NI PCI-MIO-16E-4 ELVIS Legacy Setup

[Jackkc7vlo]

Hi All,

   I've pieced together a low cost Elvis I system, PCI-MIO-16E-4 Daq and cable to help teach my kids electronics.  I've installed NI-DAQmx 9.6, LabView 2012, and Elvis Traditional 3.06.   The Daq is seen the the MAX, and the selftest passes and the calibration runs without error.  When I start the Elvis software, the o-scope works great, but the DMM and Function Generators do not.  The DMM seems to read as if not connected.  The function generator does not appear to be controlled from the Elvis Instruments.   If I put the Function Generator in manual it works fund and even displays great on the Elvis O-Scope.     My understanding is the Oscope using the same resources as the DMM so I am confused as to why it doesn't seem to work.  All the fuses and resistor packs seem to be fine.  I've even verified signals from the prototype board to the connectors and the front panels.

   Is there some other configuration I need to check or change?

BTW, tried this under Win 7 32bit and Win 8 64 bit.  

   Thanks!

Your error with the function generator may be occurring because the oscilloscope and the generator are trying to occupy the same resource.  See the following knowledgebase to find out how to fix this issue:

Also, a common cause for DMMs to not work on older Elvis units would be that you cannot use the function generator and the DMM at the same time.  This could be causing your issue if you are trying to use both at once.  Past that, you might also want to verify that you have everything wired up correctly.  A basic outline for Elvis signal connections can be seen here:

Unfortunately that's not it.  I have tried the DMM alone with the positive side jumpered to the +5V and the - to ground and it seems to just float at 800mv (connected or not).  I saw someone else reported a similar problem and it ended up being a bad cable.   He went through 3 of them before finding a good one.  I have the same cable type.

I guess I need to find someone locallly (Seattle Area) where I can borrow a 68pin cable.   Does anyone know if there have been past issues with the shielded 68pin cables?

Here is KB explaining why your DMM may be getting low readings.  This may not be the case with your application, but is worth taking a look at:

Also, you could potentially check and make sure that you have your program architected correctly.  A basic DMM program can be seen here:

If neither of these provides a fix, what I would suggest doing would be looking for loose connections, and if you can get a hold of a different shielded 68 pin cable you could try that.
