Welcome
Thank you for purchasing this Cloud DCM1/DCM1e, which
combines the traditional simplicity of Cloud products with
far greater functionality. We are condent that you will be
pleased with its performance, features, exibility and reliability.
The DCM1 is Cloud’s digitally controlled zone mixer. It
combines traditional “installer-friendly” analogue I/O and
signal path, with the exibility and adaptability of digital control.
The Ethernet-enabled DCM1e version allows the control and
conguration of the unit to be performed remotely, using a
standard Internet browser.
Scope of this manual:
This manual provides a comprehensive guide to the features
and functionality of the Cloud DCM1 and DCM1e Digitally
Controlled Zone Mixers. Please read through it to become
fully acquainted with the many conguration and control
functions it offers.
DCM1 and DCM1e variants:
This Installation and User Guide covers two DCM1
variants – the DCM1 and the DCM1e.
Note that the DCM1e has various additional features not
available in the DCM1; however, all DCM1 functionality is
provided by the DCM1e.
Certain sections of the Guide cover topics that are only
relevant to the DCM1e; these are clearly indicated by
this
all text references to “DCM1”, and all information and
instructions may be taken as being applicable to either
version, unless specically stated otherwise.
logo. Otherwise, throughout the Guide,
It is recognised that the tasks of design/set-up, physical
installation and day-to-day operation of an audio system
based on the DCM1 may be performed by as many as three
different people. You will nd, therefore, that this manual is
divided into sections:
Overview – introduction to the DCM1 and its
options. Everyone should read this.
Installation – wiring the DCM1 in a practical
situation. This should be read by the engineer
performing the installation and wiring.
Conguration – setting the system up. This
should be read by the systems designer/engineer
who will congure the system to suit the user’s
particular requirements.
Software control. Read this section if you want to
use the Utility Tool to congure the DCM1, or use
the Ethernet browser interface of the DCM1e to
control the unit from an external computer, tablet
or other device.
Appendix – additional technical information.
Includes notes about controlling the DCM1 remotely
via RS-232, and using multiple DCM1s to create
larger systems.
User Templates – User’s operating
instructions. A set of blank templates which can
be completed and left with the user when the
installation is nished, “personalising” the DCM1’s
menu system to the particular installation.
The manual includes details of the optional CDR-1 remote
control plates and the various optional remote input modules.
This information is also supplied with each item when they
are purchased separately.
Thank you again for placing your condence in Cloud products.

DCM1 & DCM1e Installation and User Guide v1.05
Section 1: Overview
Introduction
The Cloud DCM1 is an analogue audio Multi-Zone Mixer. A
digital control system, using a front-panel LCD display and
a simple, minimal set of controls replace the relatively large
number of switch and rotary controls found on conventional
units, yet provide far greater exibility of conguration than
would be possible with such units. It provides a wide range
of input and output connectivity possibilities to suit most
practical situations. It also offers simple and exible remote
control in addition to front-panel operation.
The DCM1 has been designed to provide a simple, reliable
and elegant method of providing audio in a number of
different zones, typically the various areas of shops, bars,
hotels, schools, conference centres, ofces, factories and even
private residences. Local (per-zone) remote control of music
source and level can be simply provided in as many of the
zones as necessary. The DCM1 has been designed to allow
easy integration with mic and line external inputs, paging
microphones and re alarm systems. Once set up, the DCM1
allows zones to be combined (and separated) simply, as space
utilisation of the building demands.
An important aspect of the DCM1’s design is that it is
completely self-contained, and can if wished, be completely
congured and controlled without a computer interface of
any kind. If a computer interface is preferred, the DCM1
Utility Tool software application may be downloaded free of
charge from www.cloud.co.uk. The DCM1e variant includes
the additional capability of being congured and controlled
from an Internet browser running on any compatible device
via an Ethernet connection.
The DCM1 allows connection of up to eight line-level sources
such as CD players, audio jukeboxes, PC sound cards, radio or
TV tuners, etc. In addition, both Cloud paging microphones
(PM or CDPM Series) and third-party paging systems may
be directly connected. Each of the eight outputs is intended
to supply audio to a separate zone. Two of the zone outputs
are available in stereo. Any one source can be routed to
any zone, and the music level in each zone can be adjusted
independently.
List of Main Features
• 8 stereo line inputs (1 balanced)
• 8 balanced line outputs (2 stereo + 6 mono)
• 4 dedicated ports for optional remote line input
modules
• 4 dedicated ports for optional remote mic input
modules

and CDR-1)
• 4 denable zone groups
• Any line input may have priority in any zone; operation
also congurable per-zone
• Key-protected “Installer” mode (both DCM1 and
CDR-1) prevents user access to conguration menus
• Inputs, zones and groups can be named
• Ethernet port for remote control from standard
Internet browser (DCM1e only)

The capabilities of the DCM1 and DCM1e are explained in
greater detail in System Capabilities on page 9.
DCM1 & DCM1e Installation and User Guide v1.06
System Components
DCM1/DCM1e
The DCM1 (or DCM1e) is the system “core” and all the
primary audio input sources, zone amplier inputs, paging
mics/control and all remote controls are connected directly
to it. The DCM1 mainframe should ideally be rack-mounted
along with the audio sources and zone ampliers, in a central
equipment area.
A practical multi-zone audio system is perfectly realisable with
a DCM1 alone, but system exibility and ease of operation
will be greatly enhanced by the addition of optional Cloud
remote controls and/or local input modules.
Installing a DCM1e will add the considerable advantage of
external control from a laptop, tablet or other compatible
device using a standard browser application.
Optional components
CDR-1 Series
The CDR-1 provides the user with local source selection and
level control for the zone in which it is tted. It additionally
allows selection of any zone groups to which the zone has
been assigned, which gives simple and complete control
over audio in multiple areas which may be split or joined in
different ways at different times.
Once enabled on the DCM1 and a local key code entered,
zone EQ is also adjustable from the CDR-1, allowing audio
optimisation from within the zone itself. An Installer Mode
permits zone assignment and adjustment of other installation
parameters.
CDR-1 variants:
Throughout this manual, all references to “CDR-1” apply
equally to the CDR-1 and the CDR-1F.
LE-1 Series
The CDR-1 Series is a range of remote control plates
specically designed for use with the DCM1. They are
available in formats suitable for surface mounting (CDR-1)
or ush mounting (CDR-1F), and also in various nishes. They
may be tted into standard electrical back boxes in whatever
location is convenient in each zone. Any zone may have one
CDR-1, more than one, or none at all. The DCM1 can support
up to 100 CDR-1s. CDR-1s are interconnected with just one
standard Cat 5 UTP cable; units may be daisy-chained at will
and/or connected individually back to the DCM1’s four CDR
ports using almost any wiring topology convenient for the
installation.
The DCM1’s own PSU has the capacity to power up to 8
CDR-1s directly, via the Cat 5 connections. However, please
note that the actual number that can be powered directly
is also dependent on cable length. Full details are provided
with each CDR-1; also see “Cable length and DC power
considerations” on page 21.
LE-1 version illustrated
The LE-1 Series is a range of input connector modules which
can be installed wherever required. Versions are available to
t standard UK (LE-1) or US (LE-1A) dual-gang electrical
back boxes, or in a “Media” format (LE-1M), which ts a Euro-
style 100 x 50 mm mounting frame.All versions are available
in either black or white. They allow connection of a stereo
unbalanced line-level audio source, such as a portable music
player, laptop, radio mic receiver or similar, and connect to
one of the DCM1’s Extension Ports with a single screened
Cat 5 cable.
Multiple LE-1s may be “daisy-chained” together to provide
input points at different locations in the same zone. Signals
applied to modules wired in this way will be summed together.
An internal gating circuit on each module automatically
“disconnects” any chained modules which are not in use, to
minimise noise contribution.
The LE-1’s inputs are electronically buffered to minimise noise
and interference pickup, and input gain is locally adjustable
with a preset control. Two types of input connector are
provided for user convenience: dual phono sockets and a
3.5 mm stereo jack socket; ±12 dB of gain trim adjustment is
available on the faceplate.
Any audio connected to an LE-1 is treated as any other source
and can be routed to any zone in the same manner.
DCM1 & DCM1e Installation and User Guide v1.07
BE-1 Series
BE-1 version illustrated
The BE-1 Series is a range of input connector modules of
similar type to the LE-1. They provide a stereo balanced linelevel input, permitting professional audio equipment with
balanced outputs such as mixing consoles or DI boxes to be
connected. Like LE-1s, they connect to one of the DCM1’s
Extension Ports with a single screened Cat 5 cable.
BE-1s may be daisy-chained in the same way as LE-1s, and the
two types of module may be intermixed.
Two industry-standard latching 3-pin female XLR connectors
are tted.
Any audio connected to the BE-1 is treated as any other
source and can be routed to any zone in the same manner.
ME-1 Series
PM Series Paging Microphones
The Cloud PM Series of paging microphones integrate directly
with the DCM1 and provide a simple and convenient method
of adding multi-zone paging facilities to the audio system.
Multiple PMs can be easily daisy-chained if more than one
paging location is needed.
PM paging microphones are available in 4, 8, 12 and 16-zone
versions, The 4- and 8-zone versions are also available as ‘SA’
versions, with internal digital sound stores for pre-recorded
announcements. The PM1 single-zone mic is also compatible
with the DCM1.
Note that the earlier Cloud CDPM range of paging
microphones is also directly compatible with DCM1 mixers.
ME-1 version illustrated
The ME-1 Series of input connector modules provide one
(ME-1M) or two (ME-1, ME-1A) balanced microphone
inputs, and are useful in multi-purpose areas where mics are
sometimes needed. ME-1 modules have adjustable mic level
and EQ per input, and connect to one of the DCM1’s four
dedicated Mic Inputs with a single screened Cat 5 cable. On
the two-input versions of ME-1, the inputs are mixed together
at the module, and the summed mic signal applied to the
DCM1.
Any of the DCM1’s mic inputs can be routed to any zone
without restriction.
Inputs on the ME-1 are via latching 3-pin female XLR
connectors. 12 V phantom power is available on either input
if required (set via a jumper accessible from the rear of the
module).
Full installation and operation instructions are supplied
separately with each paging microphone.
Cloud DCM1 Utility Tool
This is a simple software application which allows the DCM1
to be congured using serial data commands, either via its
RS-232 port or Ethernet port* from an external computer
or other compatible device. Most of the unit’s menu functions
are available in the Utility Tool, and it provides a convenient
method of pre-conguring a DCM1 off-site, and then loading
all the settings into the unit at a later time.
The Utility Tool is freeware, and can be downloaded from the
Cloud website, www.cloud.co.uk.
A description of each DCM1 menu function can be found in
the “Conguration” section of this manual: all corresponding
Utility Tool functions are denoted here by the
symbol.
A full description of the Utility Tool can be found on page 58.
* An updated version of the Utility Tool additionally allowing serial-via-TCP/IP
over an Ethernet connection will be available during 2014.

