Web Based AUI Control
An Ethernet port is available on the LAN connector on the rear panel of the exciter/controller assembly
(see VX3 to VX6 - Program Input Connections on page 1.7.3). This port allows a user with
proper authentication to remotely control and interrogate the VX3 to VX6’s operational status. Most of
the functionality is available on the remote AUI and front panel UI, provided the user has been granted
proper authorization. Refer to the VX Operations and Maintenance Manual for details on setting user
permissions and for a menu tree that shows all functions/features of the AUI and front panel UI.
IMPORTANT! Nautel recommends shielded Cat5e cable, as a minimum, for this connection.
Remote Access
The only access to the remote AUI is through the connector labeled LAN on the rear panel of the exciter/
controller assembly. The customer’s browser must support HTML5 to view the remote AUI.
For security purposes, Nautel recommends you place your transmitter behind a firewall router. To allow
remote AUI access to a transmitter behind a firewall, the firewall must allow TCP traffic through the
following ports:
TCP port 80 for HTTP or TCP port 443 for HTTPS: required to allow the web browser operating
on the remote computer to access the web server operating on the transmitter.
TCP port 7005: Used for RDS/RBDS communication.
TCP ports 161 and 162: Used for Agents and Traps SNMP, respectively.
UDP port 123: Used as the NTP port for time synchronization.
Once your transmitter is isolated behind a firewall, there are a variety of standard network
management techniques that can be used to establish a connection, including routing tables and a
virtual private network (VPN).
Detailed information about network management is beyond the scope of this manual. Selecting a
specific technique often depends on your existing network configuration. Nautel recommends that the
planning, implementation and ongoing support of a network that includes a transmitter be undertaken
by a team that includes at least one member with suitable knowledge of network management.
NOTE:
If you have more than one transmitter on the same LAN, you will need to use port forwarding to
allow access to individual transmitters on the network.
CAUTION!
When connecting to a Nautel transmitter, both HTTP and HTTPS protocols are supported. If
using HTTP, the data traffic is not encrypted, meaning your username/password could be
compromised. For security reasons, Nautel recommends using HTTPS whenever possible.
