CHAPTER 4

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.

Figure 4.3. The RMS communications module

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.
