CHAPTER 4: RmS REmOTE mONITORING SySTEm
RMS is a real-time monitoring system that connects Meyer
Sound self-powered loudspeakers with a Windows-based
PC at the sound mix position or other location. Optional
RMS software delivers extensive status and system
performance data from every installed loudspeaker. The
MJF-212A monitor is RMS-ready and can be upgraded by
installing an RMS communication board in its user panel.
RMS allows the monitoring of amplifier voltages, limiting
activity, power output, temperature, driver status, warning
alerts, and other key data for up to 62 loudspeakers without
a network repeater. Data is updated 2–5 times per second.
NOTE:
Optional loudspeaker Mute and Solo
functions are helpful for acoustic setup or
troubleshooting. A jumper is installed in the RMS
communication board inside the MJF-212A amplifier
to enable Mute and/or Solo functionality. To use
these features, the software needs to be enabled.
NOTE:
The RMS software allows you to
disable Mute and Solo functions to eliminate
any chance of an operator error (a muting error, for
example). However, these functions can be disabled
permanently by removing the jumper in the RMS
communication board.
NOTE:
RMS does not control AC power.
Loudspeakers are identified on the network by Node
Names assigned during a one-time "commission" into the
RMS database that resides on your computer (as a part
of the software), as shown in Figure 4.1. This information
is permanently retained on each RMS communication
board and in the computer RMS database until you modify
it. Loudspeaker View labels can be modified at any time,
allowing you to customize how you view the data.

Two-way communication between the RMS software and
the MJF-212A monitor makes identifying and matching
loudspeakers and icons easy. Pressing the "service" button
on the MJF-212A loudspeaker's RMS module will help
quickly identify the MJF-212A in the RMS software window;
an icon corresponding to its Node Name will appear on
screen. In addition, clicking on the icon's Wink command
will turn on the LED labeled "Wink" on the MJF-212A's RMS
module. This way any MJF-212A can be easily identified
from the RMS software.

UNDERSTANDING THE RmS mODUlE
When upgraded, the MJF-212A's user panel contains an
RMS communications module, as shown in Figure 4.3.
The RMS communications module
Figure 4.3.
The RMS module has three LEDs and two buttons. Their
functions are described below and on the following page.
NOTE:
The LEDs and buttons on the RMS
communications module shown in Figure
4.3 are used exclusively by RMS, and have no
effect on the acoustical and/or electrical activity of
the MJF-212A monitor — unless Mute or Solo is
enabled at the board and from the RMS software.
Service lED (Red)
The Service LED blinks every two seconds to indicate that
the network hardware is operational, but the loudspeaker is
not installed (commissioned) on the network.
