INTRODUCTION
Palladium II
The Palladium II Series of digital video transmitters provide exceptional video quality in high
multipath environments. They are ideal for use inside buildings, in urban areas, and in other ap-
plications where multipath would normally cause video tearing or breakup.
All Palladium II Series transmitters offer three bandwidth modes: DVB-T (6, 7, 8 MHz), Nar-
row (2.5 MHz), and Ultra Narrow (1.25 MHz) channel spacing. DVB-T utilizes 2000 carriers to
transmit video and two channels of voice and data. Palladium II transmitters may be located
on adjacent channels without a guard band. AES 128-bit encryption ensures users of secure
communications.
The Palladium 250 is a small transmitter with a 250 mW RF power output. This unit is ideal for
concealments and shorter range robotic and UAV applications. The package is only 4.2” x 2.6” x
0.65” (approximate
dimensions not including connectors). Power consumption is 12 Watts maximum. All connec-
tions are conveniently located off the ends of the unit.

OPERATION
Using your Palladium II Transmitter
Follow the instructions given in the Quick Start section on pages 4-5. When power is first ap-
plied to the Palladium, the unit reverts to the indicated channel and RF ON state. The Alarm LED
may be ON, which indicates that there is no active video input.
Changing your Transmitter Configuration
The Palladium Transmitter can store up to 8 different configurations, which can be selected
with the Channel Control. Each of these configurations can be programmed into the Transmit-
ter 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 rotate the knob to the next setting.

HEAT SINK
Palladium 250 Heat Sink
The Palladium 250 is supplied with a heat sink attached. DO NOT remove the heat sink unless
you have an alternate mounting surface that will dissipate the heat properly. In ambient
temperatures of 25oC or less, the transmitter chassis should be held at 50oC or less.
WARNING: The Palladium 250 may become too hot to touch without a proper
heatsink attached, such as the one supplied. Damage to internal components
may occur if operated beyond the recommended temperature range. If placed in
an enclosure, proper ventilation and mounting is required. If designing a custom
heatsink, keep the transmitter chassis temperature at 50oC or less. The transmitter
must be mounted to a heatsink on the transmitter’s “blank side” as shown on page 8.

PROGRAMMING
System PC Controller Application Software
Advanced control of the system is available by using the PC control
application software. Typically users may want to customize the default configurations to con-
trol settings such as frequency, scrambling keys, modulation parameters, and video resolution.
The transmitter is controlled by the application DTC_tx_ctrl_v1_3.exe (or higher)
available on the CD delivered with the product.
A PC is required with an available RS232 Serial COM port to control the transmitter.
Installation of the control program is as simple as copying the file 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 these applica-
tions, perhaps with links to the applications from the desktop of the PC.
Getting Started
Use the supplied programming cable
to connect the chosen COM port
of your PC to the transmitter to be
configured.
Launch the application by double
clicking or using the Run...
command.
Connection with a transmitter should
be automatic, but the user can force
selection of the correct COM port
using the drop down, followed by the
Connect button.
Select the channel to be configured
from the unit’s front panel
Channel Switch.
Click Refresh in the application to
display the current configuration.
Update the current settings in the ap-
plication, then click Apply to save to
memory.

PROGRAMMING
Transmitter Control Application
Output Frequency (MHz)
The Output Frequency setting allows selection of TX output frequency in increments of 0.250 MHz within
the allowed tuning range of the unit. If the unit is set to a frequency that is not an integer multiple of 0.25
MHz, the unit will be automatically set to the closest frequency that is an integer multiple of 0.25MHz.
Modulation Bandwidth
Modulation Bandwidth is the actual channel bandwidth that the wireless video link will occupy. The DVB-T
compliant mode requires a bandwidth setting of 6, 7 or 8 MHz. The narrowband mode bandwidth is either
1.25 or 2.5 MHz. Narrower bandwidths increase receiver sensitivity and extend the maximum distance of
the link, however video quality and latency will suffer. Normal default for good quality video is 2.5MHz. The
modulation bandwidth may be set to 1.25 MHz, 2.5 MHz, 6 MHz, 7 MHz, or 8 MHz.
