3NOTE: 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 STATEMENTA 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.manual conventionsQuick Start ....................................................................................................................4-5Accessories ........................................................................................................................ 5Introduction ........................................................................................................................ 6Operation ........................................................................................................................ 7Using your Palladium II Transmitter .............................................................................. 7Changing your Transmitter Configuration ................................................................. 7Heat Sink ....................................................................................................................8-9Components .............................................................................................................. 10-11Programming ......................................................................................................................11Specifications .............................................................................................................. 12-13Notes ......................................................................................................................14Contact Us ......................................................................................................................15 TABLE OF CONTENTS
4AntennaAudioCameraPower SupplyPower OptionPALLADIUM II1. 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.Complete these steps:Typical Wiring ConfigurationQUICK START A2 L A1 R/MPalladium Transmitter, Top View 23Thermal IssuesProper heat sink mounting is recommended for optimal performance.

6INTRODUCTIONPalladium Pd2-TX-1000 1 Watt Digital TransmitterPalladium IIThe 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).
7OPERATIONUsing your Palladium II TransmitterFollow 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 ConfigurationThe 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.

9HEAT SINKPalladium 1000 Heat SinkThe 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.
