3.FUNCTIONAL DESCRIPTION
The HF9624 has the following feature
⚫Connect customer’s device with PC or server via TCP/UDP/Telnet.
⚫Contain a HTTP web server allow user to configure through browser with PC or phone.
⚫Config device remotely with IOTBridge
3.1. Basic Network Protocol
The HF9624 device uses the IP address for network communications. If uses the TCP to assure that
no data is lost or duplicated. If use UDP to assure that data can be fast and effective to Destination
address.
Supported protocols include:
⚫ARP, UDP, TCP, ICMP, DHCP, Telnet, DHCP, HTTP Server/Client Web socket
⚫Telnet command configuration, Web server configuration
⚫Security Protocol: TLS, AES, DES3 encryption

3.2. Wireless Network
Wi-Fi supported product works under AP mode as default.
AP: Wireless access point which is the central joint. Usually, wireless router is a AP, other STA
devices can connect with AP to join the network.
STA: Wireless station which is terminal of a wireless network. Such as laptop and pad etc.
3.2.1. AP Network
HF9624 4G PLC Remote Control Serial Server User Manual
http://www.iotworkshop.com - 15 -
HF9624 can construct a wireless network as AP. All the STA devices will consider the AP as the
centre of the wireless network. The mutual communication can be transponded by AP. If 4G network
connects well, PLC device will send data to public server shown as follow:
Figure 9. General AP Network
3.2.2. IOTService Software
Open the IOTService after connect to the AP hotspot generated by HF9624 or connect to Product
Ethernet port to PC, then configure the parameter.

3.2.6. Webpage Configuration
Use PC to connect with HF9624 through its AP hotspot or Ethernet connection. Input the default
IP(10.10.100.254, default username and password: admin/admin) to login the webpage to configure
the parameter.

3.3. Ethernet Interface Function
HF9624 provides with two Ethernet interface(1 LAN and 1 LAN/WAN switchable). By Ethernet
interface, user device can easily connect to the public network.

Figure 14. Ethernet Interface Function
HF9624 generates a central network. Each devices’IP address is working under the same segment
with HF9624(default as 10.10.100.XXX, can be modified). Devices can communicate mutually, and
the devices above can visit public resource normally. Device is equivalent to Wi-Fi/Ethernet/Serial 4G
Router.
