1. Introduction
1.1. Overview
SW5002 Wireless Serial Server is a gateway between wireless LAN or Ethernet (TCP/IP) and
RS-232/RS-485 communications. It allows almost any serial devices to be connected to a new or
existing wireless network. The information transmitted by Serial Server is transparent to both host
computers (IP network over wireless LAN or Ethernet) and devices (RS-232/RS-485). Data from the
wireless LAN or Ethernet (TCP/IP) is transmitted to the designated RS-232/RS-485 port and data from
RS-232/RS-485 port is transmitted to the Wireless or Ethernet (TCP/IP) transparently.
In the computer integration manufacturing or industrial automation area, Wireless Serial Server is used
for field devices to direct connect to network. Terminal Server (main control program run in SW5002)
transforms whatever data received from RS-232/RS-485 to TCP/UDP port then connects devices to
the IP network via a single application program or multiple application programs.
Many control devices provide the ability to communicate with hosts through RS-232/RS-485 however
RS-232/RS-485 serial communication has its limitations. For instance, it is hard to transfer data
through a long distance. With SW5002, it is possible to communicate with a remote device in the
Intranet environment or even in the Internet and thus, increases the communication distance
dramatically.
Flexible configuration options enable this unit to be setup remotely over IP network by Telnet, web
browser, or Window utility. Packed in a rugged DIN Rail mountable case and 9~48V DC power input
range, SW5002 is ideal for almost any industrial and manufacturing automation.

4. Application Connectivity
SW5002 provides Tunneling and Virtual COM operation mode. The SW5002 is designed to transmit
data between one-or-more serial devices to/from one-or-more TCP/IP devices through wireless or
wire Ethernet, so SW5002 can enhance the accessibility of the serial device through the ubiquitous
TCP/IP based Ethernet. The connection distance limit is overcome by SW5002. Examples of these
devices are PLC controllers, card readers, display signs, security controls, CNC controller, etc.
4.1. TCP & UDP Protocols
SW5002 can be operated in two most common protocols TCP and UDP.
4.1.1. Transmission Control Protocol (TCP)
TCP provides a connection and a byte oriented data stream with control parameters such as flow
control, multiple ports option, and order delivery notification. Once the connection is established, data
can be transmitted in both directions. TCP guarantees data is transmitted from one node to the other
node(s) in orderly. The protocol also distinguishes the transmitted data for different applications (such
as a Web server or an Email server) on the same computer.
For redundant or dual-network connectivity purposes, SW5002 offers two TCP operation Modes so
users may choose for their specific application, TCP Server Mode and TCP Client Mode.
4.1.2. User Datagram Protocol (UDP)
UDP is a faster datagram delivery protocol. User can configure SW5002 to work in the UDP mode.
UDP is connectionless protocol and can transmit multicast data to/from a serial device to
one/multiple host computer. Because UDP is the connectionless protocol, UDP does not guarantee
the reliability and orderly data streams like TCP protocol. Datagram may arrive out of order or lose
without notice. But the advantage of UDP is the speed. UDP is faster and hence more attractive in
time-sensitive applications.
4.2. Connectivity Topology
SW5002 is also equipped with Tunneling and Virtual COM operation modes. It is designed to
transmit data to/from multiple serial devices and from/to multiple TCP/IP devices on Ethernet, so it
can enhance the accessibility of the serial devices immensely. Fig 4. is the example of SW5002
connection topology.

4.2.1. Virtual COM Mode
The Virtual COM software emulates a serial port with Internet or LAN topology. In the Virtual COM
Mode, COM port data (RS232) is encapsulated to Ethernet data format. By creating a virtual COM
port on a PC, the Virtual COM driver redirects communications from the virtual COM port to the
destination IP address (and the designated port number) by encapsulated COM data into IP data.
Fig 5. illustrates a Virtual COM connection diagram.
Fig 5. TCP Connection in Virtual COM Mode
TCP Server in Virtual COM Mode
SW5002 can be configured in the TCP server mode (PC as a client) with a unique IP and Port number,
and SW5002 waits passively for the PC to establish a connection to. After the connection is
established, PC can communicate to serial devices through SW5002.
Configure SW5002 to be TCP server
Using one of the three configuration methods (Telnet, Web, and console), User can configure SW5002
to be as TCP Server as following.
 Disabled the IP filter (default)
 Set the port number (default port is 4660 for COM1, 4661 for COM2).
 If IP filter is enabled, only the assigned source IP is allowed to be connected to SW5002.

TCP Client in Virtual COM Mode
SW5002 can be configured to be TCP Client mode (PC as a server) to establish a TCP connection to
an application server on PC, or the Remote Control Host. Once the connection is established, PC or
Remote Control Host can exchange data with several serial devices at the same time through
SW5002.
Configuring SW5002 to be TCP client
User can configure SW5002 to be as TCP Client for example, from Fig. 7. PC, as a server, has IP
address 10.0.0.100 and listening on port 1000. Each SW5002, connected with serial device,
configured as TCP client mode with destination IP address 10.0.0.100 and the destination port
1000, and the IP filter is disabled (by default).
Fig 7. TCP Client in Virtual COM Mode
4.2.2. Tunneling Mode
Tunneling Mode is used for multiple serial devices to “talk” among one another through SW5002’s
through wireless LAN or wired Ethernet. This mode is particularly useful when two or more serial
devices are far away. This mode can be used to extend the normal serial communication distance of
15 m to 100 m or longer.
One SW5002 can be configured to be the TCP Server Mode with serial device connected and also
another SW5002 is configured as TCP client with serial device connected. After the connection is
established, both serial devices can exchange data to each other transparently. For example,
User can implement SW5002 tunneling mode for Master /Slave mode PLCs or between other serial
devices.

Configuring SW5002 to Tunneling Mode
Using one of three configuration methods (Telnet, Web, or Console), user can configure SW5002 to TCP
Server mode with a desired IP address and port, and with other SW5002 is configured as TCP Clients
mode with Server IP and port as destination IP and port respectively.
 Note: TCP client has to assign the destination IP and the destination port corresponding to TCP
server’s IP and listening port (example: TCP 4660 port).
Fig 9. TCP Tunneling Mode
UDP
In UDP mode, User may exchange Multicast data from one SW5002 with multiple SW5002s, Vice
versa is also true.
Fig 10. UDP Link in Tunneling mode
Configure SW5002 in UDP Mode
Use one of the three configuration methods (Telnet, Web, and console). User can configure SW5002
to UDP mode. In UDP mode, SW5002 can be configured to communicate to more than one node
(Multicasting). Note that the Multicast IP address is limited by the Class of IP address and subnet
mask. As an example, for a network of Class C of subnet 192.168.1.X and a subnet mask of
255.255.255.0, the maximum Multicast IP address to be configured is four destinations IP’s.
