Hi Tony and welcome to Digi Forum.
If yours is a brand new unit, it should have a unique passowrd on the label, so you would need to use that one to login. As username, it depends on the firmware, but most probably you would need to use "admin".
See pag. 2 of latest release notes for any further detail: https://ftp1.digi.com/support/firmware/transport/ftp/latest/93000812_AG.pdf
If you still have issues, please send an email to firstname.lastname@example.org with all details so we can further assist.