Music sources and routing
• Provision for eight music sources. Inputs are stereo, line-
level and unbalanced
• Input 8 also available as a balanced input
• Inputs 1 to 4 may be fed from LE-1 or BE-1 input
modules (see above), which have a balanced connection
via dedicated input sockets
• Any music source may be routed to any zone
• Inputs available for selection may be dened, per-zone
Microphone inputs
• Provision for four ME-1 mic input modules, each of
which can accept two microphones (except the single-
input ME-1M).
• Each mic input assignable to any zone in any
combination
Paging mic facilities
• RJ45 digital interface for PM/CDPM Series paging
microphones
• Additional balanced input for third-party paging mic
• Per-zone contact closure routing for third-party mic
• Both PM and third-party systems may be used together;
independent gain controls.
• HF/LF EQ adjustment of paging signal
• Paging level independently adjustable per-zone
• Zones may be assigned in any combination to four Groups
• Groups can be enabled/disabled by user as required
• Groups have same source selection functions as zones
Priority and Logic
• Any music source may be assigned as priority line input,
per-zone/group. If enabled, a signal at the priority input
overrides the source selection in the zone/group
• Priority music source may be a source normally
unavailable to a zone
• One or more priority mic inputs may be similarly
dened; an active mic signal causes the music level to
reduce (“ducking”)
• During Paging, music ducking may be triggered by the
paging signal or zone selection; it can also be disabled;
these options are selectable per-zone/group
• Independently adjustable hold and release times for all
priority types, plus music attenuation (ducking) level for
mic and paging priorities
Remote Control
• Optional CDR-1 dedicated remote control for DCM1
available separately
• Up to 100 CDR-1s may be connected to the four
CDR-1 Ports, using standard Cat 5 UTP cable
• CDR-1s can be daisy-chained and/or wired directly to
the CDR-1 Ports as cabling convenience dictates
• Multiple CDR-1s per-zone permitted
• CDR-1 provides local (in-zone) user control of source
selection and level control and key-protected EQ
adjustment

1. Line 1 to 4: inputs for music sources 1 to 4, on phono
sockets (unbalanced).
2. Extension Ports 1 to 4: These are alternative input
connectors for Line Inputs 1 to 4. If Cloud remote line
input modules (LE-1 or BE-1) are being used, they should
be connected here via screened Cat 5 cable and shielded
RJ45 connectors. These ports each provide a stereo
pair of electronically-balanced inputs, together with DC
power for the active circuitry in the remote module.

(
connected to a remote input module.
3. Line 5 to 7: inputs for music sources 5 to 7, on phonos
only.
4. Line 8: Input 8 is available both as unbalanced on phonos
and electronically-balanced on 2 x 3-pin 3.5 mm-pitch
screw-terminal connectors. The balanced input allows
connection of professional audio equipment such as
mixing consoles, DJ desks, etc.
5. Microphone Inputs 1 to 4: four shielded RJ45 sockets
for the connection of Cloud ME-1 microphone remote
input modules. Connection should be via screened
Cat 5 cable. These inputs are balanced, and the connectors
additionally provide DC power for the active circuitry in
the input modules.
6. Paging microphone input: balanced input for the
connection of an external paging microphone. This input
7
is enabled via the access connector
. Adjacent to the
3-pin 3.5 mm-pitch screw-terminal connector are preset
controls for mic gain and HF/LF EQ. Phantom power is
available at this input (enabled by internal jumper).
7. Paging Access connector: 10-pin 5 mm-pitch screwterminal connector providing several functions. If the
DCM1 is being used with a third-party paging system,
this connector provides contact-closure selection of the
zone(s) to be paged. If a Cloud PM Series is the only
type of paging system being used, the connector can be
used as an output port, the 8 pins becoming per-zone
open-collector outputs which can be used (typically)
14
for external level restoration. If the connector is not
required for paging access, it can be congured as a GPIO
port (with any combination of inputs and outputs), and
used in conjunction with the RS-232 port to respond to
serial commands (GPO) or report input status (GPI). 0 V
and +12 V are also available on the connector. See page
33 for more information.
8. Zone Outputs 1 and 2: electronically-balanced outputs
on 3-pin 3.5 mm-pitch screw-terminal connectors. Zone
Outputs 1 & 2 are stereo; separate L and R connectors
are provided. Stereo music sources routed to Zones 1
and 2 will remain in stereo. Either Zone Output can be
recongured as mono via the menu system.
9. Zone Outputs 3 to 8: as Zones 1 and 2, but mono only,
with a single connector. These zones will receive a mono
L+R sum of stereo inputs routed to them.
10. Paging level controls: each Zone output has an
adjacent preset control which sets the volume of the
paging mic (either from PM or third-party systems) in
that zone.
11. CDPM/PM ports: two RJ45 sockets, IN and THRU.
IN is for the connection of Cloud PM Series (or CDPM
Series) paging microphones; THRU is used when a system
employs multiple DCM1s. DC power, zone selection data
and the paging microphone signal are all catered for on
the IN socket. The adjacent preset control adjusts the
PM microphone level.
12. CDR-1 Ports: four RJ45 ports for connection of
CDR-1 (or CDR-1F) remote control plates. Plates may
be daisy-chained, and the installer may use one or more
of the four ports for individual or daisy-chained plates as
the building layout dictates.
13. RS232 serial interface: a 9-pin female Dsub
connector providing a bi-directional RS-232
interface. This has several functions: it permits
control of the DCM1’s primary functions from an
external system and can be used in conjunction
with the Paging Access connector in GPIO mode.
On the DCM1e only, it can transmit serial
DCM1 & DCM1e Installation and User Guide V1.01515
commands to third-party equipment in response to
Ethernet commands generated elsewhere (future
rmware release).
14.
ETHERNET INTERFACE: standard
RJ45 network connector allowing the DCM1e to be
controlled and congured from an Internet browser.
In a future rmware release, it will also accept control
commands using RS-232 syntax, and be used as an
Ethernet-to-serial bridge to pass TCP/IP commands from
third-party control systems to the RS-232 connector
13
*.
15. Music Mute input: 2-pin 5 mm-pitch screw terminal
connector for interfacing the DCM1 to a re alarm or
other emergency system. The input is congurable for
use with either Normally Open (N/O) or Normally
Closed (N/C) contacts; shorting (or removing a short)
will mute music in all zones (see “Congure Music Mute”
on page 45). One input source may be protected from
this mute if wished, permitting the input to be used for
automatic or manual evacuation messages (see “Select
Emergency Source” on page 44).
16. POWER: Locking 4-pin power mini-DIN type for
connection of the DCM1’s external DC PSU.
* Ethernet-to-serial bridge functionality will be available in a future rmware
release. Please check www.cloud.co.uk for additional product features.
DCM1 & DCM1e Installation and User Guide v1.016
Hardware considerations
The DCM1 is built in a 2U-high 19” rackmount enclosure. It
is strongly recommended that the DCM1 is installed
in a 19” rack wherever possible. The DCM1 is approx.
160 mm deep, but 250 mm of rack depth should be available
to allow for rear connectors and cabling.
The DCM1 has low power consumption and there are
no thermal considerations other than ensuring that the
ventilation grilles (one on each side, one on the bottom panel)
are not obstructed once installed. Other equipment may be
installed above or below the DCM1 within this constraint.
The choice of location will be dictated by the specics of the
system and building layout. It is recommended that wherever
possible, the DCM1 should be mounted in an equipment rack
along with as many of the music sources (CD players, music
servers, TV receiver boxes, etc.) and audio power ampliers
(driving the zone loudspeakers) as practical.
When deciding the DCM1’s location, bear in mind that access
to it may be required, as there are some conguration settings
that may need to be changed - occasionally or frequently depending on the daily requirements of the building. This is
more likely to be the case with a DCM1 than a DCM1e, as
the latter allows many setting to be adjusted remotely from
an external device.
Power Supply
The DCM1 requires ±12 V DC, which is supplied by the
external DC Power Supply Unit (PSU) included with the unit.
This has a 1 m captive cable with a moulded 4-pin plug for
connection to the DCM1. The PSU is of the “Universal” type,
and will operate on any AC supply voltage from 100 to 240 V.
Wherever possible, mount the PSU in a safe location within
the equipment rack, securing both the DC cable and the IEC
mains lead with cable ties to avoid inadvertent disconnection.
System Connections
Music Sources
Connect the system’s various music sources to LINE 1 to 8.
When allocating sources to inputs, bear in mind that if Cloud
LE-1 or BE-1 remote modules also form part of the system,
these can be connected to LINE 1 to 4 only.
Standard connection:
All eight line inputs offer unbalanced connection for stereo
sources on a pair of standard phono sockets (RCA jacks).
The sensitivity range available should allow most standard
items of audio equipment such as CD players, PC-based music
servers, TV tuners, etc., to operate at a satisfactory level. Such
equipment will generally have stereo unbalanced outputs, and
as long as the source equipment is adjacent to the DCM1,
normal phono-phono leads can be used.
Mono sources:
If connecting a source with only a single mono output to
the DCM1, connect it to both the L and R sockets, using a
Y-splitter lead or similar.
Balanced sources:
LINE 8 is additionally provided with electronically-balanced
inputs, which may be used to connect source equipment with
balanced outputs. Balanced connection is always preferable to
unbalanced for situations involving long cable runs, and should
be used if one of the music sources is remote from the DCM1
(a DJ mixing system is a common example).
When connecting balanced sources to LINE 8’s balanced
input connector, wire as shown below. Note that the cables’
screens are not connected at the source end.

