Serial Dongle for cRIO LabVIEW RT

We are looking into using an RS232 dongle to plug directly into a cRIO-9014. The dongle needs to have programmable nonvolatile memory. Ideally, communication protocol needs to be straightforward in terms of LabVIEW coding. Since communication will be handled by LabVIEW RT, cannot rely on SDK from the manufacturer (unless manufacturer supplies LabVIEW RT code!)

 

Has anyone completed such a project with success? Can you point me to some manufacturers and options?

 

Thanks!

What are you using the dongle for? If you just want to use it as external memory, you can use a USB thumbdrive, for more info on this look at page 9 of the 9014 Manual.  You can address this memory just like any other HDD from LabVIEW. Let me know if you have more questions about this.

Alright, we're in development right now, and specifications are a moving target. It does NOT need to have non-volatile memory: it only needs to be a dongle that has a hard-coded unique number from the manufacturer. That's it - it only needs to do one thing - return it's unique number. The more binding specifications are that it needs to be rugged, able to withstand at least the atmospheric and vibration specs of the cRIO.

 

We were not going to use the dongle as a datalogging device, where USB definitely is the better choice. Initially, the idea was to have a setup config file stored on the dongle, but now that file will reside on a remote server. Once the cRIO boots up with generic code and reads the serial dongle, it will request the build-specific config file from the server based on the number the dongle returns.

 

Best regards,

Jack

You can accomplish this with either serial or USB.
