Andre, I'm having this problem when in Fieldpoint Explorer. After configuring the 1601 and attched I/Os, an option to grant / restrict IP access to the 1601 available under "network security". Clicking on this button opens another window offering the IP security settings. Upon finishing these settings, you must save them. This is the point where you are asked for a password. I have tried an empty and the admin password we use for Lookout, but as you can guess, no luck. The documentation also indicates the need for a password, but does not indicate a default password or how to establish one. Again, any help would be great. Thanks, Mark
