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 50

o

C or less. The transmitter must be 

mounted to a heatsink on the transmitter’s “blank side” as shown on page 8.
