Safenet and port 6001
We have been using the USB-6008 in our products for some time. We also use the Safenet hardware protection keys. These are hard coded to use port 6001 and 6002. It seems that up until this week, there was an option of setting registry entries to insure that the National Instrument software did not use these ports. Otherwise it seems to default to ports 6000-6007.
In the last week, installations have been failing and no longer appear to reconize the registry entries. Is there some new procedure to get the system to leave the ports 6001 and 6002 available?
Are there specific modules which can be eliminated from the installation which will avoid this conflict? We only use a few API calls from a C program to access the USB-6008 device.

connecting current sensor and voltage sensor
I am new in NI products. I would like to know how to connect a current sensor LEM HASS 50 S and voltage sensor LEM LV 25-P to a SCB68a. The SCB68A is connected to a PCI7841R. I will be using LABView 2013

C# write to USB-6001
I already have a task created in MAX.
I am loading the task using Task Setpoint_Task = NationalInstruments.DAQmx.DaqSystem.Local.LoadTask("Setpoint");
The channel is called AO-0 in MAX.
I am not sure what I need to do to set that channel to 5V.

Accelerometer
I am having trouble connecting a single-axis accelerometer to our USB-6210 DAQ. The accelerometer needs a maximum power supply of 5V, but we have an external power supply available if necessary. We can't figure out which terminals we need to connect the accelerometer to since we can't seem to actually get any data during our tests. I attached an image of the accelerometer to show what connections are necessary. If anybody could help us with this, we're pretty lost and would appreciate it!

How to fine tune 24VAC for SCXI-1160 1324
Good day,
I'm searching to fine tune the 24VAC (which is now suprisingly 28VAC).
We are using NI-PCI-6030E, SCXI-1001 chassis with 1160 & 1324.
In code (vi), I see that just a relay is switched to power our module to test (wanted 24VAC).
SC1Mod4/ch0 or 1.
I assume that I have to define the 24VAC with Measurement & auotmation explorer? NI-488.2 interactive control? or NI-DAQmx Configuration tool?
I'm new in this stuff and have to maintenance an old system..
best regards,
koen.

Problem with task not writing to file
I have a problem where the file writing from a analog reading task will eventually stop working. The acquisition will work normally but after a period of time (tens of seconds to tens of minutes) it will stop writing files.
The mode of operation is to continuously acquire and periodically switch to a new file.
The key functions are 'readTaskConfigure()' and 'AnalogInCallback()'. The 'ShowWaveforms' flag is set to false.
I suspect the problem is with resource usage. Any suggestions on how to make this more efficient would be greatly appreciated.
Thanks,

Error -200279
Hey!
I try to logg and also show data in a chart! However, it only runs when I remove the chart. Otherwise I get the error:
Error -200279 :
Possible reason(s):
Attempted to read samples that are no longer available. The requested sample was previously available, but has since been overwritten.
Increasing the buffer size, reading the data more frequently, or specifying a fixed number of samples to read instead of reading all available samples might correct the problem.
It seems that the initialization of the chart is too slow and data is already lost when its ready to run.
How should I build the system up otherwise?
Thank you for your help!

NI 9265 has external power of 24 volts but the output channels only read 7 volts
Hello,
I have a cRIO 9076 with two NI 9265 modules, one NI 9207 module, and one NI 9482 module. The issue I am having is with the NI 9265 modules. I am using an external power supply to provide 24 volts to the module but each of the output channels reads either 7 volts or 13.2 volts. I need the modules to measure 24 volts for each channel in order for the system to function properly. Does anyone know what is wrong or what I need to change to fix this problem? Thanks for your help.

DAQ 6036E not working in parallel - NI-MAX-Bug?
Dear all,
I am stuck with a strange issue with two PCMCIA-6036E cards running on adapters on a W7 32-bit desktop machine.
The adapters are two Texas Instruments PCMCIA-adapters in PCI-slots (both show different IRQ in the windows device manager).
But NI MAX (5.6.0f0) only recognizes one card, no matter what I do.
Card 1 alone works in both adapter slots
Card 2 works alone in both adapter slots
But as soon as I place the second card in the other slot (no matter which combo thereof), it does not show up in the NI-MAX device manager (itshows up in windows' device manager, though).
I noticed that the card's serial number displayed on the NI-MAX overview tab is not updated if I exchange cards - though I can see the valid serial number in the "attributes" tab, respectively.
Renaming (Dev1 --> Dev2) does not do the trick.
I suspect some sort of software issue; perhaps connected with the unchanged serial number. It appears as if NI-MAX is ignorant of the second card although they (and the adapters) appear to be clearly distinguished by windows. Perhaps an internal update issue?
Another symptom: I plug in card 1 and test it (works), I additionally plug card 2 (not recognized) then I remove card 1 and NI-MAX still tells me that a card is installed. But the serial number is not updated and testing/self-calibration fails.
I did not find any mention of such behaviour. I now have to work with two separate computers which is awfully annoying.
Any suggestions? Has this been filed as a bug or are there known compatibility issues with the PCMCIA-Adapters?
Thanks for reading!

