5.3.1 Device information.
Device information included device name, device description, hardware version, software version, MAC
address as figure 5.4.
Device name
Named a different name for each device in the network, it can support Chinese characters, not more than
30 bytes. It can input capital letter and lowercase, Chinese characters, special character，underline, middle line.
Device description
Describe the device, not more than 30 bytes.
5.3.2 Network information
Device address setting supports 2 modes，DHCP and static IP address, When opening DHCP function，IP
address of the device can be obtained by software VSP manager software. If it is needed to connect Domain
Name System, please fill in available gateway and DNS address.
IP address
IP address is a 32 bits length address provided the device that connect to the Internet. IP address has 2
filed: net-id and host-id，IP address can set in static IP or DHCP.
Subnet Mask
Mask is an IP address corresponding 32 bit number, it has 1 and 0. Mask can divide IP address into 2
parts: subnet addresses and host computer addresses. 1 bit in IP address and mask correspond subnet address.
Default gateway
The default gateway in the Host computer usually called Default route. Default route is the route chosen
by the router when destination address of IP packet cannot find the existance of other routes. All packets of
destination address not in router's routing table will use the default route.
DNS address
DNS full name is Domain Name Server, the function is easy to remember the DNS. It resolves to the IP
address internet can identify. If our device need to visit some Host device, it need to use this server to resolve an
IP address.As figure 5.5。

（Figure 5.4）
：
If it need to set DHCP “automatically obtain IP address”, please ensure DHCP Server is already in the
network.and can obtain IP address successfully. After “automatically obtain IP address”, it is need to use
software VSP manager software to search the device and obtain the IP address of the device.

Enter into NP301’s Web interface, click [Serial Setting], choose the required configuration in the
corresponding drop-down menu.。Serial settings Web interface as figure 5.5。When NP301 communicate with
serial interface device, NP301’s setting is as follows:。
（Figure 5.5）
Some items related with serial settings：[Serial Mode]、[Baud Rate]、[Parity]、[Data Bits]、[Stop bits]、
[Max Data Packets Lenth] and [Character Delay] ，CtrlBreak Default Output Time. The meaning of these
configuration options are explained below,
Serial Mode：It is similiar to full and half duplex mode of Ethernet.
Baud rate: It is a parameter to check the communication speed. It shows to transfer how many bits in 1
second. For example, 300 baud rate means have 300 bits transferred in 1 second.
Parity bits: It is a simple method to checkout fault in seral communication, have 4 types:

Shenzhen 3onedata Technology Co., Ltd
13
Even, Odd, Mark, Space
Data bits: It is a parmeter to check the actual data bits in communication. When PC send a Packet, actual
data is not 8 bits, the standard is 5, 6, 7, 8.
Stop bits: The last bit of the single Packet, Typical bit is 1, 1.5 and 2. NP301’s stop bit is 1, 2.
Data frames: The frame length that serial interface data convert into Ethernet data, within the range of
setting time, it forwardes when data is equal to or longer than the setting frames. Available
setting value ranged from1 to 1024.
Character spacing: The wait time when serial interface send data do not 1 data frames. If up to this time
and do not have data, then send automatic.
CtrlBreak default output time: Setting CtrlBreak default output time.

Sessions：Each serial port of serial device servers can support 1-4 sessions. It means serial port of serial
device server send the received data to Ethernet through socket. More than one of the sessions means serial port
of serial device server sends the received data to Ethernet through more than one socket. sessions enable to use
by checking the corresponding box.
1. TCP client
As TCP Client side, serial device server will connect forwardly to TCP/IP network equipment, such as PC.
It need to setup to tell serial device server to connect which network address and TCP port number when
conditions is matched. After creating socket, serial device server will sent the data received from each serial
port through socket On the contrary, the data received from socket will be sent to the corresponding serial port.

Shenzhen 3onedata Technology Co., Ltd

TCP Client setting option: [Destination address], [Destination port], [Connection mode] And [Keep-alive]
The explanation of these setting is as follows
[Local port]
The setting has the correlation with TCP Server.
[Destination address]
The IP address or domain name address that NP301 will connect, both of them can corresponde the host
computer address on the Internet
[Destination port]
The TCP port number that NP301 will connect
[Connection mode]
Connection mode has 2 types: Immediately and Data trigger
Immediately: When NP301 have power supply, it will connect immediately, if connection cut off, it will
connect immediately.
Data trigger: Once NP301 receive the data, it will connect immediately.
[Keep-alive]
Setting the vacancy time for connection cut off automatic, if there do not have data transfer, NP301
connection will cut off. If set “0”, means do not care how much time vacancy, NP301 do not cut off
voluntary. The range is 1-65535s. Default is 300s
The figure below is the configuration interface of TCP Client Mode. Session 1 is setting to local address
available for router.”192.168.2.168” ，the “Destination Port” connected to serial port is host computer
192.168.2.168” 31000 port, Connection mode is Immediately, Keep-alive time is 300 seconds, please pay
attention to pure TCP Client、TCP Server、UDP or TCPAuto mode. Please close RealCom. Session 3 is setting to
Internet address available for router ”www.test.com” （the choice this time is DNS ）the “Destination Port”
connected to serial port is host computer ”www.test.com” 31002 port ，Connection mode is Immediately,
Keep-alive time is 300 seconds, click “Submit’, setting successful.
（Figure 5.6）
2. TCP server
TCP Server, Passive connect, one pivotal parameter is [Local port], have relationship with other setting,

need combine setting.
[Local port]
NP301 provide TCP port can be connect by other TCP/IP node, the TCP port have the relationship with the
NP301’s relevant seial interface.
The figure as follows is TCP Server setting interface, Session 1 set local port is 30000, external TCP port
connect NP301through this port. Connection keep-alive time is 300 second。Click “Submit”, setting
successful as figure 5.7.
（Figure 5.7）
3．UDP
Under the UDP work mode. NP301 is server and also client, the relavant setting is “Local port”,
“Destination address” and “Destination port”. It can support point to point and multicast UDP, setting method is
the same as TCP.
4．TCP Auto
In this Mode, serial device server can act as server or client. Before setting this Mode, please ensure related
parameters are correct when you turn on the server mode, client mode is automatically disconnected.
5．RealCom
RealCom Mode support TCP Server、UDP and TcpAuto these 3 types，Choose "open" or "close" to enable
this function under RealCom. After opening RealCom, users can make connection through Windows Hyper
Terminal. Generally RealCom need to open.
