Description: 概述
● 全速设备接口，兼容 USB V2.0，外围元器件只需要晶体和电容。
● 可选：通过外部的低成本串行EEPROM 定义厂商 ID、产品 ID、序列号等。
● 支持5V电源电压和3.3V电源电压。
● 低成本，直接转换原串口外围设备、原并口打印机、原并口外围设备。
● 采用SOP-28封装，串口应用还提供小型的 SSOP-20 封装。
● 由于是通过USB转换的接口，所以只能做到应用层兼容，而无法绝对相同。 -Say all
● The full speed equipments connects, and permit the USB V2.0, a machine of outer circle piece needs the crystal and electric capacities only.
● Eligibility:The low cost string that passes the exterior goes the EEPROM to define factory ID, product ID, etc. sequence.
● Support the 5 V power supply electric voltage and 3.3 V power supply electric voltages.
● Low cost, direct conversion original a peripherals, original combine a printer, original combine a peripherals.
● Adopt the SOP-28s pack, an application still provides small scaled SSOP-20s to pack.
● In view of the fact convert through an USB of connect, so can make to apply the layer and permit only, but can t absolute homology.

Description: 这个小工具可以生成16进制的电力通信协议数据包，目前支持两种
协议：“中华人民共和国多功能电能表通信规约(DL/T 645—1997)”
和”山东电力集团公司用电现场服务与管理系统通讯规约”。能自
动复制生成的数据，默认为生成的数据添加0x前缀，这样就可以把
数据包方便地粘贴到代码或各种16进制调试工具里面，如“串口调
试助手”。也可以用来在调试分析时和调试状态的数据包进行对比，
以检验数据包的合法性。
本程序用
qt4.2.3 opensource + mingw
写成，最后用
molebox打包
source目录下是源代码
协议包生成工具.exe 为打包后的可执行文件，
运行时不需要额外的动态连接库
source\packet\release\packet.exe运行时需要三个dll:
mingwm10.dll
QtGui4.dll
QtCore4.d-please

Description:
RLPack is a software that gives you the power to compress your executables and dynamic link libraries in a way that keeps them small and has no effect on compressed file functionality. Further more RLPack protects your files from modification and has several protection options which help protecting your files from being changed or cracked. But compression and protection does not stop there. RLPack with iBox module can pack your dynamic link libraries and place them inside the main executable so they can not be modified. They are extracted directly to memory (or optionally to disk) hiding their presence and enabling you to keep your dynamic link libraries safe from being used by third party programs or users.-

Description: The BP7A is a complete isolated interface circuit for six and seven pack low and medium power L-Series IPMs. This circuit provides opto-coupled isolation for control signals and isolated power supplies for the
IPM’s built-in gate drive and protection circuits. The isolated interface helps to simplify prototype development
and minimize design time by allowing direct connection of the IPM to logic level control circuits.
