Resistor choose in PCI-6527 card

I think I need more help for PCI-6527 card.
Problem 1: In PCI-6527 user manual,page 3-11, last paragraph about the source current. The instrument require digital I/O card can source current 7mA (better10mA) on each pin for activating switch. The switch is TTL(0-1V/3.5-5V)(Which is all information the instrument provided). If I choose the resistor 5K which is recommended in the manual, the source current will be very small(0.3mA) and can not achieved the current for activating switch(10mA). Is my understanding correct or not? If not, how should I choose right resistor value for my current application?
Problem 2 : for current application, I can use the 5V source board since total current on all channels below 1A. Also I can use gro
und line of board to connect to DIG- pin for reference line.Is it right?
Problem 3: Three pins of instrument cable(25 pin sub-D cable) are required to connect to ground line, could I connect these three pins directly to ground line on board or I have to use additional ground lines.
Thanks

Zhou,
Answer 1: The formulas for choosing your resistor are there in page 3-11 and 3-12. Your instrument switch is going to be connected to VOUT (DIG+ and DIG-), you have to check your instrument to see if it requires only the 10 mA current for activating or if it requires 5V or if it requires both. In case it requires only 10mA if you perform the formula V=RI, you are going to find that you need a total resistance of 500 ohms, your board already has a 35ohm resistance so you need to connect a 465 ohm resistance in serial but not as RL, in that case RL is just jumper wire (0 ohm) your 465 resistance is in serial connection with the 35R and all of them make VOUT. Just take a note that your switch may be acting as a relay and it may have a coil on it which adds mo
re resistance, so measure the resistance also of your switch and the sum of 35R + your switch coil resistance + your configurable resistance = 500 ohms, this is in case you need 5V and 10mA in the input of your switch. Check this out because switches may need only to be applied a certain current or a certain voltage but not usually both.
Answer 2: If you are using the 5V source of the board for DIG+ you have to use the ground reference of the board also for DIG-... if you are using an external 5V source, then you need DIG- to connect to the external ground.
Answer 3: We don't know what are this three pins for. Your switch must have a + and - inputs, in which you directly connect DIG+ and DIG-, are these GND pins this - inputs ?... if so then yes. If not, then you should what are this GND pins for in your instrument, if they have other functionality most probably you don't have to connect to the board ground, because you are not getting any source from the board, you are only act
ivating the switches, but I cannot guarantee this because I don't know your instrument.
Hope this is helpful for you Zhou, good luck!...

Line connection between PCI-6527 card and instrument

Sorry for my foolish. My poor electronic knowledge prevent me from fully understanding what you explained in your last reply and need more help.
In fact, we plan to control two instrument switchs, one is for the Magnetic_Suspension_Control(MSC) , another is for control the Weight-changing-Device(WCD).
The instrument manufacturer provide a cable for the MSC and WCD. The cable looks as follows: there is one connection to the computer(25-pin subD-plug) of which two cables lead away, one to the MSC(6-pin Lemosa)and the other to the WCD(15-pin subD-plug).
The interface of the MSC is internally realized by using only two simple optocouples(OC). Their input-pins are connected directly to the 25-pin SubD-plug of
cable as follwing:
25-pol.SubD; meaning
Pin 9 anode of OC1-LED
Pin 7 anode of OC2-LED
Pin 23 cathode of OC-LED
Pin 18 cathode of OC-LED
Because of the optocouplers draw some current from the NI-card, the manufacturer let me make sure that the NI-card can source circa 7mA(better 10mA) on each pin.
The interface of the WCD consists of three simple TTL-level inputs, which are also directly connected to the 25-pin SubD-plug of our cable as following:
25-pol.SubD; meaning
Pin 4 TTL-Input (remote) (0-1V/3.5-5V)
Pin 3 TTL-Input (weight 1) (0-1V/3.5-5V)
Pin 2 TTL-Input (weight 2)(0-1V/3.5-5V)
Pin 5 common ground
The current drawn by the TTL-inputs is not worth mentioning.
By controling the logic state of these above pin states through labview, I then can control the instrument switch.
Based on above information, how should I choose right resistor for achieving the suitable v
oltage and current on each pin and How should I connect line between PCI-6527 card and 25-pin sub-D plug(I plan to use port 3 of PCI-6527 card).
Thanks, your help is greatly appreciately

