Warning: Forbid to install SIM/UIM card when powered!
Installation of antenna:
Screw the SMA male pin of the cellular antenna to the female SMA interface of the IP MODEM
with sign “ANT”.
Screw the SMA male pin of the GPS antenna to the female SMA interface of the IP MODEM
with sign “GPS”.
Warning: The cellular antenna and the GPS antenna can not be connected wrongly. And the
antennas must be screwed tightly, or the signal quality of antenna will be influenced!

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 IP Modem’s Parameters Configuration
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...”

3.3.3.2 Trigger mode
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.
