2.3. TCP & UDP Protocols

SE8502-M12 can be operated in two most common protocols TCP and UDP.

2.3.1. 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, SE8502-M12 offers two TCP operation Modes so users
may choose for their specific application, TCP Server Mode and TCP Client Mode.

2.3.2. User Datagram Protocol (UDP)

UDP is a faster datagram delivery protocol. User can configure SE8502-M12 to work in the UDP mode. UDP is
connectionless protocol and can transmit multicast data to/from a serial device to one/multiple h ost compu ter. 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.

2.4. Connectivity Topology

SE8502-M12 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 SE8502-M12 connection topology.

Fig 4. Typical Topology of SE8502-M12 Connection

2.4.1. 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

SE8502-M12 can be configured in the TCP server mode (PC as a client) with a unique IP and Port number, and
SE8502-M12 waits passively for the PC to establish a connection to. After the connection is established, PC can
communicate to serial devices through SE8502-M12.

Configure SE8502-M12 to be TCP server

Using one of the three configuration methods (Telnet, Web, and console), User can configure SE8502-M12 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 SE8502-M12.

Fig 6. TCP Server in Virtual COM Mode

TCP Client in Virtual COM Mode

SE8502-M12 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 Con trol Host
can exchange data with several serial devices at the same time through SE8502-M12.

Configuring SE8502-M12 to be TCP client

User can configure SE8502-M12 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 SE8502-M12, 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).

2.4.2. Tunneling Mode

Tunneling Mode is used for multiple serial devices to “talk” among one another through SE8502-M12’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 SE8502-M12 can be configured to be the TCP Server Mode with serial device connected and also another
SE8502-M12 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 SE8502-M12 tunneling mode
for Master /Slave mode PLCs or between other serial devices.

Fig 8. TCP Link in Tunneling mode

Configuring SE8502-M12 to Tunneling Mode

Using one of three configuration methods (Telnet, Web, or Console), user can configure SE8502-M12 to TCP Server

mode with a desired IP address and port, and with other SE8502-M12 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).

also true.

Fig 10. UDP Link in Tunneling mode

Configure SE8502-M12 in UDP Mode

Use one of the three configuration methods (Telnet, Web, and console). User can configure SE8502-M12 to UDP
mode. In UDP mode, SE8502-M12 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.