Modulation Output
This control is used to turn ON and OFF the RF output. It must be ON for operation. Turn the transmitter RF
power ON by selecting ON and Apply from the application.
Narrowband FEC
Narrowband FEC sets the forward error correction rate in the narrow bandwidth modes of 1.25 or 2.5 MHz.
Tthe two rates are available are 1/3 and 2/3; the normal default setting for good quality video is 2/3. Chang-
ing the FEC rate to 1/3 will extend the receiver sensitivity by 2 to 3 dB at the expense of degraded video
quality and longer latency.
Narrowband Guard Interval
Narrowband guard interval is used in the narrowband modes of 1.25 and 2.5MHz to adjust for varying
multi-path delay conditions. The default is 1/16 however 1/8 can be selected if necessary to deal with
extreme multi-path delays on long links. Selecting 1/8 guard interval could cause a degradation in video
quality and latency.
Narrowband Modulation
Narrowband modulation is used in the narrowband modes to select between QPSK and 16QAM
modulation. For best range with good video quality, QPSK is used; 16QAM will give better video quality but
will cut down the link range by approximately 50%.
14
PROGRAMMING
DVBT Service Name
DVB-T service name is a place to assign a name for the DVB-T configuration. Press Apply to
save the new name.
DVBT FEC Rate
DVB-T FEC rate selects forward error correction rates in the wideband DVB-T modes. Options
are 1/2, 2/3, and 3/4, with 1/2 giving best range and 3/4 possibly giving better video quality
under certain conditions, recommended default is 1/2.
DVBT Guard Interval
DVB-T guard interval selects guard intervals in the wideband DVB-T modes between 1/32 and
1/4. Use the smallest guard interval that will allow reliable low error rate communications, this
parameter may need to be adjusted when the link is relocated; the recommended default is
1/16.
DVBT Modulation
DVB-T modulation selects the modulation used in the wideband DVB-T mode. Modulations
QPSK, 16QAM, or 64QAM can be selected. QPSK will give best distance and in most cases very
good video quality and low latency.
DVBT Spectrum Inversion
DVB-T spectrum inversion allows flipping the modulated spectrum to compensate for spectrum
inversion that may take place on the receiver side due to high side LO injection.
DVBT 4 KHz Offset
DVB-T 4 KHz offset is not normally used but might improve BER in cases where the TX upcon-
verter I/Q balance is poor.
15
PROGRAMMING
Preset Transmit Mode
Preset transmit mode allows the user a convenient means of automatically setting bandwidth,
FEC, modulation and video frame rate/compression based on link distance requirements.
Options are: None (preset mode not used), Short Range, Medium Range, Long Range, Ultra
Long Range.
Output Power
Output power selects one of two output power attenuator settings; low power or high power,
typically the low power setting is the larger of the two attenuator settings and is used, for
instance, if a power amplifier is added to the transmitter and the output power needs to be
lowered substantially to prevent overloading the input of the power amplifier.
Output Attenuation (dB)
Output attenuation (dB) is the high power attenuator setting.
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,
greater than 0 attenuation = reduced power in 0.25 dB steps.)
Output Attenuation low (dB)
Output attenuation low (dB) is the low power attenuator setting.
16
PROGRAMMING
Video Input
Video input selects the video format going into the MPEG video compressor. Options are: OFF
(no video input typically used when link is used for data only), PAL, NTSC, NTSC no pedestal,
S-Video PAL, S-Video NTSC, S-Video NTSC no pedestal.
MPEG Mode
MPEG mode selects the MPEG compression being used, options are: MPEG2 or MPEG4. MPEG4
mode has to be used when in the 1.25 MHz bandwidth mode since this mode uses a nonstandard
frame rate that is not supported by MPEG2.