Additional balanced sources:
If it is necessary to connect more than one balanced source
to the DCM1, one of the unbalanced inputs 1 to 7 may be
used, but the advantages of balanced connection will be lost
unless a balancing transformer is connected between the
source and the unbalanced input. Suitable audio transformers,
which should have a ratio of 1:1, are readily available from
major audio component suppliers. The transformer(s) should
be mounted as close to the DCM1 as practical, and housed in
a screened enclosure if they are not individually screened. The
preferred connection method is shown below.

If transformers are not available, a balanced source may feed
an unbalanced input directly as long as care is taken over how
the connections are made. A variety of design techniques are
in use to implement balanced outputs in audio equipment,
and some designs require different wiring protocols to others.
Installers are advised to check the manuals with each item
for guidance on how the outputs should be connected to an
unbalanced input.
However, the wiring methods shown below will work in a
large number of cases. If hum or other distortion is found to
result, try disconnecting the ‘cold’ leg of the balanced output
(pin 3 on XLRs).

connector.
Standard connection:
All eight outputs provide balanced connection for wiring to
professional/industrial power ampliers with balanced inputs

CDR-1 Remote Control Plates
Multiple CDR-1 or CDR-1F remote control plates may be
connected to the DCM1 either by wiring them directly and
individually, or by “daisy-chaining” them together. In most
installations, a combination of these methods is likely to
be the most convenient solution from the point of view of
practical cabling. The diagrams below illustrate the types of
wiring schemes that may be employed; almost any variation
on these is permissible.

Note that in the above diagrams there is deliberately no
indication as to which zones any of the CDR-1s are in; this is
because the system imposes no restriction on their physical
location. Interconnection may be made purely on the basis of
wiring convenience.
Connections
CDR-1s are connected to the DCM1’s CDR-1 PORTS
using standard unscreened Cat 5 cable and RJ45 connectors.
It may be possible to use pre-made Cat 5 “patch cables” to
connect any CDR-1s installed close to the DCM1; otherwise
Cat 5 cable and crimp RJ45 plugs should be used. NOTE:
All Cat 5 cabling should be wired “pin-to-pin”; “crossed” or
“null” cables will not work.
Wire the RJ45 connectors according to the pinout diagram
on page 69.
Note that the single Cat 5 interconnection provides DC
power as well as data. A full pin allocation of the CDR-1 ports
can be found in the Appendix at the end of this manual.
Any of the four CDR-1 PORTS may be used. Two of these
are labelled PORT A and the other two PORT B, but the
four are electrically identical. However, use of Port A or Port
B has relevance to how terminations are set (“Network
Terminations” on page 21).

The CDR-1 and CDR-1F are equipped with two RJ45

The “rst” CDR-1 in a daisy-chain wiring system should be
connected to the DCM1 using its POWER IN connector.
The POWER OUT connector on this CDR-1 should be
connected to the POWER IN of the next CDR-1 in the
chain, and so on until the last CDR-1 in the chain. Note
that the locations of the RJ45 connectors differ on the two

Network Terminations
Cable length and DC power considerations
The Cat 5 wiring connecting the DCM1 and CDR-1s is
essentially a data network, and as such, must be correctly
terminated. Both the DCM1 and CDR-1 are provided with
means of setting their network terminations ON or OFF.
The rule governing terminations is:
• Devices (DCM1 or CDR-1) at the ends of a cable run
must have their terminations set ON.
• All intermediate devices must have their terminations
set OFF.
• If both connectors on the same DCM1 CDR-1 PORT
(either PORT A or PORT B) are being used, the
DCM1 may be considered as an intermediate device,
and its termination should be set to OFF.
The correct termination setting is indicated for each device
in the three network examples illustrated on page 19 and
page 20. Note that in Example 1, the DCM1’s Ports A and B
are both in use, but only one connector is used on each. The
ports are thus at the ends of the chains, and their terminations
must therefore be set ON. In Example 2, all four ports are in
use, so the DCM1 is “mid-chain” with respect to both ports,
so both terminations should be set OFF.
There are two network terminations in the DCM1, one for
each port. These are set by internal jumpers J6 (Port A) and
J13 (Port B). See page 65 for details of jumper locations.
The port termination is ON when the jumper is in place.
Remove the jumper carefully, with a pair of long-nosed pliers,
to set the port termination OFF. (We suggest the jumper is
left on one of the two pins in case it is required in the future.)
On the CDR-1 and CDR-1F, the network termination is set
by jumper J2. This has two possible positions, marked MID
(termination OFF) and END (termination ON).
As far as correct data communications are concerned,
the maximum recommended cable length of the
CDR-1 network is 1 km. This gure applies either to
the total cable run between the “farthest” CDR-1 and
the DCM1 if a single daisy-chain of CDR-1s has been
employed (see Network Diagram 1, page 19), or to the
total run between the most remote CDR-1s if the DCM1
is in the “middle” of the chain (i.e., multiple daisy-chains of
CDR-1s, see Network Diagram 2, page 19). Cable runs
longer than this may work satisfactorily, but this cannot be
guaranteed. The probability of correct operation is a function
of cable length, the number of CDR-1s daisy-chained, and how
many of them are at a distance from the DCM1 close to the
maximum cable length.
IMPORTANT: The 1 km limit referred to above ONLY
applies to the digital data carried by the Cat 5 cable; a
DCM1 will NOT successfully supply DC power over
this cable length. Systems with long cable runs and/
or several CDR-1s on the same run will need external
power supplies, whose location and system connection
will depend on the topology and cable lengths involved.
The DCM1 has sufcient capacity to power eight CDR-1s
and/or CDR-1Fs (i.e., nominally one plate per zone) via the
Cat 5 connections. However, in addition to the limitation
above, one or more external PSUs will be required if any of
the following apply:
• If the system requires more than eight CDR-1s in total;
• If the “rst” CDR-1 on a daisy-chain is more than 250 m
cable run from the DCM1;
• If several CDR-1s are in a “cluster” (i.e., close together
in cable run terms) on a single daisy-chain.

The DCM1’s power supply capability can be maximised by
using as many CDR-1 PORT sockets as possible when
wiring CDR-1s.
As with data communication, the probability of satisfactory
operation is a function of DCM1-to-CDR-1 cable run, the
number of CDR-1s on each daisy-chain and the number of
CDR-1 PORT sockets used. If any CDR-1s in a system are
found to operate unreliably, it is likely that some will need
to be powered independently; as outlined above, this will
probably be the case with longer cable runs and/or several
CDR-1s on the same daisy-chain. The Cloud CPM-PSU is a
suitable external power supply, and should be connected to
the EXT POWER socket in the rear of the CDR-1. Note
that any further CDR-1s connected to the POWER OUT
connector will be powered by the external PSU.
If a third-party external PSU is to be used, it should be
rated at either 12 – 24 V DC or 9 – 17 V AC. Each CDR-1/
CDR-1F takes 50 mA at 12 V, so the current capability of any
PSU should also be checked. See page 69 for details of PSU
and current ratings.

Remote input modules from the Cloud ME-1, LE-1 and BE-1

to that described for the CDR-1 remote controls, except that
screened Cat 5 cable should be used.
Remote modules may be “daisy-chained” for wiring
convenience, providing that the following guidelines are
observed:
• ME-1 mic input modules cannot co-exist on the same
“daisy-chain” as LE-1 line input modules or BE-1
balanced input modules.
• LE-1 and BE-1 modules can co-exist on the same “daisy-
chain”.
• If more than one module is used for remote inputs
simultaneously, a mixed sum of all sources will be

DCM1 & DCM1e Installation and User Guide V1.022
Connections and wiring
Cat 5 cables used to interconnect remote input modules
carry low-level audio. To minimise noise and interference
from outside sources, only screened Cat 5 should be used. Only
use shielded RJ45 plugs when wiring this part of the system,
bonding the foil screen of the cable to the metal screening
can of the plug.
ME-1 mic input modules should be connected to the RJ45
connectors labelled MICROPHONE INPUTS on the DCM1.
LE-1 line input modules and BE-1 balanced line input modules
should be connected to the RJ45 connectors labelled
EXTENSION PORTS on the DCM1. Do not connect any
music sources to the phono sockets corresponding to the
Extension Ports being used.
The remote modules all have two RJ45 sockets, labelled
OUTPUT and LINK. The “rst” module in a daisy-chain
wiring system should be connected to the DCM1 using its
OUTPUT socket. The LINK socket on this module should be
connected to the OUTPUT of the next module in the chain,
and so on until the last module in the chain.
BE-1
Connecting Paging systems
Cloud PM Paging Microphones
The DCM1 fully supports the Cloud Paging Interface Buss
implemented across the Cloud PM range. (The Cloud Paging
Interface Buss is also used by the earlier Cloud CDPM paging
microphone range.)
Connections and wiring
The DCM1 is equipped with two RJ45 sockets for connection
of Cloud PM Series paging microphones. The sockets,
marked CDPM/PM, are labelled IN and THRU. PM paging
microphones are similarly equipped with two RJ45 sockets,
labelled IN and OUT.
If the system being installed includes one microphone, its
OUT socket should be connected to the IN socket on the
DCM1.
If the system requires more than one microphone, the
additional microphones should be “daisy-chained” together.
For example, two microphones would be wired by connecting
the OUT socket of one to the IN socket on the DCM1
as above, and then connecting the OUT socket of the next
microphone to the IN socket of the rst.

