Can I configure a voltage divider on a SCXI-1100 card in order to read a 24V DC signal without external circuitry?

I would like to know if I can configure a voltage divider without having to wire external circuitry. I know that there are pads for a filter capacitor and current to voltage resistor on the SCXI-1100. COuld these pads be used to solder in a precision resistor to serve as a voltage divider? The voltage I am trying to measure is a 24V DC signal."

Hello;
The pads you can see on the 1100 are pretty much bread boards that you can use to build your own circuitry on.
You can build a voltage divisor on that space, just make sure to follow the current specs of the SCXI module.

How I can measure frequency of TTL signal without external clock?

Hello,
I want to measure frequency of TTL signal using PXI-6254 or PXI-6713, without using external clock.
Frequency will be up to 100kHz. How I can use internal counter of 20MHz or 80MHz?

Hi Yuta K,
You have not stated what software you want to use for this measurement, but in case you're using LabVIEW, please go to the Example Finder (in LabVIEW go to "Help >> Find Examples").
In the Example Finder, you make sure the "Browse" tab is stil selected, and than you go to:
Hardware Input and Output >> DAQmx >> Counter Measurements >> Digital Frequency
Here you will find some good examples of measuring a digital frequency with 1 or 2 onboard counters.
If you need additional information, please let us know!

Voltage Measuring error in Labview with scxi-1100/1300

I used the Daq wizard to setup my simple loop to measure 6 channels on my SCXI-1100 card with 1300 terminal. I actually measured the voltage on the terminal block and get 4.6 volts but labview reads from 1.1 to 0.8? I believe it is something I setup wrong in NI-MAX or my simple labview loop because we switched out the 1100 & 1300 cards - any suggestions on what to check next? Could my PCI card or SCXI Chassis be causing this problem?
thanks

Yes. I am sure it's something simple that I am not doing but I am stumped!
I have the following setup:
PCI-MIO16E-4
SCXI-1001
SCXI-1100/1300
When I open the test panel it reads the real voltage (that I confirmed on the terminal block with a voltmeter) but when I run the sample program or a simple Daq Assistant scan the numbers are completely different. I attached screen dumps - please take a look and see if you can catch what I have set wrong etc.
thanks again!

How can I configure NI PCI 6221 and DAQ SCB-68 for pressure sensors?

Hello
everybody,
I am using the measuring board (NI PCI 6221) and DAQ
SCB-68 for the data acquisition.
With the DAQ-Assistant I created AI for the voltage of
pressure sensors. In a big indicator panel from this DAQ-Assistant I see the
voltage for both sensors in the correct size. But if I set sensors in the
blockdiagramm to control the signals for sensor one I get a wrong voltage size
and for sensor 2 nothing.
How can I configure this data acquisition equipment to
get the correct signals?
Thanks a lot for your help.

I do not know the type of sensor you are using. But pressure transducers may have a very low output voltage(in the mVolt range). They also need an excitation voltage. Here is an introduction. http://focus.ti.com.cn/cn/lit/an/sloa034/sloa034.pdfThen working with pressure sensors I always use 3 stages in the circuit.
1 Instrumentation Amplifier as a preamp
2 filterstage
3 Final amp and output buffer
(you may combine stage 2 and 3)
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
(Sorry no Labview "brag list" so far)

Thermocouple wiring with a Voltage Divider

Hello,
I am trying to measure the temperature through a K-type thermocouple by making a voltage divider connection. As you can see in the picture attached, I am wiring a resistor ( 10 kOhm) with the pins of the thermocouple to the DAQ (NI-6009).
The problem that I am facing is when running this with LabVIEW. I am attaching a file I created in order to control a heating element depending upon the temperature measurement. The result I get is -360.425 C which totally makes no sense, and makes me wonder what is wrong with either the .vi file or the wiring (I have checked the polarity of both the resistor and the thermocouple and that part should be solved already).
I am attaching a picture of the result since to obtain something everything needs to be wired first.
Thanks in advance
JL

It is hard to see how you have the voltage divider connected in the picture. Can you post an image of the schematic?
I never heard of anyone uisng a voltage divider on the output of a thermocouple. The voltage is quite small and dividing it makes little sense.
Next, the USB-6009 is marginally useful for measuring the output of a thermocouple. The resolution is about 1 degree.
Your formula for converting voltage to temperature is suspect. I do not have any hardware so I just generated an array of values from zero to 0.05. This results in temperatures on the chart of -97 to -87 degrees. For a Type K thermocouple 0 to 50 mV should represent temperatures from 0 to 1232 C.

How can i measure instantaneous voltage of an anlog waveform

Hi, All
I am new with LABVIEW need help urgently, and want to plot the stirling engine cycle PV graph, I have mounted suitable hardwares to the engine, pressure sensor with range of (0v-to5v) and position metet of range(0v-to10v) I have aquired both pressure and volume signals by DAQ assistant and BNC 2110. they are smoothly like sinusoidal waveform. How can I divide and measure at least 20 instantaneous voltage in one cycle and record the obtained data in two arrays for feeding XY graph wave form??. I have attached a simulation of idea for clarification. please attach your suggested code if you can thank you.

Hi,
If I get you right, you need to acquire signals from two sensors simultaneously and present the data in a xy graph.
So you should write your data from one whole cicle to two arrays, build a xy graph from that data and plot.
Since your new to LabVIEW I strongly recommend you to spend some time on the basic principles. This is a good start.

1v-5v output linearly by using 5v supply, voltage divider and variable resister

How can i get 1v-5v output linearly by using 5v supply, voltage divider and variable resister ?
"SB02"
Solved!
Go to Solution.

