Using Sentinel Dongles

[HoussamAz]

Hello J.C, Thank for your reply. I understood the reason but now, I have many questions if you let me :D 1- I just bought 10 sentinel dongles + 1 Master dongle + 1 Developer dongle, I don't want to use the safenet tools, but Labview only. So, to get this code running perfectly, I should connect the Master Dongle to the PC ? 2- in fact, I want to give the 10 "normal" dongles to 10 Users. Each user should be able to run my labview application once he connect his dongle (same PC). And when he disconnect his dongle, the application stop the data acquisition. So, i should detect any dongle of these, compare some serial ID and start or stop the acquisition depending on that. What should I do ? Please, consider that I'm a newbee with sentinentel software and dongles :/ looking forward to hear from you sir ! regards, Houssam

Hi Houssam,

It's been a while since I last used the Sentinel dongles for a project. Having said that, here goes:

1) Trust me... you'll want to use the Sentinel software to program your dongles. I remember it was a pain in the butt to use the ActiveX COM object to communicate with the dongle via LabVIEW. I can only imagine the higher level of magnitude in complexity it would be to program your dongles using only LabVIEW.

2) Your ideas for using the Master, Developer, and User dongles is pretty much correct.

3) You'll want to program your LabVIEW application, in simplest form, to periodically query for the dongle identification information so as to perform a comparison check. If you choose to go the more complex and secure route, you'll want to program the dongles with various information using the Sentinel software so you can then use LabVIEW to query the particular information you're looking for.

Again, it's been a long time since I've used the Sentinel software, so I am a bit rusty. It's also quite possible that the Sentinel software has changed enough between then and now.

Good luck!

Hi J.C, Thank you a lot. I will try to use the DLL and header files provided by the manufacturer with an example of C code. Have a nice day !
