Thermal Issues

Higher power Palladium
1 and 2 Watt Transmitters
feature mounting tabs for
convenient installation and
heat dissipation. Proper
heat sink mounting is
required. Operating without
proper heat sinking would
cause overheating and
damage to electronic
components.

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 to the Multi I/O cable via the Molex

connector. The power source must be capable of supplying a minimum
of 30 Watts for the PdTx-1000 and 36 Watts for the PdTx-2000.

NOTE: Eight Channel LEDs are located under the sliding control
panel door. If all 8 green LEDs are flashing, this indicates that your
power source is low.

QUICK START

4 Slide the control panel door to the right.
5 When power is applied, the green RF LED turns ON. The channel

number LED also turns ON, representing the most recent channel
setting from the last time the transmitter was used. Push the RF button
to transmit.

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 for one second 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.

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-1000

1 Watt Digital Transmitter

Palladium Transmitters

The Palladium Pd-TX-1000 and Pd-TX-2000 digital video transmitters are
high power COFDM transmitters designed for longer range transmission.
The Pd-TX-1000 provides 1 Watt of RF output power and the Pd-TX-2000
has 2 Watts of RF output power.

Both models use internal high-linearity power amplifiers to boost the
output power. Users must consider heat generation under anticipated
operating environments and ensure sufficient heatsinking and/or cooling.
A number of heat sinks are available for use with these units.

These Palladium Transmitters are designed for stand-alone operation,
off the body in surveillance applications, unattended long range
transmitters with sufficient battery or AC power sources, and in larger
robotic and UAV platforms.

All Palladium Series transmitters are designed for 2.5 MHz channel
spacing and use approximately 400 carriers to transmit video and two
channels of voice or data. Transmitters may be located on adjacent
channels without a guard interval. The transmitter housings are built out
of rugged milled aluminum, with heat sink mounting tabs incorporated
into the chassis.
