Hello Emmanuel - MCC’s hardware does not support reading back values written to the output. If the error code (returned from the data write) is 0, then the output was successful.

I think you are talking about using the digital outputs (8 on FirstPortA and 8 on FirstPortB) on the USB-1208LS, which is an older hardware model (that uses a real 8255 IC; newer models emulate the 8255). The issue you report is limited to just a couple of older DAQ models. A workaround is to, at the start of your app, write out benign values to both FirstPortA and FirstPortB, before you start to write new values to either port. Any further writes will not impact (reset) values written prior, since the direction of both ports were set (automatically for you by ULx) in the first two writes.

Most analog output examples that get installed with ULx demonstrate hardware paced/clocked mode. But if you only want to send out an occasional D/A value, which the DAQ device will hold until you update it at some later time, then software paced mode is more appropriate. We have posted such an example at the link below: http://kb.mccdaq.com/KnowledgebaseArticle50451.aspx

NI for LabVIEW sampling rate

Hello, I am using NI for LabVIEW and have a basic analog input set up to acquire data from an OMB-DAQ-2416-4AO. I set it up using the "Using NI LabVIEW with Measurement Computing DAQ" video. If I set the sampling rate so that the data is collected in under about 10 seconds, there is no error. If I set the rate and # of samples such that it takes longer to complete the acquisition, I get a 10003 error. There must be some sort of control that is looking for the data to be complete within a certain timeframe; is this adjustable? If so how? Thank you very much.

Error 10003 usually means that the timeout has been reached. You set the timeout via the ULx Read VI. The default is 10 seconds, which matches what you report. So instead of leaving the timeout pin unwired (as shown in the video), wire up a constant of something > 10.

No physical channels when AI Temperature (analog) is chosen

I'm trying to get a temperature input, not a voltage input, in LabVIEW. However, no physical channels are shown when trying to create them. The physical channels are only shown for every other input/output except AI Temperature. I've tried high and low to find a solution to this problem. I hope someone can assist me with this.

Answers
It sounds like you want to perform Analog Input, but you are presented only with Analog Output channels, or vice-versa. The USB-1208FS DAQ model you are using has both types of channels (though you should select AI Voltage, not AI Current input, since the USB-1208FS only measures voltage. What likely happened is that you changed the Create Channel VI’s channel type, from Analog Output to Analog Input, but you did so after wiring in a channel selector. Try deleting the physical channel selector (purple) to the left of the Create Channel VI, and then recreating it. It should then locate the proper channels. Otherwise, try our function-specific examples that get installed as part of ULx.

In Labview, using ULx Virtual Channel, the physical channel does not show up!

Hello there, I have Labview (13). I install the latest version of MCC DAQ (V 6.35). I Installed USB-TC correctly. I configure the board using Instacal. It can be seen from TracerDAQ and InstaCal. It seems that computer recognizes the board (USB-TC) very well. However, I have problem with Labview at first step. Developing a new VI, I put the first icon as "ULx Creat Virtual Channel". The second step, creating a channel, I used constant "physical channel" and browsed through the list. There is no sign of any channels or port in the list. To sum up, Labview cannot see any USB-TC channels. Please help me to resolve the problem Many thanks

Most likely what happened is that you created the constant (or control) for the “physical channels” input before setting the Polymorphic VI Selector to “AI Temperature”. The default is “AI Voltage”, and since the USB-TC does not measure voltage, no channels would be shown in the list.

Answers
MCC’s ULx for LabVIEW includes an example named ULx Acq Temperature Sample.vi which works fine with the USB-TC, but it only samples just one reading on only a single channel. Common needs are to expand the number of channels and to sample continuously. The USB-TC is only software paced, so a software timed loop is needed. You can configure the Create Channel VI to specify a range of channels, and then the Read VI can output a one-dimensional array … one sample per channel. At the link below is such an example, that samples 5 channels at a 1 Hz rate. It does not graph the data, or log to disk, but you can use LabVIEW’s built in VIs to achieve those. http://kb.mccdaq.com/KnowledgebaseArticle50417.aspx

Answers
Hello Swank - If the LabVIEW version you just installed happens to be version 2013, be sure to install the very latest ULx (2.03), otherwise ULx won’t be installed for that LabVIEW installation. Normally a copy of ULx is installed for each and every LabVIEW on the PC, from 8.5 upward. Therefore you don’t need to move ULx VIs from one version of LabVIEW to another. Also note that the ULx VIs installed were all saved in 8.5 format, so you will get warnings when you open them in a newer version of LabVIEW. Either ignore the warnings, or re-save all upon exiting. BSODs are not at all common, and may be a sign that something is corrupt (best to uninstall and reinstall).
