Can the AT-MIO-16E-1 output a given current ?

i was just wondering if i am able to output a specified current level by using the analog outputs, with my DAQ

The analog outputs on the AT-MIO-16E-1 are setup for voltage, but you could set generate a related current with external circuitry. This is not a trivial task. If you need to source current, I would recommend using the NI-6704 or a signal conditioning solution. More details about the 6704 board can be found at:

The signal conditioning solution I would recommend would be the 5B39. More details about the 5B modules can be found at:

Question about setup_MITE in the PCI-MIO-16E-1

I have a quick question about setup_MITE in the PCI-MIO-16E-1. In one of the manuals, it states that if you're using Dell Optiplex GX series for our hardware configuration, is it true we need to re-write the MITE functions to correlate with the hardware? Please if you can clarify what this means, I would really appreciate it. Thank you in advance.

Is the AT-MIO-16E-2 ISA card compatible with a Pentium III 1GHz with a 133MHz bus?

Is the AT-MIO-16E-2 ISA card compatible with a Pentium III 1GHz with a 133MHz bus? The system has an ISA slot available but I'm afraid the bus speed is too fast for this old card. Do I need to buy a new PCI card to work in this system?

Hello;
As long as your machine has a ISA slot and that the NI-DAQ driver is properly installed on it, you shouldn't have any problems with it.

MIO-16E-1 Output sample rate limited?

I have a program that I have used successfully on some old Pentium 2 computers. I recently purchased a new PCI-MIO-16E-1 board, and placed it into an AthlonXP 3000+ (2.1 GHz) computer (HP a700n). It seems that I have to limit my output sample rate to be less than 5kHz, where on the old systems the rate could be up to 1MHz. I am wondering if anyone has ran into the problem before or not?
I have tried the older MIO cards in this newer computer, and came with the same problematic result (no output).
I have also tried changing the output between IRQ and DMA modes (making sure the input channel is opposite).

Can you give some additional details of the behavior you are experiencing on the AMD computer? It sounds like if you increase the update rate beyond a certain rate, then your program executes but you don't see a signal on your AO channels. Is this correct?
Yes, Jeremy, this is correct. It seems that if we go above a 400kHz output sample rate, the signal either doesn't make it to the output buffer, or simply never gets placed on the AO of the board.
Are you checking for errors in your program? If so, do you get any errors? Are you using NI-DAQmx or Traditional NI-DAQ to communicate with your hardware?
Yes, we are checking for errors, and we get none. Using Traditional NI-DAQ, all responses are (0) as expected.
It also sounds like you are performing AO and AI in the same application. Have you tried to run a simple AO example that ships with NI-DAQ?
I was searching for an example to try when I though about trying a Pentium PC to see if the same thing happened. As far as I know, anytime our software has worked on any computer, I need not go back to trying samples, as they are typically more complex than what we end up with. We simply make a voltage array, and shoot the array to the board (After setting output rate).

Can the Apple TV gen 3 output audio at 24 bit/ 96 kHz?

Hi,
I have become aware of Apple Lossless music files (ALAC) which I believe are 24 bit / 96 kHz. I have established from the Apple TV specification that it supports Apple Lossless audio files. Does the Apple TV 3rd gen output in 24 bit/ 96 kHz? Thanks.

No, it outputs 48/16 or 48/12.

How can the Changes be seen in Output Message Cond. maint. for Purcha. Ord.

Dear All Gurus,
User had maint. the Cond. record in MN04 as for Com. code --> with Option - 5 email and Dispatch time as 4 , but as the P.o created then in Message tab the Cond. record populated as --> 5 External email and Dispatch time -3 (send with own trxn ), also i hd selected the output message line n click on Further data tab , new screen opens , here there is no tick on Manually ? Locked , this indicates that there is no any changes done in output in this P.O, but this also implies that what ever the cond. are created in MN04 , the same cond. are populated in this P.O, but user says that -> the cond record was maint. as with Option - 5 ( email) and Dispatch time as 4( Send immediately).Either the user is lying that the cond had maint correctly but may be the real situation could be that user might have created the cond with option --> 5 External email and Dispatch time -3 (send with own trxn ) and same is populated in this p.o created .
Here my question is that can we check that whatever the changes be carried out for that Co. code in trxn MN05 , is it possible to see those changes that on which date these changes were done , we have to convice this to user.
Rgds n thanxin advance.

a condition table is a customer table. if you want monitor changes made to records in such tables, then you have to prepare this in SE11 Go to Transaction SE11, enter table name and then click on 'Change' icon. In the next screen, click on 'Technical Settings' icon, the 'Log Data Change' indicator is located at the end of the screen.
of course this works only for changes made to conditions after this setting has been made.