The diagram below illustrates the various methods of
connection. Note that the third example illustrates the
method of interfacing a PM16 to two DCM1s. In this case,
the CDPM/PMTHRU connector on the rst DCM1 is
connected to the IN on the second, and the PM Zone Offset
of the second would be set to +8. This would allow it to
correctly interpret commands from paging buttons 9-16 on
the PM16. See page 34for full details of how to set PM
Zone Offset.
NOTE: The CDPM/PM THRU connector is only intended
for connection of additional DCM1 units, not for additional
PM paging microphones.
Note that the single Cat 5 interconnection provides DC
power as well as audio. A full pin allocation of the Microphone
Inputs and Extension Ports can be found in the Appendix at
the end of this Guide.
The DC power consumption of the active circuitry is quite
low, and no PSU capacity problems should be experienced in
the vast majority of installations. Refer to page 69 for PSU
and current ratings.

the PM Paging Interface Buss can be found in the appendix at
the end of this manual.
PM DC power
The DCM1 can supply DC to power one PM paging
microphone. Powering of a microphone in this way is enabled
with the internal jumper J14, which is set ON as the factory
default. If the microphone connected to the DCM1’s CDPM/PMIN port is self-powered, or powered from elsewhere in
a PM network, this jumper should be removed. (We suggest
the jumper is left on one of the two pins in case it is required
in the future.)See page 69. for details of PSU and current
ratings.
Adjusting paging levels
Separate controls are available at the rear panel for setting
PM microphone sensitivity and the paging level sent to each
Zone. Full details on adjusting these can be found at page 46.
Zone paging outputs
If a PM paging microphone system is the only one being used
with a DCM1, the DCM1’s PAGING ACCESS connector
may be used to provide per-zone paging control outputs.
These can be used, for example, to activate level restoration
in 100 V line systems where local speaker volume controls
are installed. When a zone is paged from the PM system, the
control output for that zone activates (pulls down to 0 V).
PM Terminations
The rules that apply to terminating a network of CDR-1
remote control panels also applies to multiple PM paging
microphones. The DCM1 and a set of microphones should be
considered as a “daisy-chain”, and buss terminations should
be set ON in the two devices at the “ends” of the chain,
and OFF in all others. The interconnection diagram above
indicates how these rules are applied in the various possible
wiring schemes.
• In the simplest implementation of just one paging
microphone, the terminations should be set ON at both
the DCM1 and the microphone.
• If two or more microphones are daisy-chained to the
DCM1’s IN socket, terminations must be ON at the
DCM1 and the “end” microphone only.
• If two DCM1s are daisy-chained using the IN and
THRU connectors, terminations at the “ends” of the
chain should be ON. In Example 3 above, this will be at
the paging microphone and DCM1 #2. The termination
in DCM1 #1 should be set to OFF (as it is in the
“middle” of the chain).
The PAGING ACCESS connector’s default conguration
is as a zone input connector for use with third-party paging
systems. Re-assignment as an output connector is made via
the menu system. See “Congure Access Connector” on page
33 for details.
The connector is a 10-way screw-terminal type. The pinout is
given in the table below:

DCM1 & DCM1e Installation and User Guide v1.024
For many systems, the DCM1’s internal PSU will provide
27

sufcient current to activate an external relay in each zone.
Relays used in this way should have a coil voltage of 12 V DC
and draw less than 60 mA. The “Zone active” pins (2 - 9)
should be wired to one side of the level restoration relay
coils in the relevant zones. The other side of the relays should
be commoned together and connected to the +12 V pin (10).
The diagram below illustrates this.

If the level restoration relay coils draw more than 60 mA per
zone, additional intermediate relays and an external PSU must
be installed. The basic wiring scheme shown above is used,
but now the “External relays” will be the intermediate relays
instead of the restoration relays themselves. The restoration
relays are then wired via the intermediate relays’ contacts to
the external PSU, providing full electrical isolation between
the DCM1 and the external level restoration system. This is
shown in diagram a) below:

+12v10v
With all wiring schemes, attention must be paid to relay
polarity when wiring such a system, as the external relays will
almost certainly have a diode in parallel with the relay coil to
limit voltage spikes when the relay releases. Ensure that the
positive (+ve, or red) terminal of the relay coil is commoned to
the +12 V pin (pin 10) of the PAGING ACCESS connector,
or the positive terminal of an external PSU. The negative (-ve,
or black) terminal of the relay coil should always be wired to
the “Zone active” pin (2 - 9).
See page 69 for details of the DCM1’s PSU capabilities.
Third-party paging systems
The DCM1 may be integrated with any paging system which
is able to provide a microphone feed and zone selection by
contact closure.

An external PSU should also be used in systems using relays
with a coil voltage higher than 12 V. The “Zone active” pins
are rated up to 24 V, so relays of up to 24 V may be switched
directly as long as the current drawn remains below 60 mA. If
either the maximum current rating of 60 mA or the maximum
voltage rating of 24 V is exceeded, intermediate relays must be
installed as shown in diagram b).
Paging microphone input
A 3-pin screw terminal connector provides an electronicallybalanced input for an external paging microphone. This should
be connected to the external microphone using good quality
low-noise microphone cable, using the wiring shown below:

Adjusting paging levels
Separate controls are available at the rear panel for setting
microphone sensitivity and the paging level sent to each Zone.
Full details on adjusting these can be found at page 46.
Paging Access Connector
The PAGING ACCESS connector is used to activate the
paging microphone and to select the zone(s) to which it is to
be routed. It performs this function by default, though it can
be re-dened in the menu system to provide per-zone control
outputs when used with Cloud PM paging microphones (see
page 24). (Should a system require the use of both PM
and third-party paging systems, control outputs will not be
available if the connector is to be used in its “input” mode.)
Zone activation occurs when one of the “zone active” pins
(2 - 9) is shorted to 0 V (available on pin 1). Third-party paging
systems providing per-zone contact-closure on zone selection
can thus be easily interfaced by wiring the external unit to the
PAGING ACCESS connector as shown below:
Some third-party paging systems have a single “page-all”
command output, which activates all zones in use. In this case,
use the wiring scheme shown above.
Visual indication that paging is taking place is given by the
Paging Access LEDs on the front panel. The LED(s) illuminate
to conrm the Zones being paged.
Music Mute
External muting of music is available at the MUSIC MUTE
connector. National or Local Authority regulations governing
such systems may require that normal programme material
(i.e., music) should be muted in an emergency, to ensure that
any emergency messages are clearly audible.
The MUSIC MUTE input is on a 2-pin screw terminal
connector. It should be connected to the appropriate alarm
output on whichever building management system registers
the alarm (typically the Fire System). The alarm output must
be volt-free; if no such output is available, an intermediate
relay or other isolation device must be installed between the
alarm output and the Music Mute input.

PAGINGACCESS CONNECTOR

The pinout is the same as that given in page 24. Multicore
control cable should be used for the interconnection.
The Mute input can be programmed to operate on either
normally open (N/O) or normally closed (N/C) contacts via
the menu system (see page 45). The factory default setting
is N/O, thus requiring a short-circuit to be applied across the
two pins of the connector for muting to occur.
Visual indication of muting being activated is given by the
MUSIC MUTE LED on the front panel.
If the audio system itself is to be used to provide voice alarm
and/or evacuation messages, the DCM1 can be programmed
to not mute one particular line input when Music Mute is
made active. This input can be permanently connected to a
sound store or emergency evacuation microphone, so that
when activated, all inputs will be muted except the emergency
source. If this facility is being used, care should be taken to
ensure the emergency source is not madeavailable to any
zones in normal operation.

Installer Mode is selected by pressing the INSTALL button,
and entering the key code via the numeric buttons below
the display in response to the prompt Enter Key. The
key is always a 4-digit number; only digits 1 to 8 are allowed.
The factory default key can be found in the Appendix; users
are strongly urged to change the key as soon as the system is
commissioned. A time-out applies to Installer Mode; if no keys
are pressed within 45 seconds, Installer Mode will cancel and
the unit returns to User Mode.
Navigation within all the submenus is performed with the
NEXT FUNCTION button, the rotary control and the
eight numeric buttons. In general, NEXT FUNCTION
button steps through the selected submenu one function at a
DCM1 & DCM1e Installation and User Guide V1.027
time and the rotary control changes the value of the function’s
parameter. Some submenu functions also make use of the
“press” action of the rotary control. Entry to each submenu
is always at the submenu’s rst function, and each submenu
“loops round” its set of functions, with the rst reappearing
after the last.
The eight numeric buttons are used in various ways, and
may refer to the eight zones, the eight music inputs, the
four microphone inputs and so on, depending on the menu
function currently selected. With most functions, the numeric
buttons’ adjacent LEDs conrm current status.