error 200279 when using DAQmx at 5 KHz
Dear all,
I meet error 200279 at the first few senconds or running the VI for 1 minute. The VI is quite simple, I just use 5 channels to read the data. I've tried to increase the sample to read from 2.5K to 4K and to 5K. It seems make no difference.
BTW, the same VI works well with another PC (the same 6356).
What should I do to solve this problem?
Thanks

Omega USB Temp
Hi Guys,
So I just learned labview last week 
its really fun, now the question.
- I am using an OM-USB-TEMp Module to take some temperature measurements. Omega has supplied with some of the Sub VI's so that i don't have to code as much
- Writing to Excel though has been giving me some trouble, I keep getting an error of a "you have connected two terminals of two different termial types" I tried to use the Bundle option nothing. I have attached my program below if anyone can help
thanks

How to save all data into a file?
Hi
I attached a vi. I included 'Write to Text File Function' in the block diagram. It works. But this can save just single data.
This cannot save whole accumulated data.
Could you help me how to accumulate all data(from begining to the end) into a file?

Time since DAQ Power On?
Since the calibration of a device is sensitive to temperature and given that the user manual recommends that a device is allowed to be powered for a period of time before using it, is there a way to read back from the device the time since it was powered on?

SCB 68 - Measure Temperature with thermocouple type K single ended
Hello all,
I want to use a thermocouple to measure the Temperature of a heater. Referring to the "SCB 68 User Manual for Advanced Functions" (http://www.ni.com/pdf/manuals/372551a.pdf) we installed a resistor at position A and connected the thermocouple single ended as shown on page 4-6.
My Problem ist: Is this installation correct?
I dont really understand the funcion of the resistor and how to measure the temperature now. When i want to measure the temperature with MAX, he expect a differential-measurement.
Thank you for your help.
Best regards

NI 9207 only reads 2 of the 5 wired current input channels
Hello
I have a NI cRIO 9076 with two NI 9265 analog input modules, one NI 9482 relay module, and one NI 9207 analog input module. The NI 9207 module has 5 lines wired into current inputs. There is also an external supply voltage of 24 volts supplied to the module. The module is used to read data from three flow meters, a pressure gage, and a flow meter. The first two current inputs from the first two flow meters reads correctly, but the last three do not read anything. I am not sure what the issue is. Any ideas? Thanks for your help.

PCI-6070e (PCI-MIO-16E-1) broken capacitors values ?
I have a PCI-6070e (PCI-MIO-16E-1) DAQ card. The problem is that some of the smd capacitors mounted on the back of the card are broken/missing. The card is:
Serial Number: 014B60A1
Version: 183455R-01
Copyright 2004
Made in Hungary
The broken capacitors are; C49, C57, C65, C66, C67, C100, C104, C111, C112, C113.
I believe that the card could be repaired, because it passes the reset, self-test and calibration tests. But I suppose its performance is affected by the missing capacitors.
I will be very thankful if someone could tell me what the values of these capacitors are.

Measuring temperature rise up to 800 degrees Celsius with USB-6009
Hi,
I have a USB-6009 DAQ and Signal Express software and would like to measure a rise in temperature. Would it be possible to do so?
I have an instance were I need to measure the heat transfer through a series of sample plates coated in differing thickness of intumescent paint.
I will be applying around 800 degrees Celsius to the coated side and would like to measure the temperature difference and rise time on the other side of the sample.
I have a series of K type thermocouples which I will be using, should I use somesort a cold juction compensation?
Many thanks for any advice.

NI 9265 analog output channel stops responding
Hello
I have a cRIO 9076 with two NI 9265 modules, one NI 9207 module and one NI 9482 module. I am having an issue with the analog output from my NI 9265 module. I am using it to control air actuating ball valves and it works fine except when I go to open the ball valves by more than 30%, say from 60% closed to 30% closed. When this happens the module seems to lose contact with that channel. It becomes unresponsive to my inputs and I am no longer able to control that ball valve. If I restart the system it regains contact with the channel and is able to perform normally until I try to open the ball valves by at least 30% again. There are also quick disconnects for the ball valves and if I disconnect this and then reconnect it, it goes back to performing normally. I am not sure if there is a setting that I could change that would fix this problem? I have a cFP system that performs the same operation and it is easily able to handle this type of action. Any ideas? Thanks for your help.

daqmx DAQmxCfgDigEdgeStartTrig simulated
Hi.
I am developing under LabWindows on a Simulated device Daq PXIe-6363
I use two tasks (one to send data, the other one to receive)
I need to synchronize the tasks.
I started with the example SynchAI-AO.c
In this code, DAQmxCfgDigEdgeStartTrig is called for the AOtask.
I just added a call to DAQmxRegisterEveryNSamplesEvent for AOtask, and I see that the callback is called even if task AI is not started .
I thought that the AO task will only start when AI task is started (due to the call to DAQmxCfgDigEdgeStartTrig )
Do I misunderstand something ?
Is it because I am running with a Simulated device (and it will work as I thought with real hardware ? ) ?
Thanks
