DAQmx Create Multiple Channels

[tumblingari]

I have downloaded the NI Bridge-Continuous Input Program and am trying to modify it slightly to allow for multiple Wheatstone bridges to be connected. Currently, it has the option to connect to a single channel but not to acquire information from multiple channels simultaneously. All of the information in terms of shunt calibration, bridge information, and waveform graph output will remain the same. Ideally, the program will show the largest value in the final waveform graph but it's fine if it shows separate graphs for each of the two inputs. I have been playing around with it without much luck although if I start from scratch and use the DAQ assistant I am able to get the information without trouble. Any help would be much appreciated.

tumblingari,

Since both channels you are reading from are performing the same task with the same parameters, you simply need to specify more than one channel. This link will instruct you on how to do so

[tumblingari]

For some reason the link you had sent doesn't work. Would you mind sending it again?

In terms of your suggestion, that is exactly what I want to do but I am not sure exactly how whether it is simply right clicking and selecting a preferance or if there is something more to it.

Actually you are 99.99% of the way there.

You just need 4 characters

The Name filtering on that control is even properly set to allow multiple selections so just shift click the second channel

For some reason, it still wont let me input two values. I tried using shift select and it wouldn't allow me to select multiple items. I also tried typing it in (cDAQ1Mod1/ai0:ai1) and got an error code 200498 saying the syntax for a range of objects in the input string is invalid. I'm not sure why this is.

When you click on the control, are you selecting 'Browse' or just viewing the default list of single channels?

[tumblingari]

It has 'Browse' on the top and then the other 4 options.

[Dennis_Knutson]

You have to click on browse.

It works!!! Thank you guys so much for all the help. Also, is there an easy way to get it to display the max force (no matter which channel it's coming from) versus having two lines on the waveform?
