NxLink
TECHNICAL INSTRUCTION MANUAL
Section 1 OVERVIEW
The NxLink provides remote access to Nautel transmitters over an IP network. A web
browser is required to view status and modify transmitter operation. The NxLink can be used
with a variety of Nautel transmitter systems, including:
J1000 AM transmitters
SC1 system controller units
V series FM transmitters
Vector NDB transmitters
XR series AM transmitters
NxLink is a serial to LAN adapter that uses Nautel developed software to convert the remote
serial protocol of the equipment to information on web pages.
The features of NxLink include:
Remote monitoring and control of Nautel equipment with a web browser
Remote access to alarm and event logs (retrieval of event logs is not available for all
Nautel products; contact Nautel for more detail)
Configurable Email reporting of critical alarms
Ability to Save or Email equipment status for later review
Two browser modes: Normal and single column (suitable for PDAs). To use single
column, simply append ‘\pda’ to the NxLink IP address.
Supports SNMP: NxLink and associated equipment can be controlled and monitored
using SNMP Version 1 management software. Contact Nautel for more information.
The NxLink has an RJ45 connector with two indicators. The speed indicator is lit when
connected to a 100 Mb LAN. The link indicator flashes with LAN activity. Port 0 is used for
device configuration (network parameters). Port 1 is used for equipment communication.
The NxLink software can be easily upgraded over the LAN using an FTP client, or with a
direct serial connection to the device (using a terminal program).

TECHNICAL INSTRUCTION MANUAL
Section 2 INITIAL SETUP AND CONFIGURATION
2.1 INITIAL SETUP
(a) Obtain an IP address, Gateway address, Netmask and DNS Server address from your LAN
administrator.
Some Nautel equipment allows you to configure these settings directly from the GUI. See
the associated transmitter manual for NxLink Configuration instructions. For transmitters that
do not contain an NxLink configuration screen, proceed as follows:
If the network is configured for DHCP, the IP address will be automatically assigned by the
network. To assign a static IP address or retrieve the DHCP assigned IP address, use the
method outlined below.
(b) Using a PC, start up a terminal program such as Hyperterminal. Set the COM settings to:
Bits per second: 115200
Data bits: 8
Parity: None
Stop bits: 1
Flow Control: None
NOTE
For DHCP networks do not press ‘A’ in step (c). After 20 s, the DHCP defined IP address should
appear on the terminal screen and should repeat every 10 s thereafter.
(c) Plug the serial port of the PC into Port 0 of the NxLink using a suitable 9-pin null modem
serial cable of sufficient length.
NOTE
A gender changer may be required given that Port 0 of the NxLink is male.
Ensure the NxLink is connected to the LAN via its RJ45 connector and a Cat5e cable of
sufficient length. Apply power (between 7 and 30 V dc) to the NxLink using the transmitter
supplied connector or an ac-dc adapter. For DHCP networks, see the NOTE after step (b).
To proceed with assigning a static IP address, from the PC terminal program, press ‘A’ when
the message “Waiting 10 seconds to start ‘A’ to abort” appears. A message similar to the
following should appear:
Netburner MCF5441x Alternate Image Monitor Vx.x date time
HELP for help
nb>

Page 2-2 NxLink Technical Instruction Manual
Issue 2.0 Section 2 Configuration
Type “setup” at the nb> prompt. The setup menu should appear. Type “7” and press
Enter. When the message “Wait?” appears, type “10” and press Enter. Ensure the
following settings are displayed:
IP Address: 0.0.0.0
IP Mask: 255.255.255.0
IP Gateway: 0.0.0.0
Wait: 10
DNS Server: 0.0.0.0
Enter “1” to set the IP Address.
Enter “2” to set the IP Mask.
Enter “3” to set the IP Gateway.
Enter “A” to set the DNS server address.
Enter “S” to save.
Enter “X” to exit.
(d) Connect the PC to the LAN, ensuring that the IP address and mask are appropriate.
(e) Open a web browser and enter the URL of the NxLink. For example, if the IP address
was 123.456.7.89 then use http://123.456.7.89 for the NxLink address in the browser. To
use single column, simply append ‘\pda’ to the NxLink IP address.
(f) Verify that the page in Figure 2-1 appears. Proceed to Section 2.2, Configuration.

NxLink Technical Instruction Manual Page 2-3
Section 2 Configuration Issue 2.0
2.2 CONFIGURATION
(a) Click on the Login link and use a username/password that provides full control of the
NxLink. If this is the first time that the NxLink is being configured, use the default
username/ password of “root/nautel”. This account has full permissions and can be used
for initial setup.
NOTE
For security purposes, Nautel strongly recommends you change your password (see Section
2.4 - Users Link).
(b) Once logged in (see Figure 2-2), the left-hand side of the screen will change to show
administrative links. Click on the Site Configuration link to select and set up the
connected equipment (see Section 2.3.1), and to set up the outgoing email parameters
(see Section 2.3.2). Click on the User Administration link to add users and to modify

