顶部端口(USB)接口,这个接口的调试是PL的使用
TOP PORT (USB) 调试接口说明
本接口是利用PL-2303HX的USB转RS232的接口芯片设计实现了一个TTL(5V)的RS232串口,并且利用了PL-2303HX的2个GPIO口软件模拟了一个低速的I2C总线.该接口由USB接口提供5V电压,可自带2Kbit(24C02)数据备份EEPROM (单独读写通道,不占用I2C总线地址)。并可对外提供小于250mA的5V电压。尤其适合WIN-XP以后的没有并口和串口笔记本电脑。整机成本不到¥20RMB。
-TOP PORT (USB) interface debugging of this interface is the use of PL-2303HX the USB to RS232 interface chip design to achieve a TTL (5V) of the RS232 serial port, and use of PL-2303HX the two GPIO port software simulation of a low-speed I2C bus. The interface from the USB interface to provide 5V voltage, can bring their own 2Kbit (24C02) data backup EEPROM (separate read and write access, do not occupy I2C bus address). And may provide less than 250mA of 5V voltage. WIN-XP is particularly suitable for subsequent parallel and serial no notebooks. Machine costs less than ¥ 20RMB.

MPLS 简介
从我的雇主的注意事项:切萨皮克网络解决方案改变了名称到Mentor技术。这样做的目的是阐明我们的身份为我们的合作伙伴,客户和投资者。该显示在页面的底部修改URL我以前的文章。 (是的,他们仍然在那里!)我一直在看MPLS,多协议标签交换,在过去的几个月。思科在话题了一些相当不错的slideware,但也出现了一些事情,我本来想钻到并更好地理解。我不能肯定地说,我是一路那里。但是这个月我想与大家分享一些MPLS的基础知识。这可能需要另一篇文章或两个来完成这个话题。IETF工作组信息(及相关文件草案的列表)的MPLS可以在这里找到:http://www.ietf.org/html.charters/mpls-charter.html对于MPLS的概述,另见:http://www.ietf.org/internet-drafts/draft-ietf-mpls-framework-05.txthttp://www.ietf.org/internet-drafts/draft-ietf-mpls-arch-06.txt我发现这非常可读两种。但后来,我已经看够了思科slideware,我有我的头一些基本的图片和MPLS的想法

sim 文件系统In addition, its quality of service reduces because of reliance on traditional circuit-switched network elements. At that former time, people hoped to build a based system, which could access a centralized server network, would always have access to the latest traffic information and could provide web links. What this trend is a momentous request for mobile services based on high-speed packet data transfer. Hence, a new standard, GPRS, came into being in order to fill people’s bill.-sim file system In addition, its quality of service reduces because of reliance on traditional circuit-switched network elements.
