Precautions
Before installing, setting up or operating this equipment make sure you have read and
fully understand all of this section and the “IMPORTANT SAFETY INSTRUCTIONS” at the
front of this manual.
This equipment is supplied by a mains voltage that can cause electric shock injury!
The following must be observed in order to maintain safety and electromagnetic compatibility (EMC)
performance.
Safety warnings
Signal 0V is connected internally to the
chassis.
To completely disconnect this equipment
from the AC mains, while observing full
safety precautions (see “Power” on
page xiii), switch off the D.C. POWER ON
switch (above the PSU modules on rear of
unit) and then switch off the mains at the
mains outlet. Isolate the unit by
unplugging the three mains leads from rear
panel.
To avoid electrical shock do not remove
covers.
General precautions
In the event of ground loop problems,
disconnect the signal screen at one end of the
connecting cables. Note that this can only be
done when the equipment is used within a
balanced system.
Do not remove, hide or deface any warnings or
cautions.
Power
The power supplies contain LETHAL VOLTAGES
greatly in excess of the mains voltage and its
rails can produce extremely large currents that
could burn out equipment and wiring if shorted.
The internal power supplies are of the switch
mode type that automatically sense the
incoming mains voltage and will work where the
nominal voltage is in the range 100VAC to
240VAC.
Each mains inlet is to be sourced from its own
separate wall-mounted mains outlet socket.
Otherwise, their mains sources must be suitably
DL371 Audio System Engine
Operator Manual
distributed so as to meet local safety
regulations.
A Volex locking type plug is fitted on each
supplied mains cable, which plugs into a mains
IEC connector on the unit. When fitted properly
the Volex plug locks into place, preventing it
from working loose, or being inadvertently
knocked loose or pulled out. To fit a Volex plug,
insert it into the mains IEC connector and push
it in until it locks in place. Then, check to make
sure it is locked in place. To remove it, release
its locking device and then pull it out. When
fitting or removing a Volex plug, always hold the
plug itself and never use the cable, as this may
damage it.
When removing the equipment’s electric plugs
from the outlets, always hold the plug itself and
not the cable. Pulling out the plug by the cable
can damage it.
Never insert or remove an electric plug with wet
hands.
Do not connect/disconnect a mains power
connector to/from the unit while power is being
applied to it. Switch the power off first.
Handling the equipment
Completely isolate the equipment electrically
and disconnect all cables from the equipment
before moving it.
When lifting or moving the equipment, always
take its size and weight into consideration. If
necessary, use suitable lifting equipment or
transporting gear, or sufficient additional
personnel.
Do not insert your fingers or hands in any gaps
or openings on the equipment, for example,
vents.
xii
Installation
Before installing the equipment:
•
Make sure the equipment is correctly
connected to the protective earth conductor
of the mains voltage supply of the system
installation through the mains leads.
•
Power to the equipment must be via a fused
spur(s).
•
Power plugs must be inserted in socket
outlets provided with protective earth
contacts. The electrical supply at the socket
outlets must provide appropriate
over-current protection.
•
•
Precautions
Electrostatic discharge
(ESD) precautions
Observe full electrostatic discharge
(ESD) — also known as “anti-static”
— precautions when carrying out
procedures in this manual that are
accompanied by the ESD Susceptibility Symbol
(shown above). This caution symbol shows you
that ESD damage may be caused to items
unless proper ESD precautions are taken, which
include the following practices:
•
Keep the work area free from plastic, vinyl or
styrofoam.
Both the mains supply and the quality of
earthing must be adequate for the
equipment.
•
Wear an anti-static wrist strap.
•
Discharge personal static before handling
devices.
Before connecting up the equipment, check
that the mains power supply voltage rating
corresponds with the local mains power
supply. The rating of the mains power supply
voltage is printed on the equipment.
•
Ground the work surface.
•
Avoid touching ESD-sensitive devices.
Location
Ideally a cool area is preferred, away from
power distribution equipment or other potential
sources of interference.
Do not install the equipment in places of poor
ventilation.
Do not install this equipment in a location
subjected to excessive heat, dust or mechanical
vibration. Allow for adequate ventilation around
the equipment, making sure that its fans and
vents are not obstructed. Whenever possible,
keep the equipment out of direct sunlight.
Do not place the equipment in an unstable
condition where it might accidentally fall over.
Make sure that the mains voltage and fuse
rating information of the equipment will be
visible after installation.
Audio connections
To ensure the correct and reliable operation of
your equipment, only high quality, balanced,
screened, twisted pair audio cable should be
used.
XLR connector shells should be of metal
construction so that they provide a screen when
connected to the control centre and, where
appropriate, they should have Pin 1 connected
to the cable screen.
Radio frequency
interference—Class A
device
This equipment has been tested and found to
comply with the limits for a Class A digital
device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable
protection against harmful interference when
the equipment is operated in a commercial
environment. This equipment generates, uses,
and can radiate radio frequency energy and, if
not installed and used in accordance with the
instruction manual, may cause harmful
interference to radio communications.
Operation of this equipment in a residential area
is likely to cause harmful interference in which
case the user will be required to correct the
interference at his own expense.
Electric fields
Caution:
In accordance with Part 15 of the FCC
Rules & Regulations, “… changes or
modifications not expressly approved by
the party responsible for compliance could
void the user's authority to operate the
equipment.”
Should this product be used in an
electromagnetic field that is amplitude
modulated by an audio frequency signal (20Hz
to 20kHz), the signal to noise ratio may be
degraded. Degradation of up to 60dB at a
frequency corresponding to the modulation
DL371 Audio System Engine
Operator Manual
xiii

