Rio Rancho, NM 3
Introduction
DSW (Digital Secure Wireless) is designed for no-com-
promise applications where performance and security
are the highest priority.
A completely new digital architecture was developed
for the DSW wireless system. Extended operating
range rivals the best analog and Digital Hybrid Wire-
less®systems, with remarkable audio quality and only
2.5 ms of latency. The system operates on standard
UHF FCC Part 74 frequencies (TV channel band).
256-bit encryption is applied to the transmitted signal
stream for security against eavesdropping. The algo-
rithm conforms to the AES 256-CTR standard.
DR Modular Receiver
The DR receiver is a 1RU modular, six-channel design
with a host mainframe that contains the DSP, micro-
processor, antenna multicoupler and control interface.
Receiver modules are installed on either side of the
mainframe. No tools are required to remove and install
the receiver modules. Each module will tune across a
25.6 MHz range.
Antenna ports on the rear panel accept input from
remote antennas, with a “loop-thru” output to another
mainframe. A high quality internal multicoupler distrib-
utes the RF signal to the receiver modules.
For rack mount installations, a kit is available to mount
antenna inputs (BNC connectors) on the receiver front
panel using a coaxial cable routed through the receiver
chassis to the rear panel connections.
DB Belt Pack Transmitter
The DB belt pack transmitter is encased in a solid
machined aluminum housing with a membrane switch
panel and backlit LCD interface. The servo bias input
circuitry will work with a wide variety of microphones
and line level sources, Input gain is adjustable over
a wide range in 1 dB steps to optimize the signal to
noise ratio and dynamics of the audio.
The transmitter tunes across the entire frequency
range of the DSW system, from 470 MHz to 691 MHz.

a balanced analog output.
Pin 1 Ground/Shield
Pin 2 Data (+)
Pin 3 Data (–)
Pins 2 and 3 carry the digital audio. Although polarity
is not an issue, it is good practice to maintain a “pin
to pin” connection - pin 1 to pin 1, pin 2 to pin 2, pin 3
to pin 3 in cables that terminate in XLR connectors at
both ends. It is best to use 110 ohm cable designed to
carry digital signals. Conventional microphone cables
may cause problems, especially with distances over 30
or 40 feet.
For pinout details of wiring to a DB-25 connector, refer
to the documentation for the device you are using.
Channel assignments per connector are marked on
the rear panel of the receiver.
Connections for Computer Interface
Connection to a computer for set up is easiest with a
single or multiple USB connection.
USB Hub
NOTE: Audio is not passed through the USB port. It
is used only for control and monitoring settings.
Receivers can also be connected via RS-232 ports on
PCMCIA cards and remote control systems.

Gain - This setting determines the signal to
noise ratio and dynamic range that the system
will deliver. Review the setup procedure care-
fully for optimal performance.
Freq. - Frequency can be set manually.
ProgSw - The programmable switch on the
top panel of the transmitter can be configured
for different functions with this setup menu.
Rolloff - The low frequency audio rolloff is
adjustable to optimize performance for envi-
ronmental conditions or personal preference.
Phase - The polarity of the audio signal can
be reversed to match other microphones in
the system. Differences in polarity are due to
microphone designs and connector wiring.
BatType - This setting makes the battery sta-
tus display more accurate, since alkaline and
lithium batteries behave differently as they are
discharged.
BatTime - A built-in timer can be used with
any battery type, but it is especially valuable
with rechargeable batteries such as NiMH
types. The voltage remains fairly constant
across the discharge time of a rechargeable
battery, then drops quickly near the end of
the operating time. The most accurate way to
determine runtime status is by testing the time
provided by a particular battery brand and
type, then using a timer to determine remain-
ing runtime.
Locked? - The keypad can be locked out to
prevent inadvertent changes to be made.
Backlit - The brightness and appearance of
the LCD can be adjusted for better viewing in
different lighting conditions.
About - Displays the firmware revision.
Default - The factory default settings can be
restored with this single setup screen.
WipeKey - The encryption key can be erased
with this setup screen.

