Based on E-Link records transmitter belonging to the practical application associated with technological innovation - e-trade - Business

Abstract: E? Iink may be a cheap, hassle-free plus tight serial Ethernet program module. With your vigorous development with Intemet, men and women can be with a variety of areas through the Internet in order to exchange information. Various intelligent equipments in addition to equipment needs that multi-level function, over the E? Link information transmission device, please take a serial dock allowing easy flip open access towards multilevel associated with existing products absolutely no more time necessary PC + minute card + apparatus interface card, special by E? IJink can simply access the particular Ethernet. Use of low-cost "E? Link system records transmission device", with the Internet for you to substitute this bus, hence the original Fieldbus sent out control procedure simply changed straight into Ethernet-based dispersed cont rol system. Keywords: Ethernet: E? Link: Serial Interface: Network: Data transmission apparatus 1 Introduction With the acceptance with Internet and the rapid development connected with professional automation. Network possesses in-depth homes, offices, factories, in addition to automation as well as control. E? Link high-speed community network control includes the particular microprocessor as well as Ethernet interface, serial machine by which the Internet might be effortless to be able to put into action directly into the particular command process to share data resources, it is joined Ethernet as well as serial equipment bridge. Ethernet Ethernet interface circuit in order to complete that physical part lOBaseT Communicate In your high-speed microprocessor C51 terms prepared to the bodily TCP / IP protocol in addition to some other (RS-232, RS-485, CAN, etc.) Conversion Agreement. Therefore, from the E? Link Internet serial devices is usually simple, will not really cont ain complex community protocols, exclusively handles E? Link pertaining to data exchange. couple of E? Link records transmitter Introduction 2.1 Features E? Link records copy device may be a micro-Internet Access Module. Can often be handed out serial apparatus or perhaps different user's bright system access Internet, with the module's interior TCP / IP network protocol along with 10Base? T circle interface to hook up to Ethernet, serial devices without difficulty realize networking. E? Link data transmitter _ along with smaller width in addition to decreased power consumption, cheap plus relieve that will use. Serial devices is often self-operating state in addition to operating parameters like TCP, or maybe UDP info to supply packets to regulate who is able to gain real-time transmission involving information. This process offers this characteristics: (1) No mileage in addition to nationwide boundaries, so long because Ethernet could communicate; (2) the particular common make use of associated with multilevel resources. No lounging connected with arena bus; (3) real-time transmission, excessive shift rate. The serial costs as long as 115.2kb / s. E? Link facts transmitter can be utilized with communication systems, manufacturing area automation systems, deposit plus insurance systems, remote control associated with sent out devices, huge retail systems, building management methods and brilliant automatic alarm in addition to Fire Linkage system. 2.2 Main technical catalog MC [I to be able to 16-bit AVR MEGA high-speed processor, crystal Oscillator The frequency can be 14.745 6 MHz, that external memory space ability with 32KB, that internal FLASH recollection capacity: 128 KB. Can present 16MI / utes regarding processing refinement power. Support agreement: ARP, IP, UDP, TCP, IC MP, DHCP as well as DNS. Network Interface: RJ45 (10BASE a T) Ethernet interface. Interface Type: RS232, RS422,. RS485, CAN bus. Serial rate: more than two hundred b / s? 115 2 hundred b / s. Maximum shift rate: 300KB / s. Product Dimensions: 8.0 emXlO. O cm or less. Power supply: AC or perhaps DC electricity supply. Software Support: Windows XP. Windows 2000. WindowsNT, Windows95/98/ME. Unix Ware SVR4-2, UnixWare 7 SVR5, SCO Open Server, SCOUNIX, Linuxfixed tty for 2.0. x, 2.2. x as well as I, inux true tty for2. O-36, 2.2. x, 2.4. x (all individuals are in the process TCP / IP Networks). Development board together with 32 Switch Volume of two-way I / O control plus 8 10-bit A / D converter. Development environment: when using the totally free AVR? GCCC dialect programming. Users don't need take into account to get expensive AVR-specific C words compiler (such when IARFORAVR, ImageCraftICCforAVR as well as CodeVisonC, etc.), plus the development from the system is FREE? WARE, might be fully based while using conditions in the program associated with cutting, higher efficiency development.
