RMS : Remote Monitoring System
The RMS remote monitoring system is a real-time monitoring system that connects Meyer Sound self-powered speakers with a Microsoft Windows-based computer at the sound mix position or other location. RMS software delivers extensive status and system performance data directly to the operator from every installed speaker. RMS displays include amplifier voltages, limiting activity, power output, temperature, fan and driver status, warning alerts, and other key data for up to 62 speakers at a display update rate of 2-5 times per second (see page 4 for a list of all monitored parameters). More data is available, and with greater convenience, than from conventional monitor systems. The RMS Monitor Program interface is quickly learned, and runs in a Windows environment. Supervision of a sound system becomes effortless. Monitor Displays Each speaker appears on the computer’s color monitor as a “View”, in the form of a status Icon, Bar Graph Meter, or Text Meter (numerical values) depending on user preference. Each View contains speaker identification information and data from the amplifier, controller, driver, and power supply of that particular unit. System status conditions cause color changes in Icon and Bar Graph indicators, alerting the operator to faults or excessive levels. The Views are moveable, and typically are arranged on the screen to reflect the physical layout of the loudspeakers. A user can design a screen “Panel” of Icons or Meters and save it on the computer’s hard disk, conveniently named for a unique arrangement or performer. If the speaker installation pattern changes completely, a new screen Panel can be built. If a different subset of already installed speakers is to be used at the next show, only selected speakers need appear on the monitoring screen for that performance. Functions A Panel of Icons is a status monitoring tool to flag conditions possibly warranting attention. A quick visual scan of the monitor screen is sufficient to be fully informed of the operational behavior of large numbers of speakers. Mouse-clicking on an Icon adds a Bar Graph View for that speaker. Clicking on the Bar Graph adds a Text Meter. In this way during a performance the operator may investigate unusual behavior in increasing detail, making adjustments as necessary. Added Meters can then be closed, allowing return to the normal monitoring Panel. Control Functions Speaker Mute and Solo commands for acoustic set-up or troubleshooting are available on the Icon and Text Views. These functions are optional. A jumper must be installed in the amplifier module of a speaker in order for it to Mute or Solo. If desired, the jumper can be left out to eliminate any conceivable operator muting error during a performance. These functions can also be disabled by software commands. RMS does not control speaker volume or AC power. ID Functions Speakers are identified on the network by Node Names assigned during one-time “Logical Installation” into the RMS database. This information is permanently retained at each speaker Network Board and in the computer RMS Database unless modified by the user. Speaker View titles are modified by the user at any time. View titles and speaker field labels can be verified using the Wink or Service Button commands. Network Hardware RMS uses an established network platform developed by Echelon Corp., the world’s leading supplier of networking technology for monitoring and control. The robust platform is not affected by loss of power at a speaker node, does not require coaxial or fiber optic lines, is polarity insensitive, and supports Free Topology (flexible wiring configuration). The RMS network is a realtime data acquisition system (no data is lost). Each speaker samples and holds all data until it is transmitted. Displays are updated 2-5 times a second depending on the View format selected. A standard RMS network allows up to 62 nodes (selfpowered speakers). The network length is defined as the sum of all the interconnecting wire lengths. If using Free Topology, the maximum network length is 1640 ft. The maximum line length can be increased by using heavier cable and exclusively Bus Topology, or by employing network repeaters. Higher capacity, longer networks are configured with additional hardware. Contact the factory for further information.
Installation Interconnection of the network computer and speakers is straightforward, using twistedpair cable and simple connectors. The network plugs in to the connectors on the Network Board located at the rear of the computer, and on the User Panel at the rear of each speaker.