electrostatic discharge (ESD) precautions are required before
handling the module.
The design of the DL371 Audio System Engine makes module replacement very easy
and straightforward. The unit has rack guides in each of the seven module positions so
that the modules can slide easily in and out. Each module is held in place by two
screws.
To replace a module the only tool you will need is a Torx T10 screwdriver.
>> To remove a module
1
Switch off and electrically isolate the unit, as detailed in “To remove power from
(electrically isolate) the unit” on page 16. Then, disconnect all connectors from
the rear panel.

Appendix E: Service Information
This appendix provides instructions on routine servicing and cleaning, and gives details
on equipment disposal.
Routine maintenance
To help keep your DL371 Audio System Engine unit in good working order and to make
sure it gives you optimum performance, we recommend that you carry out the
following:
Monthly
•
Clean the unit, as detailed in “Cleaning the unit” on page 35.
•
Check functionality of the LEDs. You can quickly carry out a visual check by
switching the unit off and then on again, as they are all activated during power-up.
•
Check functionality of equipment.
•
Clean the internal fans, see “Cleaning the internal fans” on page 21.
Yearly
Cleaning
Switch off the unit and electrically isolate it from the mains before cleaning;
see “To remove power from (electrically isolate) the unit” on page 16.
Cleaning the unit
Clean the unit using a dry, lint-free cloth. Do not use harsh abrasives or solvents.
When cleaning the unit, take great care not to damage the pushbuttons.
Cleaning the internal fans
The unit’s internal fans need to cleaned regularly to remove the build of dust, dirt etc.
We recommend that they are cleaned at least once a year, provided the unit has been
operated under normal conditions. However, if the operating conditions are more
adverse or extreme, for example, if the unit is operated in the vicinity of smoke
machines, new carpets etc., this frequency should be increased accordingly.
This procedure must be carried out by a fully qualified service engineer. If you have
any queries, contact Midas; details can be found at the front of this manual.
Voltage rail failure
When the unit is powered, all three voltage rails must be live. Their status is monitored
by the three LEDs in the psu section of the front panel (see “psu panel” on page 6),
which should all be illuminated. If any one of the LEDs is extinguished, it is probably an
indication of a serious problem and you should contact Midas Technical Support.

Hot unplugging/plugging a PSU module
Caution:
While it is possible to replace a PSU module with power connected
to the other two, this may cause a momentary interruption or noise
on the audio outputs of the unit. Always mute any loudspeaker
system before performing this procedure.
If you have to replace a PSU module, it can be done with the DL371 Audio System
Engine unit switched on. This is known as “hot unplugging” (removing) and “hot
plugging” (fitting), and will enable you to change it quickly and save you having to
disconnect the cables from the unit.
>> To hot unplug/plug a PSU module
1
Mute all outputs (see Caution above).
2
Switch off the power at the mains power outlet of the PSU you want to remove.
3
Remove the mains IEC connector from the PSU module.
4
Remove the two screws (left side of PSU module) securing the PSU module to the
rear of the unit.
5
Pull out the PSU module, using its handle.
6