MPEG4 Encoding Mode
MPEG4 encoding mode selects the characteristics of the MPEG4 compression. Options are: low
delay interlaced, standard delay interlaced, low delay progressive, standard delay progressive, and SIF.
Interlaced scanning is what is used in conventional over-the-air video. Progressive scan is available on some
cameras and involves scanning an entire frame in one pass rather than two in interlaced scanning. SIF is a
bandwidth-conserving camera scan mode that cuts resolution in half in both the horizontal and vertical.
MPEG4 Frame Rate
MPEG4 frame rate selects the frame rate used in the MPEG4 mode, full frame rate is 30 fps for NTSC and
25 fps for PAL a frame rate of 1/2 or less has to be used in 1.25 MHz bandwidth mode. Options are: Full,
1/2, 1/4, 1/8. or 1/24.
Video Bitrate (status only)
Video bitrate is a status window that will display the video transport data rate, this varies with bandwidth,
modulation, FEC rate and guard interval. The rate will increase with bandwidth and higher levels of
modulation, it will go down as the FEC rate and guard interval are increased. The video bit rate will also
decrease as other service options are activated such as audio and data channels. As a rule video quality and
latency improve as the bit rate is increased.
Horizontal Resolution
Horizontal resolution determines the maximum number of horizontal Pixels that can be sampled by the
video encoder. For optimal performance this setting should be set to the first value that exceeds the
horizontal resolution of the camera in use. Options are: 352, 480, 528, 704 pixels.
17
PROGRAMMING
Video Sharpness
Video sharpness is a filter that may be switched in to smooth out blockiness in the
video.
Audio Encoder
Audio encoder selects quantity of active audio channels (2 maximum), sampling rate
(8, 16 or 32 KHz) which determines upper frequency response, and sampling bits (8 or
12) which determines audio signal to noise. Options are: Off, 8 KHz 8 bit stereo, 16 KHz
8 bit mono, 16 KHz 8 bit stereo, 32 KHz 8 bit mono, 32 KHz 8 bit stereo, 32 KHz 12 bit
mono, 32 KHz 12 bit stereo.
Audio Input Level
Audio input level selects the audio preamp gain level, options are: 0 dB, 12 dB, 24 dB,
36 dB, 48 dB. Use 24 dB for DTC supplied microphones. Note: 3.5 VDC phantom power
is at the microphone input for powering electret condenser microphones.
Unit Name
Unit name allows the user to enter a name (up to 8 characters) for the transmitter that will be
stored in memory.
Sleep Mode
Sleep mode shuts down most functions in the transmitter except the control functions. This
can be used to conserve battery power and yet allow the transmitter to become active again
with a simple command.
Data
Data allows activation of the RS232 half duplex serial data channel and to select parity mode.
Data Baud Rate
Data baud rate selects data channel baud rate, standard rates between 1200 and 115,200 baud
are available.
18
PROGRAMMING
Chaining Input
Chaining input activates the chaining data port. This is not normally used except in
repeaters and high speed data transmission products.
Chain Number
Chain no. (not normally used) assigns a chaining tag number to the stream associated
with the transmitter’s video encoder. This can be user-defined to 0, 1, 2, 3, 4, 5, 6, 7, 8,
or 9. Normally 0.
Chaining Output
Chaining output (not normally used) assigns the output of the video encoder to the chaining
port. Normally OFF.
Current Configuration
Current config indicates the preset that is currently being programmed or viewed, this should
be the same as the preset selected by the channel switch. Enter channel number and click
Apply to change.
Scrambling
Scrambling selects 3 different scrambling options: OFF (no scrambling), AES128, AES256
(optional), or ABS (a proprietary 32 bit scrambling algorithym).
Heartbeat Enable
Heartbeat enable activates a flashing block on the screen video graphic to indicate that a link
is still functioning even if there is no motion on screen.
NOTE: Chaining is digital signal input
and output through the 16-pin Data,
Chaining, and Control Connector.
