Chapter 3 Configuration
3.1 Configuration Connection
Before configuration, it’s necessary to connect the IP MODEM with the configure
PC by the shipped RS232 or RS232-485 conversion cable as following.
3.2 Configuration Introduction
There are two ways to configure the IP MODEM:
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 IP MODEM enter configure state. The steps how to
make IP MODEM enter configure state, please refer to appendix.
The following describes how to configure IP MODEM with the configure software
tool. At the same time, it gives out the corresponding AT command of each
configuration item.
3.3 Run the configure Tool: IP Modem Configure.exe
The “Serial Parameters” column shows the current serial port settings. To configure
IP MODEM, please choose the correct serial port which connects to IP MODEM, 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 IP MODEM,
Waiting IP MODEM Enter Configure State...”
3.4 Re-power IP MODEM
After Re-power IP MODEM, The configure tool will make it enter configure state.
At the same time, the software will load current settings from IP MODEM and
displays on the right configure columns. It’s now ready to configure.

3.5 Configuration
3.5.1 Data Service Center Settings
Settings on this page are the parameters related to Data Service Center(DSC).
◆Data Center Number
IP MODEM support two Data Service Center methods to transmit data.
Main and Backup: IP MODEM 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: IP MODEM 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, IP MODEM work in Main and Backup DSC
method.
When “Data Center Number” is greater than 1, IP MODEM 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:
IP Address 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
Backup Center DNS Server is used to resolve the Main center and Backup center
correspondingly.
AT command of Main Center DNS server:
AT+DNSSVR=aaa.bbb.ccc.ddd
aaa.bbb.ccc.ddd: The DNS server IP address(must be IP address）.
AT command of Backup Center DNS server:
AT+DNSSV2=aaa.bbb.ccc.ddd

◆Center 2~5 DNS Server
When the IP MODEM work in Multi Data Service Center method and the centers
use domain name, 2~5 DNS server is used to resolve center 2~5 correspondingly.
AT command of 2~5 DNS Server
AT+DNSSVRn=aaa.bbb.ccc.ddd
n is 1~4 correspond to center 2~5 DNS server.
aaa.bbb.ccc.ddd is the DNS server IP address
3.5.2 IP MODEM Settings

◆Trigger Type
Normally, IP MODEM always keeps online and always be ready for data
transmission. But in some circumstances, it’s important to reduce wireless data flow.
To realize this function, the software can makes IP MODEM into sleep state in idle
time. When there is application data to transmit, IP MODEM can be triggered online
ready for data transmission. There are total five methods to make IP MODEM online:
AUTO: IP MODEM always keeps online
SMSD: send a special short message to make IP MODEM online
CTRL: make IP MODEM online through a phone call to IP MODEM
DATA: send special serial data to make IP MODEM online
MIXD: the combination of SMSD, CTRL, DATA. IP MODEM will be online when
meet one of these three trigger methods.
AT Command:
AT+ACTI=xxxx

1 --- simple prompt information output
2 --- detail debug information output
AT Command:
AT+DEBUG=x
x : the debug level value
Note: Only there is some problem to the IP MODEM, It’s necessary to set this
value as 2, In normal applications, this value should set to 0 or 1, the
default value is 1.
