Ethernet is system’s backbone and each serial device will be upgraded to be ONE networking node at Ethernet. Each device can access other devices directly, like a PC at networking. For example, Power industry’s RTU devices. For this networking device market, Advantech offers ADAM-4577, 1-port universal device networking server, to meet customer’s needs. ADAM-4577 not only support host PC’s polling mechanism but also devices’ peer-to-peer communication, event handling for urgent requests and modem AT-type command control. This product will be available at Jan, 2002. * * * * * * * * * * * * * * * * * * * * * * * * * * * * * 802.11b is the most widespread wireless LAN standard. It describes a wireless LAN that operates in the 2.4GHz frequency range with a data transmission speed of up to 11Mbps using spread spectrum technology. (This specification was also known as Wi-Fi, but that term now encompasses newer standards such as 802.11a and 802.11g.) The 2.4GHz range is already crowded, however, with microwave ovens, cell phones, PDAs, Bluetooth, and other devices, so signal interference is a risk. What is Ad-Hoc and Infrastructure mode? I will explain them later. * From this slide, everybody can know some spec of modules, ADAM-4571W offer One port and ADAM-4570W offers TWO port. About LED display. It is very useful, user can know the operation of WLAN packet switching from Active LED. And also know the connection Quality with AP via Quality LED * 串口设备服务器配置工具 串口设备服务器的应用 串口设备服务器应用: 工业 远程 PLC 编程/
