ANTENNA
Complete these steps:
1 Connect the transmitter antenna to the SMA connector on the top of the
Palladium unit.
2 If you plan to use audio, connect one or two microphones to the Audio 1
and/or Audio 2 LEMO connectors.
3 Connect power and video input via the Multi I/O cable to the 6-pin
Hirose connector:
a Attach your camera video input (75 ohm composite video source in
PAL or NTSC) to the Multi I/O cable BNC connector.
b Apply the necessary power to your camera and turn ON.
c Attach a 12 VDC power source (such as the supplied battery pack or
the AC power adapter) to the Multi I/O cable via the Molex connector.
The input voltage range is from 10 to 18 VDC.
NOTE: Eight Channel LEDs are located under the sliding control
panel door. If all 8 green LEDs are flashing, this indicates that your
battery source is low.

Thermal Issues
Higher power Palladium Pd-TX-250 Transmitters feature
mounting tabs for convenient mounting and heat
dissipation. If your Palladium Transmitter has these tabs,
proper heat sink mounting is recommended for optimal
performance. An optional heat sink can be purchased
from DTC. See page 8 for heat sinking instructions.
QUICK START
4 Slide the control panel door open (to the right).
5 When power is applied, the transmitter will power-up to its last state.
Ensure that the green RF LED turns ON indicating the unit is
transmitting. If needed, push the RF button to begin transmitting.
The channel number LED also turns ON, representing the most recent
channel setting from the last time the transmitter was used.
6 If you need to change the operating channel, press the CONFIG button
to cycle through the 8 available channels indicated by the channel
number LEDs. Refer to the Programming section on page 10 for more
information on channel settings. When you change the channel
configuration, the RF transmission is automatically switched OFF to
prevent accidental interference. When you have selected the channel
you need, push the RF button to start transmitting again. The RF LED
will turn ON.
NOTE: A red ALARM LED indicates that no video is connected.
Your Transmitter is now operational. Confirm its signal with your
Palladium Receiver.
WARNING: Do not apply power to the transmitter unless an antenna
or non-radiating load is connected to the Antenna SMA connector.
NOTE: The RF switch should remain ON during normal use. The RF
automatically shuts off during programming to prevent accidental
transmissions on unintended frequencies.

INTRODUCTION
Palladium Pd-TX-100
100-Milliwatt Digital Transmitter
The Palladium 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 applications where multipath
would normally cause video tearing or breakup.
All Palladium Series transmitters are designed for spectrum-efficient 2.5
MHz channel spacing. Approximately 400 carriers are used to transmit
video and two channels of voice and data. Palladium transmitters may be
located on adjacent channels without a guard band. AES 128-bit
encryption ensures users of secure communications.
The Palladium 100 is a small transmitter with a 100 mW RF power output.
This unit is ideal for concealments and shorter range robotic and UAV
applications. The package is only 7.5” x 2.5” x 0.75”. Power consumption is
6 Watts. All connections are conveniently located off the ends of the unit.
Many users will want to power this device with disposable batteries.
The Palladium 250 incorporates an internal power amplifier bringing total
power output to 250 mW. Height and width are identical to the Palladium
100, with the depth of the unit increasing an additional 0.5”. The
Palladium 250 is ideal for many surveillance applications and short to
mid-range robotic and UAV applications.
Both versions are built out of rugged milled aluminum housings. The
Palladium 250 features mounting tabs for convenient heatsinking (page 8).
