Error while connection the DAQ navi with USB-4761

Hello LabVIEW users, 


I am new with DAQ navi assistant. My goal is to control the 12V DC relay through usb-4761. The usb driver has been installed successfully and I have tested the usb-4761; using Advantech navigator and it works fine. 


I have successfully setup the DAQ navi assistant in a while loop in order to switch on three outputs of usb-4761.(Refer to attached file for screenshot) However, after clicking the 'Run' button, Its shows an error "error- 536870891 occurred at'

possible reasons: The required device does not exist. "


Can anyone please share how I can tackle this problem.

Hi Singh_Chahal,


This problem seems related to the installation of the driver. Follow the 2 documents below for reference:


Also, as this device is from Avantech from what I understand, you could post on their forums as they might have more experience with this.

Hi PedroR, 

Thanks for sharing these links! The system used is in the campus so some permissions were required. 


Thanks though!
