labview 8.0 does not recognize MIO

[NewAtLV]

I am doing a home project where I must gather two types of signal (Pressure & LVDT) which must be very accurate. I'm working on the pressure part first.  I bought some spare parts from EBAY but am now having trouble hooking up an Ashcroft pressure transducer (K-15) series to MIO-E (6040e) DAQ card through SCB-68 Terminal block.  I have LV 8.0 (Professional) .  I also have a new Core2Duo XP system.     

My system recognized the DAQ at 1st, but when I rebooted it can't recognize it any longer - even after reinstalling LV several times.  Still, when it recognize the DAQ, it was having trouble finding the DMA channel.  I had hooked up the 4-20mA wires to ACH0 and ACH8 pins on the SCB-68.   I can't get any signals from the terminal block, I don't even know if the DAQ 'sees' the terminal block.  

Yes, I'm a newbie at this and would appreciate any help!!  Am I starting off with the wrong DAQ card to begin with?  I also have a SCC-68 signal conditioner/terminal block.   

 Thanks!

The version of LabVIEW and whether you are using it or not is somewhat irrelevant. First, you need to install a driver for the card. Did you install any driver and if so, which one? There are two types - DAQmx and traditonal DAQ. I would recomend DAQmx. The latest version with support for LabVIEW 8.0 is DAQmx 8.8. Included with the driver is a configuration utility called Measurement & Automation Explorer (MAX).

Yes I did all that.  But I was reading up on DAQMX 8.3 - it does not support MIO-E-4 (6040E) cards any longer.  So I went with DAQ MX 8.1 - the latest version that supports it. 

Anyways, the MAX can't find it.  Can't find device. 

I took out the card.

Reinstalled XP.

Installed Labview

Installed DAQ MX 8.1

Rebooted

Installed the 6040E DAQ.

Rebooted.

Let XP Auto - find the device. 

Can't find it.

Are you using LabVIEW RT (Real-Time)? Support for the PCI-6040E is in the latest version of DAQmx when you are using windows.

In any case, your older version should also work. It does not show up in windows device manager either? Was the DAQ card one of the things you purchased off of Ebay?

The PXI-6040E / PCI-MIO-16E-4 is still supported on Windows and LabVIEW RT. The device that the NI-DAQmx Readme says is not supported in DAQmx 8.3 or later is the NI PCI-7041/6040E, which is a PCI card containing an embedded x86 PC + built-in 6040E, running LabVIEW RT.

NewAtLV, does the device show up in Windows Device Manager? Are there any messages from nipalk or nidevldu in the Windows Event Log?

Ok, now that I know that newer DAQMX supports 6040E, but for LV 8.0, and for my legacy card, isn't DAQ MX 8.1 more than enough?  So you are saying I should use at least DAX MX 8.6?   I did it clean install, again, with the drivers that came with LV 8.0,  it still doesn't recognize the card in MAX.  XP searches for the driver for 2-3 minutes then came up with nothing.  When I goto device manager in windows there is a yellow sign on the device.  It is the only PCI card I installed. 

I also bought LabView 5.1 (also off Ebay) - and did a clean install in my new computer (XP) and it was able to recognize the card as MIO-E-4 but can't get reading from the SCB - 68 (A0, A8) channel.    I have a pressure transducer (4-20ma) wired to it with 15VDC power.   I also have the SCC-68 but can't find it under accessories in MAX. 

I would like to use the higher version but if 5.1 can do the job, (need pressure reading and DC LVDT readings) -  I'll work on the LV 8.0 later as I need it working soon. 

Thanks again..

NewAtLV,

First and foremost I recommend installing the drivers prior to hardware installation. Reference the following NI-DAQ & LabVIEW Version Compatibility (for Windows), for the appropriate version to be installed. Verify that the hardware is supported by checking the driver Read-Me. The SCC-68 won't be selectable until you recognize your DAQ device after which you would be able to configure the connector block in the properties.

If you still can't see the device  in Measurement & Automation Explorer (MAX), check Device Manager to see whether that card is recognized. If that doesn't work, I recommend trying on another PC with the driver installed.

Hi NewAtLV,

This could be very helpful:

When I goto device manager in windows there is a yellow sign on the device.  

If you right-click on the device in Device Manager and select "Properties", the "Device status" box should explain why the device has a yellow sign.
