Description: 使用LabVIEW开发平台编制的程序称为虚拟仪器程序，简称为VI。LabVIEW（Laboratory Virtual instrument Engineering Workbench）是一种图形化的编程语言，它广泛地被工业界、学术界和研究实验室所接受，视为一个标准的数据采集和仪器控制软件。LabVIEW集成了与满足GPIB、VXI、RS-232和RS-485协议的硬件及数据采集卡通讯的全部功能。它还内置了便于应用TCP/IP、ActiveX等软件标准的库函数。这是一个功能强大且灵活的软件。-Using the LabVIEW development platform known as the virtual instrument programmed process, referred to as VI. LabVIEW (Laboratory Virtual instrument Engineering Workbench) is a graphical programming language, it is widely used by industry, academia and research laboratories accepted as a standard data acquisition and instrument control software. LabVIEW integration and satisfaction with GPIB, VXI, RS-232 and RS-485 protocol communications hardware and data acquisition card full functionality. It also has built easy to use TCP/IP, ActiveX software such as standard library functions. This is a powerful and flexible software.

Description: RS485协议，在工业控制等环境中，常会有电气噪声干扰传输线路，使用RS-232 通讯时经常
因外界的电气干扰而导致信号传输错误；另外，RS-232 通讯的最大传输距离在不增加缓冲
器的情况下只可以达到15 米。为了解决上述问题，RS-485/422 通讯方式就应运而生了。-RS485 protocol, in the industrial control environment, often have a transmission line of electrical noise interference, the use of RS-232 communication often

Description: C2Prog可以用来单片机闪存编程的工具，主要目的是简化曲C28开发代码，允许应用程序的快速下载C28无多级仿真程序的需要。
c2prog强大的特征是它的核心功能是通过动态链接库（DLL）出口由其他应用程序使用，如行结束（EOL）试验站或现场支持工具。随着c2prog DLL，Flash编程的能力可以很容易地添加到自定义应用程序的任何工具生成的，包括NI LabVIEW。-C2Prog is an industrial grade flash programming tool for TI C2000™ MCUs. Rather than solely relying on JTAG as the communication interface between the programming tool and the MCU, C2Prog also supports RS-232, RS-485, TCP/IP, USB and CAN (Controller Area Network). The programmer is, therefore, well suited for deployment in the field where the JTAG port is typically not accessible.
