Can I generate 'dry contact input ( or free volt contact input)' using NI-9472?
Hi
I'm trying to control some equipment which allows remote control by dry contact input.
As I have labview program and NI-9472 to control solenoid valves, I want to add function to control dry contact-operating equipment.
So, can I make dry contact input using NI-9472?
I'm a novice in this fields, I'm not that knowledgeable in this part. So it would be so glad for your help
Thank you

Error 10609
Got "Error 10609 occurred at AI clock config"
possible reasons:
NI-DAQ LV: A transfer is already in progress for the specified resource, or the operation is not allowed because the device is in the process of performing transfers, possibly with different resource.
I am trying to run an old labview code which connects to a laser system. I was trying to correct an error (-1073807339) by playing around with the time out value and then I suddenly started getting the 10609 error as well. The code was running until yesterday. I don't understand what could have caused this error msg. I also tried restarting the computer a few times. Can someone please help me out? I am using Labview 8.5 with a PCI-MIO-16E-4 device.

How to create NI-VISA driver for PCI device on NI Linux Real-Time
Hi all,
Wondering to know if it is possible to create an NI-VISA driver for a PCI device connecting to the NI Linux Real-Time operating system?
As far as I know, NI-VISA Driver Wizard could generate ".inf" and ".ini" files for windows. But they are useless for NILRT.

PCI 6509
Hello NI Community,
I have a NI's 6509 PCI card, which is being used to monitor/Control the test systems.
There is a LabVIEW utility that is being designed to achieve the above the purpose.
I had to format the PC in which this was installed due to some reasons and after completing the new installation of Windows XP OS,installing the NI-DAQmx 14.5 and the LabVIEW utility, i expected to run every thing as usual. However, the LabVIEW utility is getting crashed when tried to run with the error "
Error 1 occurred at Flush Queue in EMS1722_Test_Screen.vi->EMS1722_Main_Screen.vi->EMS1722_User_Authentication.vi
Possible reason(s):
LabVIEW: An input parameter is invalid. For example if the input is a path, the path might contain a character not allowed by the OS such as ? or @.".
I also tried installing NI-DAQmx 9.8 but result was same.
Anu suggestion on this would be helpful.
Thank you.

Or does anyone has experience in writing a matlab device Driver?
I would pay Money if anyone gets my Scope working with Matlab.

USB-GPIB communication with spectrum analyzer
Hello All,
I should automatize laboratory.
Actualy, i need to create VI that have all major functions of specrum analyzer.
Spectrum analyzer is Rhode&Schwarz FSP. Doc in att.
Communicatin should be done via Profilogix GPIB - USB controller. Doc in att.
Because this area is compleatly new for me, i would like to ask you, if somebody can advise me how i can start with this?
I already asked Rhode&Schwarz for some example, but they hdon't have it...
Also, because PC will communicate over USB, is it ok to use VISA functions?
Thank you very much for support.

Recording GPIB Commands for Playback
Hi,
I am recording GPIB commands with the NI I/O Trace Software and would like to replay them/send them to an instrument. Is this easily done with one of the NI Tools? if not, does anyone recommend a third party tool for sending GPIB commands? The commands that I would like to send range from 1 to 705 Lines.
Thank you!

Try to use a multimeter with gpib32.dll and mingw32 application
Hello NI experts,
I am trying to develop an application with mingw32 (windows 7 - 64 bits) to control an external multimeter via GPIB. Manual explanation (370428.pdf) seems pretty forward. There is the direct access method (case 1) using the gpib-32.dll (or ni4882.dll).
Case 1 is not working. I am using the code found in the direct access examples.
ni4882Lib = LoadLibrary ("C:\\Windows\\SysWOW64\\gpib-32.dll");
I tried both gpib-32.dll or ni4882.dll (using respectively ni488.h and ni4882.h in my code). It seems the dll cannot be loaded.
I also tried the solution (case 2) from an old post on this forum as the setup seems similar.
In this case, I have created the object file from the dll. So far I am able to compile using directly the API. But as soon as I am running my exe file in the enduser software. I have a timeout and it stops (even code is not going through any of the ibxxx command).
I miss probably something but I cannot figure out what (32 bits / 64 bits / compilation options / ...)
Any advice on either case 1 or case 2 is welcome.
Thanks in advance for any suggestion

Use of Non-Contact Level Transmitters for Harsh Chemicals
The best solution for harsh chemicals can be a non-contact level transmitter. These do not come in contact with the chemical and use other methods for measuring the chemical level. Radar level sensors or ultrasonic level sensors are the best choice for harsh chemicals.
However, it must be kept in mind that these level sensors may be prone to other measurement obstacles. Foam and thick vapor can considerably hamper the performance of ultrasonic sensors. In the case of radar sensors, fine-tuning it to avoid these problems can be a cumbersome task. To add to the woes, consider the high price of radar sensors. Besides, the danger of splashing and vapors from harsh chemicals remains, even in the case of these level transmitters.

Is there any problem with the 485 board card of NI's pxi8431/8?
The idle level of output in 2-wire auto mode is 0v, shouldn't it be logical high +5V? Check some data that there is no bias resistance, but the bias resistance how to add, no one can explain in detail. How to solve this problem, hope answer!

Connecting to Old Instruments Having +-12V RS232 Voltage Levels
Hi,
I have an old piece of instrument built in the 1980s. It requires +-12V voltage levels for the RS232 interface. My eBay USB to serial dongle doesn't work. Can someone suggest a PCI or PCIe card that can reach +-12V? For example, can NI's PCI-8430/2 do the job? I found the following table in the file http://www.ni.com/pdf/manuals/373170f.pdf, where the "Driver output" is listed to be 5 to 25V. Is this the voltage level of the signal, such as the "Data Treminal Ready" (DTR)?