If ME-1 remote mic input modules form part of the system,
it is likely that they will not be used all the time, and that any
mics connected to them will not necessarily need to be heard
in the same Zone(s) on every occasion. The Enable Mic Inputs menu function allows the operator to activate each of
the DCM1’s microphone inputs as required, and to determine
which Zone(s) each is routed to.
The DCM1 imposes no restrictions on mic routing, and it
is important to note that any of the four Mic Inputs may
be routed to any Zone, regardless of the physical location
within the installation of the ME-1 modules connected to a
particular input.
DCM1 & DCM1e Installation and User Guide v1.032
In practice, many installations will only ever require a
microphone input to route to the Zone where that
microphone is physically connected. The rotary control
selects the Zone; these will be displayed as Zone n unless
the Zones have been renamed, in which case the names will
be shown (see page 37 for details of renaming Zones).
Note that rotating the control “beyond” Zone 8 allows
Groups 1 to 4 to be selected as well. This permits use of
microphones to be enabled in some areas only when a Group
is in use.
The rst four numeric buttons correspond to Mic Inputs 1 to
4. Default assignment is for all Mic Inputs to be OFF. Pressing
a key enables that Mic Input for the selected Zone or Group;
a second press disables it. Note that the key LEDs indicate
current Mic Input-to-Zone/Group assignment at all times.
Because ME-1 remote mic input modules can be “daisychained”, enabling one of the DCM1’s Mic Inputs will enable
all ME-1 modules connected to that input.
No separate mic level control is available on either the DCM1
or CDR-1. Adjustment of microphone volume should be

connector as a GPIO (General-purpose Input-Output) port.
In this mode, it cannot be used in conjunction with paging
microphones for either zone selection or zone tally outputs.
When set as a GPIO port, serial data received at the RS232
INTERFACE (and/or ETHERNET INTERFACE in the
case of the DCM1e) can set individual channels logic-high
or logic-low (outputs), or the status of channels can be
interrogated and reported using RS-232 serial data (inputs).
The default allocation is with all eight channels of the
port as outputs, denoted on the lower row of the display
as GP OOOOOOOO. Turning the rotary control further
clockwise re-assigns each channel in turn as an input, e.g.,
GP IOOOOOOO, GP IIOOOOOO, and so on. Note that
channels set as inputs must always form a consecutive block
numbered ‘up’ from pin 1; likewise channels set as outputs
must always form a consecutive block numbered ‘down’
from pin 8. See page 67 for more details of how to use the
PAGING ACCESS connector as a GPIO port.
should be set in the “second” DCM1 (and left at the default
value of 0 in the “rst”). With the rst DCM1 feeding audio
to Paging Zones 1 to 8 and the second to Paging Zones 9 to
16, correct paging of the higher-numbered Zones will result.
The rotary control is used to adjust the offset value in the
range 0 (the default) to 15. Values other than 0 or 8 will
only be applicable to hybrid systems composed of a DCM1
and mixers of some other type, or when a “zone overlap”
is required for operational reasons. The numeric buttons are

DCM1s may be linked together via the CDR-1 buss to allow
systems with more than eight zones to be congured. To
maintain the freedom of CDR-1 network wiring, a CDR Zone
Offset is applied to the second (and subsequent) DCM1s, in
order that the CDR-1s are able to recognise that the system
comprises 16 (or more) zones.
Use the rotary control to set the CDR Zone Offset on the
second (and subsequent) DCM1s. The offset is in multiples
of 8.
For a 16-zone system using two DCM1s, an offset of +8 is
applied to the “second” DCM1, whose outputs feed Zones
9 to 16. The “rst” DCM1, whose outputs feed Zones 1 to
8 is left with an offset of zero. With the CDR-1 network
connected to both DCM1s, all 16 zones will now be available
to each CDR-1 for assignment.
CDR Zone Offset need not be altered from zero if each
DCM1 in a multiple system has its own independent “daisy-
chains” of CDR-1s, and there is no CDR link between the
units.
The purpose of the PM Zone Offset menu function is to
permit Cloud PM and CDPM paging microphones to address
more than 8 zones.
Cloud PM and CDPM systems can address up to 16 Zones
(model-dependent). To permit paging of Zones 9 and higher

The threshold for priority activation is -24 dB below the
input’s nominal level.
The rotary control selects the Zone in which the priority is
to be set (displayed by name if they have been renamed). Note
that rotating the control “beyond” Zone 8 allows Groups 1

that Music Input as the Priority Line Input for the currentlydisplayed Zone or Group; a second press de-assigns it.
The choice of Priority Line Input for a Zone/Group can be
made from any of the eight Music sources, including any which
have been deliberately disabled for that Zone/Group in the

signal to be more readily heard; this process is often called
“ducking”. The Mic Pri Sel menu function congures the
DCM1 to do this.
The rotary control selects the Zone in which Microphone
Priority is to be set (displayed by name if they have been
renamed). Note that rotating the control “beyond” Zone
8 allows Groups 1 to 4 to be selected as well to permit
assignment of a priority microphone for each Group as well
as each Zone.
The rst four numeric buttons correspond to the four

An external emergency mute applied at the Music Mute rear
connector will normally mute all eight Music Inputs and all
four Microphone Inputs. Paging remains operative. Some
installations may require that one input is reserved as an
emergency audio input, for a Fireman’s Mic or Emergency
Evacuation message. The Emergency Source menu function
determines which input this will be.
Any input may be nominated as the emergency source. Either
a Line or Mic Input may be chosen, making it possible to
interface either microphones directly or line-level devices
such as sound stores.

Four Groups can be dened, with no restriction on Zone
membership. A Zone may be a member of more than one
Group, but if so, only one Group which includes that Zone
may be enabled at a time. Once set up, a Group may be
enabled or disabled at will by the user, via the Group Enable
function of the Groups Menu.
The rotary control selects the Group to have Zones assigned.
The Groups will be displayed as Group 1 to Group 4
unless they have been renamed, in which case the names will
be displayed.
The eight numeric buttons correspond to the eight Zones;
they select Zone membership of the currently-selected
Group. Press the numeric buttons to select or deselect Zones
from the Group. Conrmation of Group membership is given
by the LEDs above the numeric buttons.
Other DCM1 adjustments
In addition to the settings and adjustments made via the menu
system, the DCM1 has a number of adjustments which are
made elsewhere. Most are concerned with paging and are
located on the rear panel; they are intended to be set at the
time of installation and not subsequently altered by the user.
All the controls are recessed trimpot types, and should be
turned carefully with a trimming tool. Attempting to adjust
them with an oversize screwdriver will cause damage.
Paging mic gain
This control sets the sensitivity of the Paging Mic Input, for
third-party paging systems. The gain range is 10 dB to 50 dB;
installers should check the mic signal level available from the
paging system, and initially set this control accordingly.
Its setting will affect the paging mic level in all zones being
paged.
PM Series paging microphone gain
It should be noted that if a system uses multiple DCM1s,
Groups can only comprise Zones within each DCM1; Zones
from different DCM1s cannot be combined.
UTILITY
Group Member may be dened from the Utility Tool
by clicking the OUTPUTS tab, selecting the Group in
the left-hand drop-down list (below Zone 8), and then
clicking the checkboxes for the relevant Zones in
the Group Members area. Click Send Output to
transmit the new setting.
DCM1 & DCM1e Installation and User Guide v1.046
This control sets the mic level for a PM Series (or CDPM)
paging system interfaced to the DCM1. Like the Paging mic
level (above), its setting affects all zones being paged, and its
adjustment is made in the same way. The gain range is ±10 dB.
Paging mic EQ
HF and LF EQ controls for paging mics are provided. These
may be adjusted to reduce any extraneous noise in the vicinity
of the paging mic, or to compensate for any undesirable
colouration of the mic itself. The controls are adjacent to
the (third-party) Paging Mic Input, but they affect both
microphones connected to the Paging Mic Input and mic
signals from a PM Series paging mic (or CDPM) connected to
the CDPM/PM ports.
The HF control provides up to 10 dB cut or boost above
5 kHz, and the LF control 10 dB cut or boost below 100 Hz.
Again, these controls should be adjusted using a test message,
ideally to the zone where the DCM1 is installed so that the
effect of the adjustment can be heard by the person making it.
As the controls affect both the CDPM/PM ports and thirdparty paging mic inputs, a degree of compromise may be
necessary if a system requires both inputs to be used.

message should be made by the person who will normally
use the microphone, as some people speak much louder
than others.
6. Repeat Steps 2 to 5 for the other Zones.
7. Repeat Step 1 for the other music sources.
Display Contrast adjustment
The display should be easily readable in most normal situations.
If it is necessary to alter the display contrast to improve
readability under extreme ambient lighting conditions, remove
the top cover (8 screws) and locate the trimpot at the lefthand end of the PCB mounted directly behind the front panel.
This can be adjusted as required. Replace the cover using the
same screws.
CDR-1 Series Remote Control Plates
Most audio systems based around the DCM1 will include one
or more CDR-1 Series remote control plates to permit in-
zone selection of music source and level.
Zone Paging Levels
Each zone output connector has an adjacent preset control
which sets the volume for paging in that Zone. The PAGING
LEVEL adjustment for a Zone is completely independent of
the music level adjustment for that Zone, the latter being set
by the user.
Setting up levels for best performance
To optimise signal levels through the DCM1 and obtain
the best signal-to-noise performance, we recommend the
following procedure is followed for adjusting music and paging
levels. (Numbers in squares refer to the rear panel diagram
on page 15.)
1. Choose a suitable music source, and set the Input Gain
of its input to 0 dB, via the Music menu in Installer mode.
2. Route this music source to a convenient Zone, and adjust
the Level in this Zone to 0 dB (i.e., maximum), again via
the Music Menu.
An overview of the CDR-1 can be found on page 7 and
notes on installation and wiring at page 19.
User Operation
The backlight in the CDR-1’s display automatically times-out
after a few seconds (the actual time is programmable) to
minimise power consumption. The display is “woken up” by
pressing the ZONE button, and the unit conrms the Zone it
has been assigned to, either as Zone n, or by name if the
zones have been renamed (see diag i) below).

+ or – buttons are pressed. The i and h buttons can now be
used to scroll through the inputs available to the zone. Only
those inputs which have been enabled in the DCM1 menu
system at ROUTING > Input Enable will be displayed. The + and – buttons adjust the volume.
This sequence is modied if the Zone has been dened as a
member of a Group. If so, the next press of ZONE after the
panel “wakes-up” displays the Engineer Mode Enter Key
screen. This gives the user the option of entering the key, after
which the display will show the Group Select screen.

To activate Installer Mode:
If the CDR-1 has already been installed, remove it from its back
box and disconnect the power supply, either by unplugging the
POWER IN RJ45 connector if the CDR-1 is being powered
from elsewhere in the system, or by unplugging the local PSU
if it is being powered locally. Move the jumper J1 as shown
below.

turn (in the same manner as the NEXT FUNCTION button
in the DCM1’s menu system). The two User Mode screens
are also presented before the menu loops around.
The i, h , + and – buttons are used to adjust the parameters
in each function.
Group Select

a member. If the Zone is only a member of one Group, the
lower row of the display will toggle between Zone n and
Group m where n and m are the Zone and Group numbers
respectively. If the Zone belongs to more than one Group, the
additional Groups will be displayed in turn; pressing ZONE
when a Group is displayed will enable that Group; pressing
ZONE when the Zone is displayed will disable a Group and
return to normal operation.
Engineer Mode
The CDR-1 may be placed in Engineer Mode to allow EQ
adjustment to be performed from within the zone itself.
Engineer Mode is fully described on page 35.
Note that the display time-out is disabled in Installer Mode.
Remember to remove the power from the CDR-1 and put J1
back to its “normal” setting after conguration is complete.
Installer Mode
Installation of a CDR-1 necessitates the activation of a further
mode, Installer Mode, to allow some additional parameters
to be set, including zone assignment. (NOTE: CDR-1 Installer
Mode, described here, is not to be confused with DCM1
Installer Mode.)

