Make sure that your PC is in the same subnet as the AERO.2000 and connect to the AERO.2000
HTTP server using any browser. To do this enter the AERO.2000’s IP address in the browser
followed by the HTTP server’s port number, 7380.

•

In some browsers you simply enter the address and port of the AERO.2000: For
example: 192.168.1.102:7380.

•

In MS Internet Explorer you must enter: http://192.168.1.102:7380, replacing
192.168.1.102 with your AERO.2000’s IP address.

Right click on the NfRemote link in the HTTP server home page and save NfRemote.exe to your
PC. Locate the exe on your PC and launch the installer and select

The NfRemote version for your AERO.2000 is always available in the HTTP server and can be
accessed as described above.  The same NfRemote version is also on the USB flash drive that
comes, in the box, with each new unit.  The latest version of NfRemote can also be downloaded
from our website.

Every new version of NfRemote is

backward compatible with all previous versions

. The same

NfRemote is used for configuration, control and metering of AERO.10/100/1000/2000 units.
Always update your NfRemote when you update your AERO.2000 software. Below we will
explain how to get started with NfRemote if you have the USB flash drive or you have
downloaded NfRemote.exe from our website.

Once a valid IP address is displayed on the AERO.2000 make sure that your PC is in the same
subnet (but not the same IP address as the AERO.2000). Find the NfRemote.exe on the USB
flash drive or on your PC and drag it to your desktop. Continue with 6.3.
