CHAPTER 3: RMS REMOTE MONITORING SYSTEM

The M2D and M2D-Sub loudspeakers are fitted standard with an RMS communication module installed in the rear of the loudspeaker. The RMS real-time networked monitoring system connects Meyer Sound self-powered loudspeakers with a Windows-based PC at the sound mix position or other remote location. Optional RMS software delivers extensive status and system performance data directly to you from every installed loudspeaker.

RMS allows you to monitor amplifier voltages, limiting activity, power output, temperature, fan and driver status, warning alerts, and other key data; data is updated two to five times per second.

NOTE: Optional Speaker Mute and Solo functions, helpful for acoustic setup or

troubleshooting, are also available. An internal jumper must be installed in the RMS communication module in order to enable Mute and/or Solo functionality; the software also needs to be enabled for these functions.

The M2D and M2D-Sub loudspeakers are shipped with these functions disabled. Once enabled, the jumper(s) can still be removed to eliminate any chance of an operator error (a muting error, for example) during a performance, and both functions can be controlled by software commands in any case. Also note that RMS does not control loudspeaker volume or AC power.

Loudspeakers are identified on the network by Node Names assigned during a one-time “commission” (Figure 3.1) into the RMS database that resides on your computer (as a part of the software).

This information is permanently retained on each RMS communication module and in the RMS database unless you modify it. Speaker Titles can be modified at any time, allowing you to customize how you view the data. In addition, any M2D or M2D-Sub loudspeaker can be physically identified from RMS software by activating the Wink function – a Wink LED will illuminate the RMS communication module that corresponds to its Node Name.

M2D and M2D-Sub loudspeakers are identified using the RMS software by activating the “service” function; an icon will show up on the RMS screen corresponding to its Node Name (Figure 3.2). This makes verifying Speaker Titles and speaker field labels easy, using the Wink or Service Button commands.

UNDERSTANDING THE RMS USER PANEL

The RMS section of the user panel has three LEDs and two buttons (Figure 3.3).

Figure 3.3. RMS section of the user panel

The following sections describe their functions.

Service LED (Red)

When blinking once every two seconds, the Service LED indicates that the network hardware is operational, but the loudspeaker is not installed (commissioned) on the network. When a loudspeaker has been installed on the network the Service LED will be unlit and the Activity LED will flash continuously.

NOTE: When continuously lit, the Service LED indicates that the loudspeaker has had

a local RMS hardware failure. In this case, the RMS communication module may be damaged and you should contact Meyer Sound Technical support.
