Packaging
The shipping carton and packaging materials
provide protection for the module during transit.
Please retain the shipping cartons in case
subsequent shipping of the product becomes
necessary.
Product Description
The C AD 3320 D (European version) / C AD 3321 D
(US version) is a high quality dual channel analog
audio to AES converter designed primarily for
broadcast and professional applications.
The Module accepts balanced analog audio
inputs and converts these to 24 bit AES digital
streams. Sampling rates of 32KHz, 44.1KHz, 48KHz
and 96KHz are supported. The converter can be
locked to external video reference, external AES
reference or internal reference. Input full scale
ranging is adjustable and an internal test tone
generator is also provided.
The module has a built in micro-controller with local
controls, status and alarm indicators and well as
internal flash ram for storing setups. Remote control
and remote status monitoring is possible when used
with the one of the available controller options and
LYNX control software.
The C AD 3320 D / C AD 3321 D is part of the 3000
series of MiniModules, which offer high quality,
modularity and flexibility in a very small form factor
ideal for applications where space is at a premium.
The modules can be used either stand alone using
the optional power supply brick, or as part of a

10 MiniModules can be mounted utilizing the
optional LYNX R FR 3005 / 3010 rack housing. This
includes integrated power supply and optional
remote control interfaces.

Audio Connections
The C AD 3320 D / C AD 3321 D MiniModule is
configured for SubD audio connections for audio
I/O and a BNC connector for video reference. The
SubD connectors should be wired in accordance
with the tables below. Please use high quality
screened cable to prevent the introduction of
noise and interference to the audio signals (twisted
pair suitable for balanced audio signals).

Stand Alone Operation
The C AD 3320 D / C AD 3321 D MiniModule can be
used in a stand alone application. There are two
options for the use of the module in this way.
a) Using the R FR 3005 Rack Frame 1 option. This
allows up to any 10 of the MiniModules to be
secured onto a rack frame assembly for 19 inch
rack mounting. This keeps the modules secured,
organized and out of the way. The R PS 3001
power brick option or the R FR 3010 option is
required to power each module. Please refer to
the reference manuals supplied with these
options for more details.
b) Single Use. The MiniModule can be powered
independently with the R PS 3001 option and
used in any location where this functionality is
required.
Caution. Care needs to be taken
when using the module in this way, as
it is not physically secured. Keep the
module away from the floor to avoid
the risk of someone stepping or
tripping on the unit, and locate the
unit away from excessive sources of
heat and any sources or moisture.
If using more than one MiniModule in any
installation, the R FR 3005/3010 Rack frame
combination is highly recommended.

Reference Manual C AD 3320 D / C AD 3121 D Version1.1
Page 15
Multiple Units
Most applications will require more than one
MiniModule, which can include any of the
available Series 3000 MiniModule product range.
There are two options for mounting multiple units.
a) Using the R FR 3005 Rack Frame option. This
allows up to any 10 of the MiniModules to be
secured onto a rack frame assembly for 19 inch
rack mounting. The R PS 3001 power brick
option or the R FR 3010 option is required to
power each module. Please refer to the
reference manuals supplied with these options
for more details.
b) Using the R FR 3010 Rack frame extension
option. Can be combined with the R FR 3005
Rack frame option. Each module plugs into a
connection bus, which provides common
power for all modules. (No R PS external power
supplies are needed). Remote control and
status monitoring of all modules is possible with
the addition of the R CT 5020 rack controller
and R CT 5030 master controller options. Please
refer to the respective reference manuals for
these options for details of mechanical
installation.
The very small size and density of the MiniModules
combined with the available rack frame options
allows the addition of a complex and custom signal
distribution system without taking any additional
front rack space. The rack frames are designed for
installation in the back of 19-inch racks where there
is normally plenty of available space. Ideal for
mobile truck installations and facility expansions
where space is at a premium.

Electrical Installation.
Stand Alone Operation
The MiniModule requires the R PS 3001 power brick
option for stand-alone operation. Two versions are
available R PS 3001 E for European markets and R
PS 3001 U for the US markets or the R PS 3003-3 desk
power supply.
Please ensure you have the correct power option
for your region. The connection to the module is
made with a small 5-pin connector, which has a
twist bayonet securing system. Please make sure
the connection is solid and locked in place. A strain
relief is included within the module to prevent
excessive strain on the connection.
Signal connections should be made with care,
please ensure connections are correct and
compatible equipment is feeding / receiving the
signals from the module or damage can result.
Caution. Only use the optional LYNX R PS
3001 power modules. Please make sure
the brick is not connected to the main
supply when making the DC power
connection to the module. Ensure the 5-
pin power connector is locked securely in
place.
Caution. Care needs to be taken when
using the module in this way, if it is not
physically secured. Keep the module
away from the floor to avoid the risk of
someone stepping or tripping on the unit,
and locate the unit away from excessive
sources of heat and any sources or
moisture.

Reference Manual C AD 3320 D / C AD 3121 D Version1.1
Page 17
Multiple Units
When installing multiple MiniModule units it is
recommended you use the R FR 3005 Rack Frame 1
and / or R FR 3010 Rack Frame 2 options. Please
refer to the documentation supplied with these
options for details on electrical installation.
Settings and Control
The C AD 3320 D / C AD 3321 D has an integrated
micro-controller, which enables the module to be
configured and controlled locally via the integral
dip-switch and push buttons, or from remote when
using the optional RFR rack frame and control
system. When remote operation is used the local
controls are disabled.
Once set, all settings are automatically saved in
non-volatile internal memory. The module will
always recall the settings used to prior to power off.
The module local configuration is performed from
two 4-position dip-switches which are accessible
through an access space in the bottom of the
module.
Please refer to figure 2 for the location of these
adjustments and use the procedures defined in the
next section to configure the C AD 3320 D / C AD
3321 D module.