Display adjustments
Set Key
The rst menu function allows adjustment of the display
contrast and backlight to suit different ambient lighting
conditions. The i and h buttons adjust the backlight level and
the + and – buttons adjust the contrast.
Inactivity Time
This function sets the display time-out. Use the + and – buttons
to set a value of between zero and 30 s the default is 10 s.
The display backlight will turn off after this delay, following the
last CDR-1 button press. If the delay is set to zero, or jumper
J1 is left in the Installer Mode position, the backlight remains
on at all times.
Assign Zone
This assigns the CDR-1 to a particular Zone. The + and –
buttons scroll through the eight Zones; note in this function
they are displayed as Zone n even if they have been
renamed. The default setting is Zone 1.
Once a CDR-1 has been assigned to a Zone with the Assign Zone function, all operations on that CDR-1 will affect all the
speakers being driven from that Zone Output.
This lets the installer set the 4-character key code used
to access CDR-1 Engineer Mode, once the CDR-1(s) in
a particular Zone have been enabled in the DCM1 System
Menu (with the CDR Zone Setup function).
The bottom row of the LCD rst displays the current key;
the factory default is <<>>. Any permutation of the four
characters <, >, + and – may be used (except four identical
characters); as soon as any of the four buttons is pressed, the
existing key is erased. The key must have 4 characters.
If a key consisting of four identical characters is entered, the
bottom line of the display will show None. This overrides the
requirement for a key to be entered to use Engineer Mode,
and the EQ adjustment and Group Selects screens will be
available to the User as soon as the Zone is enabled in CDR Zone Enable.
Combining Engineer and Installer Modes
It may be convenient to enable CDR-1 Engineer Mode as each
CDR-1 is being installed, as this will allow the Zone EQ to
be set at the same time. When Engineer Mode is enabled,
the three EQ adjustment functions are presented in sequence
after the User functions, as shown in the owchart on the
previous page.
It is possible for more than one CDR-1 to be assigned to the
same Zone in a system. This will be useful in some situations,
such as in large rooms. All CDR-1s assigned to the same Zone
will be able to control operation in that Zone.
DCM1 & DCM1e Installation and User Guide v1.050
Section 4: Software control
Controlling the DCM1e from the
browser interface
The DCM1e has a server function, which makes control pages
available to a browser running on a device connected to the
DCM1e’s Ethernet port. This permits simple and elegant
real-time control from any convenient device on the same
network.
Conguring the network
NOTE: This section of the manual is intended for those
with a working understanding of basic computer network
conguration and the terminology involved.
The Ethernet connection to the DCM1e can be simplied
by the use of the Cloud Ethernet Discovery Tool. This can
be downloaded from www.cloud.co.uk; navigate to ‘Products’
and select ‘DCM1e Ethernet Digital Control Mixer’; the Tool
is available for download in the ‘Technical Notes’ panel. The
Discovery Tool is in the form of an executable JAR le, and
will run on Linux, Windows® or Mac® systems within a Java
Runtime Environment (available from www.java.com). Save it
in any convenient location.
Connect an Ethernet cable between the socket marked
ETHERNET INTERFACE on the DCM1e rear panel and a
spare port on your network switch. Connect your device to
the same network.
Run the Discovery Tool, this will open the window shown
below, which should contain an entry with the host name
DCM1-ANON.
Click the menu icon
Cloud banner and now select Cong, followed by Network.
We recommend that the DCM1e should be set with a static
IP address (i.e., DHCP disabled) or uses a reserved address
on your routing hardware. It will then have a xed IP address
on the network for other devices to browse to. Ensure that a
suitable IP address is reserved on the network to which you
intend to connect the device. If the DCM1e changes IP address,
client security settings will not be preserved. (Installers may
need to consult the IT Manager of the installation premises
for guidance.)
at the right hand end of the blue
Security
Each new client using the network needs the Installer PIN to
allow access and conguration of the interface. Each client’s
security settings - except for the PINs - are stored on the
client device itself.Clearing browser history will cause the
device to be reset, and will become a “new” client.The installer
PIN is then required to recongure the device correctly.
Security PINs for Installer and Power privileges are the same
for all clients.The Installer PIN is the same PIN that is used to
access additional conguration functions from the DCM1e’s
front panel. Installer and Power PINs can be changed using the
web interface.
Single-click on the DCM1-ANON entry. This should open your
default browser and make the DCM1e’s server pages visible.
The rst page to be displayed on initial connection will be
the PIN entry page; enter the Installer PIN to authorise the
device. When this has been done, you will see the Security
Settings page for the device. (This sequence only occurs on
initial connection of a new device or browser.)
The factory default PINS are:
• Installer = 1234
• Power = 5678
If the DCM1e changes its IP address, all clients will be treated
as new clients.

Browser compatibility
The DCM1e server pages use HTML5 and CSS3, which are
only implemented by recent browser versions. The HTML
features used by the DCM1e are listed below:
• Storage
• Localstorage
• Sessionstorage
• Forms
• Input type=number
• Elements
• Section elements
• Hidden attribute
The easiest way of checking your browser’s compatibility is
to go to html5test.com, and carry out the test available there.
the Internet Explorer Help options.
• I can’t swipe/drag the level controls
These controls are button activated. There is no drag or
swipe feature.
• I have congured my network settings, but it still
continues to use DHCP
Check the Power On Mode from the front panel of
the DCM1e. If this is set to “Factory”, user congured
settings will be ignored.
• I can’t remember the settings for my DCM1e!!
How do I connect now?
Adjust the Power On Mode to Factory from the front
panel of the DCM1e. This will then revert the network
settings to their defaults until this setting is changed or
new network settings are applied.
Further FAQs are available at www.cloud.co.uk.
Quick Troubleshoot
• I can’t download or run the Discovery application.
Download an IP scanning application (such as ezNetScan
or Fing) on to your device. Run the scanning application.
DCM1e hardware will show with a Microchip Technology
Inc. MAC address registration and a MAC address starting
with 00:04:A3... or 00:1E:C0.... Enter the corresponding
IP address in to your browser address bar.
• I want to connect to the DCM1e directly from a
PC or Mac.
The DCM1e should rst be connected to a DHCP
serving router to then congure a static IP address for
direct communication.
• I can’t browse to the DCM1e on my network.
Check all settings on the client device to ensure that you
are on the same network.
Run the Discovery Tool. The DCM1e may change IP
address if DHCP is enabled.
If the entry in your Discovery Tool declares the unit with
a - Bootload sufx, the unit is expecting a rmware
update. You can exit this mode in two ways:
Initial Login – User Mode
Once the client has been authorised, the rst page to be
displayed will be that shown below. Note that the default
login will always be as User; this means the DCM1e is in User
Mode and only User Mode menu functions will be available.
Level and Line Input controls for Zone 1 are displayed.
Use the ‘-‘ and ‘+’ controls to alter the settings. Any renamed
inputs will be correctly displayed in the Line Input eld.
To control music level and source in different Zone or Group,
select the Menu icon
will change the display to that below:

browser interface will “time-out” and return to User
Mode after a period (approx. one minute) if no buttons
are pressed
Selecting the Menu icon now shows that three further options
are available: Grouping, Inputs and Cong.
NOTE: The following descriptions of Installer Mode
options assume that the default factory access settings on
the Security Page have not been changed. As explained
below (see Cong menu, Security), access to other unit
congurations and settings can be dened by an Installer on
a three-level basis – User, Power and Installer. The factory
default settings allow a User to control music source and level
only, and an Installer to have access to all other functions.
Grouping
This menu allows Groups to be dened and enabled/disabled.
Select Grouping and then select the Group to be
congured (Group 1 to Group 4). The display changes
to the Group n Page:
DCM1 & DCM1e Installation and User Guide v1.053
The default state is for all Groups to be unassigned and
disabled. To assign a Zone to the selected Group, tap/click on
the red cross; it will turn into a green tick. Similarly, to enable
the Group, tap/click on the red cross against the Group name.
The functions on this page correspond to the menu functions
Group Enable and Dene Groups respectively. See page

Cong
This menu has eight options, allowing access to various
DCM1e System and other conguration functions.
Inputs
This menu allows denition of which Line Inputs are available
to each Zone and/or Group, and enabling/disabling of Mic
Inputs.
Select Inputs and then the Zone to be congured (Zone 1 to Zone 8). If any Groups have been dened and enabled,
the Zones comprising a Group will not be listed individually,
but the enabled Group will be added to the list. The display

This function is specic to the browser and gives the installer
much greater control over how the DCM1e is congured in
terms of who has access to which controls than is possible
from the DCM1e itself. As described elsewhere in this manual,
the standard hardware security settings provide two Modes:
User and Installer.
To make a Line Input unavailable to the selected Zone/Group,
tap/click the green tick against its name; it will turn into a red
cross. The default state is for all Line Inputs to be available
to every Zone and Group. This function corresponds to the
menu function Input Enable; see page 33 for full details.
To activate a Mic Input for the selected Zone/Group, tap/
click the red cross against its name. The default state is for all
Mic Inputs to be Off in all Zones and Groups. This function
corresponds to the menu function Enable Mic Inputs; see page

DCM1 & DCM1e Installation and User Guide v1.054
• User Mode allows immediate control of music level,
music source selection and enabling/disabling of any
Groups which have been dened.
• Installer Mode allows access to all other menu functions.
The DCM1e browser interface allows for a third,
“intermediate” level of operator – “Power”. The DCM1e’s
functions are presented as a set of categories, and the
installer can assign an access level – User, Power or Installer
– independently to each category. This gives the facility in
which the DCM1e is installed improved control over which
staff members can access which audio and system functions.
For example, in a typical bar or hotel installation, bar staff
might only have control over music source and level, but the
Duty Manager, with Power privileges, would additionally be
able to congure Groups and Mic Inputs. Remaining system
congurations would remain with the installer. A user with
Power privileges has a 4-digit PIN; this should not be the same
PIN that is used to access Installer Mode. The factory default
Power PIN is 5678.
Tap/click on the arrowheads to alter the access privileges for
any of the categories. Using the example above, if a Power
User needs to be able to congure Groups and enable Mic
inputs, set Group Members and Mic Input Enable
to Power.
The table below summarises the functions an operator is able
to congure if he/she has the appropriate privileges:
This function is specic to browser control; it allows some
Zones or Groups to be removed from other control pages.
For example, it may be desirable to restrict control of facilities
in some Zones, making control only available through the
DCM1e front panel or any installed CDR-1 plates.
The default setting for full access; to disallow control of a
Zone or Group via the browser interface, tap/click the green
tick to turn it into a red cross. The Zone or Group will now
not appear in the lists of Zones available for control.

