sc 2345 and PCI 6259 problem

[ys61]

Hi

I am  newby programmer in NI. I have  PCI 6259 data acquisition card with SC 2345 signal conditioning card. But I have two problem. First problem is I appplied  one analog test signal from AI07 (amplitude of this input signal between-30m and 30m). I set up every driver and program acording to manuals and  when I worked MAX (measurent and Automation Explorer) I can see PCI 6259, SC 2345 and SCC AI07 below the section of "NI-DAQmx Devices" .Then I want to see my analog test signal and directly clicked the AI07 and after that I clicked Test panels. Choosing the channel name and other configuations I can see the analog test signal correctly.

on the other hand,  I clicked the PCI 6259 and test panels after that I choiced the  channel name as "Dev1/ai0...ai16" I couldnt see anything. My question is how I can see this input signal from the channels of 6259?

My second question is I also tried to see this signal in Mtlab.So I wrote a matlab program and I defined analoginput and channels like this

ai = analoginput('nidaq','Dev1');

channel=addchannel(ai,0:5,'SCC1');

but I also didnt see any test signal. All of the signals were  like MAX  for PCI 6259. So I changed the analog input  device ID as

ai = analoginput('nidaq','SCC1');

but this time matlab gave an error that

"This device is not recognized by the toolbox.   However, many times, support
for new hardware can be added.   Visit The Mathworks web site and search on the
name of your device for more information."

Any solution for these problems will be appreciated

Hello Yusuf,

Welcome to the NI Discussion Forums.  Although your SCC signal conditioning system is leveraging your PCI-6259 M Series device to perform analog to digital conversion, for the NI-DAQmx driver to properly scale and represent your signals, you will want to reference your SCC module directly rather than referencing your DAQ device in all device and channel strings.  After configuring your SCC system in Measurement & Automation Explorer (MAX), which it sounds like you've done correctly, the SCC-AI07 module will be given a unique device name, such as "SCC1Mod2".  This is the device name you will want to reference in your program.  The SCC-AI07 module has two analog input channels, so the full physical channel name would be "SCC1Mod2/ai0".  The easiest way to double check this is to see what channel names are listed in the Channel Name drop down box when you open up a Test Panel for that specific module.  I don't really have any experience with using these devices in Matlab, but I would recommend double-checking your device and channel strings to make sure they match what I've described above.  I hope this helps,
