Some instruments require the LF regardless of the connection type. Otherwise, although VISA Read receives correct response, it finishes with timeout error since it still expects more bytes to arrive. To recognise the end of the response in VISA Read operations, you need to set the VISA attributes VI_ATTR_TERMCHAR_EN to TRUE and VI_ATTR_TERMCHAR to 0x0A.

In case of RawSocket and Serial connection, for VISA Write operations you always have to terminate strings with the LF character, because that is the only way to tell the instrument that message has ended. It serves as message termination character. ' ' is a Linefeed (LF) termination character, hexadecimally represented as 0x0A. There is a white paper provided by Rohde & Schwarz which has this to say: This doesn't impact the other 3 instruments but the HMC8043 still has a timeout error on the read. gvi project to set 'Termchar EN' to true and use the TermChar (I don't know what to hook that too but it defaults to .) I've pasted an image below. I have tried amending the Instrument profile in the. The HMC8043 is sent a command (*IDN? ) and I see a message pop up on the device's UI to tell me it has received it (the specific identification command.) The read always results in a timeout error. This works for 3 of my test instruments without a problem. In LabviewNXG I opened the VISA Simple Query.gvi example which can be used to send a SCPI command to a named test instrument. The HMC4083 (PSU) does require a terminator on a command to work correctly, the other instruments do not. In NI Max (and SystemDesigner) I can see these 4 devices and I can use the VISA test panel to send SCPI commands to each of them successfully.

I have 4 instruments connected through USB to my Windows 10 Pro laptop. I believe I have LabviewNXG and NIVISA 20 installed correctly but I have found that a bit confusing. I'm very new to Labview and I'm working through various videos and training courses. I would like to ask if those phenomena could be occurred by the problem related to LabVIEW or software? I got all confused because the instrument can be connected with Labview sometimes and it is random.Д¬ould you please give me any comments on those problems? I used supported commands of instrument and commands likeВ *IDN? . When I do Basic I/O test with VISA Test Panel and run Query or Read, I always see the errorВ 1073807339 (0xbfff0015). (Please ignore the different COM port number, I took the picture of failed connection result when I tried with different PC)Дў. Here are the results when the connection is successful and fails.Д®ven though the error has occurred, LabVIEW can recognize the COM port. When the connection is failed, LabVIEW shows 1073807339 (0xbfff0015) error. My instrument can be fully controlled by LabVIEW when the connection is successful. I need to repeat running and off executable LabVIEW runtime GUI program which is designed by the manufacturer 3 or 4 times to connect the instrument with my PC successfully.

And the port setting is consistent with the instrument manual (please refer to page 23, ).ДЎ. I'm pretty sure that there is no problem with COM port recognition. I've done the loop-back test and there wasn't any problem as well. I have checked the serial connection (COM port) first through NI-MAX and here is the result ( ). Program: LabVIEW 2019 (64 bit), NI-VISA 2019, LabVIEW Runtime Engine 2011 (32 bit, this is for operating my instrument with LabVIEW GUI)Д¬onnection type: USB to RS232 serial linkД®xecutable LabVIEW Runtime Engine file:В LUdriver_kit_example_V38 (I have attached zip file) Here is the information about what I'm currently using to operate my instrument.

So what I have to do is just connecting RS232 to my instrument driver kit and using LabVIEW runtime engine to operate my instrument. I downloaded an executable runtime LabVIEW file from the instrument manufacturer website. I referred to various solutions for errorВ 1073807339 (0xbfff0015), but I'm stuck with something different problem. I'm struggling to resolve the problem with errorВ 1073807339 (0xbfff0015).