UTILITY
Conguring the DCM1 with the
DCM1 Utility Tool
Almost all DCM1 congurations and settings may be made
remotely using serial commands through the rear panel
RS232 INTERFACE connector*. A simple software
application, the DCM1 Utility Tool, uses this feature to permit
the DCM1 to be congured remotely on a laptop, tablet or
other Windows-compatible device. This allows an installation
engineer to pre-congure a DCM1 off-site, and then upload
the unit’s core conguration and settings from the device
with a single mouse click. Further adjustments to individual
settings may be made in a similar manner.
*A version of the Utility Tool which can use an
Ethernet connection between the device running the Tool and
a DCM1e as well as an RS-232 serial link will be available
during 2014. This will allow devices without either serial
or USB ports to use the Tool, provided they have network
capability. Please check www.cloud.co.uk for details.
from the options list on the right; download the two Utility
Tool les – the application itself is a .zip le, the other is a
.pdf ReadMe le. Save the les to a suitable location.
The ReadMe le gives information about DCM1 OS
compatibility; see page 39 for details of how to check which
rmware version is installed.
Navigate to the .zip le, and unpack it. The zip contains a
single .exe le, DCM1Utility Tool Vn_m.exe (where
n.m is the version number). Save this le to any convenient
location.
Connecting to the DCM1
Serial communication between the Utility Tool and a DCM1
uses one of the device’s Comms ports. If the device does not
have a 9-pin serial port, obtain a USB to RS-232 convertor
and connect to a USB port. Use a standard, male-to-female,
9-pin serial cable to between either the native serial port or
the USB convertor and the DCM1’s RS232 INTERFACE
connector. See page 66 for further information regarding
the interface and cable.
Installing the Utility Tool
The DCM1 Utility Tool may be used with either the DCM1 or
DCM1e. At the time of publication, the application has been
tested with Windows XP (+SP3), Windows Vista, Windows
7 and Windows 8; please check www.cloud.co.uk for any
updates to this list. Note that there is no Mac version.
The Utility Tool may be downloaded free of charge from the
Cloud website, www.cloud.co.uk. From the Home page, select
Products, then the DCM1 or DCM1e. Select Technical Notes
the DCM1, please check your device’s port settings.

Larger systems – cascading DCM1s
If an installation requires more than eight Zones, multiple
DCM1s may be interconnected to provide a system with
a larger number of outputs. For example, two DCM1s will
provide 16 zones, three DCM1s 24 zones, and so on.

System Interconnections
In order to provide a transparent system which can be
operated with the same ease as one with a single DCM1,
interconnections between multiple DCM1s must follow a
few rules. The range of possibilities afforded by using multiple
DCM1s is extremely large, and each installation will be guided
by the user’s requirements and the building layout.
The example given is for a simple 16-zone system comprising
2 DCM1s, with a CDR-1 in each of the 16 zones. The block
diagram below shows how the various inputs are – or are
not – interconnected. All possible connections have been
depicted, though it is recognised that most systems will not
use all of a DCM1’s connectivity simultaneously.

DCM1 & DCM1e Installation and User Guide V1.062
Line Inputs
It will generally be possible to directly parallel the outputs
of music sources to the Line Inputs of several DCM1s using
suitable adaptors, splitter cables or junction boxes. Installers
should satisfy themselves that the output of each music
source is not reduced in level or frequency response by such
a multiple connection; for most equipment, ve is the upper
limit of unbalanced inputs which can be paralleled in this way.
A more satisfactory solution is to use a stereo audio
distribution amplier (DA) for each source, with as many
outputs as the number of DCM1s being fed. Connect the
amplier input to the source and the outputs to the same-
numbered input of each DCM1.
Extension Ports
The Extension Ports cannot be paralleled, but this is unlikely
to be a system requirement as the use of remote line input
modules (LE-1s and BE-1s) will be limited to the Zones
in which they are located. They will thus be wired to the
Extension Ports on the DCM1 feeding those Zones, and not
to any other.
Mic Inputs
ME-1 remote mic input modules cannot be paralleled to
multiple DCM1s, but their use will also be limited to the
Zones where they are installed. Any ME-1s in a system should
be connected to the Mic Inputs of the DCM1 feeding the
Zones where they are located.
Zone Outputs
Each DCM1’s Zone outputs will feed a separate set of power
ampliers for those Zones. Thus in the example shown, DCM1
#1’s outputs will feed the ampliers driving the loudspeakers
located in Zones 1 to 8, while DCM1 #2’s outputs will feed
the ampliers driving the loudspeakers located in Zones 9 to
16.
in DCM1 #1 and ON in DCM1 #2. The PORT B termination
would be set ON in DCM1 #1, and the corresponding
jumper setting in DCM1 #2 is unimportant. It is important to
recognise that the CDR-1s on each of the two chains in this
example can be anywhere in the building, in any Zones.
So that any CDR-1 in this system is assignable to any of the
16 Zones, the CDR Zone Offset function must be set to +8
on DCM1 #2. This is set in the menu system; see page 34
for full details. With this setting made and the two DCM1s
interconnected as shown, all CDR-1s in the system will offer
all 16 Zones in their Assign Zone function when CDR-1
Installer Mode is activated (see page 48).
The restriction placed on CDR-1 network wiring by multiple
DCM1s results from the necessity of using one CDR-1 Port
on DCM1 #1 to route the network through to DCM1 #2. In
the example shown, the building network wiring would be
limited to six chains, three on each DCM1.
It should be recognised that neither a CDR-1 network
interconnection between multiple DCM1s, nor the use of
CDR Offsets may be necessary at all, if a network topology
can be installed which limits the CDR-1s on any one chain to
Zones which are being controlled by a single DCM1. Thus in
the example, if the CDR-1s in Zones 1 to 8 were on a single
chain, and those in Zones 9 to 16 on another, the rst could
be connected only to DCM1 #1 and the second to DCM1 #2,
providing a simpler wiring system.
When planning the CDR-1 network, the DC power supply
capability of each DCM1 must also be taken into account. As
each DCM1 can only supply sufcient current to operate 8
CDR-1s, it may be that an external PSU(s) will be required at
some position(s) in the chain(s) when multiple DCM1s are
being used. Although interconnecting two DCM1s as shown
in the example permits full access to all zones in operation,
it does not mean that 16 CDR-1s can be powered by using
two DCM1s. If the system in the example was connected to
a single chain of 16 CDR-1s (with Port B being ignored), an
external PSU would need to be added to the chain at the
CDR-1 #9, to power the “farthest” 8 CDR-1s.
PM Series paging mics
CDR-1s
Using more than one DCM1 in a system does not greatly
compromise the exibility of CDR-1 network wiring. The
Installation section of this manual gives examples of the
various wiring topologies which may be adopted (see xxx);
that used in any particular installation will be dictated by
building layout and wiring convenience.
The example above shows two chains of CDR-1s – called
‘network A’ and ‘network B’ for reference, connected to
two of the CDR-1 Ports on DCM1 #1, one to PORT A,
the other PORT B. Only one CDR-1 interconnection is
needed between multiple DCM1s. Either of DCM1 #1’s two
remaining ports may be used to connect the CDR network
to DCM1 #2, and any of DCM1 #2’s four ports may be used.
In the diagram, the second PORT A socket on DCM1 #1 is
connected to one of the PORT A sockets on DCM1 #2. In
this case, the PORT A CDR-1 termination would be set OFF
In order for a PM (or CDPM) system to access all 16 Zones,
the two DCM1s should be interconnected as shown, with
the CDPM THRU connector of DCM1 #1 connected to
the CDPM IN of #2. The CDPM termination in DCM-1 #1
should be set OFF, and that in DCM1 #2 should be set ON.
See also page 23.
Third-party paging system
The microphone of a third-party paging system will need to
address all Zones, so it must be connected to the PAGING MICROPHONE INPUT of both DCM1s. Paralleling a
microphone signal is not recommended, and a microphone
splitter, of either active or passive type, should be used as
shown.
Interfacing a third-party paging system to a 16-zone system
will require separate connections to the PAGING ACCESS
DCM1 & DCM1e Installation and User Guide V1.063
connectors of the two DCM1s. The paging commands for
Zones 1 to 8 should be wired to the PAGING ACCESS
connector of DCM1 #1, and those for Zones 9 to 16 to that
of DCM1 #2. The general wiring procedures described at
page 26 should be followed.
Music Mute Input
The MUSIC MUTE inputs on the two DCM1s can be
paralleled together, though this is not ideal. A preferred
solution, if available, is to use a separate set of emergency
system contacts for each DCM1 making up the system.
RS-232 Control
If the DCM1s are to be controlled via RS-232 by an
external control system, the two DCM1s should be treated
independently. Connect each DCM1’s RS232 INTERFACE
to a separate RS2-32 port on the system controller. The
controller should be programmed to address each unit
independently.
Ethernet interface
Two DCM1e’s should each have their ETHERNET
INTERFACE port connected to two separate ports on
the network switch. Ensure that the units have different IP
addresses. Each unit can then be controlled via the browser
interface independently.