Zhou,
My best recommendation is that you find someone who can give you a better and more direct advise in electronic circuiting. We don't have in our hands the manual of your instrument in order to clarify what it needs and where, although you gave some pin numbers we cannot take the risk of advising something that we don't have the absolute knowledge of. We can give you all the details you want about our card and what does it gives, but you have to decide how are you going to connect it to your instrument. If you recall your email about the manual, in fig. 3-6 page 3-12 you can see a picture of how to connect a TTL driven device, in the last email we gave you an option of how to connect the resistor and where, please read it again, basically I am going to repeat the same, we feel sorry about not been able to give you more help, but is opt to you to find help in electronic theory. Remember in my last email that I told you the 3 cases in which your instrument may need either voltage, current or both, and I told you how RL will change and what new resistors you may need to connect. Review that and make tests with your switch, your question about how to choose the right resistor is answered in the previous email and how to connect lines between the board and the cable of your instrument you have both pin outs... match them... the person who has in his hands the manual and the instrument is the best person to choose how to interfase both appliances... we are sorry Zhou but if we advise you about pin connections of your device with our blindness we have of your device we may make a mistake, we told you about our pins and how to choose resistors.
If you need more direct assistance on this Zhou you may better try to call us, by text messaging is limited and this requires direct guidance. If you decide to call us you can find instructions at www.ni.com/ask hope you move forward in your application as soon as possible.

Does NI DAQmx driver support PCI 6527 Card

In my application i am using PCI 6527 Isolated DIO Card. In the examples from LabVIEW 7.0, i refered the following VIs
1. Write Dig Chan.vi
2. Write Dig Port.vi
using DAQ 7 Driver.
There it gives a list of devices that can run these examples. The list does not contains PCI 6527.
Can I use DAQmx Example VIs with PCI 6527 Card?
Please suggest me what driver to use with 6527 Card (Traditional DAQ or DAQmx).

Hello partners,
I'm using NI DAQmx 9.7 in a machine hosting a Windows 7, but always when I tried to run the application I got this error.:
CAN'T LOCATE THE DRIVER ERROR 10240
Does you have any idea why could I'm facing this problem ? Previously I was using the original driver NI DAQ 7.4.4 (Legacy) in a machine hosting a Windows XP.
Other point perhaps here isn't the best place to start this new post, but I couldn't find how to post a new topic on the site.. My apologies, i'm waiting for any solution or advice
Best Regards

PCI-6527

In PCI-6527 manual, Chapter 3, page 3-11, third paragraph. I am not sure of what is the meaning "non-isolated power". Is it meaning instrument power or PCI-6527 card power? I plan to use PCI-6527 card to control an instrument switch which is TTL logic (3.5-5V). Does it belong to non-isolated power or isolated power.
Thanks
zhou

Zhou,
If you want to use the 5V source of the board it is not isolated... that means, if you over charge the board with more than 1A you may burn it (fuse). In case you may want more than 1A you can use an external power supply or even if you want an isolated supply. In the manual it means the board power for the non-isolated mode... and for external power supply if you want either an isolated or more than 1A source.
Take a look to the specs of your switch, how much amps does it takes when activating?... common switches uses 100 mA range currents so probably your switch does also... in that case you may use the board 5V source... isolation means protection against... take a look to the picture in that page you mention, there is an optical isolator there, it funct
ions like a relay or like a transistor where the electronic circuitry is going to be "isolated" or protected from the power circuit (external)...
Good luck!...

