2 Serial Port Configuration
Before making this device configuration, make sure that the necessary software is installed on your computer
and that the network is properly configured.
The minimum configuration requirements for a user's computer are as follows:
◆Installing the operating system (such as Windows XP/2000, etc.)
◆Installing Ethernet Card
◆Installing Web browsers (IE6.0 and above)
◆Install and start the TCP/IP protocol
2.1 Network Visit
Device Default IP address is: 192.168.1.253, subnet mask: 255.255.255.0. When accessing devices through
the Web, the IP of the device and computer must be in the same local domain network. You can access the Web
configuration interface for a device using a standard Web browser such as Internet Explorer (ie browser).Before
you access the device through a Web browser, the device's Ethernet port is connected to your LAN or directly to
your PC network.
Step 1: pen IE browser on PC.
Step 2: Enter the IP address in the address bar of the IE browser, such as "192.168.1.199", press the
"enter" key.
Step 3: Enter the username and password in the pop-up dialog box. (username admin, password 123)
Click OK to enter the device Web configuration interface.

MAC ADDRESS
The hardware address of the device is made up of 48 specialist (6 bytes),16 binary digits, its uniqueness (not
recommended customers to independently modify).
IP ADDRESS
IP address is assigned to the connection in the Internet addresses of the devices on a 32-bit length. IP address
is made up of two fields: the network number field (net-ID) and host number field (host-ID). IP addresses by the
Defense data network network information center (NIC) for distribution. In order to facilitate the management of
IP addresses and IP addresses are divided into five categories. As shown below:
Network Type Address Range Available IP Network Range
A 0.0.0.0～126.255.255.255 1.0.0.0～126.0.0.0
B 128.0.0.0～191.255.255.255 128.0.0.0～191.254.0.0
C 192.0.0.0～223.255.255.255 192.0.0.～223.255.254.0
D 224.0.0.0～239.255.255.255 None
E 240.0.0.0～246.255.255.255 None
Other Address 255.255.255.255 255.255.255.255
Where a, b, and c addresses are unicast (unicast) address of class d addresses for multicast (multicast)
address; Class e addresses are reserved for future special uses. Currently used in the IP address belongs to a, b,
and c addresses.
IP address in dotted decimal way. Each IP address is represented as 4 decimal integers separated by decimal
points, one for each integer bytes, such as 10.110.50.101.
This series devices only support a static IP address, manually set the specified IP address and gateway. Through
the IP address can be set by accessing the device's configuration page. Set a new IP address required to log in
again.
Step 1: In the navigation on the left side, select "system settings."
Step 2: Modify a device's IP address and gateway, the equipment and access device hosts on the same local area
network.
Step 3: Click "settings" to set the IP address to take effect and prompted to log into the Web interface again.
-----End
User Password
This series devices provide only a user name password to modify. This function allows you to modify the
password for the current user name.
Step 1: In the navigation on the left side, select "system settings."
Step 2: Sets the password for the new user name.
Description:User name cannot be changed (default: admin).
Step 3:Click "settings", set the user name replaced the current user name, need to log in again.

Description
Serial Port
1~4
Select the serial number you want to set.
Baud Rate
110,300,1200,
2400,4800,9600,19200,
38400,57600,115200
default:9600
Set the baud rate for this serial port. The baud rate represents the
format of the data bits transmitted per second, a parameter that
measures the speed of the communication.
Data Bits
5~8
Default:8
Sets the data bits for this serial port. Data bits refer to the number of
bits of actual data in each byte, which is the parameter to measure the
actual data bits in the communication.
Stop Bits
1,2
Default:1
Sets the stop bit for this serial port. The stop bit is used to identify the
end of a packet data. The stop bit is not only used for packet
transmission end flags, but also provides the opportunity for
correcting synchronous clocks between computers. The more bits that
are used to stop bits, the greater the degree of tolerance for
synchronization of different clocks. However, because the stop bits
occupy the data space, excessive stop bits will result in a decrease in
data transmission speed.
Parity
even, none, odd.
Default: none
Sets the parity bit for this serial port. Parity is used to determine
whether the received data bits are wrong. For even and odd parity, the
serial port sets the parity bit, and a value ensures that the transmitted
data has an occasional or odd logical high. For 1 and 0 checksums, it
does not really check data, simple value bits logic high or low logic,
so that the receiver can know a bit state, determine whether there is
noise interference or transmit and receive data is not synchronized.
Even: Odd checksum, if the checksum is set to "odd", the number of
1 in the sending data is odd, the check digit is "0"; the parity bit is "1"
when the number of 1 in the sending data is even. None: No
checksum, when data is sent, if the check digit is set to "none", no
check digit is sent, or a checksum is sent. Odd: Parity, if the
checksum is set to "odd", the number of sending data is odd, 1, the
check digit is "1"; the parity bit is "0" when the number of 1 in the
sending data is even.

2.3.1 TCP Server Mode
Configuring the TCP server mode parameter is shown in the following illustration:
When a device is a TCP server, only the local port number is configured (For multiple serial devices different
serial ports need to set a different local port number)
【Local Port】
The device as TCP server provides a TCP port software parameter configuration diagram that is connected to
other TCP/IP nodes, as follows: (PC Active to connect device so protocol selects TCP Client, IP for device
IP192.168.1.253, port number for device local port

2.3.2 TCP Client Mode
Configure the TCP client mode parameters as shown in the following illustration:
As a TCP client side, the device proactively connects to TCP/IP network devices on Ethernet, such as PCs.
You need to tell the device which network address and TCP port number to connect when the condition meets.
When the socket is established, the device will send the data received from the corresponding serial port through
the socket, conversely, the data received from the socket will be sent to the corresponding serial port.
For TCP client settings options: Remote port, IP address configuration options are interpreted as follows:
【Remote Port】
The TCP port number to which the device connects. (For multiple serial devices different serial ports need to
set a different remote port number)
【IP Address】
The IP address or domain name address that the device connects to, both of which correspond to the host
address on the Internet.
The software parameter configuration diagram is as follows: (The device actively connects the PC so the
protocol selects TCP server, IP for PC 192.168.1.110, port number for the device remote port number 30000)

2.3.3 UDP Mode
Configure UDP mode parameters as shown in the following illustration:
In UDP working mode, the device is both the server side and the client side. UDP-related configuration
options have remote port, IP address. UDP supports peer-to-peer, and configuration is similar to TCP mode.
(For multiple serial devices different serial ports need to set a different remote port number)
The software parameter configuration diagram is as follows: (protocol selects UDP, IP for PC IP
192.168.1.110, port number for device remote port number 30000)
Click Connect to appear in the next Figure red box will be normal communication.
