Hello!
I'm just starting to work with the device. I have a few questions.
Can I make a triangular reference signal?
Can I transmit the reference signal via GPIB?

Mounting RMC 8356 Rack Mount Controller
Can I use the RMC8356 on a rack with a front-back rail distance of 25.25" (640mm)?
When try to compress the rack rails to this dimension, they fall apart.
Is there a minimum front-back rail distance for mounting the RMC835? Where is that specified?

The "Acquire Input Data.vi" does not recognize the keyboard layout correctly.
The "Acquire Input Data.vi" recognizes the keyboard layout as an English layout, although the layout is actually German.
The Expectation Value:
- The "Acquire Input Data.vi" automatically recognizes the currently active keyboard layout. (under Windows any keyboard layout can be selected).
Questions:
- Why does "Acquire Input Data.vi" not recognize the keyboard layout correctly? What should be done about it?
- There is a "Language Identifier Constants and Strings Table" from Microsoft. Should the table be used? If so, then I have unfortunately not understood how.
Additional info:
LabVIEW 2016
Windows 10-64bit (image 1809)
Thank you in advance for your support!

NI USB 4431
Greetings!
I have some issues with USB-4431, NI-DAQmx driver was properly installed and the instrument already appears on Device Manager. But I can't find it on MAX and when usb cable is plugged in, the instrument LEDs does not light up. I'm trying to use 4431 for triggering a seismic source.
Anyone can suggest a solution?
Thanks in advice

GNURadio with USRP-2944R
I have a USRP-2944R which I would like to initially work with GNURadio. I created a blcok diagram with the "UHD:USRP Source" block but don't know how to get it to address the 2944R over PCIe interface. Specifically what do I use for "Device Address and Arguments"?

Legacy NI-488.2 drivers for Windows 2000
I usually only check the NI-488.2 driver page for newer drivers, but I thought that at least in the last few years older drivers were still listed on the driver page. I can't find anything older that windows XP for driver support.
For an old legacy machine we have that came with Windows 2000 (and will not be upgraded) we had two internal GPIB cards installed. The machine had the drivers pre-installed when delivered, but someone either uninstalled them sometime recently or someone wiped and restored the machine. After 15 yrs no one will know what happened to the original NI-488.2 installation CD that came with the machine.
We need a NI-488.2 driver package to install on the machine (it must be an offline version, the machine will have no internet connectivity). I don't know exactly what version it would take, something probably back in the 1.x days, maybe even 2.x, I would assume.
Any link to a legacy driver page would be greatly appreciated.

Unable to do iviSessionFactory.CreateDriver for NI ykdlm2000 IVI-driver
Hello!
Im trying to connect to a Yokogawa DLM2054 using the NI-IVI driver referenced by Yokogawa https://tmi.yokogawa.com/solutions/products/oscilloscopes/digital-and-mixed-signal-oscilloscopes/dlm2000-mso-series/#Documents-Downloads____downloads_6
When the driver was installed, it showed up as expected in MAX, but with ProgID field empty
When trying to start the driver in C#, i get an exception
"IIviSessionFactory: Software Module (ykdlm2000) has no Prog ID"
from the line below
IIviScope scope = (IIviScope)iviSessionFactory.CreateDriver("ykdlm2000");
If I add some random data to the Prog ID field I get exception
'IIviSessionFactory: Driver Session CLSID (foobar) not registered'
from the line mentioned above
DL-Term from Yokogawa works fine, so I dont think there is a problem with the USB-connection.
Any ideas on what can cause this?

USB RAW error 0xBFFF003D and 0x3FFF0082
Hello, newbie to USB RAW here. I am attempting to communicate with a packaged system from Newport Insturments. It is a power supply that controls a lamp and is connected to a monochromator (in series) and then to a filter wheel (in series with the monochromator. At the moment I am trying to establish a connection to the power supply through a USB. This system comes with a LabView program to control the various aspects of the device (for example turning the lamp on and off/running selected scans). However; I would like to incorporate the functionality of this system with other devices through my own labview code. Unfortunately the program is compiled and the support from Newport is terrible, so there is no driver or example VI's. When the provided utility is working properly the system shows up as a portable device in the device manager. So I have begun trying to communicate with the device through VISA. The RS232 commands are listed in the manuals provided at the end.
I have been able to use the NI-VISA driver wizard to create an INF file for this devices as described here . When I try and install the INF I have to turn off the signature checking as described here . When I do this it doesn't create a PNF as expected, but it does seem to modify the oem29 INF and PNF files. Even so, I can now change the driver in device manager. It now shows up in device manager under NI_VISA USB Devices drop down menu as Newport POWER SUPPLY, and shows up as a USB RAW in NI-MAX.
If I open NI-MAX I can write to the device without error, but when I try and read I get the error:
Read Operation
Error
VISA: (Hex 0xBFFF003E) Could not perform operation because of I/O error.
When I look further and check the attributes at the bottom of the list (in red) that the attribute interrupt in pipe status has an invail property, double clicking on that shows the error:
Error
VISA: (Hex 0x3FFF0082) The specified object reference is uninitialized.
where the attribute "Interrput in Pipe" shows a -1 in Current Value (this is true if I refresh the list and open the test panel without running a read function). The Bulk Out Pipe Status has a value of READY, while the BULK In Pipe Status has a value of STALLED?
I'm unsure what these errors could mean, any advice would be greatly appreciated.
I am using LabView 2018, 64 bit with Windows 10.
The manuals for the entire system is here. While the standalone power supply ( which is what I am trying to communicate with is here .
If anyone can offer advice that would be appreciated. Thanks in advance.

