How can broadcast transmitter operating parameters be monitored?

Davicom’s AM/FM Broadcast Monitor (FMBM) is designed to be used as a receiver for on-site and off-site monitoring of broadcast transmitter characteristics such as Modulation level, RF-Power, Audio presence and frequency drift. Remotely controllable through Davicom’s line of intelligent site monitoring systems, the FMBM can also be manually configured and operated without a Davicom unit.

The Most Complete and Comprehensive Remote Site Management Solution for Broadcast

Broadcast transmitter remote control for AM, FM and TV sites. A Davicom Davicom CORTEX monitors the transmitter and the site around it, and acts locally when the link drops.

How Can Davicom Help You Operate Your Broadcast Station or Network?

Many of the largest public and private broadcast networks in the world use Davicom systems to monitor and control their transmitter sites. This ensures that the listening public has uninterrupted access to broadcast information because site equipment status and performance is continuously monitored.

Davicom remote monitoring systems can be deployed in small as well as in larger networks comprised of hundreds of transmission sites. The units may be networked and connected to a NOC (Network Operation Center) for global monitoring of transmission sites.

On-site equipment can be connected to Davicom units through SNMP, MODBUS or standard GPIO (General Purpose I/O) interfaces, and Davicom units can be reached from outside the site through IP network links, serial data modems or via legacy PSTN (Public Switched Telephone Network) connections.

02 The RTU, defined

What is a Broadcast Remote Management System?

Remote management refers to monitoring, control and operation of electronic or electromechanical equipment located at a remote site from the operator. For larger networks, the operator can be at a central site called the NOC, or Network Operation Center. Remote management applications are almost limitless. At the core of the remote management process is the Remote Telemetry Unit (RTU), a device with communication, measurement and control capabilities.

The RTU is usually installed at each site where monitoring, reporting and control is required. It collects all relevant data from other equipment, analyzes it, performs actions based on specific rules defined by the user and sends alarms to the NOC or to the user.

From managing a remote mountain-top broadcast transmitter, an HVAC system in a building or water pumps in the middle of a city, an RTU finds application almost everywhere.