PCI 6527/PCI 6602 Hardware resource conflicts

Hello,
I'm running into a problem with my motherboard and a comination of NIDAQ cards. Normally I have all 6 PCI slots filled with various cards, I have narrowed the problem down to some combination of 2-3 cards. I can install a PCI-6527 card and a Commtech-Fastcomm ESCC-PCI card into various combinations of PCI slot positions, some combinations the OS will but just fine. Some combinations the OS will come up and show 50%+ cpu utilization in the Idle Process, attribuated to interrupt handling. When a good combination is found I can then install a PCI-6602 card and the utilzation problem shows back up. I have not iterated through all the combinations of the 3 cards yet to see if there is some combination that works, but it appears there is a resource conflict. I have installed NI-DAQ v 7.4T, and have the latest drivers for the Commtech card. I also have one more ESCC-PCI card that needs to be installed, so this may become more nerve wracking. I do not have the ability in the BIOS to manually set PCI assignments. This is on a fresh install of Windows 2000.
Thanks
Message Edited by agchino on 09-02-2005 03:03 PM

If you already have an application that uses the Tradtional NI-DAQ C
API, you would have to rewrite the code that uses the DAQ function
calls, as DAQmx function calls are quite different. I would
definitely recommend using NI-DAQmx for future applications, however.
If things seem normal with just National Instruments boards installed
and the issue arises when you put in the other boards, I would contact
the vendor of your other boards. As far as setting IRQs in
Windows 2000, I believe Windows does it automatically, and ignores what
the BIOS settings for IRQs are. See the following Knowledge Base.
Aside from this it seems that the boards are working -- interrupts are
obviously needed to communicate to devices but as far as what may be
going on at the process level or how the other boards may be affecting
this is more an operating system issue.

Will PCI-CAN card work with only 2 wires?

If I'm using my PCI-CAN card configured for internal power, do I need to connect anything other than CAN-L & CAN-H to my CAN network? I'm doing this right now and am able to correctly receive packets thru the card. However, it appears that my transmitted packets are not being seen by the other nodes. I'll know more when my CANalyzer arrives, but I was wondering if my cabling is OK as-is.

I currently have a connection set up with only CAN-L and CAN-H wires connected. I am able to transmit and receive with no problems at 500kbs, so it should work as long as the lines are properly terminated. (120ohm resistor bridging the wires at both ends)

Connecting a HP3497A with a NI PCI GPIB card.

Hello, I would like to be able to connect the above mentioned HP product with a NI PCI GPIB card. As I have no prior experience with this equipment, I wanted to know what basic important steps I would have to take to achieve this?

Mbugua,
On the hardware end you'll need a GPIB cable to connect the card with your instrument. On the software side, you'll need the NI-488.2 driver. Please follow this link to download the proper driver version for your OS. I highly recommend that you use LabVIEW 7.0 to communicate with the instrument. If you prefer text-based programming LabWindows/CVI 7.0 would be a great choice. You can check out www.ni.com/idnet to download a library of functions to even further ease communication with t
he HP3497A (currently there is a download designed for CVI).
There are a great deal of manuals available online. Please navigate to www.ni.com and choose "support" to search through them as well as our Knowledge Base.
Please follow the following procedure of installation:
1) Install LabVIEW or LabWindows/CVI (or both)
2) Install NI-488.2 (hardware driver for the PCI-GPIB)
3) Insert the PCI-GPIB into your computer

Looking for drivers for an old PCI-FlexMotion card

I'm trying to use an old PCI-FlexMotion card (ASSY nr. 184979B-01) in my win XP PC. The motion software version 5.0 seems not to have a compatible driver because the OS did not found the PIC card. I did not find any addtional driver on NI-support side. Is there any chance to use the PIC card. That old is it not!
thanks.

Nop, it didn't work:
but: I have only MOTION 5.2. (no other older version in available in the NI-Support page) However, I tried with 5.2 copying the files as described in the readme text. The OS does not recognise the FlexMotion board.
Trying choosing the driver manually (PCI device propertiesà update driveràspecific locationà don’t search) in the NI motion controller driver list the Flexmotion board does not appear. I only see: PCI-encoder-4a, PCI Servo-XX, PCI-Step-XXX and some other PXI-7XXX devices. I’ve test some of them with no success.
Thank you.

