Is there a driver for USB2408 and Labview 2014 14.0 ?

Hi I have installed universal library 6.35. My device shows on instacal, but I cannot find it on LabView. Do you have any suggestions? Many Thanks

Answers
Hello Alex - You say you installed UL 6.35, but be sure you also installed ULx (ver 2.10 is part of the same MCCDAQ CD download). To use MCC brand hardware in LabVIEW, you use our ULx VIs. Many examples are installed on your hard drive, but note that since the USB-2408 can measure both voltage and thermocouples, you need to run the voltage examples, not the temperature examples. Here are two FAQs that should be helpful: http://kb.mccdaq.com/KnowledgebaseArticle50481.aspx and http://kb.mccdaq.com/KnowledgebaseArticle50432.aspx

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

Answers
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.

Cannot create Application EXE

I create my VI using the ULxforLabVIEW, I had no probles creating the VI, and I also create the EXE apparently without error but at the time of running the EXE I get a message saying "the VI is not executable", I already try to fix the problem without success. I notice that at my proyect at the Dependecies field there is a vi called "null" and it has a message saying "Warning: has been deleted, renames or moved on disk", I haven't moved or deleted anything, and I notice that ir appeared after I create the EXE. Do you have a solution to my problem?

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 Frabre - The hardware in itself does not support an analog edge trigger. Therefore, the ULx driver does not support an analog trigger. The USB-202 only supports a digital trigger that can be configured for edge or level sensitivity (rising, falling, high, or low). Please feel free to contact us if you have any additional questions.

Hello - The structure of the data array for our Tin function call is not a perfect match for what LabVIEW is looking for. The TinScan call places the data into one column, verses a row, with a column of data per channel. LabVIEW does not know how to parse this data. However, there are ways to get it to work and display multiple channels. For your convenience, I’m going to email you an example VI to help with your programming. Please check your inbox and let us know if we can help out in any other way.

Answers
Hello Murray - There are three likely causes to the problem you report: 1) You did not run InstaCal (Inscal32.exe) on your target machine, so that the DAQ device was recognized on the target machine. 2) You did not follow the detailed steps listed in the ULx help file for: Building a stand-alone Windows application. The results of which automatically pick up a “browse” file and deploy it on the target PC’s hard drive. The file name follows the following format: ULx_BrowseXXX.LLB where, for example, XXX=110 for LabVIEW ver 11. 3) You have duplicate copies of CBW32.DLL on the target PC’s hard drive.

The message you receive probably means the file was not fully downloaded, or got corrupted during the download. We have not had other recent complaints. But to be sure, I downloaded Version 6.31 myself from this link, and it runs OK. ftp://ftp.mccdaq.com/downloads/MCCDaqCD/ I recommend you download it by saving it to your hard drive first. Then before running it, check the file size. The file size should be exactly 279,810,048 bytes.

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).

The reason the palette menu did not install for you is that most likely you did not actually unzip the beta zip file, before running the MSI (i.e. running the MSI file from within the Zip file will not install any of the files that are outside the MSI file). As for the USB-310x hardware series specifically, yes the range must be set in InstaCal.

Oh yes, the task note. If only that was retrievable from a block palette, because I did not find it in any example. Because the palette menu does not install with ULX for LV13. And I also presume that the card configuration (e.g. 0/10V, -10/10V, 0/20mA for each output of an USB3016) can only be set (and queried) with Instacal, or?

ULx for NI LabVIEW does not offer a way to provide the developer with full information about what DAQ device(s) are connected, or what features the device(s) have. What is supported is: The Create Channel VI presents (to the operator) only channels that exist on the DAQ device(s) that are present in the system. Once a task is created, the Task Node VI from the ULx VI palate can be used to read back the model name & serial number.

It sounds like you cannot install ULx onto LabVIEW 2012 since your CD is too old. You need version 6.25 or higher to obtain ULx 2.02. Download the latest MCCDAQ CD from our website, and update InstaCal, and install ULx 2.02. In this way you do not have to use our Legacy UL for LabVIEW driver which has been frozen for many years and is not recommended for new applications.
