SNMP Control/Monitoring
SNMP (Simple Network Management Protocol) is a request-response protocol where the client and
agent communicate using binary packets. For Nautel transmitters, SNMP is used to communicate
transmitter control commands (e.g., RF on/off, active preset, power adjustments, etc.) as well as
monitor data such as alarm states and meter values. Nautel supports SNMPv1 and SNMPv2c for VX
transmitters.
Nautel provides the central software component, the SNMP agent, which is a program that runs on the
transmitter. The SNMP agent interacts with SNMP client software applications, which range from simple
MIB browser applications like the free one provided by iReasoning© to customized solutions such as
those provided by Burk©. Nautel does not provide SNMP client software.
Access to SNMP control/monitoring is through the connector labeled LAN on the rear panel of the
exciter/controller assembly. When you log into the remote AUI, you can access the Settings -> SNMP
page to set the SNMP Agent Port number, Read Community and Write Community passwords and
SNMP Trap information.
If you are planning to use SNMP, contact Nautel to obtain MIB files for your client software or are
available through Nautel’s FTP site: ftp://www3.nautel.com/SNMP_MIBs/
Email Server
The transmitter’s remote AUI allows you to configure an email notification feature, which can initiate
emails to specified users when specific alarm or status conditions occur (refer to the VX Operations and
Maintenance Manual for details).
The VX3 to VX6 supports email servers that are both unsecure and secure; requiring authentication
(user name/password) as well as encryption. Consult with your network administrator for more details.
USB
There are three (3) USB ports on the exciter/controller (one on the front panel and two on the rear
panel) which supports USB 2.0. The USB ports can be used to provide a storage media for software
upgrades.
RF Drive Sample
The exciter/controller assembly provides a -44 dB (typical) RF drive sample output, relative to the RF
drive level. This signal is intended for troubleshooting purposes only.
