Input/ Output channel pin on connector CB-68LPR

[Kelvin 403]

Hi !

My name is Ng Chee Kong, I have a PCI-6035E device board installed in my PC with CB-68LPR connector ( see attach CB-68LPR.doc ).

I'm trying to use OpAmpTester2.vi ( see attach ) to measure an operational amplifier chip. Can I known which 'J' pin on CB-68LPR connector represent
the I/O Devices - channels ( Out channel "0" and In channel "1" ) in OpAmpTester2.vi and also the ground point on CB-68LPR connector.
Thank you !

Regards,

Ng Chee Kong,

The pins map 1-to-1. For example, pin "J10" on the CB-68LPR corresponds to pin 10 on the 68-pin connector of your DAQ board. For a complete pinout of the 68 pins on your DAQ board, please see the User Manual for your board at http://www.ni.com/manuals.

Some additional information on my question.
For example, Out Device �1�, Out channel �0� is it
refer to pin J68 (ACH0) of CB-68LPR and

In Device �1�, Out channel �1� is it
refer to pin J33 (ACH1) of CB-68LPR and pin

J67, J32, J64, J29, J27, J59, J24 and J56 (AIGND) are
the ground points. I can use any of them as reference to ground.

If I need to do measurement on an operational amplifier.
Do I just need to connect J68 to the input side of OpAMP and connect J33 to measurement the output of OpAMP.
Sorry very new to labVIEW

Kelvin,

Actually ACH refers to the analog input channels of your DAQ board. If you look at Figure 4-1: I/O Connector Pin Assignment for the NI 6034E/6035E/6036E in the PCI-6035 User Manual you will find that there are two output channels, DAQ0OUT and DAQ1OUT. There are 16 single ended analog input channels labeled ACH0 through ACH15.

If you are wanting to use the analog output channels you will have to use DAQ0OUT or DAQ1OUT along with one of the two AOGND channels (not AIGND, which are for analog input). For your hardware, DAQ0OUT is pin 22 (J22) and DAQ1OUT is pin 21 (J21). The two AOGND channels are pins 54 and 55 (J54 and J55).

Thank you ! Will try it on my lab next friday (270603)

Have a nice weekend 🙂

Hi !

How can I check the configuration of the DAQ device which input mode (NRSE, RSE and DIFF) is it configured ?

Thank you !

[JustinBritten]

Kelvin,

To change the input mode you will have to launch the Measurement & Automation Explorer (MAX). Open the Devices and Interfaces folder in MAX and find your DAQ card. Right-click on the card and choose Properties. From the properties page you can configure the input mode of the card.

Hi !

Is there any manual I can refer to for the configuration of DAQ device.

[JustinBritten]

Kelvin,

We have one of the best support web sites available. The answers to most all of your questions are available online and can be easily found by going to www.ni.com and using the search feature.

All of our manuals are available at http://www.ni.com/manuals. The best starting point would be the User Manual for your particular DAQ device. You could also refer to the DAQ Quick Start Guide or even the Help available from the Help pull-down menu in MAX. There are also installation guides available by clicking on the main support link from our homepage. On this support page you will find a link to "Installation and Getting Started".

These are all excellent resources and I'm confident
they will be able to guide you through the installation process.

Regards,
Justin

Hi !
The DAQ board I used for measurement of my operational Amp (741) is PCI-6035.

I have a power supply with +/- voltage supply and a ground point. I have connected the non-inverting input of the operational Amp (741) to the ground provided by the power supply.
The DAQ0OUT is connected to the inverting input of the operational Amp (741) and ACH1 to the output of the operational Amp (741).
AIGND, AOGND and AISENSE is not connected to the operational Amp (741).
The DAQ device is set to NRSE input mode. I can get some waveform but not a correct one.
I think I have some problem on connecting the ground reference for both in/output.