AT-MIO-16E-10 Gate signal,how can i configure it as in input or as an output ?

Hi there ! I have AT-MIO-16E-10 board and i want to control a counter (the GPCTR0 counter of the bord) to count up depending on the gate signal.Now i have the following missunderstanding.I've read in the AT-MIO-16E-10 manual that the gate signal can be treated eather as an input or as an output.So i want to control my counter (to count up) until a signal that comes on my gate counter's entry changes his states from 1 to 0 (to reset the counter) and then when it changes his states back to 1 form 0 i.e a transition from 0 to 1 to start counting again from zero.Now here i have 2 questions : 1. How can i config the gate signal as an input signal (in the AT-MIO-16E-10 manual it sais that the signa
l can be treated as an input or output and it's known if i configure the port as an output and if i came with an external signal to the gate i can damage the board if the signal it's set to zero ) 2. What it's the default state of the gate signal ?
Any vi files would be very usefully,Thank you very much for reading this and i'll be waiting for your answers as quick as possible.

Antonios,
The shipping example VI Count Edges does what you describe.
>Quoted from VI Description
Count Edges (DAQ-STC).vi
DESCRIPTION:
This VI counts rising edges, using an STC based device (e.g.: E-series). The counter increments its event count everytime a pulse comes into its source input. A gate signal can be added such that if a low signal occurs on the gate, then the counter will pause (scroll the front panel left to access the gate settings). The current value of the counter is read continuously in the while loop, until the Stop button is clicked or an error occurs.
I/O CONNECTIONS:
Connect the gating signal, if any, to the gate input of the selected counter.
If you selected the Source Selection to be "PFI line", connect your event count base signal to the PFI line indicated by "Source PFI line number used". (If you selected "Internal Timebase", no source connection is necessary.)
NOTE: For actual I/O pin numbers, please refer to your hardware user manual.
INSTRUCTIONS:
1. Enter the device and counter you want use.
2. Make your Source selections, as desired.
3. Optional controls are located on the left side of the front panel. You will have to use your scroll bar to reach these.
4. Connect your signals as described below in I/O CONNECTIONS.
5. Run the VI.
>End quote
If you look inside the Diagram of the Count Edges VI you will see a subVI, Group Config CTR, that has a constant set to "simple event counting." This configures the gate in the correct manner. You have 17 or so options to choose from (right-click to see the other choices). Each choice configures the counters as needed. No special effort is needed on your part.
If you really must know more details double-click on the Group Config CTR icon. On the Diagram of that VI is a Call Library function. Right-Click that and see more ugly details that you don't need to know. The functions of the counters are fully implemented by the options already available, so you don't need to know how the details, but it is intersting.
Hints:
Keep in mind that the counters require TTL level signals. 0V to 5V. Limit the current to the level the DAQ board can handle. You will false trip the counter if your low is higher than 0.8V. I have had problems with this when using noisy signals.
Also make sure you debounce any switches you wire to the counters. It is instructive to hook up an unbounced switch to the counter inputs and see just how many false trips they can generate!

Can I use multiple PCI-MIO-16E-1 cards under NT 4.0 SR3, LV 5.1, & NI-DAQ 6.5.1?

We have not been able to run multiple AT-MIO-16E-3 cards with NT 4.0, because (partly) the cards & NT are not PNP. Will changing to the PCI-MIO-16E-1 &/or PCI-6071E (64 channel version) allow us to simultaneously run multiple (same type) MIO cards on the same computer? We want to use one card to interface to SCXI, & it appears that the PCI version uses the same cables/connectors as the AT series.

Hello;
The PCI version of the e-series boards have pretty much the same features of the ISA version, the only difference is the bus.
So, you should be able to use the same acessories as you use with the AT boards.
Anyway, you can still try to install the AT boards with NT. The following link is a good step by step installation guide with some troubleshooting hints also. You just need to select the board and OS you are working at.

Can someone help me set Labview to recognize my AT-MIO-16E-10 board?

I'm running Labview 5.1 on WinNT. I recently had to re-image my PC and have now lost connection to the AT-MIO-16E-10 board. Can anyone show me how to set this up? I cannot remember if an installation CD came with the board. If so where can I get another one?
Thanks for any help out there.

1.) Is it even being picked up by the OS (i.e., does it shown up under Start » Settings » Control Panel » Devices?)
2.) I thought that was a legacy board, which means it should only use Ni-DAQs up to 6.1:

My AT-MIO-16E-2 is acting up lately. I am reading input of ~-6V in all
channels even when the cable to BNC 2090 is disconnected. The V
starts out from 60 and slowly drifts up to -6 V. I ran the diagnostic
online where the device failed the. Could this be the root cause of my
errorneous voltage reading? Is there a solution to this problem?