2.3 SETUP LINK
2.3.1 Connected Equipment Settings
All equipment which is to be controlled and monitored by the NxLink must be set up in this
dialog. The primary device MUST be the transmitter or system controller that the NxLink is
serially connected to. Devices further down in the equipment hierarchy are selected as sub-
devices. The dropdown box shows all supported equipment.
The supported equipment is listed by common name (e.g., V5) and Nautel type
(e.g., NARF45). There can be several versions of supported equipment, as indicated with
unique type; therefore, it is important that the correct type be selected. You can check the
equipment label (on the back) for equipment type or contact Nautel if you cannot identify your
equipment.
Each piece of equipment that is added is assigned a tab in the navigation bar and a hyperlink
under Equipment on the left side of the page. The device tabs will appear in the same order
as they appear in the sub-device list. Clicking on the device’s assigned tab will allow it to be
configured using the dialog illustrated in Figure 2-3.
NOTE
In a combined system with two V10s, the primary device would be an SC1 System Controller
and each V10 would be listed as sub-devices.
Enter the Status Refresh Interval (between 5 and 255 seconds). This setting determines how
often the NxLink updates the Status pages. Ensure that connection speeds are sufficient for
the desired refresh rate.
Figure 2-3: Device Setup Page

TAB

NxLink Technical Instruction Manual Page 2-5
Section 2 Configuration Issue 2.0
Enter the Serial Timeout Interval (between 0.1 and 10 seconds). This setting determines the
time duration that the NxLink will wait for a response from the transmitter after the NxLink
sends a request. If the NxLink is directly connected to the transmitter using a serial cable, do
not modify the Serial Timeout Interval setting from the default value. If the NxLink is
connected to the transmitter using a high latency link (e.g., wireless GSM modem), modify
the Serial Timeout Interval setting as required for link latency.
There are eight configurable information pages available for each device (scroll down to see
all pages), and each page can contain up to 16 channels of equipment data.
Selecting the Customize link on any page in the list allows modification of the channel data,
as shown in Figures 2-4 and 2-5.
Selecting the device hyperlink under Equipment displays this information in a page-by-page
format using selectable tabs (e.g., System Summary, Presets, Meters, etc.).
Figure 2-4: Setup Equipment Page - Configure
Each page of equipment data can be named, and any available equipment data can be
assigned to any channel. There are factory default page names (e.g., System Summary,
Presets, Meters, Alarms, etc.), that are linked to tabs, and channel names (e.g., RF Power,
System Control, Active Faults).

Page 2-6 NxLink Technical Instruction Manual
Issue 2.0 Section 2 Configuration
Choose the drop-down box on any channel to see the list of available equipment data. Some
data are complex (indicated in bold text) in that they can be selected as a single type but will
show as multiple data. An example is Active Faults, which will show all faults.
Click Submit (bottom of screen) to save changes or click Reset (bottom of screen) to restore
previously saved settings.

Section 2 Configuration Issue 2.0
2.3.2 Email Configuration
The dialog in Figure 2-6 is accessed by selecting the Email Server tab at the top of the page.
Use it to set up the outgoing email parameters. To use the feature (discussed later) of the
NxLink, whereby it can send emails when events occur in the equipment, the email server
must be configured. Enter the server name and an email address (which will appear in emails
from the NxLink as the sender). If the email server requires login, check the Login Required
box and enter a username and password to the email server.
Consider the following when entering the Email Server fields:
SMTP Server can be an IP address; email server port defaults to port 25
Return Address should be the email address used in the ‘From’ line of the email
received. Note that some anti-spam software operating in mail servers may reject
attempts to use a Return Address that does not match the Mail Server Username.
Mail Server Username depends on the requirements of the mail server, but in many
cases, it is an email address. Consult your mail server software’s documentation or
with your IT manager. This field has a 20-character limit.
Gmail email is no longer compatible with the NxLink. Gmail now requires TLS 1.2
which is not present on the NxLink.

2.4 USERS LINK
Selecting the User Administration link will bring up a page that displays, as a minimum, the
registered users. Depending on permissions assigned to the logged-on user, other
information may be presented. As shown in Figure 2-7, the logged in user is ‘root’, who has
full permissions. As a result, this user is allowed to add new users. Adding a new user
requires entering username, password, and permissions.
There are four levels of permissions, each with their own specific function: User
Administration, Site Configuration, Equipment Control and none. They can be selected in any
combination. If none are selected, no permission is granted. Any user, regardless of
permission level, can change their own password and email parameters.
User Administration: Only level that can add, remove, and modify other users. No
site configuration or equipment control functions.
Site Configuration: Allowed to do all Setup link functions (see 2.3). No administrative
or equipment control functions.
Equipment Control: Equipment can be monitored and controlled. No administrative
or site configuration functions.
None (no permission boxes checked): Only allowed to monitor equipment data.
NOTE
To perform software upgrades (see section 4), a user must have both User Administration
and Site Configuration permissions checked.
With User Administration permissions, all registered users will show as an active hyperlink.
Any other permission level will only show the logged in user as an active hyperlink. Clicking
on a user hyperlink allows user configuration to be modified as shown in Figure 2-8 and 2-9.