Do you have it wired like the attached file? Using my schematic, you can calculate the current through the pot based on the desired voltage drop across the pot
4V / 10Kohm = 0.0004 A
From Kirchhoff's current law, we know the same current will flow through the circuit so now we can calculate the lower leg of the divider based on the current and the desired voltage drop across the resistor
1V / 0.0004 A = 2.5K Ohm
My schematic keeps the current through the circuit constant so the voltage divider should never change. Assuming a linear pot, you will get a linear voltage swing as measured at the wiper. If you wired the pot a different way, then more then likely, you are changing the total resistance from 5V to ground which would effect the current which would effect the voltages.

Can I configure an external drive to be password protected or do I need to buy an external hard drive already password enabled

I asked at a Hong Kong apple shop if they had password protected external drives. They didn't, I bought one anyway.
I'm wondering can I configure this drive. If yes, what do I need to do?

This looks like the easiest and most direct method and since it uses Disk Utility it would work on any OS.

On the Mac in System Preferences > iCloud
Make sure Mail & Notes is selected.
ON the iPhone tap Settings > iCloud
Make sure Mail is switched on.
And try restarting your Mac and iPhone.

How can I configure my new Mac Pro to output the timeline via HDMI

How can I configure my new Mac Pro to output the timeline in FCP 7 (yes, I have X, but I'm using 7 right now). I have two monitors running from TB2, but want to have the third for a client monitor.
If I use all three via TB2, it's literally three monitors, and I want to edit on my CineDisplay. I only want the client to see the timeline video on the third monitor. When I hook up HDMI I get no signal, in fact, I can't have the HDMI cable hooked up for TB2 to work with the third.
Thanks,

If you use all ThunderBolt displays, or stick with DisplayPort and Mini DisplayPort (free conversion between the two with only a cheap cable) you can have up to six displays.
If you attach "legacy" displays with "any-old adapter", you can have up to two, and the built-in HDMI counts as one if you use it.
Any more requires ACTIVE Adapters.
The US$100 Apple ACTIVE Mini DisplayPort to Dual-Link DVI adapter works in every case, even displays over 1920 wide.
StarTech and Accell make US$35 ACTIVE adpters that work for displays up to 1920 wide.

How can I configure a mysql-database for new cms install?

I just install a mac os x server on os x 10.8.4, but can't create a database to install a cms, how can I do this ? How cann I access the database from admin window or else ?

Consider acquiring some external hosting as part of your efforts, then? Various folks offer this hosting, and that gets you out of maintaining (most of) MySQL and Drupal, and more time to spend on your web site and whatever else you're working on.
As for your questions, please follow the installation instructions for installing MySQL, then follow the instructions for installing Drupal. The OS X Server setup is basically the same as any other Unix system, too; what you're doing on Ubuntu is more or less the same as what you're doing on other Linux and Unix systems, and on OS X and OS X Server. (This is also at the core of why most of these add-on widgets expect you to set up your PATH, too.)
The Drupal database connections are managed under the sites directory, a subdirectory located within the Drupal directory tree. You'll find subdirectories for the specific Drupal sites you've configured there, with a settings.php file for each. There's also a general sites directory with modules and themes that can be applied generically. The settings.php file itself can be edited with nano, vim or emacs via the command line, or with one of a very few ASCII-capable GUI editors. If you don't know what I'm referring to here, use nano editor.
Yes, you can install phpmyadmin on OS X. I wouldn't, though. Sequel Pro has a much more familiar interface for folks that use OS X, and you don't have to protect that tool quite like you have to protect and maintain phpmyadmin against attack. Do not allow remote access to phpmyadmin, as ill-secured sites are a popular target for remote attacks.
The Drupal web forums are a pretty good resource for Drupal-related questions, too.

How can I configure ReFS to NOT fail read operations when a checksum error is detected (on non-Storage-Spaces volumes where data integrity streams are enabled)?

According to William Stanek, in his Windows Server 2012 R2 Inside Out: Configuration, Storage & Essentials book, this is apparently possible: (pg. 615 - here it is on Google Books: https://books.google.ca/books?id=0IyfBAAAQBAJ&pg=PT819&lpg=PT819&dq=read+operation )
Integrity can be enabled when the system is not running on Storage Spaces. When
integrity is enabled and ReFS detects a checksum mismatch, ReFS logs an event and
fails the read operation by default. If you don’t want the read operation to fail, you
can configure ReFS to continue with the read operation. A related event will be logged
regardless.
So then how do I configure it to do that???
(And just to make it super-clear, I'm NOT using Storage Spaces, so there is no redundancy via mirroring/parity, and I'm not expecting any file repair - just detection of corruption. It's just a basic volume formatted with ReFS and
with integrity streams enabled, via format E: /fs:ReFS /i:enabled
For those who want more details, here's the situation:
I try to perform a read operation on a file with corrupted data (purposely done for testing using a low-level disk editor), I get a the following error message:
And an event ID 133 from ReFSv1 gets logged in the System log:
Clicking "Try Again" just brings up the same message, and clicking "Skip" skips the operation entirely.
This is indeed the correct default behaviour.
What I want instead is for the read operation to be allowed to complete, with corrupt data and all, and ONLY for the event to be logged. And according to William Stanek, this is supposed to be configurable somewhere - and after hours of searching, I haven't
been able to find anything.

Hi Tommy,
>>How can I configure ReFS to NOT fail read operations when a checksum error is detected
We can use PowerShell command Set-FileIntegrity to configure this. The specific parameter for controlling this behavior is
-Enforce <Boolean>which indicates whether to enable blocking access to a file if integrity streams do not match the data.
Regarding this point, the following article can be referred to as reference.
