CHAPTER 2: INSTALLING AND CONFIGURING RMSERVER
ABOUT RMSERVER
RMServer is the central hardware component of a Compass
RMS remote monitoring system. RMServer is a compact
server that connects up to 50 RMS-equipped loudspeakers
or 12 MPS-488HP power supplies to a computer running
Compass control software. (Each MPS-488HP can drive up
to eight loudspeakers for a total of 96 loudspeakers on a
single RMServer.)
RMSERVER FEATURES AND FUNCTIONS
RMServer Front Panel
Figure 1: The RMServer front panel
The RMServer front panel contains a Reset button and a
number of indicators.
Reset button: Pressing the Reset button restarts RMServer.
There are several reset modes invoked by different kinds of
button presses. For more information on restarting
RMServer, see the section"Restarting RMServer" on
page 18.
Fault indicator: Indicates loudspeaker faults and abnormal
operating conditions. The Fault indicator is also used to
show when RMServer is running in failsafe mode. For more
information on when to use failsafe mode see the section
"RMServer Failsafe (Recovery) Mode" on page 18.
RMS TP/FT10 Receive LED: Indicates that RMServer is
receiving messages from a device.
Client Connect LED: Indicates that RMServer is failsafe-
connected to a client computer running Compass control
software.
Ethernet LED: Indicates Ethernet activity when RMServer is
connected to a computer running Compass control soft-
ware.
AC Power LED: Indicates when RMServer is receiving AC
power.

PowerCon AC Power Connector: This locking connector
mates with the provided AC power cable.
CAUTION:
Make sure the AC power cable has
the appropriate power plug (on the other end)
for the area in which you will operate RMServer.
NOTE:
RMServer incorporates Meyer Sound's
Intelligent AC power supply, which automati-
cally adjusts for any line voltage between 90 and 264
volts, and provides both soft turn-on and transient
protection.
Relay Outputs: Alert conditions can be signaled to external
devices by changing the state of two onboard relays.
+12V Output: Provides voltage for outboard contact closure
relays connected to RMServer's opto-isolated inputs, such
as those used in fire alarm or other emergency systems to
trigger loudspeaker muting.
TIP:
For more information about connecting
relays to RMServer's inputs, see the sec-
tion"Connecting RMServer" on page 10.
Opto-Inputs 1 and 2: For installations where RMServer is
part of a fire alarm or evacuation system, the active audio
inputs (main program sources) of all devices connected to
that RMServer can be muted using these opto-isolated
inputs. The mute can be triggered with a relay closure
attached to the Opto Input pins. Each pin is triggered when
it receives a voltage 3 to 20 VDC greater than its associated
COM pin. The source of this voltage is commonly the +12 V
output. When triggered, the isolated opto input instructs
RMServer to mute all Mute Enabled connected loudspeak-
ers.
CAUTION:
Do not send voltages greater than
20 V DC to the Logic I/O pins as this may dam-
age the input circuitry.
