1 Introduction
The IP SERIAL SERVER provides a serial device server for Windows hosts to control RS232/RS422/RS485 devices
located virtually anywhere through a TCP/IP or UDP/IP Ethernet connection. The IP SERIAL SERVER has one
asynchronous serial port connection on one side, and a 10/100 Mbps Ethernet connection on the other side. It connects
devices, such as CNC, weight scales, and scanners. Applications include industrial/factory automation, automatic
warehouse control, and hospital/laboratory automation.
The IP SERIAL SERVER Windows driver is designed to control the IP SERIAL SERVER Ethernet devices. The driver
installs a virtual COM on windows which maps the virtual COM port to the IP address of the IP SERIAL SERVER device
across the network, enabling the Windows applications to access remote serial devices over Ethernet.
IP SERIAL SERVER can function as a server or client for both TCP and UDP connection. The application scenarios are
direct IP mode, virtual COM mode, and paired mode. In direct IP and virtual COM modes, IP SERIAL SERVER should
only work as a server. When in the paired mode one IP SERIAL SERVER must set as a client and the other must set as a
server in both TCP and UDP connection. IP SERIAL SERVER also provides a heartbeat connection for application or
virtual COM to detect whether IP SERIAL SERVER is still online.
1.1 Direct IP mode
In direct IP connection, applications can communicate with IP SERIAL SERVER using TCP/IP or UDP/IP socket
connection. The raw data in the IP packet will be transferred from and to IP SERIAL SERVER’ serial port.
1.2 Virtual COM mode
In the virtual COM mode, the host connects to IP SERIAL SERVER through 10/100 Ethernet. The serial device is then
connected to IP SERIAL SERVER.

Applications work just as if the serial device is connected to host’s COM port, however it is a virtual COM port that
convert application’s data into IP packet. IP SERIAL SERVER then converts the IP packet back to serial data. In this mode,
IP SERIAL SERVER must set to either TCP/server or UDP/server. The virtual COM driver is a TCP or UDP client. A
security feature is built in IP SERIAL SERVER. When IP SERIAL SERVER works as a server it will allow incoming
connection only when remote IP address passes its IP address filtering. For more detail, please look at the section,
Configuring IP SERIAL SERVER.
1.3 Paired mode
Paired mode is also called serial tunneling. Two IP SERIAL SERVER are involved and they must be set to a client and
server pair. The remote IP address of the client site must be the same as server’s IP address and IP address of the client site
must pass server’s address filtering. Applications do not actually use virtual COM port. They use the regular COM port and
host connects to IP SERIAL SERVER through a null modem cable as shown below.

The paired mode is a quick method to convert a serial connection into an Internet connection without installing any other
software on the host.
1.4 Heart beat
IP SERIAL SERVER provides a convenient way to reconnect TCP data connection, in case of power failure on either
client or server site. TCP port, 5300, is reserved for the heartbeat connection. After a client, either virtual COM or IP
SERIAL SERVER, establishes a data connection to an IP SERIAL SERVER server, it will start the heartbeat connection.
When the heartbeat connection is established. The server will send a signal to the client every 5 second. The client would
timeout after 5 second if it did not receive the signal and it will try to reconnect the TCP data connection every 5 seconds
until the server is back online. Heart beat only works for the TCP connection, not for UDP connection. When an application
works on direct IP connection mode. It can choose to work either with or without heartbeat connection.