PCIe Audio Cards for new '09 Mac Pro? (more detailed)

Hi Guys/Gals
I bit the bullet and just upgraded from my Dual 2.7Ghz (LC) G5 to a new 2.66Ghz 8-core MacPro. I now have to find a PCIe audio card (stereo is fine). I used to use an RME Hammerfall 3296 PCI card in my trusty G5 as an alternative audio out (Digi 003R for ProTools and Logic Pro 8 etc.). Do you know of any PCIe audio cards? I just want to use it for iTunes etc as the Digi doesn't allow play through via core audio etc. I already use the optical with my Logitech surrounds but want to send the iTunes stereo signal to my main amp and pro speakers for auditioning cd's and songs.
Thanks in advance!
Bobs

Good point on obsolete! I'm sure there's some new flavour on the way soon too.
Basically, all my firewire ports are used up, I have a Digidesign 003R, 2 FW 800 externals, a FW 400 external HD and an Apple iSight. I tried a Kingston FW hub but got lots of crashes/freezes with it so i can up on that! I may have to resort to either a USB type I/O (lots to choose from there). Someone suggested I use an Airport Express but the problem is that Apple's core audio sends the same signal out the analog audio as it does the optical outs too so I need a completely separate device.
You're right though, I may have to give in on the PCIe card option as most cards are for high end audio and I don't need that. I only need to play stereo tracks from iTunes to my main amplifier.
Thanks again!
Bobs

PCI IDE Cards

I just got a good deal on a 320GB Seagate Barracuda HD. My only limitation is the 128GB limit my Mac sees it as.
After looking here: http://lowendmac.com/macdan/05/1024.html
bI figured a PCI IDE card would be the best choice for my G3. So I could split it into 2 partitions with Panther on the first partition and 9 on the second.
My question is, are the PCI cards plug and play without drivers (like the hard drive) or do I need a "Mac-Specific" card or Mac drivers to use it with my hard drive?

The 128 GB limitation applies to the onboard IDE controller, and not to an ATA-133 controller card that supports 48-bit logical block addressing, which enables recognition of large drives. If connected to an ATA-133 controller card, partitioning the 320 GB drive is your choice, although I prefer to partition larger drives for the ease/speed of routine disk maintenance. The Acard AEC-6280M ATA-133 controller card for Macs is consistently priced lowest here.
Sonnet and SIIG also market Mac controller cards, but whichever brand that you choose to purchase, it must be the Mac version, because the PC versions of these cards aren't compatible. Bootable controller cards must be firmware-based and not driver-based. The card's ROM is read at boot, so that connected drive(s) are functional. If the controller card required a driver to be read from the hard drive, the sequence for doing so couldn't occur, because the hard drive isn't recognized until the controller card (to which it's connected) is recognized.

Setting up PCI-DNET card to work with Eurotherm 2404 Controller w/Device Net

I have installed the NI PCI-DNET card in my PC running W2000 and the NI Measurement and Automation Explorer. I have also wired from the PC Card to a Eurotherm 2404 Controller with a Device Net Module and have terminated the connection with a 120 Ohm termination resistor. The baud rate and address have been configured on both ends to match, however although I am getting a good connection to the board I am not able to pick up the device when I run the "Simple Who" funtion. Any advice would be greatly appreciated.
Thank You

Hi,
When you say “…address have been configured on both ends to match”, do
you mean that you set the ‘Interface MAC ID’ of the dialog that comes
up when you start Simple Who to the one that is used by the Eurotherm
2404 Controller?
Simple Who is a master/scanner in a DeviceNet network, thus the
‘Interface MAC ID’ you configure is the one of the master, which must
not be identical to the one of any slave devices in the network. So,
try setting the ‘Interface MAC ID’ to a value other than the one used
by the Eurotherm 2404 Controller.

