NOTE: Describes special issues you should be aware of
while using a particular function.
WARNING: Calls out situations in which
equipment could be damaged or a process could be
incorrectly implemented, but in which operator safety is
not a factor.
TIP: Describes application hints.
RF EXPOSURE STATEMENT
A separation distance of at least 20 cm must be
maintained between the antenna and the body of
the user or nearby persons. When the unit is used
consistent with the previous notice, it conforms to
the requirements of FCC Rules & Regulations, sections
1.1307 & 2.1091, as required by section 90.1217.
CAUTION! Use of antennas with gain above 2.1 dBi may
exceed Maximum Permissible Exposure (MPE) limits.
NOTE: This device is for occupational use only.
Occupational users are those persons who are exposed
as a consequence of their employment, provided these
persons are fully aware of and exercise control over
their exposure.
NOTE: DO not allow the device to directly contact the
skin due to warm operating temperatures.

1. Connect the transmitter antenna to the SMA connector on 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. If using monaural, use Audio 1.
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 (use supplied cable or external source) and
turn ON.
c. Attach a 12 VDC power source to the Multi I/O cable via the Molex connector. The
input voltage range is from 10 to 16 VDC.
WARNING: Do not apply power to the transmitter unless an antenna or non-radiating
load is connected to the Antenna SMA connector.

INTRODUCTION
Palladium Pd2-TX-1000
1 Watt Digital Transmitter
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
applications where multipath would normally cause video tearing or breakup.
All Palladium II Series transmitters offer three bandwidth modes: DVB-T (6, 7, 8 MHz), Narrow
(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 1000 is a small transmitter with a 1 Watt RF power output. This unit is ideal
for concealments and shorter range robotic and UAV applications. The package is only 4.2”
x 2.8” x 2.5” (approximate dimensions not including connectors). Power consumption is 29
Watts maximum. All connections are conveniently located off the ends of the unit. The unit
is water-resistant if mounted with its SMA connector pointing directly upward (with antenna
connected).

OPERATION
Using your Palladium II 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 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 are programmed into the transmitter by
the factory at the time of order.
To cycle through your preconfigured channels rotate the knob to the next setting.
NOTE: FCC 90.203 (e) prohibits anyone other than the manufacturer, qualified service
or maintenance personnel from altering the frequency programming of the transmitter.
Please contact the factory for additional information regarding programming
frequencies.

HEAT SINK
Palladium 1000 Heat Sink
The Palladium 1000 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.
WARNING: The Palladium 1000 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.