Appendix F: PRO6 Live Audio System
This chapter provides a detailed overview of the XL8 Live Performance System.
Standard system configuration
The PRO6 Live Audio System is a very powerful and flexible audio processing system
that provides a complete solution for any audio mixing and signal distribution
application in a live sound environment.
Despite its compact size the standard PRO6 offers 56 channel inputs, eight auxiliary
returns, 41 buses (16 auxes, 16 matrices, three masters and six solos), eight on-board
effects processors, PEQs (four-band on inputs and six-band on outputs), eight standard
(up to 36 maximum) 31-band GEQs, eight configurable stereo effects1, 5.1 surround
panning and comprehensive, easy-to-use routing. PRO6 automation provides up to
1,000 scenes with snapshot save/recall capability and global edit, and show file
archiving.
The PRO6 Control Centre forms the core of the PRO6 Live Audio System, which also
includes two 19” rack units — a DL351 Modular I/O (7U) and a DL371 Audio System
Engine (7U) — that are interconnected by a networked data system. The network
carries both proprietary control data and open architecture AES50 digital audio, and
uses readily available standard cabling and connectors. The PRO6 uses a proven stable
Linux operating system. All of the control centre’s internal and network routing
(“patching”) is managed via the graphical user interface (GUI).
Operation of the control surface is intuitive, unique and easy. Its layout is based on
familiar analogue lines to retain that ‘analogue’ feel. To manage the numerous
channels, the PRO6 Control Centre utilises VCA/POP groups and colours, and
additionally there are various navigational controls that aid quick channel/bus access
and selection. A daylight-viewable GUI at the top of the control surface assists
operation and provides extra functionality.
The PRO6 Live Audio System is tolerant of many types of hardware or software failure.
To achieve this the system employs dual redundancy, where a key component has an
identical redundant spare that is ready to take over should it fail. Other failure
scenarios are managed by the N+1 principle, where redundant components form an
acceptable fraction of the system.
The Klark Teknik DN9696 Recorder can be used with the PRO6 Live Audio System for
live multi-track recording and ‘virtual’ sound check. Optional equipment includes the
XL8’s DL451 I/O and DL431 splitter, and the DN9331 RapidE for remote GEQ operation.
1. Each can be configured to generate four additional GEQs, making a total of 36 available on the control
centre (plus one stereo effect).

‘industry standard’ Heritage 3000. Although the PRO6 is designed for the traditional
touring live sound environment, it is also ideal for medium-sized theatre, small house of
worship installations and broadcast. So, being a truly multi-function console in the
Midas tradition, the PRO6 is suitable for many applications, such as:
•
Live sound touring MON or FOH duties.
•
Live sound small theatre MON or FOH duties.
•
Live sound house of worship MON or FOH duties.
•
Live sound broadcast mixer with basic 5.1 surround capabilities and monitoring.

