INSTALLATION
5.1. Location, assembly, ventilation
The MIMO88 has been especially designed to be installed in a standard 19" rack, taking
up 1U.
It is very important not to enclose the MIMO88 or expose it to extreme temperatures as it
generates heat. It’s also necessary to promote the passage of fresh air through the
ventilation holes of the chassis, leaving at least one rack unit off between each device and
installed above and below it in the rack frame.
If the setup has several amplifiers in the same rack or in a closed cabinet with doors, it is
highly recommended to supply them forced ventilation, installing fans at the upper and
lower ends. This upward air flow will help to dissipate the heat generated inside.
5.2. Connection to an AC outlet and switching on
The MIMO88 operates under voltages between 90 and 264 V at 47 to 63 Hz. This device
features an over dimensioned power supply that adapts to the mains voltage in any
country of the world with no need to make any adjustments.
On the rear panel, there is a power switch for the unit (20) next to the IEC power
connector. On the front panel, a LED (7) lights up when the unit is switched on.
The mains cables must not be near the shielded cables carrying the audio signal, as this
could cause humming.

7
5.3. Signal input connections
The rear panel of the MIMO88 offers 8 balanced analogue signal inputs, "IN" (9),
accepting both line and microphone level signals. Input signal type selection and
management are carried out from EclerNet Manager application. Please refer to the
EclerNet Manager software manual for more information.
Signal input connectors are 3 position screw terminal block. The wiring is:
Hot or direct signal > Terminal +
Cold or inverted signal > Terminal -
Ground > Terminal ⊥
For unbalanced connection short-circuit pin ⊥to pin -.
5.4. Audio Output Connections
The rear panel of the MIMO88 offers 8 analogue
signal outputs, "OUT" (8), and two additional
"MONITOR" (10) outputs, all balanced and accepting
line level signals.
Signal output connectors are 3 position screw
terminal blocks. The wiring is:
Hot or direct signal > Terminal +
Cold or inverted signal > Terminal -
Ground > Terminal ⊥
For UNBALANCED connections, leave the –terminal unconnected.

8
5.5. ETHERNET port for programming and control
A RJ45 type connector (11) allows connecting the equipment to an Ethernet network:
•Management from EclerNet Manager application. Please refer to the EclerNet
Manager software manual for more information.
•Possibility of direct connection (point to point) between a computer and a MIMO88
unit.
•Connection to third party other devices. (Crestron, AMX, Vity, Medialon, etc.
Registered trademarks of their manufacturers). Protocol used: Ecler TP-NET. See
the TP-NET protocol manual for more information.
5.6. LINK BUS digital audio port
A RJ45 type connector (12) allows connecting the equipment to a second MIMO88 unit
for a two-way exchange of digital audio and control data between the two units, the
whole behaving as a real matrix with 16 inputs and 16 outputs. The maximum permissible
distance between the two units using a standard CAT5 cable is 100 meters.
To work in 16x16 mode, one of the two coupled MIMO88 units (linked by BUS LINK)
assumes the role of MASTER and the other one the role of SLAVE. MASTER or SLAVE
mode is set by the selector (13) located on the rear panel of each unit. In single MIMO88
setups, selector position is irrelevant.
In 16x16 mode, the two units behave as a single device with 16 inputs and 16 outputs.
All Ethernet programming and remote control of the MASTER-SLAVE pair is done with
EclerNet Manager application and communication uses the Ethernet port of the MASTER
unit only, it’s not necessary to use the Ethernet port of the SLAVE unit. (Except for
updating the firmware).
Caution: two MIMO88 units coupled by BUS LINK should be linked with a crossover
cable, i.e. with a CAT5 cable dedicated to the BUS LINK ports of both units, up to 100
meters long, and without intermediate Ethernet hardware or other. Please refer to
the EclerNet Manager software manual for more information.

5.7. REMOTE ports 1 and 2 for digital remote controls
The REMOTE 1 and REMOTE 2 ports (14) are two connection
points for the digital bus of remote control devices such as
WPTOUCH wall panel or MPAGE16 messaging console (paging).
Each of them can be connected to a digital bus branch, at which the
various remote devices will be daisy-chained, the last one being
loaded with a 120 termination resistance between CAN HIGH
and CAN LOW.
Refer to the remote device documentation (WPTOUCH, MPAGE16, etc) for more
information about your connection and controls.
Refer to the EclerNet Manager application manual for more information about MIMO88
programming to manage remote devices connected to REMOTE1 or REMOTE2.

