Can I access a tank located on another computer?

In OpenEx, how do I make histograms with reference to a certain event?

I'm getting a microcode version error in OpenWorkbench. Does this mean my project will not run properly?

I need to export data to the PLX format to be used in Offline Sorter and Wave Tracker. But whenever I try to do that in OpenBrowser, it crashes. What am I doing wrong?

Why do all zeros get loaded to the target buffer when using OpenDeveloper commands “WriteTargetV” and “WriteTarget”?


Question: Can I access a tank located on another computer?

Answer:  You should be able to access a tank on another computer (PC1) so long as the tank is registered on PC1 and the folder that contains the tank files is accessible from the computer(PC2) you are using. That means PC1 and PC2 must be on the same network. You should also ensure that the folder that contains the tank files is shared.

Question: In OpenEx, how do I make histograms with reference to a certain event?

Answer:  In order to build histograms or rasters, you need to have an epoch as a time reference. Epoch events are scalars associated with the tank’s time line. You can select a time reference epoch in the plot's properties dialog box.

Question: I'm getting a microcode version error in OpenWorkbench. Does this mean my project will not run properly?

Answer: Not necessarily. The version error in OpenWorkbench is a reminder that you should update the microcode on your devices when you update the TDT drivers and RPvds. You should still be able to run an existing project as long as you don't make any modifications that utilize components added in RPvds version 5.0. However, we recommend updating your microcode as soon as possible. For instructions on updating microcode, see your RPx or TDT help.

Question: I need to export data to the PLX format to be used in Offline Sorter and Wave Tracker. But whenever I try to do that in OpenBrowser, it crashes. What am I doing wrong?

Answer: Usually when Browser crashes while trying to export to the PLX format, it may be a problem with either the version of Browser or with the Scaling Factor being used in the export configuration. First, make sure you are using Browser version 1.54 or above, then read about the scaling factor calculation in the latest version of OpenEx Help. Usually, the crash is because the scaling factor you used was too large.

Question: Why do all zeros get loaded to the target buffer when using OpenDeveloper commands “WriteTargetV” and “WriteTarget”?

Answer: Unlike ActiveX commands that allow you to specify the data type to be loaded, the OpenDeveloper methods WriteTargetV and WriteTarget expect any data to be converted to type “single”. In MATLAB, convert your data using the "single" command.