Appendix F: PRO6 Live Audio System
System components (standard supply)
The PRO6 Live Audio System is modular, allowing for some variations in physical
placement and system size. The standard PRO6 touring system package is configured
as a 14U rack (containing two DL3n1 units) in a single, easily portable flight case, with
an equally portable, flight-cased control surface and minimal cabling. This package
comprises:
•
•
1-off PRO6 Control Centre (in a flight
case). Its user-configurable modular
I/O rack (rear panel) will be populated
with the following modules (from top to
bottom):
•
DL443 analogue Jack I/O module,
providing eight Jack line inputs and
eight Jack line outputs.
•
DL441 analogue input (mic) module,
providing eight balanced mic/line
inputs.
•
DL442 analogue output module, providing eight balanced line outputs.
1-off main 14U rack (in a flight case), which houses:
•
1-off DL351 Modular I/O. This is populated with
seven DL441 analogue input modules (56 main
inputs) and a DL442 analogue output module.
There are a total of 56-off XLR mic/line inputs
provided on the system.
•
1-off DL371 Audio System Engine. This is
populated with five cards, the two empty slots
being blanked off. (If the optional N+1
redundant DSP module card is fitted, there will
be six cards and one empty slot.)
•
4-off interconnecting (N+1) rack Cat 5e copper
cables.
•
2-off interconnecting (dual redundant) gigabit
HyperMac Cat 5e copper cables, each 100 m long.
•
8-off mains cables.
FOH and MON
The PRO6 Live Audio System can be used as a front of house (FOH) or stage monitor
(MON) system.
System buses
The PRO6 has comprehensive system buses to suit demanding applications,
comprising:
•
6-off solo buses, routable from all locations and allowing for dual operator and 5.1
use.
•
3-off master buses, routable from the 56 inputs and eight aux inputs, and six aux
buses.
DL371 Audio System Engine
Operator Manual
41
Mix matrix
•
16-off matrix buses, routable from the 56 inputs and eight aux inputs, and 16 aux
buses and three master buses.
•
16-off aux buses, routable from the 56 inputs and eight aux inputs.
All the bus routings (above) provide simultaneous and time aligned mixing of all the
sources, which will be defeatable for minimum latency requirements.
For monitor mixing, the master, matrix and aux buses can all be routed directly from
the input channels with independent level controls providing up to 35 monitor mix
buses.
For traditional FOH sub group mixing, any (or all) of the aux buses can change to
operate post-channel fader and pan (that is, aux gain fixed at unity).
Auxiliary inputs have two modes of operation: effects return and input channel. In
input channel mode (default) they will have aux, master and matrix routing, insert
points and EQ (like regular inputs channels), but no dynamic capability. They are
controlled like regular inputs from the input bay and channel strip, and are time aligned
to the stage like regular input channels. In effects return mode the channels have
routing to matrix and masters only and no insert or dynamic capability. They are
controlled from the aux return area and time aligned to the effects engines.
Mix matrix
Ultimately, the mix matrix defines the capability of the PRO6 Control Centre. Probably
the best way to imagine the mix matrix is to think of an analogue console layout, where
inputs run vertically and buses run horizontally. A mix matrix is usually defined as the
number of buses and the quantity of simultaneously-mixable inputs there are per bus.
The following diagram illustrates the capability within the control centre.

Effects processing and GEQs
The PRO6 contains eight mono Klark Teknik (KT) GEQs and seven effects processors as
standard.
The seven effects processors can be freely chosen from:
•
KT DN780 reverb.
•
Delay.
•
Flanger.
•
Phaser.
•
Pitch shifter.
•

•
Assign to any insert send/return.
•
Assign to any pool, in or out.
•
Assign FX out to aux return.
•
Assign FX in to aux send (post-fade).
•
Assign FX out to bus direct in.
•
Assign FX in to channel direct out.
A Klark Teknik DN9331 RapidE motorised fader GEQ controller can be used with the
PRO6. This unit provides rapid adjustments of the graphics with real hardware, and not
a mouse and screen. The graphic channel is selected either by the SOLO button (solo
tracking system (STS™)) on the PRO6 Control Centre or by buttons on the RapidE itself.
Audio physical connections
The total number of audio connections, that is, the XLR count, for a standard PRO6 Live
Audio System is 96. This includes dedicated and configurable XLR connections. The
dedicated XLR connections on the DL351 Modular I/O comprises 56-off mic/line inputs.
All of the configurable connections are on the PRO6 Control Centre, which can be freely
located at the FOH or on stage. Three banks of sockets (eight XLRs each) are available
for:
•
8-off 1/4” TRS analogue mic/line inputs (returns) and 8-off 1/4” TRS analogue
outputs (sends).
•
8-off AES/EBU XLRs providing eight digital inputs and eight digital outputs per
module.
•
8-off XLR analogue inputs.
•

