.NET Framework 4 Client profile is not supported by our 2008 or earlier controls

Question: I am using Visual C# Express 2010. While trying out program 11.1 Basic Statistics, after referencing the Emant300.dll and EmantCntrl.dll as instructed in the manual, I get the following error:

The referenced assembly "EmantCntrl" could not be resolved because it has a dependency on "System.Design, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" which is not in the currently targeted framework ".NETFramework,Version=v4.0,Profile=Client". Please remove references to assemblies not in the targeted framework or consider retargeting your project.

Waveform Timeout

Question: We bought an Emant380 and Emant300 DAQ, and I am running some tests on them. When using ReadAnalog or ReadAnalogWaveform methods, i noticed a 35 ms delay at each method call with the Emant380, and 15ms delay with the Emant300 (usb). I would like to achieve 100hz frequency, so this delay forces me to use the waveform fonction. That is fine, but if i can get for instance 2000 values at 1000 or 2000 hz, I can't get 2000 values at 100 hz, because the dll throws some serial communication timeout exception (timeout seems to be about 3 sec). Is this timeout the only thing that prevents from getting long duration waveform (for instance 30 seconds at 100 hz which makes 3000 samples)? Is it possible to change this timeout values?

no module named e32socket - Python for S60

Question: I was trying to connect the EMANT 380 with a new laptop. I have paired the laptop and the DAQ. While testing the ReadLight sample code, I am getting an error that says " no module named e32socket". Before that I got no module named Emant. I have copied the lib file with all examples into the Winscw-c-python folder.

Config Analog Advance

Question: I have been using your Emant300 and have gotten it to work properly using VB.net 2005. One issue I have noticed is when trying to use the emant300.ConfigAnalogAdvance it always gives a time out error. I looked in the documentation and haven't been able to find an example of how to properly use it in VB.net.

Would you be able to explain how to properly use this in VB.net so we can change the settings?

Multiplexing Inputs faster than 40Hz

Question: My system have one EMANT300 with 5 strain gauges and I need to capture @ 50hz for each strain gauge. I am using the driver Labview, and change the Positive Input for each sensor. And the parameter "sample rate" to 2500, but the maximum frequency that it is measuring is 12.5hz for each strain gauge. How can I config my EMANT300 to have 50hz for each strain gauge?

Q2: How do I get Single channel 16 bit waveform @ 2500 samples/sec (max)

Follow up question to Q1: If I have 5 strain gauge then 2500/5(strain gauge) => 500/3(delay) = 166 samples/sec for each strain gauge. Is that correct?

Decimation factor and ACLK value for the ConfigAnalogAdvance function

Question: I am using the ConfigAnalogAdvance function to program the EMANT300 module. And then I am using the ReadAnalog to read a voltage between AIN_COM and AIN_AIN2. Both calls are successful and I am getting a reading. The problem is that even when I electrically connect together the AIN2 with AGND I am reading an unstable voltage, where I should read zero (shorted leads).

I assume that with a 24 bit ADC I should get a very stable reading. My voltage sources are a 9 volt battery with some resistors or a short circuit or a LoadCell. All these sources are known to be very stable. I even shorted the input with a capacitor.

I am still getting a fluctuating signal of about 5 % instability. My suspicion is concerning the Decimation factor and the ACLK values.

Wrong Analog Input reading when connected directly to DB25 connector

Question: I have used the simulator to read analog input. I've tested the training kit and it works well too.However, I am unable to read the value of a DC supply (1.5v Battery). The program showed that the voltage level is 2.5v, which is incorrect. A check with the mulitimeter showed that the battery has a potential of only 1.6v. I had connected the positive terminal to pin 11 (AIN0) and negative terminal to pin5 (AINCOM). The rest of the pins are not connected.

Is there any other pins I need to connect?
