Settings-> Firmware -> FW Version screen or the remote AUI’s Menu -> System Settings ->
Upgrade Software page. Select the *.tgz file in the Select Upgrade File list (should highlight in

Rack and PM.
2. Using a web browser go to ftp://www3.nautel.com/NX_Series/ to make sure your software version
is the latest available. Check the existing software version . Contact Nautel for the most recent
software revision and download *.tgz file to a laptop or network location.
Transferring Upgrade File
The following steps assume either the laptop will be used to connect directly to the transmitter OR the
transmitter and network computer are currently connected to the same network.
Transmitter IP Configuration
1. Go to the network settings page using the local front panel UI (Main Menu -> User Settings ->
Network Settings)or the remote AUI (Menu -> User Settings -> Network Setup).
2. Record your current network settings (IP Address, Subnet Mask, Default Gateway).
3. If connecting to the transmitter directly with a laptop, you must set a static IP address. Set as
follows:
Disable DHCP: From the remote AUI, press the Static IP radio button. From the front panel UI,
enter the DHCP sub-menu and set to DISABLE.
Set the IP Address: 10.10.10.2
Set the Netmask: 255.255.255.0
4. Set the transmitter for Remote enabled control (i.e., local plus remote).
Laptop IP Setup
The following steps assume the operating system is Windows XP. Adapt as required for computers with
different operating systems.
1. On the laptop go to Start Menu/Control Panel/Network Connections/Local Area Network.
2. In the Local Area Network Status, open the General tab and choose Properties. Scroll down and

Transfer Software Upgrade File to Transmitter
1. If using a laptop, connect the laptop network interface card to J3A of the control/interface PWB
(A4) on the exciter panel using a CAT5 Ethernet cable. Open Internet Explorer and search for
10.10.10.2. The transmitter login screen should appear.
2. If using a network computer, open Internet Explorer and search for the IP address recorded in
Step 2 of “Transmitter IP Configuration” on page 3.3.2. The transmitter login screen should appear.
3. At the transmitter login screen enter:
User: “Nautel” or “****”, where **** is the user assigned user name
Password: leave blank (default) or “****”, where **** is the user assigned password
4. Navigate through the remote AUI to Menu -> System Settings -> Upgrade Software, select the
Manage Files button and press Browse. Locate the software update *.tgz file stored on the
laptop or network computer, and press Upload to load the file into the transmitter upload file list.
Allow this operation to complete.

Installing New Software
1. Set the transmitter to RF Off and for Remote enabled control (i.e., local plus remote). If the
transmitter is already in Remote enabled mode, turn off the transmitter using the remote AUI on
the laptop. Perform the following steps remotely using the AUI on the laptop.
2. Go to the AUI Menu -> System Settings -> Upgrade Software screen and select the update
*.tgz file from the Select Upgrade File list (should highlight in blue) and press Start Upgrade.
3. After a successful load (status is 100% complete and a message indicates a successful load), cycle
the ac power (turn off, then on) on the NX5.
4. This completes the software upgrade. Restore the former network settings on the transmitter and
laptop as required (see Step 2 of “Transmitter IP Configuration” on page 3.3.2).
5. Login and repeat Step 1 of “Preliminary Checks” on page 3.3.2 to determine if the current version is
the same as the upgrade version - this confirms the upgrade was successful.
6. If the upgrade was not successful, repeat Step 1 through Step 5. If still unsuccessful, contact
Nautel.
CAUTION! Do not leave this page until the flash process is complete.
