1 Overview

1.1 Overview

CSE-T16 is a 16-port console server allowing devices with console ports to be embedded with networking capabilities. With CSE-T16, therefore, you can easily monitor status of console ports over the network from anywhere in the world. It also helps you save your time and energy by improving efficiency of integrated management and control of many devices in diverse applications.

This RS232 console server is an ideal solution for Remote Console Monitoring as it supports useful features such as 16 ports of RS232, a security protocol(SSL) to protect data transmission, sharing serial ports through the network(Telnet with RFC2217), etc.

1.2 Features

 16 x RS232 (RJ45, up to 115,200bps)  Security Functions (SSL 3.0 / TLS 1.0, Password)  3 Communication modes (TCP Server, TCP Client and UDP)  Support of DHCP for DSL and cable network  A variety of ways to monitor communication status (ezManager, TELNET)  Powerful management software for Windows OS (ezManager)  Firmware upgrade through Network

4.1 Normal Communication Mode

There are 3 types of connection to communicate with a remote host.

Topology

TCP Server

TCP

Passive

1:1

TCP Client

Active

1:1

UDP

N:M

Tabl-4-1 comparison of communication mode

TCP protocol requires connection process. The connection is always established as 1:1 connection. At this time, the host waiting for connection (passive connection) is called a server and the one attempting to connect (active connection) is called a client.

On the other hand, UDP communicates by block unit without connection process. As UDP does not require connection, numbers of hosts can communicate at the same time.

Page 25

CSE-T16 User Manual Ver. 1.2

http://www.ezTCP.com

4.2 TCP Server

In this mode, CSE-T16 listens to a TCP connection request from remote hosts. Once a host tries connecting to CSE-T16, it accepts a connection. After the connection is established, CSE-T16 converts the raw data from the serial port to TCP/IP data and sends it to the network and vice versa.

4.2.1 Key parameters

 Local Port

This is a server’s port number which is used in the TCP connection.

 Event Byte

With setting event bytes, you can handle the serial data of the serial buffer before a TCP connection is established.

Value

Description

CSE-T16 does not send the data received before a TCP connection is established

Otherwise

(512 or under)

CSE-T16 sends the data, which is received before a TCP connection is established, right after a connection is established. 512 or under bytes are strongly recommended.

Table 4-2 Event Byte

 Timeout

If there is no transmission data for amount of the time (in seconds) CSE-T16 actively close the connection. If this value is set to zero, the connection would not be terminated unless other side actively closes or there is an error on TCP connection.

4.3 TCP Client

In this mode, CSE-T16 sends request segments to a TCP server with information of [Peer Address] and [Peer Port]. Once a host is listening, the connection will be established. After then, CSE-T16 converts the raw data from the serial port to TCP/IP data and sends them to the network and vice versa.

4.3.1 Key parameters

 Peer Address

This part is to put an IP address or a host name of TCP server.

 Peer Port

[Peer Port] is a port number of TCP server.

 Event Byte

In TCP Client mode, this parameter has two functions. Firstly, this item can decide the point of time to send the connection request parameter.

Value

The point of time to send SYN request segment

Right after CSE-T16 boots up

Otherwise, N

(N <= 512 )

Right after CSE-T16 received N bytes from the serial port. Setting to less than 512 bytes is strongly recommended.

Table 4-5 the operation of Event Byte 1

Secondly, you can handle the serial data before a TCP connection is established with this parameter.

Value

Description

CSE-T16 does not send the data received before a TCP connection is established.

Otherwise

(512 or under)

CSE-T16 sends the data, which is received before a TCP connection is established, right after a connection is established. Setting to less than 512 bytes is strongly recommended.

Table 4-6 the operation of Event Byte 2

 Timeout

If there is no transmission data for amount of the time (in seconds) CSET16 actively close the connection. If this value is set to zero, the connection would not be terminated unless other side actively closes or there is an error on TCP connection.

As you can see, CSE-T16 has sent a request segment right after the size of the serial data has been 5 bytes. Even though they arrived before the connection, the data “123”, “45” and “67” was transmitted to the remote host because the [Event Byte] is set to 5.

4.4 UDP

UDP has no connection processes. In this mode, data is sent in block units. Therefore, data that comes through CSE-T16’s serial port is collected in block units to send it elsewhere.

4.4.1 Key parameters

 Block Size

[Block Size] is to set how many bytes of data need to in one block. If the number of byes arrives come into the serial port reaches the block size value, CSE-T16 will send them as one block to the network. The maximum value could be 1460 bytes.

 Dynamic update of Peer host

If you set the value of [Peer Address] and [Peer Port] to 0, [dynamic update of peer host] function is activated. By using this function, CSE-T16 can automatically change the host, allowing to communicate with multiple hosts without additional setting.

Table 4-9 states of each point

Although CSE-T16 received data “678” from serial port it does not immediately send this data because it has not gather enough block size of data. It keeps this data and waits for enough 5 bytes.

5.2 Status Monitoring through Shell command

5.2.1 How to connect

 Telnet login

Once the [TELNET] option is activated, users can remotely log in to CSE-T16. If a password is set, users should input the password.

After that, messages from CSE-T16 appear as shown in the figure below.

Figure 5-4 connect to CSE-T16

Figure 5-5 Input password



Default password is “sollae”

Figure 5-6 log in

 Console port

If you connect the console port of CSE-T16 and PC's serial port, you can check the serial and network status by a terminal program.



You can not use [Telnet] and [SSH] at the same time.

② Make a certification and write it using ezManager (Refer to the Figure6-2 ~ Figure6-5)



Certification for SSH is available on ezManager of v3.3D or higher.

③ Run the client program [PuTTY] that supports SSH and connect to port 22 (SSH default number). Try access and enter the ID and password. You will be able to connect as shown in the Figure 5-11 below.

You should generate a new certification when IP address changes. If user set SSL with CSE-T16,

the other device have to set the SSL.

6.2 Setting password

A password can be used for protecting CSE-T16 from TELNET login or changing environmental

parameters by unauthorized hosts. The maximum length is 8 bytes of Alphabet or number.



If user forgets the password, factory reset must be done, and then all the environmental variables will be reset.