Surround capabilities
45
Surround capabilities
Theatres and broadcast have differing requirements for surround and both are catered
for in the PRO6.
Conventional stereo and SIS™ panning is assignable on a channel by channel basis
(channel one can be in stereo while channel two can be in SIS™), as follows:
•
Stereo left–right routing to master buses.
•
SIS™ left–right–centre routing to master buses.
Three additional surround modes operate as follows:
•
Quad left – Right – LS – RS routing to Matrix 1, 2, 5 and 6.
•
Surround Left – Right – Centre – Surround routing to Matrix 1, 2, 3, and 5 and 6.
•
5.1 Surround Left – Right – Centre – Sub – LS – RS routing to Matrix 1, 2, 3, 4, 5
and 6.
Network
The MidasNET network of the PRO6 utilises the physical connectivity of Ethernet
(EtherCon® connectors and Cat 5e/copper cable), but replaces its data protocol with
AES50 protocol (implemented as SuperMac) and the HyperMac high capacity system,
which are more suited to high quality, low latency audio distribution. The use of the
AES standard allows straightforward interfacing with any third party hardware that also
utilises this connection.
MidasNET connections carry digital audio, control data and standard Ethernet traffic
bi-directionally down a single cable. Cat 5e cable is used for the ‘local’ connections and
the single digital ‘snake’ (equivalent to a 384-channel analogue multi-core) between
control centre and DL371 Audio System Engine. The combination of audio, control,
clock and third party Ethernet data in a single network means that the hardware
interfaces on a single RJ45 connection.
All system connections are duplicated for full dual redundancy.
Reliability (redundancy)
All critical system connections and most components incorporate integral backup and
recovery strategies such as redeployment of resources, N+1 or dual redundancy etc. A
modular approach to software, hardware and physical construction also aids reliability
and simplifies servicing. The following lists some examples:
•
The DL371 Audio System Engine incorporates N+1 redundant power supplies and
five modules, with the capability to fit an optional sixth spare module. The standard
failure recovery for modules will be redeployment of critical roles typically causing
loss of some less important inputs. With the optional sixth module fitted, the system
will operate as N+1 and there will be no loss of function after redeployment.
•
The router is contained in the same rack and incorporates dual HyperMAC
connections in and out.
•
The control centre contains dual redundant master controllers, dual GUI screens and
N+1 redundant power supplies.
•
The I/O is modular in blocks of eight to limit the potential for total audio connection
failure and incorporates dual redundant power supplies.
This resilience strategy provides high reliability performance at a reasonable cost
because it is designed in from the start and not as an afterthought.
DL371 Audio System Engine
Operator Manual
46
Appendix F: PRO6 Live Audio System
Control software
The operating system of the PRO6 is Linux, which is an open-source, stable, proven
operating system (OS). Linux is used in many mission-critical applications worldwide
and has allowed Midas’ software engineers to write a ground-up system that contains
no ‘hidden’ or unused code. This has resulted in an efficient, compact application,
which is quick in operation, quick booting and comparatively easy to debug.
Two copies of the master control software run on separate processors to provide
resilience to failure.
GUI
The PRO6 has two, daylight-viewable, TFT screens that provide fast zone and channel
strip status indication. Although, any screen can display any information but, in the
standard configuration, screen information relates to module location. So, the mix bay
screen displays the channel strip and fast zone (12 inputs and 16 outputs), while the
master bay screen displays the channel strip input fast zone (four inputs) and all
meters. The master bay screen is also generally used for automation, effects, GEQs,
third party screens etc., although this is dependent on the current application (concerts
will probably be different to theatre) and also operator preference.
The screens are controlled from the primary navigation zone at the bottom of the
master bay via two trackballs. A USB keyboard (supplied) is used for text editing.
System card expansion
Additional digital I/O format options will be available later, for example, MADI.
Console linking
You can link two PRO6 Control Centres together. Just connect an AES50 cable from a
spare AES50 port on one router to a spare port on another, and then set them up
“Generic AES50” connections in the GUI menu’s Patching screen.
Integration of third party hardware/software
The PRO6 network includes the capability to interface any third party hardware that
uses AES/EBU or AES50 digital audio, or standard analogue audio interface.
Each PRO6 AES/EBU input and output has a sample rate converter. Synchronisation to
external AES3 interfaces can be:
•
Global - via inputs on the routers.
•
Local to each input.
•
Local to each output (synchronisation to adjacent local output).
Multiple local connections can be at different sample rates.
The use of the AES50 protocol for the transmission of digital audio means that any third
party digital audio hardware that features this connection can be connected to the
Midas network, and will transfer audio to and from the Midas hardware without any
additional interfaces or converters (provided it runs in TDM 96kHz mode). This will be
particularly useful as the protocol gains acceptance with recording and playback
devices, loudspeaker controllers, audio networking systems, digital amplifiers etc.
DL371 Audio System Engine
Operator Manual
Integration of third party hardware/software
47
PC or MAC computers can use the Ethernet tunnel in the MidasNET system, and can
communicate with other computers on the network.
The PRO6 Control Centre features an external video for both screens, and the master
bay GUI screen (on the right) also has a three-way KVM switch. Control centre views
can be routed to external monitors, and external video sources can be displayed on the
control centre.
The KVM switch facilitates the control of three external computers via the screen,
trackball and keyboard of the control centre. This is hugely important and means that
third party systems can be controlled from within the PRO6 without having to move
your head to look at screens placed off to one side. It also means that there is no need
to find somewhere to put multiple keyboards and mice. Examples are:
•
Netmax (AES/EBU audio link initially and CobraNet™ when the 48kHz I/O module is
available on PRO6).
•
IRIS (for example, for RL amps).
•
Wireless mic controllers.
•
Your email.
•
DVD movies.

