OVERVIEW
The Palladium VidiVest Vest is a covert, body worn, 100 mW COFDM
microwave video transmission garment system. Palladium digital
technology and our advanced antenna system combine to provide high
signal quality and very effective mobility. The vest conceals all
components and provides sheilding from transmitter heat. Power is
supplied by a concealed 9 AA battery pack.
The lightweight vest is designed to fit many body sizes and is ventilated for
comfort. It is designed to hold all system components as an undergarment
for use with a casual shirt. The design holds all components close to the
body, allowing a loosely fitting shirt to be buttoned over it without
protrusions or wires showing. A hard-wired ON/OFF switch is available as
an option. An optional wireless keyfob ON/OFF switch is also available.
The high-resolution color CCD camera is disguised as a shirt button.
The Palladium transmitter offers integral AES encryption. Two audio
inputs are provided.
Deployment is quick and easy. All connectors are color-coded and locking.
A special two-patch antenna harness, built into the vest, provides an omni-
directional transmission pattern. The entire vest system is powered from a
single battery pack, which holds 9 AA size Lithium batteries. A set of
NON-rechargeable Lithium cells have been provided in the kit. Battery life
with one set of fresh Lithium cells is more than 3 hours.
Note: Only Lithium Ion AA batteries are recommended.

COMPONENTS
Typical Palladium Operating Temperatures
A wide range of variables can affect the temperature of electronic devices
including ambient temperature, air flow, heat sink and mounting
considerations. In a typical test performed at room temperature, the
Palladium 100 has been observed to have a baseplate operating
temperature of 37oC (99oF). In other words, it can get warm. The VidiVest
Palladium has a special heat shield between the transmitter chassis and
the user to provide comfort in entended missions or in warm
environments. Be sure this is properly installed before each mission.
Using your Palladium Transmitter
Follow the instructions given in the Quick Start section on pages 4-5.
When power is first applied to the Palladium, the unit reverts to the last
used channel and RF (ON/OFF) state. One of the green channel LEDs will
turn ON indicating the active channel. If the video source (Camera) is not
connected, the ALARM LED will be ON.
NOTE: Since the Palladium transmitter always returns to the last
configuration on power-up, the unit should always be deployed with
the RF switch ON. Therefore, once deployed, control of the unit must
be restricted to applying and removing power. See the Quick Start
(pages 4-5).
Changing your Transmitter Configuration
The Palladium Transmitter can store up to 8 different configurations,
which can be selected on the front panel. Each of these configurations can
be programmed into the Transmitter with the supplied DTC Programming
Software and a Windows PC. Refer to the Programming section on page 10
for more information.
To cycle through your preconfigured channels press the CONFIG button
once to advance to the next setting. By default, the Palladium will turn
OFF the transmitted signal while you are changing channels. This is to
prevent accidental interference. Push the RF button after channel selection
to resume RF transmission of your video image.

PROGRAMMING
System PC Controller Application Software
Advanced control of the system is available by using PC control
applications. Typically users may want to customize the default
configurations to control settings such as frequency, scrambling keys,
modulation parameters, and video resolution.
The transmitter is controlled by the application DTC_tx_ctrl.exe
available on the CD delivered with the product.
A PC is required with an open RS232 Serial COM port to configure a
transmitter.
Installation of the control program is as simple as copying it from the CD
to a suitable location on the PC. No install shield routine is launched.
Note that the application generates its own log and initialization
files, so it is best to create a dedicated directory for the
application, perhaps with a shortcut to the application
from the desktop of the PC.

Transmitter Control Application
Output Frequency (MHz)
The transmit frequency can be changed by entering the new desired
frequency in this field. Values outside the range supported by a particular
transmitter type will be rounded to the highest or lowest supported
frequency as appropriate. The resolution of the transmit frequency is
resolved to the closest achievable within the supported step sizes of 1MHz,
1.6667 MHz and 2.5 MHz.
Modulation Output (same as RF button functionality)
This control is used to turn on and off the RF output. After a configuration
change, the output always reverts to OFF. It must be ON for operation.
Modulation FEC
The default FEC is 2/3, however improved range operation can be achieved
by selecting FEC 1/3. FEC 1/3 will improve signal range by 3dB. However
FEC 1/3 reduces link capacity to 1.2Mb/s.
Modulation Guard Interval
The Guard Interval is fixed at 1/16 in current firmware releases.
Modulation Bandwidth
For the Palladium transmitter products, the modulation bandwidth is fixed
at 2.5MHz in current firmware release.
COFDM Mode
The COFDM mode can be changed between QPSK and 16QAM. QPSK is
the default mode and will give the strongest most rugged RF link
performance. Selecting 16QAM reduces the link performance by 5dB but
improves the link data throughput. Default values are shown in red.

Output Attenuation
This control can be used to make minor adjustments to the output power
level, but in normal operation should not be changed from factory settings.
(0 attenuation = full output power.)
Video Input
This control is used to select the composite video input standard. Options
are PAL, and NTSC both with and without 7.5 IRE pedestal.
Video Bitrate (status only)
The video bit rate is automatically maximized in each configuration when
Chaining Input is turned off. This control can be used to set the video
bitrate within the constraints of capacity available in the channel, but only
when Chaining Input is set to ON. Chaining CANNOT be enabled on
normal transmitters, and as such video bit rate control is automatic.
Horizontal resolution
The video coding resolution can be selected from 704, 528, 480 and 352
pixels. For optimum performance, choose a resolution one step better than
your camera’s resolution.
Audio Encoder
The Audio can be turned ON and OFF with this control. Audio is OFF by
default, but there are several audio modes that vary from very high quality
to speech grade that can be selected with this control. One or two channel
audio is supported. For optimum link performance, select the lowest audio
quality necessary to support the mission.

Audio Input Level
This control is used to define the audio gain to be applied to the audio
input signal. 0dB is used for line level audio and various options up to
48dB of gain can be applied for microphone inputs. 3.5 VDC is applied at
the microphone connector for “phantom power” used to power electret
condenser microphones. Input impedance is 5K Ohms. The transmitter
works best with a high-impedance audio source.
Unit Name
Enter up to 16 characters to identify unit as desired.
Sleep Mode
This control allows the unit to be forced into a Sleep Mode where main
functions are disabled, and the power consumption is significantly re-
duced.

Current Config
This field reports the last loaded configuration number. Note that for the
Palladium transmitter, changes applied after the configuration has been
loaded are saved immediately into the current configuration.
Scrambling
Scrambling is enabled at the transmitter by selecting AES in the
scrambling field. At this point the user will need to ensure that the correct
key is in use and this is done by using Options > Write AES key. The
key is 128 bits and is entered as 32 ASCII hexadecimal characters (0-9 and
A-F). (256 bit is optional.) See page 15.
Video Locked (Status Only)
This status information indicates whether the transmitter is successfully
locked to the incoming composite video signal. Unlocked status may
indicate cabling faults, or poor quality incoming video feeds to the unit.
