Web Based AUI Control
An Ethernet port is available on the LAN connector on the rear panel of the transmitter (see Figure
1.7.1: on page 1.7.5 ). This port allows a user with proper authentication to remotely control and
interrogate the VX series transmitter’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 available functions/features of the AUI and front panel UI.
IMPORTANT! Nautel insists you use shielded Cat5 cable or better to make this connection
.
Remote Access
The only access to the remote AUI is through the LAN connector on the rear panel of the transmitter.
For security purposes, Nautel recommends you place your transmitter behind a router acting as a
firewall. To allow remote AUI access to a transmitter behind a firewall, the firewall must allow TCP
traffic through the following ports:
 TCP port 80: 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.
