3. HF2421 Device parameter configuration
There are three methods for the parameter configuration of Hanfeng industrial
control device
1, IOTService tool
2, WEB page
3, serial port Cli command. This method document does not introduce. If
you use to view the Cli commands in the user manual
3.1. IOTService Tool Introduction
IOTService software is used to configure module operating parameters and
remote management, view module status, upgrade, and other functions to
facilitate device testing.
The IOTService tool download URL is

3.2. WEB
Hanfeng Industrial Controls device also provides WEB web page configuration
parameters. the PC is connected to the product's AP or the network cable is directly
connected, enter the product default IP (10.10.100.254, default login user name and
password: admin/admin) in the browser. You can log in to configure the parameters
on the web page. Google, Firefox browser is recommended, browsers with 360 and
below IE8 are not supported

4. Transparent case One：WEB Configuration
Application Scenario HF2421 Device Passes Data Through 4G Network。The
following topology is shown。Device parameter setting requirements：the device is
connected as a client mode to our Hanfeng test server. Address:
nat1.iotworkshop.com, TCP port: 3006.
Step1: Plug in a SIM card that can access the Internet and connect the antenna to
the power supply. Then connect the hotspot or network cable of the PC directly to
the computer. Then you should check the IP address obtained by the PC.。
Note: The IP address obtained after the PC connects to the AP of the device is
10.10.100.xxx.
If the network cable is directly connected to the PC, there are two situations in
which the PC obtains the IP address. 1, the device wifi work mode is AP mode, the
PC got the IP address is 169.254.xxx.xxx. 2 Device wifi works In STA mode, the PC
gets the is 10.10.100.xxx
。
Step 2：Open the browser input device IP address, enter the settings page and then
check whether the device is connected to the 4G network, mainly to see if the

http://www.iotworkshop.com 7 Copyright © 2013 . All rights reserved
device has an IP address, as shown below. If the device's IP address is 0, it means
there is no network connection. Disconnect the SIM card after power off.
Note: The computer is best to open only one network card. If your computer's IP
address is 10.10.100.xxx, enter 10.10.100.254 to enter the web settings interface. If
the IP address obtained by the computer is 169.254.xxx.xxx, enter 169.254.173.207
to enter the web page setting interface. The SIM card of this device does not
support hot plugging.。
Step 3：Click on the communication settings, select the protocol type and fill in the
server address and port number and serial port number. After setting, click the
submit button.
Note: The HF2421 device has two serial ports, uart1 and uart2, which need to be set
corresponding to the serial port number on the device.。

Step 4 :After setting, restart the device as shown below.
Step 5：The PC opens the Serial SecureCRT tool, selects the corresponding port
number and baud rate, and displays the interactive window.
Step 6：Transparent transmission test.

5. Transparent test case two：IOTSerivice Tool
Configuration
The application scenario is the same as the case one.
Step 1: Insert a SIM card that can access the Internet and connect the antenna to
the power supply. Then, the PC connects the device's hotspot or network cable
directly to the PC.
Step2 :Open the IOTService tool and the device will appear as shown below.。
Step 3：Double-click the device bar to enter the device status interface and check
whether the device is connected to the 4G network. If it is connected, click the edit
button to enter the device editing interface. If the device IP address is 0, it indicates
that no 4G network is connected, power is off, and the card is inserted or removed.
Step 4: After entering the configuration interface, set the network communication
parameters. After setting, click OK, as shown in the figure below.
