software tool. It’s necessary to have one PC to run this tool.
Extended AT command: All the settings are configured through AT command, so
any device with serial port can configure it. Before configuration with extended AT
command, you should make DTU enter configure state. The steps how to make DTU
enter configure state, please refer to appendix.
The following describes how to configure DTU with the configure software tool. At
the same time, it gives out the corresponding AT command of each configuration item.
3.2.1 Run the configure Tool FfDtuCfgTool-En.exe
The “Serial Parameters” column shows the current serial port settings. To configure
DTU, please choose the correct serial port which connects to DTU, and the baudrate is
115200 with no parity, then open the serial port. If the button text is “Close”, it shows
the serial port now has been opened. If the text is “Open”, you should open the port
first. When the port opened, the “Output Info” column will display
“Port(COM1) Has Opened，Please Re-Power the DTU,
Waitting DTU Enter Configure State...”

3.2.2 Re-power DTU
After Re-power DTU, The configure tool will make it enter configure state. At the
same time, the software will load current settings from DTU and displays on the right
configure columns. It’s now ready to configure.
3.2.3 Start Configuration
3.2.3.1 Data Service Center Settings
Settings on this page are the parameters related to Data Service Center(DSC).
◆Data Center Number
DTU support two Data Service Center methods to transmit data.
Main and Backup: DTU always tries to connect with the Main DSC. If fails to
connect with Main DSC, it will connect with Backup DSC at once
Note：If no Backup DSC exists, please configure the Backup DSC same as Main
DSC.
Multi Data Service Center: DTU can connect with at most five DSC at the same
time.All the multi DSC can receive the same application data .
If the Data Center Number is 1, DTU work in Main and Backup DSC method.
When “Data Center Number” is greater than 1, DTU works in Multi Data Service
Center method
AT command:
AT+SVRCNT=x
x: Data Service Center number
Note: every AT command is terminated with a enter character.
◆Main Center Addr+Port:
IPAddress and Port of the Main DSC, It’s better to set the port greater than 1024.

AT command of the Main DSC IP address or domain name:
AT+IPAD=xxx
xxx: The IP address or domain name.
AT command of the Main DSC port:
AT+PORT=xxx
xxx: The port value
◆Backup Center Addr+Port:
IP address and port of the Backup DSC
AT command of the Backup DSC IP address or domain
AT+IPSEC=xxx
xxx: The IP address or domain name
AT command of the Backup DSC port
AT+PTSEC=xxx
xxx: The port value
◆Multi DSC Configuration
When “Data Center Number” is greater than 1, this setting is valid. For example，
setting the “Data Center Number” as 3, Main Center, 2nd Center, 3rd Center work as
these three DSC
AT Command of the 2~5 DSC IP address or domain name
AT+IPADn=xxx
n is 1~4 correspond to center 2~5
xxx: The IP address or domain name
AT Command of the 2~5 DSC port
AT+PORTn=xxx
n is 1~4 correspond to port of center 2~5
xxx: The port value
Example:
Set IP address of center 3 as 166.111.8.238, and port 5001, the AT command is as
following:
AT+IPAD2=166.111.8.238
AT+PORT2=5001
◆Main and Backup Center DNS Server
When the DSC Internet access uses domain name, It’s necessary to set DNS server
resolving the DSC domain name. When the Data Center Number is 1, Main and
