I'm using the mobile web application for the SMARTDAC+ GX/GP series'advanced security (/AS) model. When I access it from a tablet at http://xx.xx.xx.xx/DRV0/mobile/, a log in is required.

For an advanced security (/AS) model, log in to the mobile web application as the “Monitor” user.
Set up the “Monitor” user on the GX/GP ahead of time.