I am not sure why your digital lines are failing, but they should not affect your analog input lines. You need to make sure that the cable is disconnected from the AT-MIO-16E-2 when you run the test. Also, have you run the Resource Test in MAX, because it can help diagnosis resource problems.
Now for the floating lines. This is actually very common. When nothing is connected to the pins the voltage will charge up on the leads. Sense the pins are not connected to anything and the voltage has no were to go the lines will normally completely saturate the capacitors on the board.
This is not a bad thing and it should not affect your measurements, if you do not scan the channels that are not connected. If you are worried about the unused floating signals, you
can wire the unused inputs to ground.
If you are performing measurements and notice that the inputs are floating you should check your grounding methods. In general use RSE for floating sources, NRSE and DIFF for grounded signal sources. If you want to use NRSE or DIFF on a floating signal you will need to add a 10-100kOhm bias resistor from the negative lead to AIGND to reference the signal. Refer to this KB for more help.

Delphi+At-MIO-16E-10 multithreading, also board identification

Hi Everyone,
I've got two questions to ask....
Has anyone done multithreading using Delphi to control a
nidaq card?
Basically, I want to know if it feasible to
output a function to an analogue output channel using
WFM_op, for example, in one thread, while doing data
acquisition in another thread (using scan_op).
Does anyone know of the limitations here?
Furthermore, since we sometime use multiple cards in the same
computer, if would be useful if we could call a routine to
identify which cards are present (and assigned devicenumbers)
and what board type they are. Note that I don't want to change
the board addresses, just determine which ones are present, and set up
the code depending on
which board the user chooses.
I haven't come across a function that can does these things and I'd
appreciate
any advice.
Regards,
Roland

Upgrade win98/LV4 to win2000/LV6: Speed problems with AT-MIO-16E

I found that in Windows 2000 with Labview 6 the readout rate of our AT-MIO-16E board drops to approx. 2.5 kHz max. (before approx. 11.5 kHz in Windows 98 with Labview 4 ) using the 'AI single scan' VI (see attached scheme for the readout routine). I don't know if this is due to Win2000 or due to the new NI-DAQ drivers, but for our timing-critical application this is unacceptable.
Are there any suggestions about how to accellerate the readout of the AT-MIO-16E board?
With best thanks,
Thomas Schultz

Hi Thomas,
Here is another idea I can give but will be of limited use in chasing it down.
Make sure the board is using DMA.
DMA is alot faster than CPU based data transfers.
Maybe durring the softeware conversion, the board got installed without DMA enabled.
Just an idea.

PWM signal from Accelerometer by using DIO of PIC-MIO-16E-4

I am a new beginner to use digital signal acqusition. The accelrometer send the pulse width modualated signal and I need to use DIO line instead of counter. I wonder how I can measure the pulse width, + duty, and -duty.

Hi Gino,
If you plan to use the digital inputs of the PCI-MIO-16E-4 then you will be limited to software timing since the digital inputs are asynchronous and dependent on software calls. This means your fastest rates are roughly 100-1000Hz (computer dependent). Since you also want to sample a period at least 5 to 10 times so that you can get a somewhat accurate representation of the duty cycle and the pulse width, you are further limited to the signal being slower than 10-200Hz.
However, if this is acceptable then you only need to create a loop and sample your digital inputs at the desired loop speed and perform calculations to determine the duty cycle.
How you would determine the pulse width and duty cycle is everytime you take a digital measureme
nt you also use "Count Ticks (ms).vi" in LabView to count the time between each call to this VI. You simply add these times while the reading is high and you have the high dutycycle. Do the same for low and then add the two together.
Hope that helps.

How to install my AT-MIO-16E-1 in WindowsXp?

I have an board AT-MIO-16E-1 (ISA bus) and I need to use it in a new computer with WindowsXp but I can't find the driver. NI-DAQ 5.0 do not reconize this board. What can I do?

The AT-MIO-16E-1 (6070E) will work in Windows XP. You need to download our latest NI-DAQ driver version 7.3. You can see a list of our DAQ hardware and what version of DAQ is required for particular operating systems at:

AT-MIO-16E-10

I am a student and working with the AT-MIO-16E-10 Board.
Could anyone tell me how can I connect it to a servo motor...
and control it by generate pulse..?

Dear Sven,
Thank you for contacting National Instruments. You shouldn't try to repair or change anything on the board by yourself. If you change any component or try to repair it you loose the warranty; in addition, we can't support your board anymore since we don't know if your modifications changed the physical characteristics of the board.
I suggest you to contact the phone support at 1-800-IEEE-488 (1-800-4333-4888) and send your board for repair.
