| 1. | The protocol converter can change any facilities with the rs232 serial communicating ports to facilities with the function of connecting to net and extend the connecting distance of the host and the facilities
通过协议转换器不但可以使任何具有rs232串行通讯口的设备成为具备联网功能的网络外设，还可以延伸主机和设备之间的联接距离。 |
| 2. | Most boat carried facilities have the rs232 serial communicating ports . protocol converter makes the boat carried facilities with the rs232 serial communicating ports and without the ethernet connectors to connect directly to net
大多数船载设备只具有rs232串行通讯口，协议转换器可以使原本只有rs232串行通讯口而不具备以太网接口的船载设备能够直接联入到网络中，完成船载集成示范系统硬件平台设计。 |
| 3. | The protocol converter developed by the rabbit 2000 microprocessor and the dynamic c language to convert between rs232 serial communicating port protocol and tcp / ip protocol is the key part of the design of the hardware platform . the thesis presents a detailed description of the hardware and software design of the protocol converter
基于rabbit2000微处理器及dynamicc语言设计开发的用以完成rs232串行通讯口协议与tcp ip协议协议转换功能的协议转换器是该硬件平台的关键部件，本文对协议转换器的硬件及软件设计进行了详细描述。 |
| 4. | Experiment indicates that the converter realizes the data transfers function between the rs232 serial communicating port and the ethernet rj - 45 connector . it means that the converter realizes the protocol conversion . the software of the protocol converter is developed by the client / server mode
实验表明本论文设计实现的协议转换器系统板实现了rs232串行通讯口与以太网rj - 45接口的数据双向传输功能，也就是说可以完成rs232串行通讯口协议与tcp ip协议的协议转换功能。 |
| 5. | The system takes mcu as its kernel controller , which control pit - 8253 to produce control signal of the s3901 - 256lvf sensor . under the control of mcu , a / d collector starts to collect and convert the video signal into digital signal . finally , all collecting data are transferred into the personal computer through serial - port communication
该测试仪系统下位机以单片机作为控制系统的核心，控制pit - 8253产生控制信号，驱动探测器s3901 - 256lvf工作，在单片机的控制下， a d采集器对探测器输出的视频信号进行数据采集，并通过rs - 232串行通讯口与计算机进行数据通信。 |
| 6. | And the program is designed to convenient for using . the functions of supervisor system include data sampling and showing in real time , data saving , data printing , data showing through curve graph , alarm by sound and lamp . the running control function is accomplished through communicating with sub - computer
监控系统的功能是实现数据的实时采集、实时显示、数据保存、数据打印、曲线图显示、声光及语音报警，并通过串行通讯口和下位机运行控制器通讯来实现运行的自动控制。 |
| 7. | The largest baud rate of transfers is 19200bps which means that the converter has practicability . any boat carried facilities with the rs232 serial communicating ports can be connected to the ethernet of the boat carried facilities integrated system by connecting to a switch . the dissertation consists of six chapters
该协议转换器软件采用客户机服务器模式编制，可达到的最大传输波特率为19200bps ，具备实用性，任何具有rs232串行通讯口的船载设备都可以通过该协议转换器与交换机相联接入船载设备集成系统以太网络。 |