SR830 lock-in-amplifier programming
Hello!
I need to send a signal via GPIB to the AUX OUT using a labview.
I can pass one value in volts with a command.
But I don't understand.
Do I need to write a cycle in which I will consistently transmit voltage values for each point in time?
or can I create a signal in labview (using ready-made components) and transmit it completely?

NI VISA Configuration - interface USB manquant
Bonjour à tous,
Je me retrouve devant un problème qui nécessite vos conseils.
Je souhaite piloter par USB le multimètre Keithley 2110 5 1/2 Digit multimeter
J'ai installé NI-VISA pour Linux en suivant la procédure:
http://www.ni.com/download/ni-visa-17.0/6700/en/
L'appareil est facilement pilotable avec NI VISA sur Window mais avec "OpenSUSE 42.2 Leap" (système d'exploitation préconisé par NI) le cas se corse.
Je suis passé par les outils NI pour vérifier si l'appareil est détecté avec "OpenSUSE 42.2 Leap".
Il semble que l'appareil n'apparaît pas (voir les photos ci-joints) :
- NI VISA Configuration -->"USB" n'apparaît pas au niveau des choix d'interface
Pourtant, la librarie "libnivuusb.so" (passeport USB) est bien présent.
- NI VISA IC --> pas de port USB reconnu.
- NI VISA Driver Wizard -> choix USB pas sélectionnable
J'ai écumé pas mal de forum, tutoriel mais je tourne en rond.
Quelqu'un saurait comment faire pour utiliser l'USB dans les outils NI (le rendre sélectionnable ?
Merci pour vos réponses.

NI-488.2 installation on Windows 10
NI-488.2 V15.5 or newer can support Windows 10, however the previous release e.g. V14.0 can install on W10 as well. Furthermore the new version cannot be installed successfully if the previous version is not uninstalled. Then how to uninstall the previous version via command line? The installation was called by "Setup.exe Spec.txt /q /r:n".
Thanks in advance.

GPIB PCIe card communication with Keithley DMMs and SMUs occasionally freezes also in NI-Max/ No problem with USB-HS+
Hello, while trying to read the buffer of a Keithley DMMs or SMUs (2450 e.g.) many times fast enough the in NI-Max freezes, no response and needs to be killed in task-manager. Same happens using .NET in Visual studio. After changing to the USB-HS+ this issue is gone. Is there a solution for that problem to be able to use PCIe-GPIB card?
NI-MAX 18.5, also latest firmware at Keithleys

Multiple command in LabView via RS-232 by New focus 8753
When I sent a command writing in a string at one time, a picomotor actuator was worked. But when I wrote all commands in in one string, the actuator didn't work. The problem is about sending multiple command and controlling multiple picomotor actuator Simultaneously, how do I modify my LabView code that can send multiple commands to control one or more actuator?
P.S
1.Commands are in manual(Page 67)
2.Serial setting： Baud rate=19200, data bits=8, parity=none, stop bits=1 ,and flow control=none.

Firewall blocking communication
Hi,
I tried the Hello World program to connect to a device via ivi. When the firewall is enabled I get an Error:
var resourceString2 = "TCPIP::10.25.46.125::hislip0"; GlobalResourceManager.Open(resourceString2) as IMessageBasedSession;
Unzureichende Angaben zum Speicherort oder das Gerät/die Ressource ist nicht im System vorhanden.
bei Ivi.Visa.GlobalResourceManager.Open(String resourceName, AccessModes accessModes, Int32 timeoutMilliseconds, ResourceOpenStatus& openStatus)
bei Ivi.Visa.GlobalResourceManager.Open(String resourceName)
What ports do I have to open in the firewalls to allow communication?

Communication between pc (c#) and microprocessor via USB- VISA driver
My lecture has given me a project with the name above. The microprocessor I'm intending to use is STM32F407 (the only one I got). Can someone help me to specify what exactly I have to do now? I have no idea about NI VISA driver and also USB protocol ( usually I use USB-COM). If possible, please share with me a similar project. Thank you so much for your support.

VISA - Queueing
Hi,
I having a problem to read data from ADC transmitted from pic18F4580 via UART. The data transmitted reads from 8 ADCs plus with 0 (originally is *END* which is marked for end of iteration).To complete 1 frame data requires 12 iterations. Therefore for each iteration there will be 9 measurements data. I build a VI using VISA and queue/ dequeue functions to make sure all measurements are available for the next process. When I run the VI, no data are displayed on the front panel. Any advice or what did I missed here?
Regards
Ledang
