2.4 Power
IP MODEM can be used in complex external environments. In order to adapt to
the complex application environment and improve the stability of the system, IP
MODEM uses advanced power technology. users can use the standard
12VDC/0.5A adapter to power the IP MODEM, or directly use the DC 9~36V
power supply to power the IP MODEM. when used with an external power, the
stability of the power supply must be ensured (the ripple is less than 300mV,
and the instantaneous voltage does not exceed 36V), and the power supply is
guaranteed to be greater than 4W.
We recommend to use the standard DC 12V/0.5A power adaptor.
2.5 Indicator Lights Introduction
The IP MODEM provides three indicator lights: “Power”, “ACT”, “Online”.

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.
Note:For the extended AT command involved in parameter configuration, please refer to "F-IM100
Extension AT Command manual"

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...”

Page 13 of 47
3.3.2 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.
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.

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.
Any phone number’s SMS can wake up IP Modem, if the trigger number is empty.
Otherwise only the trigger phone number’s SMS can trigger the IP Modem.

3.3.4 Data Service Center Settings
Settings on this page are the parameters related to Data Service Center (DSC).

Page 19 of 47
3.3.4.1 Data Service Center
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 .
Reconnect Int.(s)

Connect Retry Times
reconnect times
Back To Main Server
This item is only valid when you set “Data Center Number” as 1. In
this mode, IP MODEM will switch to backup center when main center
have problems. If this item is set to 1 , IP MODEM will check whether
the main center work fine timely. When it detects the main server
work fine, it will return back to the main server at once.
If the Data Center Number is 0,there is no DSC working.
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. The back center is invalid. The IP Modem will connect to
mulit Data Center and transmit data.

Page 20 of 47
3.3.4.2 Multi-Center Connection Check
This item is valid only when the “Data Center Number” is greater than 1.
When one of the configured data center lost connection, IP MODEM will try to
reconnect after the configured reconnect interval
Reconnect Int.(s)
reconnect time interval in second
Connect Retry Times
reconnect times
3.3.4.3 ICMP Link Check
ICMP link check send to server a icmp packet and wait reply to check the link
status. If the reply is lost, it means that the link may be broken.
ICMP Check
Enable or Disable
Dest Address
The destination address of ICMP packet to send
Check Interval(s)
The interval should not be too small. 60 is recommended(in second)
Check Times
>= 3 times
3.3.5 Serial port
IP MODEM support three individual serial ports, Port1, Port2 and RS485. All
the three ports can enter configuration state. The default parameters of the port
with baudrate 115200, data property 8N1
