The error message appears on the ViRead command. |
|
Try adding termination characters, for example: instrument.setReadTerminationCharacter('\n');
instrument.setReadTerminationCharacterEnabled(true);
instrument.setWriteTerminator("\n");
instrument.queryString("*IDN?");Here is where to check what termination character MI MAX uses:

I try to add your informations, but i have the same result after Instrument.QueryString() |
|
Please post a screenshot of the I/O Settings tab in the window which opens from NI MAX |

this is the 3 screens of NI-Max and NI I/O Trace |

Thanks for the screenshots, they are helpful. Can you also post the Java code you are running? |

Try removing sCommand = "*IDN?"; |

I try to remove the "\n" after "*IDN?" but it is the same thing, I have a timeout |

Let's compare all the Visa attributes between NI MAX and our program, can you run this right before sending System.out.println("RSRC_NAME " + instrument.getAttributeString(JVisaLibrary.VI_ATTR_RSRC_NAME));
System.out.println("INTF_TYPE " + instrument.getAttributeBytes(JVisaLibrary.VI_ATTR_INTF_TYPE)[0]);
System.out.println("RSRC_CLASS " + instrument.getAttributeString(JVisaLibrary.VI_ATTR_RSRC_CLASS));
System.out.println("TCPIP_HOSTNAME " + instrument.getAttributeString(JVisaLibrary.VI_ATTR_TCPIP_HOSTNAME));
System.out.println("TCPIP_ADDR " + instrument.getAttributeString(JVisaLibrary.VI_ATTR_TCPIP_ADDR));
System.out.println("TCPIP_PORT " + Arrays.toString(instrument.getAttributeBytes(JVisaLibrary.VI_ATTR_TCPIP_PORT)));
System.out.println("TCPIP_NODELAY " + instrument.getAttributeBytes(JVisaLibrary.VI_ATTR_TCPIP_NODELAY)[0]);
System.out.println("TCPIP_KEEPALIVE " + instrument.getAttributeBytes(JVisaLibrary.VI_ATTR_TCPIP_KEEPALIVE)[0]);
System.out.println("TMO_VALUE " + Arrays.toString(instrument.getAttributeBytes(JVisaLibrary.VI_ATTR_TMO_VALUE)));
System.out.println("SEND_END_EN " + instrument.getAttributeBytes(JVisaLibrary.VI_ATTR_SEND_END_EN)[0]);
System.out.println("SUPPRESS_END_EN " + instrument.getAttributeBytes(JVisaLibrary.VI_ATTR_SUPPRESS_END_EN)[0]);
System.out.println("TERMCHAR_EN " + instrument.getAttributeBytes(JVisaLibrary.VI_ATTR_TERMCHAR_EN)[0]);
System.out.println("TERMCHAR " + instrument.getAttributeBytes(JVisaLibrary.VI_ATTR_TERMCHAR)[0]);
System.out.println("IO_PROT " + instrument.getAttributeBytes(JVisaLibrary.VI_ATTR_IO_PROT)[0]); |

Here are the results of the different functions: |
|
Thanks for posting the result. It looks all the values from your code match the values in the NI I/O Trace screenshot. I will keep thinking of ways to debug this problem |

Hello,
I try to use IP adress with Socket Port like : "TCPIP0::10.10.0.8::5025::SOCKET", but i have an error message of connection as soon as I run the "openInstrument" command.
Could you help me to try a solution ?
Kind Regards
