Chapter 3 Configuration
3.1 Connection
Before configuration, It’s necessary to connect the IP MODEM with the 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 IP Modem’s Parameters Configuration
There are data settings in HEX format in the parameters,
for the HEX format, the data must be hexadecimal characters, and the number of characters
cannot be an odd number.
For example, "12AB" is in the correct format
"12A" format error, the number of characters is odd
"12G" format error, non-hexadecimal character
3.3.1 Run the Configure Tools
The “Serial” area shows the current serial port settings.
To configure IP MODEM, please choose the correct serial port which connects to IP MODEM,
and the baud-rate 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...”

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.
Note：To enter configure state for 4G device may need more time. It is about 40 seconds.
3.3.3 Work Mode
3.3.3.1 App protocol
The IP Modem can be configured many communication protocols to adapt for different
applications.
Note：The tool will show the reference parameters according to the communication protocols
setting.