Copying Transmitter Settings To and From
the Receiver
Connect the key cable from the jack labeled KEY on
the front of the receiver to the micro USB port on the
side of the transmitter.
If transmitter settings are defined in the receiver, they
can be transferred to a connected transmitter, or cop-
ied from a transmitter to a receiver channel using the
key cable.
Transmitter Settings Screen
Press MENU/SEL and navigate to the TX MENU, then
to the SEND SETTINGS (microphone) icon. Press the
encoder to enter the transmitter settings screen.
Select the desired channel with the CHOOSE TX op-
tion at the bottom of the screen.
Send Settings to Transmitter
After the channel is selected, highlight the SEND
SET option at the bottom of the screen. Connect the
transmitter with the USB cable and press the encoder
to start the transfer.
The transmitter LCD will display RECEIVED when the
settings have successfully transferred.
If the transfer cannot be completed, an error message
will appear.
Get Settings from Transmitter
The settings in the transmitter can be transferred to the
receiver for storage or editing with the GET SET option
in the setup screen.
The transmitter must be turned fully on and tuned to
the selected channel on the receiver.
Select the desired channel and then the GET SET
option. Turn the transmitter fully on with the RF output
enabled and press the encoder to start the transfer.
An error message will appear if no RF signal is being
received.
NOTE: Settings will be displayed on the Transmitter
Settings screen, but changes are not made here.
Settings are adjusted in the TX MENU as described
on previous pages, on the transmitter itself, or with
the Wireless Designer software.

System Setup
These instructions apply to setup using the front panel
LCD. If you will be using Wireless Designer for setup,
instructions are in the help files supplied with the soft-
ware.
Install Receiver Modules
Turn power off on the DR mainframe. Install the mod-
ules as needed. Any module can be installed in any
position in the mainframe assembly. When the power
is turned on, the modules will be detected during the
bootup sequence and an icon for each one will appear
on the LCD.
Generate Encryption Key
On the receiver LCD, navigate to the KEY MANAGE-
MENT item in the Top Menu and press the encoder to
enter the setup screen.
In this setup screen, the type of encryption key policy
can be set, a new key generated or the existing key
can be deleted.
The encryption key policy can be configured as:
• PERSISTENT
• ONE-TIME KEY
A PERSISTENT key will remain in receiver and trans-
mitter memory until it is replaced with a new key or
manually deleted using WIPE KEY in the menus.
A ONE-TIME ONLY key is used for maximum secu-
rity. The key exists only as long as the power on both
receiver and transmitter remains on during a single
session. If a transmitter is powered off, but the receiver
has remained turned on, the key must be sent to the
transmitter again. If the power is turned off on the
receiver, the entire session concludes and a new key
must be generated and sent to all transmitters.
In either key policy, there are 256 “instances” available
each time a new key is generated. “Instance” refers to
a transfer of the key from receiver to transmitter. Each
instance contains a unique key. The number of instanc-
es is reduced each time a key is transferred. When
the number of instances reaches 10, a warning will be
displayed on the LCD.
Select the NEW KEY option and press the encoder to
enter the setup screen.
NOTE: It is generally more convenient to use a
PERSISTENT key during setup, since power may
be need to be cycled on and off on the transmitters
or receiver until the system is completely set up.
The stored key can be deleted manually with the WIPE
KEY option.
Initial Transmitter Setup
Attach the antenna and install the batteries into the
transmitters that will be used. Turn the power on and
observe the BATT LED on the transmitter. Verify that
the batteries are fresh or fully charged (the LED will
glow green with good batteries).
Transfer Encryption Key to Transmitters
On the receiver LCD, navigate to the KEY TRANSFER
item in the Top Menu and press the encoder to enter
the setup screen.
YES indicates the transmitter is connected
Connect the transmitter with the key cable and press
the encoder to start the transfer. The LED on the top
right corner of the keypad will glow blue when the key
has been transferred successfully.
NOTE: The key can be transferred with the
transmitter either fully powered up or in the standby
mode with the RF output turned off.