Serial Control
The DCM1 is equipped with a bi-directional RS-232 serial
interface.
As a receiver, the interface permits external control of almost
every DCM1 function, parameter and setting. The DCM1
appears as a DCE (Data Communications Equipment) device
to controlling equipment.
The DCM1e is additionally able to receive the same serial
commands in the form of TCP/IP data via the ETHERNET INTERFACE connector.

NOTE: A future rmware release for the DCM1e
will permit the RS-232 interface to be programmed
to transmit serial data to external equipment, thus
additionally acting as an Ethernet to RS-232 bridge for
equipment which does not have Ethernet capability.
The full RS-232 protocol is beyond the scope of this manual,
but can be downloaded from www.cloud.co.uk.
This section provides only details of the port parameters and
an abridged serial command list, which comprises the normal
User controls.

The rear panel RS232 INTERFACE connector is a D9F.
The pinout is shown in the table:

Not all control systems interpret “Tx” and “Rx” the same
way, and the installer should check whether pins 2 and 3 (and
7 and 8 if used) should be “crossed” within the cable. The
installer should also check whether the control system being
used requires RS-232 ow control to be implemented, and
if so, whether hardware control or software control is used.
Hardware ow control (sometimes called RTS/CTS) requires
pins 7 and 8 (at the DCM1 end) to be connected.

2. Zone Levels:
Levels can either be set to an absolute value (in dBs), or
increased/decreased by a specied number of dBs.
For absolute levels, the number of dBs corresponds to
attenuation rather than gain, thus 0 dB is maximum level and
at -62 dB the zone is muted. The values of y and m in the
general format are the Zone No. (1 to 8) and the attenuation
level in dBs (0 to 62) respectively.
To alter the Zone level by a specied amount, the additional
ASCII characters ‘U’ (up) or ‘D’ (down) are added to the
string. The values of y, p and q in the general format are the
Zone No. (1 to 8), the level increase in dBs (0 to 62), or
the level decrease in dBs (0 to 62) respectively. A command
to increment the level by a number of dBs greater than the
current attenuation will set the level to maximum. Similarly, a
command to decrement the level by a number of dBs greater
than (62 minus the current attenuation) will mute the Zone
output.

4 . Enable/Release Paging
RS-232 control of paging applies only to third-party paging
systems connected to the Paging Mic Input.
This command differs from the others in that the value of y
in the general format is in the form of an 8-character mask
of ASCII “X’s” (select) and “O’s” (don’t select), with the
character position in the mask denoting the Zone number.
EXAMPLECOMMAND
Enable
paging to
Zone 2
Enable

Note that it is not strictly necessary to transmit the “O”
character (4Fh) for channel numbers above the highest being
paged. Thus <PM,PAOX/> (ASCII) would sufce in the rst
example above, and <PM,PAOOOXXXX/> in the second.
However, the full eight characters are shown in the table for
completeness, with the extra characters in brackets in the
hex version.
Conguring the Paging Access
Connector as a GPIO port
By default, the rear panel PAGING ACCESS connector
is congured to select the zones to which paging will be
routed when the DCM1 is used with a paging system other
than a Cloud PM (which use the digital PM paging interface).
If this functionality is not required, the connector may be
recongured to provide per-zone output tallies; see page
33 and page 23 for full details.
A third option is to use the PAGING ACCESS connector
as an 8-way GPIO (General Purpose Input/Output) port. In
this mode, any of the eight “zone” pins may be congured
as a logic input or output, and they will no longer have any
direct relevance to the DCM1’s paging functions. The main
use of this mode is in conjunction with an external control
system (e.g., Crestron, AMX, etc.). The control system can be
programmed to interrogate the DCM1 to evaluate the logic
status of input pins, or to set the logic status of output pins.
The commands will be via RS-232 strings sent to the RS232 INTERFACE, or in the case of the DCM1e, via TCP/IP serial
commands to the ETHERNET INTERFACE.
DCM1 & DCM1e Installation and User Guide v1.067
The Congure Access Connector menu function permits
a slightly restricted set of I/O congurations of the eight pins:
inputs and outputs must be in consecutive “blocks”, e.g., pins
1 to 4 may be inputs with pins 5 to 8 as outputs. However,
using serial commands allows any combination of inputs and
outputs (up to a total of eight) to be set up. Examples are
given below.
Inputs:
In Input mode, the logic level present at a pin will be evaluated
as “high” (>2.55 V) or “low” (<0.75 V), and logic “active” =
“low”. The most common use of the GPIO port in Input
mode is to connect a pin to an external SPST push-button or
other type of N/O switch, with 0 V being applied to the other
contact. In Input mode, the pins are pulled-up internally to
+12 V, so an external switch closure will register as a low level
on interrogation, and this is interpreted as “active”.
Outputs:
In Output mode, the pins may be assigned to be “high”
(nominally +12 V) or low (nominally 0 V). External equipment
requiring a logic input may be connected to output pins,
provided the inputs are rated at not more than 24 V and do
not draw more than 60 mA.
Using Serial commands with the GPIO port:
2. Congure as GPIO port
The value of x in the general format command
<SY.AC,Dxm/> is again either ASCII “I” or “O”, with m
dening a number of pins on the connector to be GPI(s) or
GPO(s) respectively (where 1 ≤ m ≤ 8). In this mode, note
that pins set as inputs will always form a consecutive block
numbered ‘up’ from pin 1; likewise pins set as outputs will
always form a consecutive block numbered ‘down’ from pin
8. Thus in the third example below, pins 1 to 3 will be set
as GPIs, while pins 4 to 8 will remain as GPOs. A command
setting a pin to the same I/O state as its current state will
have no effect.
3. Set GPOs active
Once pins have been dened as outputs in GPIO mode, each
may be set “active” or reset “inactive” at will, using the general
format command <SY.AC,BSy/>. Here, y is an 8-bit string
consisting of either ASCII “X”s or “O”s. An “X” will set an
output “active”, and its in-string position refers to the the pin
number, as shown in fourth example below.

PSU capability
RJ45 pinout
In addition to supplying the DCM1’s internal circuitry, the PSU
has the capacity to power some additional items which may
form part of a complete system. These include CDR-1 remote
control panels, remote mic and line input modules, PM Series
paging microphones and any level restoration relays which
may be connected at the Paging Access Connector in Output
mode.
The maximum current capacity of the PSU available for
powering external items is 470 mA on each of the +12 V
and -12 V rails. This should be used as the guide gure when
calculating whether any external PSUs will be required in a
system.
Current consumption of the various items is listed in the
table below.

*Max current consumption during message recall
The installer should ensure that the total current drawn by all
the external items in a system does not exceed 470 mA. If the
PAGING ACCESS connector is being used as an output to
operate level restoration relays (either directly or indirectly
– see page 23), the current taken by the relay coils must
also be taken into account. The open-collector outputs at this
connector are limited to 60 mA per zone.
If the total current required by external items does exceed
470 mA on either rail, additional PSUs will need to be added
to the system. The Cloud CPM-PSU is suitable for powering
CDR-1 remote control panels and PM Series microphones
and can be readily interfaced with the respective networks.

DCM1 & DCM1e Installation and User Guide v1.069
Fitting loudspeaker EQ cards
Each output channel of a DCM1 may be optimised for use with
certain makes and models of installed sound loudspeakers; a
single-channel equalisation module may be tted to as many
Zone outputs as necessary.
To install equalisation modules, rst remove the top cover
from the DCM1 (8 screws). The modules plug into the white
12-pin connectors on the upper PCB. Note the header
connectors on the PCB have two notches on one side only;
these engage with lugs on the equalisation module’s mating
connector to ensure correct orientation.
details of recovery procedure (should bootloader be entered
accidentally) and how to change the baud rate.
The new rmware can now be transferred. Should the
transfer fail, turn the DCM1 off, and hold the NEXT button
down while powering it back on again. Go immediately to the
Firmware Update menu function, and turn the bootloader
off.
Full instructions on how to perform an update will be
provided with the update le, including details of the PC
software application for handling the le transfer.
After tting equalisation modules to any channel(s), the
corresponding module bypass jumper(s) must be removed in
order for the module to function. These are J25 to J34; see the
Appendix section “PCB jumper locations and settings” page
65 for full details. Replace the top cover with the original
screws after tting.
Firmware updates
This section describes the process for upgrading the DCM1’s
rmware.
As a responsible manufacturer, Cloud Electronics adopt
a policy of continuous product development. As with all
software-based products, it may be desirable from time to
time to update the rmware in the DCM1 with a more recent
version. Update les are available as downloads from the
Cloud website www.cloud.co.uk. Alternatively, please contact
your Cloud dealer or distributor.
DCM1 only:
The new rmware is transferred from a PC to the DCM1 via
the latter’s RS-232 port. The PC used for the transfer should
either have a 9-pin COM port or a USB-to-COM convertor
should be used. A straight-through, fully-populated D9 cable
should be used. The default baud rate for transfer is 115200
baud, but this can be altered by changing the positions of
jumpers J10 & J11 (see page 65 for jumper locations). The
table below gives the alternative baud rates available:
DCM1e only:

EMC considerations
Cloud DCM1 fully conforms to the relevant electromagnetic
compatibility (EMC) standards and is technically well behaved;
you should experience no operational problems, and under
normal circumstances, no special precautions need to be taken.
If the unit is to be installed in close proximity to potential
sources of RF disturbance such as high power transmitting
stations, radar facilities, etc., the performance of the mixer
may be reduced; we suggest that particular attention is paid
to screening of audio cables – especially microphone cables,
and that all cables are kept as short as possible.