Dv6265us connexant PCI sound card + windows 7 = Not working

So I'm here becuase I can't find a driver on my own. I've scoured the internet for hours, finding very little to help with my issue. So here goes...
I have an HP Pavilion dv6000 (Dv6265us), and ever since I installed window 7, Windows cannot figure out what drivers to install for the PCI sound card. The best I've found so far says this:
"Windows found driver software for your device but encountered an error while attempting to install it"
"Microsoft UAA Bus Driver for High Definition Audio"
"If you know the manufacturer of your device, you can visit its website and check the support section for driver software."
Now here's the funky part...everywhere I've found information on my laptop, it says I have a Conexant PCI sound card. If I'm wrong I would love for someone to tell me; better yet, a link to a download to actually be able to use the PCI sound card. Right now the card is under other devices and is listed as "PCI Device".
Now the Link I've provided from the conexant site will tell you this under PC Audio Support - Windows® 7,
"Conexant develops audio solutions that are used in a wide range of products including personal computers. We provide customized audio drivers to our customers, which include major computer manufacturers globally. At the request of these manufacturers, Conexant does not provide end-user support or drivers for PC audio products. If you have an issue with the audio configuration in Windows 7, please contact the manufacturer of your computer.
I tried calling HP support, but they wouldn't even answer my yes or no question... "Do you have audio drivers for my laptop that will allow me to hear sound?" Instead of saying yes or no, I was told that I needed to pay fifty to one-hundred dollars;....fifty dollars for a one time fee of telephone service, or one-hundred for the year. I even went as far as asking..."if you can't fix my problem, do I get a refund?" I was told no...so here I am. I've had problems before with hp...but this is rediculous, and whats worse is from the way things look, Connexant was told NOT to support their own product, or provide drivers for windows 7 by their customer(HP). I realize everyone is hurting for money, but **bleep**, this is a new low...

To answer your question, there are no windows 7 drivers for that model notebook. The notebook was designed for Windows 2000, Windows xp and windows vista.
This is one of the issues with upgrading the OS on a computer before checking the specs of the hardware.
I do understand the frustration but it would be more beneficial to revert back to the original OS that the notebook came with. That is what the HP support desk will have you do to prove functionality of the notebook should you have paid for the Diagnostic Support.
Although I am an HP employee, I am speaking for myself and not for HP. Clicking the "Kudos star" to the left is a great way to say thanks!

Startup gets 'Network cable unplugged' on mini-PCI wireless card

I recently installed a Netgear DG834GT wireless router and now have an intermittent problem connecting my Tecra 9100 to it. If the 9100 has been shutdown for a while (like overnight), when I restart I always get 'Network cable unplugged' for the wireless connection. Rebooting a number of times (anything from 3 upwards) I eventually get connected to the router and all then works fine for hours. Even a quick restart at this point (i.e. once the wireless card has connected) does not cause a problem but as soon as I leave the machine shutdown for a length of time it fails again at reboot.
There are no errors in the Event log.
I am using the built in mini-PCI wireless card and have already upgraded to the latest driver.
Any ideas gratefully recieved, at the moment each morning is a 20-30 minute frustration of rebooting trying to get my connection working.
(Running Win2K Professional)

Checking other boards for help (Netgear etc.) it seems that the 'Network cable unplugged' is a common message when wireless connectivity is failing. However, to prove the point, I have disabled the other LAN card (for which I was also getting 'network cable unplugged' but as expected since it was). I still get the same issue with the wireless card, although now the reboots are slightly more predictable - it normally seems to succeed on the third reboot. I guess disabling the other card has changed the startup timing slightly and in that way made things slightly better.
Again, any other suggestions gratefully received. As this seems to be a timing issue at startup, I am suspicious that one of the other things that runs at that time is causing the problem.

Startup gets 'Network cable unplugged' on mini-PCI wireless card (again)

More info : I have found that this is time related rather than related to the number of reboots. It always fails on the first reboot after being shut down for a period of time. At this point, however long I wait the connection never comes up. However, if I wait a few minutes and then reboot, the second reboot will always successfully establish the connection.
On this basis, the problem has become slightly less annoying as I have a workaround - boot once, wait a few minutes and reboot. That being said, any information on how I can isolate this further (e.g. tracing what is running at startup) would be gratefully recieved.

How to get counter values from pci 6221 card?

Hii
I am using PCI 6221 card .. In that i am using the ctr o .. In my application i am using Linear encoder to measure the Lift movement.. so from software how to access the counter values i.e how much mm it moves...

Measure Angular Position.vi in the LabVIEW examples will be a good starting point. Adapt it to Linear Encoder by clicking on the selector below DAQmx Create Channel.vi.
You can also create a corresponding DAQmx Global Channel (or task) in MAX and then use it in your code.
Feel free to post back if you need further help.