Unpacking the equipment
After carefully unpacking the equipment, check it against the packing list shown in
“System components (standard supply)” on page 40“System components (standard
supply)” on page 26.
Save all packing materials, as they will prove useful should it become necessary to
transport the equipment later.
Inspect the equipment carefully for any sign of damage incurred during transportation.
It has undergone stringent quality control inspection and tests prior to packing and was
in perfect condition when it left the factory. However, if the equipment shows any signs
of damage, notify the transportation company without delay. Only you, the consignee,
may institute a claim against the carrier for damage during transportation.
Making up a rack
In the standard supply, the rack supplied with the PRO6 Live Audio System is fully fitted
with the DL351 Modular I/O and DL371 Audio System Engine units.
Wiring instructions
Connect the snake (Cat 5e or fibre optic) to the DL371 Audio System Engine unit and
PRO6 Control Centre (see Figure 2 “Standard system configuration” on page 50).
The DL351 Modular I/O and DL371 Audio System Engine units should already be
connected together when you receive them.

Important:
The PRO6 Control Centre, DL351 Modular I/O and DL371 Audio System Engine
all have Volex locking type plugs fitted on their supplied mains cables, which
plug into their mains IEC connectors. When fitted properly the Volex plug
locks into place, preventing it working loose, or being inadvertently knocked
loose or pulled out. For details of how to fit/remove a Volex plug, see “Power”
on page xi.

Powering the PRO6 system
The following details the recommended power up and power down procedures for the
PRO6 system.
Note: If you are in any doubt as to how to switch the DL3n1 units on/off, refer to their
operator manuals.
>> To power up the PRO6 system
Important Note:
DO NOT switch on the speaker sub-system until after the start-up of the PRO6
system has been completed.
After all PRO6 system interconnections have been made (refer to Figure 2 “Standard
system configuration” on page 50), start up the PRO6 system:
1
Make sure that all of the PRO6 system equipment is switched off, such as the
PRO6 Control Centre, speaker sub-system, DL351 Modular I/O unit and DL371
Audio System Engine unit.
2
Switch on the PRO6 Control Centre (see “To switch on the PRO6 Control Centre”
on page 52).
3
In the master bay of the PRO6 Control Centre, move all of the monitor and
master channel faders to the minimum position and mute all of the master
channels.
4
Power up the PRO6 components, such as the DL351 Modular I/O unit and the
DL371 Audio System Engine unit. This can be done in any order you like.
5
After the status indicator at the top of each GUI screen has
changed to green (as shown right), switch on the speaker
sub-system.
6
Switch on the audio source and start playing the audio.
7
On the PRO6 Control Centre, check that the audio inputs are routed to the master
channels. Then, unmute the master channels and gradually increase their faders
while listening to the sound levels from the speakers.
If there is no sound at all coming from the speakers when the faders are at maximum,
move the faders to below the 0dB level and check if the audio is muted somewhere
along the input paths and also check that the individual speakers are switched on. If
there is still no sound from the speakers, see “No audio” on page 73.
>> To power down the PRO6 system
Important Note:
BEFORE switching off any of the PRO6 system components, don’t forget to
mute the audio from the speakers and switch off the speaker sub-system.
1
Mute the audio from the speakers and switch off the speaker sub-system.
2
Switch off the DL351 Modular I/O unit.
3
Switch off the DL371 Audio System Engine unit.

Setting up the DL351 Modular I/O unit ID
After connecting up your PRO6 network system, you may need to set up the ID of the
DL351 Modular I/O unit, which is done via its control panel (see Figure 3 below). You
only need to do this if the unit is not already configured to the ID you want; there are
four ID numbers available (1 to 4) and the default is ID 1. The unit’s ID number is
shown at the end of the bottom line in the default display, for example, the ID of the
unit shown in Figure 3 is “1”.
To change the ID number there is no need to switch on the PRO6 Control Centre, as the
procedure can be carried out offline.
