1. INTRODUCTION
Unit for automatic changeover to a backup amplifier for Optimax installations.
Supports automatic switching of the line inputs and outputs of faulty power units to power units defined
as backup power units.
Each COU-02/0ETH supports surveillance of 6 power units for switching to 2 backup power units. Each
power unit for which surveillance is required must have a COU-02/ESETH card. In the event of failure,
the card switches 2 analog channels and the loudspeaker line to the backup amplifier.
The unit and each of the COU-02/ESETH cards that it contains are configured by means of the connection
to an ETHERNET network, using the P.A. Manager software.
When the changeover is made from a faulty amplifier to a backup amplifier, the latter automatically
acquires the configurations of the unit it is replacing.
In the event that there are more than two faulty amplifiers, the unit determines which ones are to be
replaced by the two backup amplifiers, according to the priority level assigned to each amplifier.
Operation:
When a fault occurs in a zone amplifier (temperature alarm, disconnection of the two ETH inputs, power
failure or high line impedance error), the FAIL contact of this amplifier is activated. This FAIL, connected
to the CTRL of the COU-02/ESETH card, triggers switching of the zone amplifier for the backup amplifier.
Principal characteristics:
Double Ethernet connection for installations with redundant network systems.
Operation in stand-alone mode or with P.A. Manager control software.
Input/output contacts configurable for backup amplifier fault detection or auxiliary functions.
Surveillance of equipment operation by means of P.A. Manager software and/or basic TELNET
functions.
IP address configuration by means of DIP switches, facilitating the replacement of equipment in an
installation, or remotely by software configuration.
Dispatch of system status alarms.
Front LEDs indicating the status of the amplifiers (OK/FAIL) and the status of the backup amplifiers
(OK/FAIL/IN USE/STAND-BY).
Occupies three units of height on 19'' Rack cabinets.

(2) Ground contact and (3) Chassis contact
In all Public Address installations it is very important
that there is one single point of connection between
the signal ground connection and the mains supply
ground contact.
If the Public Address installation is composed of
several equipment units, their chassis will probably
be joined, either by means of the ground terminal of
the mains connection, or because they are fitted in a
rack cabinet.
If the ground connections are also joined by the
signal circuits, it is advisable to remove the jumper
between the ground connection and the chassis from
all the units except one.

ETHERNET B input.
(14) ETHERNET A connector
RJ45 type connector. Used for connection to
the ETHERNET network. Use Cat 5 STP cable
for its connection.
(15) ETHERNET B connector
RJ45 type connector. Used, in a redundant
network, as a secondary connection to the
ETHERNET network. Use Cat 5 STP cable for
its connection.
If the ETH A connection fails, the amplifier
automatically switches to this B connection,
so that the PA system continues to operate.
(16) IP ADDRESS DIP switches
The IP address of the COU-02/0ETH is configured
through these 4 DIP switches. This address
identifies the equipment unit in the network, and
so each unit must have a unique IP address.
An IP address is represented by means of a 32-
bit binary number. The IP addresses are
expressed as decimal notation numbers: the 32
bits of the address are divided into four octets
(an octet is a group of 8 bits). In the amplifier,
each octet is represented by A0 to A7 for the first
octet, B0 to B7 for the second octet, C0 to C7 for
the third octet, and D0 to D7 for the fourth octet.
In an octet, each bit can have the value 0 (DIP
switch OFF) or 1 (DIP switch ON). In order to
obtain the decimal value of the octet, the decimal
values of each bit that is in the ON position must
be added up (from left to right: 1, 2, 4, 8, 16,
32, 64 and 128).
Figure 6 shows an example in which the IP
address 192.168.100.128 is configured.
Table I on the next page shows all the DIP switch
combinations from 0 to 255.
When the IP address of a unit is changed, it is
necessary to restart the unit by means of the
ON/OFF switch on the front.

4.3. COU-02/ESETH card
Each card supports the switching of two input signals
and the loudspeaker line of the zone amplifier towards
the backup amplifier.
A COU-02/0ETH can house up to 6 COU-02/ESETH
cards.
4.3.1. Fitting the card in the COU-02/0ETH
To fit the cards in the COU-02/0ETH chassis, disconnect
the power supply from the equipment and on the back
of the unit remove the blank panel corresponding to the
slot where you wish to position the card. Put in the card
until completely inserted, applying gentle pressure, and
refit the attachment screws.
4.3.2. Connections
(1) INPUT 1
Audio input. An RJ45 connector is used.
The signal present in this input will be sent through OUTPUT 1 of this
same card. If the amplifier connected to this card fails, this input
signal will be sent through OUTPUT 1 of BACKUP AMPLIFIER 1 or
through OUTPUT 1 of BACKUP AMPLIFIER 2 (see section 4.2.
CONTROL MODULE).
Use Cat 5 STP cable for its connection (see Figure 10).
Activation of the priority contact does not affect the COU-02/0ETH; it is only transmitted towards the
output connector, activating the priority of the UP-ETH corresponding to this output.

By removing internal jumper J1 from the card (see Figures 11 and
16), the shield of the Cat 5 FTP cable is separated from pin 8
(GND). In certain installations, it allows to eliminate alternating
noises caused by ground loops. In this case, to activate the
priority, pin number 6 must be connected to pin number 2.
(2) OUTPUT 1
Audio output. An RJ45 connector is used.
Providing that the amplifier connected to this card is
operative, the audio signal present in this output is the
INPUT 1 signal of this same card.
Use Cat 5 STP cable for its connection (see Figure 12).
By removing internal jumper J2 from the card (see Figures 13 and
16), the shield of the Cat 5 FTP cable is separated from pin 8
(GND). In certain installations, this makes it possible to eliminate
alternating noises caused by ground loops.
(3) INPUT 2
Audio input. An RJ45 connector is used.
The signal present in this input will be sent through OUTPUT 2 of this same card. If the amplifier
connected to this card fails, this input signal will be sent through OUTPUT 2 of BACKUP AMPLIFIER 1 or 2
(see section 4.2. CONTROL MODULE).
Use Cat 5 STP cable for its connection (see Figure 10).
Activation of the priority contact does not affect the COU-02/0ETH; it is only transmitted towards the
output connector, activating the priority of the UP-ETH corresponding to this output.
By removing jumper J3 from the input circuit (see Figures 14 and
16), the shield of the Cat 5 FTP cable is separated from pin 8
(GND). In certain installations, it allows to eliminate alternating
noises caused by ground loops. In this case, to activate the
priority, pin number 6 must be connected to pin number 2.

Notes on Local and Global Co-ordinators
The system requires management of the digital audio channels at all times, so that the data may circulate freely across the network.
This function is performed by two applications: one at a local level, known as LCC, which manages the digital channels at PA Area
level, and another, known as GCC, which manages the digital channels at a global level (between different PA areas and/or servers).
Each PA Area needs at least one LCC process on one of its equipment units.
If there is more than one PA Area in an installation, and announcements have to made or music programs have to be sent between
PA Areas, a minimum of one GCC process is required on an equipment unit in the installation.
If the number of equipment units so permits, it is advisable to have each process available on at least two equipment units. In this
way, the applications continue to work even when a fault in one of the equipment units occurs.
There are specific equipment to run these applications: CC-100ETH, UMX-CC and UMX-ETH (Control). It is recommended that they
are the ones who made the role of coordinator. If these equipment are not present in the installation, it is advisable that the COU-
02/0ETH, performs the functions of co-ordinator.
The recommended order of priority depending on the model is as follows:
CC-100ETH
