3 Networking mode Brief Introduction
This section focuses on describing application of the device. To introduce sorts of related
networking scenarios.
3.1 Star like Network Structure
The most basic network structures of the serial server is the star network topology. This kind of
network topology are also common in the local area network (LAN), a network topology. Its main
characteristic is through a network of each workstation nodes in the network equipment
concentration equipment (such as a hub or switch) together, are distributed in each node satellite.
This kind of network structure is more convenient in the equipment increase or decrease. The
following figure describes the Star like Networking structure：

12
In this network structure, each terminal work as an independent node to connect to the server.
The server can commune with each terminal by way of TCP or UDP. To achieve all of the serial port
terminal is connected to the Internet.
3.3 Bus Network structure
The character of Bus networking structure is that all the devices are directly connected to one
bus, which is a set of network with low cost. However, all the devices in the network share the
bandwidth of the bus, therefore, the network transmission rate will decline along with the increase in
user. RS - 485 bus structure is typical sample of this structure. The bus structure diagram is as
follows:

13
In such a network structure, all the equipment through the same cable connect to the server.
Network maintenance and extension of relatively is easier, the response speed of the equipment and
network transmission rate is less than star bus structure.
3.4 Peer-to-peer Network structure
Using the Device, original serial device can be connected to peer-to-peer network structure. The
characteristic of this structure is that all the devices in the network status are equal. For user’s
equipment, there does not exist master-slave relationship or a managed device. All user terminals can
be equivalent to send and receive data. The structure diagram is as follows:

Using the serial server, user’s serial devices can be equivalent to connected to the Ethernet.
Thus, to achieve peer-to-peer communications through Ethernet.
4 Quick start Guide
This section describes how to manage to use the device as soon as possible, users can become
familiar with the major operations quickly with the serial server, according to the introduction of this
section.
4.1 Preparatory work

The serial server and matching power supply
Ethernet cable
Direct serial line
zSoftware
Serial Debug software, such as serial port Debug assistant, serial master and so on.
TCP/UDP Debug software
4.2 Power-up Test
1. Power up the serial server. The Link light will flick at low frequency after power.
2. Connected the serial server with WIFI or network cable (or you can connect the PC and the
serial server in the same LAN through hub or router).
3. The IP address of the PC should be set to 192.168.16.X. The default IP address of the Serial

Server is 192.168.16.254
4. Make sure the PC side can ping the serial server.
4.3 Function Test
1. Power on the device, Connect the RS232 and the internet, make sure you PC can ping
192.168.16.254:
2. Start the serial Debug software，we use Serial&TCP_UDPTool.exe in this sample;
3. Start a TCP client like the below:

5 Product parameter configuration and instruction
The serial server has built-in Web Server, users can configure the parameters of the serial server
via web pages. Also, you can logo in to the website to see the current serial server parameter
settings.
5.1 Serial Server Logo in
When you have enter the web sit, you needs to change the password to avoid non-administrator
rewritten it illegally. The default user Name and password of the serial server are admin/admin.
Please rewrite the password after first use.
Note：The serial server only provide user login password setting. Please keep the rewritten
password firmly in mind.
5.2 Serial server Parameter inquiry
After passing the IE browser to log in to the serial server, you can see the screen shown below.
This page shows the main current operating parameters of serial server.
