我正在尝试通过RS232与E3647A进行通信,并且我不断出现帧错误,而我假设的其他一些错误是由于通信不当造成的。
握手的描述在手册中不是很清楚; 该怎么办? 此外,串口是否可以在TTL或真正的RS232电压下工作? 以上来自于谷歌翻译 以下为原文 I'm trying to communicate via RS232 with an E3647A and I keep getting framing errors, and some other various errors that I'm assuming are the result of improper communications. The description of the handshake isn't very clear in the manual; how is it supposed to work? Also, does the serial port work on TTL or true RS232 voltages? |

我有一些问题:你用什么来沟通?
你使用合适的电缆类型吗? 电缆手册中有说明。 您是否下载了Keysight IO Libraries以查看它是否可以在那里运行? 您是否可以访问GPIB控制器,它比RS-232更加强大和可靠。 以上来自于谷歌翻译 以下为原文 I have some questions: What are you using to communicate? Are you using the proper cable type? There is a description in the manual for the cable. Have you downloaded the Keysight IO Libraries to see if it works there? Do you have access to a GPIB controller, it is much more robust and reliable than RS-232. |

我已经尝试使用Matlab和RealTerm作为我电脑上的通讯软件。 我经常使用它们与其他设备进行通信,所以我觉得一切都可以用到我的USB端口。 对于电缆,我有一个USB-RS232电缆,引线焊接到一个母DB9。 电缆使用TTL电压电平,没有DTR / DSR。 此刻,我将引脚4(PS DTR)打开,引脚6(PS DSR)连接到Vcc,并关闭流量控制,以试图绕过握手。 我下载了IO库,Connection Expert似乎没有认识到它。 我有USB-GPIB电缆,但更喜欢在这个应用中使用RS232。 谢谢 以上来自于谷歌翻译 以下为原文 I have tried Matlab and RealTerm as the communications software on my PC. I use both regularly to communicate with other devices, so I think everything is OK up to my USB port. For the cable, I have a USB-RS232 cable with the leads soldered into a female DB9. The cable uses TTL voltage levels, and does not have DTR/DSR. At the moment, I have pin 4 (PS DTR) open, pin 6 (PS DSR) tied to Vcc, and flow control off, in order to try to get around the handshake. I downloaded the IO libraries and the Connection Expert doesn't seem to be recognizing it. I have USB-GPIB cables, but would prefer to use RS232 for this application. Thanks |

好学的东东 发表于 2018-9-17 07:27 如果连接专家没有识别它,则设置存在问题。 有关如何设置RS-的详细信息,请参阅[http://literature.cdn.keysight.com/litweb/pdf/E3646-90001.pdf?id=1000000671:epsg:man]手册的第57页。 232连接。 以上来自于谷歌翻译 以下为原文 If connection expert is not recognizing it, then there is an issue with the setup. Please refer to page 57 of the manual at [http://literature.cdn.keysight.com/litweb/pdf/E3646-90001.pdf?id=1000000671:epsg:man] for details on how to set up your RS-232 connection. |