10
5.8. GPI Remote Control Ports
The rear panel of the MIMO88 offers 8 GPI inputs (16) for 0-10 VDC continuous control
voltage. Each of these inputs can be connected to an external physical device
(potentiometer, contact closure, continuously variable voltage 0-10V DC, etc.) and
assigned to a MIMO88 function, as for example:
•Input, output channel or matrix crosspoint volume remote control by means of a
WPVOL physical knob or an Ecler WP Series WPVOL-IR remote control
•MUTE or SOLO activation/deactivation by means of a switch or contact closure
•Recalling a preset with a push button or contact closure
GPI connectors are screw terminal blocks with three-contacts. The wiring is as follows:
Positive, + 10 VDC > Pin +
Variable voltage, 0-10 VDC > Pin ↑
Ground > Pin ⊥
WPaVOL connection to MIMO serial GPI ports

Connecting cables can be up to 500 meters with a minimum section of 0.5 mm2.
Consult your ECLER dealer or www.ecler.com about the WP series remote control wall
panels and other accessories available for connection to the REMOTE/VCA port.
5.9. GPO Remote Control Ports
The rear panel of the MIMO88 offers 8 NO/NC (normally open/ normally closed) relay
outputs (17). Each of these outputs may be assigned to a MIMO88 function, such as a
button of EclerNet Manager (MUTE key, SOLO key, etc.). This makes it possible to interact
with external devices such as projection screen motors or movable partitions, lights,
sirens, other equipment GPI entries, etc.3.10. Remote control RS-232 Port
5.10. Remote control RS-232 Port
The built-in RS-232 port in the rear panel allows an external device to communicate with
an MIMO88 unit via a serial connection. Said connection uses the TP-NET protocol syntax
so to enable the external device to obtain the value of any of the parameters of the
MIM088 unit (by "GET" commands) and/or modify said values (“SET” commands). See
the TP-NET protocol manual for more information.
The serial connection should comply with the following specifications:
Baud rate: 57600 (fixed, no auto negotiation)
Data bits: 8
Parity: None
Stop bits: 1
Flow control: None

5.11. Front panel controls and LED indicators
The following elements are available on the MIMO88 front panel:
•MONITOR output (marked with a headphones symbol): it produces the same
monitoring signal already available via the rear panel screw terminal block, but here
on a ¼" TRS jack and with a rotary volume control (2 ) for listening through
headphones. It is especially useful for listening to input or output signals without
disturbing the normal operation. In 16x16 mode both MIMO units receive the same
signal. The monitored signal is selected with EclerNet Manager control software.
Please refer to the EclerNet Manager software manual for more information.
•Input LED indicators: indicate the presence of audio signal at the unit’s input, and
its intensity level (green, amber and red indicate in this order the increased intensity
level)
•Output LED indicators: indicate the presence of audio signal at the unit’s output,
and its intensity level (green, amber and red indicate in this order the increased
intensity level)
•Status LED indicators (STATUS):
oDATA:
▪Off: there is no connection to EclerNet Manager even if connected
to Ethernet.
▪On: connected to EclerNet Manager or to other third party
application via TP-NET protocol. Flashing: data traffic with EclerNet
Manager or another application.
oLINK:
▪1. If the device is configured as 8x8 MASTER, the LED is
permanently off.
▪2. If the device is configured as 16x16 MASTER:
•If everything is correct (SLAVE is connected and there is no
communication error), the LED quickly and continuously
toggles between green (50ms) and unlit (50ms)
•If there is a communication error with the SLAVE, the LED
quickly toggles between green (50ms) and red (200ms)
•If no SLAVE is connected (or if connected equipment is
another MASTER), the LED slowly toggles between green
(800ms) and red (200ms)
▪3. If the device is configured as SLAVE:
•If everything is correct (MASTER is connected and there is
no communication error), the LED quickly and continuously
toggles between orange (50ms) and unlit (50ms)
•If there is a communication error with the MASTER, the LED
quickly toggles between orange (50ms) and red (200ms)

13
•If no MASTER is connected (or if connected equipment is
another SLAVE), the LED slowly toggles between orange
(800ms) and red (200ms)
oPOWER: illuminates when the unit is in operation. It flashes if there is an
error in the unit or if firmware is not correct. It also flashes when you update
firmware
CLEANING
The front panel should not be cleaned with dissolvent or abrasive substances because
silk-printing could be damaged. To clean it, use a soft cloth slightly wet with water and
neutral liquid soap; dry it with a clean cloth. Be careful that water never gets into the unit
through the holes of the front panel.
