SERIAL OVER LAN



TC-CSEM53/232 และ TC-CSEM53/485 เป็นอุปกรณ์ที่ใช้สำหรับการแปลงข้อมูลเชื่อมต่อ ระหว่าง PROTOCOL ของ TCP/IP และ RS232 PORT โดยด้านหนึ่งจะต่อเข้ากับ PORT RS232/RS485 ของเครื่องจักร หรืออุปกรณ์ควบคุมต่างๆ ส่วนอีกด้านหนึ่งจะสื่อสารผ่านทาง LAN แบบ ETHERNET ด้วย TCP/IP PROTOCOL โดย TC-LZ จะทำหน้าที่เป็น DATA PROTOCOL CONVERTER ลดความยุ่งยากสำหรับผู้ใช้งาน และลดการทำงานของบอร์ดควบคุมต่างๆ ที่จะนำมาเชื่อมต่อระบบ ส่งผ่านข้อมูลทาง LAN สามารถนำไปใช้ประยุกต์งานต่างๆ ได้มากมาย เช่น ต่อเป็น NETWORK ผ่านทางระบบ LAN และใช้เพื่อทดแทนคอมพิวเตอร์ที่ไม่มี Serial port และที่สำคัญคือเพื่อความสะดวกในการเดินสายสัญญาณ

Products require 3.3 volts DC of regulated power for normal operation.Module type is a relatively compact unit in a larger device or arrangement that is designed to be separately installed, replaced, or serviced. Typical characteristics of modular components include portability, which allows them to be used in a variety of systems, and interoperability, which allows them to function with the components of other systems.Ethernet is the most widely-installed local area network ( LAN) technology. Specified in a standard, IEEE 802.3. An Ethernet LAN typically uses coaxial cable or special grades of twisted pair wires. Devices are connected to the cable and compete for access using a Carrier Sense Multiple Access with Collision Detection (CSMA/CD ) protocol.Supports 3.3V Transistor-Transistor Logic(TTL) Level. Short for TTL, a common type of digital circuit in which the output is derived from two transistors. Many TTL logic gates are typically fabricated onto a single integrated circuit (IC).Supports Firmware upgrades over TFTP software which is hotflash.exe. TFTP is short for Trivial File Transfer Protocol, that is an Internet software utility for transferring files that is simpler to use than the File Transfer Protocol (FTP) but less capable.Supports telnet.You can configure and go over products through telnet.Supports DNS function. DNS is short for Domain Name System (or Service or Server), an Internet service that translates domain names into IP addresses. Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address. For example, the domain name www.example.com might translate to 198.105.232.4. The DNS system is, in fact, its own network. If one DNS server doesn't know how to translate a particular domain name, it asks another one, and so on, until the correct IP address is returned.Supports DDNS function. DDNS is short for dynamic Domain Name System, a method of keeping a domain name linked to a changing IP address as not all computers use static IP addresses. Typically, when a user connects to the Internet, the user's ISP assigns an unused IP address from a pool of IP addresses, and this address is used only for the duration of that specific connection. This method of dynamically assigning addresses extends the usable pool of available IP addresses. A dynamic DNS service provider uses a special program that runs on the user's computer, contacting the DNS service each time the IP address provided by the ISP changes and subsequently updating the DNS database to reflect the change in IP address. In this way, even though a domain name's IP address will change often, other users do not have to know the changed IP address in order to connect with the other computer.Supports Telnet COM Port Control Protocol, specified by IETF RFC 2217. 'COM Port Control' is an extension of the Telnet Protocol. It allows redirector software to send configuration information to an Access Server. It also allows the Server to send the client redirector any serial line status changes, and allows the client redirector to manage flow control with the Access Server. When making a connection without using Telnet COM Port Control, the client redirector is still able to communicate with the server, but it will only be able to send and receive data, which is fine for use with many PC applications. However by using Telnet COM Port Control when making a connection, the client PC application is also able to read status lines and control signals on the client redirectors virtual COM port which is exchanged with the Server, allowing a wider range of PC application software to be used sucessfully.In this mode, both TCP client and TCP server can be performed without additional configuration. ezTCP tries to make tcp connection as a client. If ezTCP is not on any connection, it can allow tcp connection requests from another client as a server.This function can be used when a server needs to identifiy multiple remote devices. By using this function, ezTCP sends MAC address to the remote host right after the connection is established.

CSE-M53 is a module for manufacturers who want to quickly and easily embed Ethernet connectivity in their products. This very compact module helps your devices get network connectivity with just serial connection at a reasonable price. That is why we expact that CSE-M53 will be the best seller in the future. Applying this module, not only you can reduce cost and risk, but also you can shorten development time to add the network capability. Because CSE-M53 allows to extend the distance of your serial communication system, you are able to remotely control and monitor the serial devices over the Internet anywhere you are. Since CSE-M53's UART port can be designed to interface with RS232, RS422 or RS485 systems, it is available on various environments.
