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 Quick Start ............................................................................ 4-5 Accessories ................................................................
QUICK START Complete these steps: A2 L A1 R/M 1 Connect the transmitter antenna to the SMA connector on the bottom 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. 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.
QUICK START 4 CHANNEL TELEMETRY 4 Set to the required configuration as indicated by the channel numbers. Refer to the Programming section on page 10 for more information on channel settings. Your Transmitter is now operational. Confirm its signal with your Palladium Receiver. Accessories • 10 cell AA Battery Pack • 12 VDC 2.5A Power Supply & AC Line Cord • Microphone, Body-Worn, (2) • Power & Video Cable • Camera Power Cable (2.
INTRODUCTION CHANNEL TELEMETRY 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.
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.
COMPONENTS Top Controls/Connectors Multi-I/O Connector The Multi-I/O Connector is covered on page 9. Data Chaining & Control Connector This connector is normally covered. Audio 2 (left) and Audio 1 (right/mono) LEMO Conn. These connectors provide the audio input connections to the transmitter. Either one or two audio inputs can be used with the Palladium II Transmitter. ALARM LED This red LED indicates a valid video signal is not present. 8 DTC COMMUNICATIONS, INC.
COMPONENTS Transmitter Antenna Connector (SMA) This connector attaches to the transmitter antenna and carries the RF output signal. Always ensure the transmitter antenna is attached before operating the Palladium Transmitter. Palladium II VIDEO TX Video In 75 Ohm 6 Muiti I/O Connector (6-pin Hirose) This connector provides connections for the DC Power Input, DC Camera Power, Programming, and 75 Ohm Composite Video Signal.
PROGRAMMING Getting Started System PC Controller Application Software •Use the supplied programming cable to connect the chosen COM port of your PC to the transmitter to be configured. Advanced control of the system is available by using the PC control application software. Typically users may want to customize the default configurations to control settings such as frequency, scrambling keys, modulation parameters, and video resolution. •Launch the application by double clicking or using the Run...
Transmitter Control Application Output Frequency (MHz) PROGRAMMING The Output Frequency setting allows selection of TX output frequency in increments of 0.250 MHz within the allowed tuning range of the unit. If the unit is set to a frequency that is not an integer multiple of 0.25 MHz, the unit will be automatically set to the closest frequency that is an integer multiple of 0.25MHz. Modulation Bandwidth Modulation Bandwidth is the actual channel bandwidth that the wireless video link will occupy.
PROGRAMMING DVBT Service Name DVB-T service name is a place to assign a name for the DVB-T configuration. Press Apply to save the new name. DVBT FEC Rate DVB-T FEC rate selects forward error correction rates in the wideband DVB-T modes. Options are 1/2, 2/3, and 3/4, with 1/2 giving best range and 3/4 possibly giving better video quality under certain conditions, recommended default is 1/2. DVBT Guard Interval DVB-T guard interval selects guard intervals in the wideband DVB-T modes between 1/32 and 1/4.
PROGRAMMING Preset Transmit Mode Preset transmit mode allows the user a convenient means of automatically setting bandwidth, FEC, modulation and video frame rate/compression based on link distance requirements. Options are: None (preset mode not used), Short Range, Medium Range, Long Range, Ultra Long Range.
PROGRAMMING Video Input Video input selects the video format going into the MPEG video compressor. Options are: OFF (no video input typically used when link is used for data only), PAL, NTSC, NTSC no pedestal, S-Video PAL, S-Video NTSC, S-Video NTSC no pedestal. MPEG Mode MPEG mode selects the MPEG compression being used, options are: MPEG2 or MPEG4. MPEG4 mode has to be used when in the 1.25 MHz bandwidth mode since this mode uses a nonstandard frame rate that is not supported by MPEG2.
PROGRAMMING Video Sharpness Video sharpness is a filter that may be switched in to smooth out blockiness in the video. Audio Encoder Audio encoder selects quantity of active audio channels (2 maximum), sampling rate (8, 16 or 32 KHz) which determines upper frequency response, and sampling bits (8 or 12) which determines audio signal to noise. Options are: Off, 8 KHz 8 bit stereo, 16 KHz 8 bit mono, 16 KHz 8 bit stereo, 32 KHz 8 bit mono, 32 KHz 8 bit stereo, 32 KHz 12 bit mono, 32 KHz 12 bit stereo.
PROGRAMMING Chaining Input Chaining input activates the chaining data port. This is not normally used except in repeaters and high speed data transmission products. Chain Number Chain no. (not normally used) assigns a chaining tag number to the stream associated with the transmitter’s video encoder. This can be user-defined to 0, 1, 2, 3, 4, 5, 6, 7, 8, or 9. Normally 0. NOTE: Chaining is digital signal input and output through the 16-pin Data, Chaining, and Control Connector.
PROGRAMMING File Change Logfile – opens a standard Windows file save dialog box which allows the user to change the path and name of the log file generated by the application. Exit – exits the control application. Options Timeouts – password protected access to change timeouts used during the serial communications between the unit and the controller. Engineering – password protected access to further diagnostic and calibration features.
