TABLE OF CONTENTS manual conventions 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. Quick Start ............................................................................ 4-5 Complete These Steps ................................................................
QUICK START Complete these steps: 1 2 3 Palladium Transmitter, Top View CAMERA MICROPHONE(S) 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.
QUICK START 4 Slide the control panel door open (to the right). 5 When power is applied, the transmitter will power-up to its last state. Ensure that the green RF LED turns ON indicating the unit is transmitting. If needed, push the RF button to begin transmitting. The channel number LED also turns ON, representing the most recent channel setting from the last time the transmitter was used.
INTRODUCTION The Palladium 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 Series transmitters are designed for spectrum-efficient 2.5 MHz channel spacing. Approximately 400 carriers are used to transmit video and two channels of voice and data.
OPERATION Using your Palladium 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 last used channel and RF (ON/OFF) state. One of the green channel LEDs will turn ON indicating the active channel. The Alarm LED may be ON, which indicates that there is no active video input.
HEAT SINKING When to Use a Heat Sink Mounting Screws (4) The Palladium 100 does not require heat sinking in normal service. The Palladium 250 should be attached to a heat sink or heat sinking surface if the unit is to be installed in an enclosure, or in deployments where the ambient temperature could exceed 50oC.
COMPONENTS Channel LEDs These green LEDs, numbered 1 through 8, indicate the channel number currently selected. Each channel represents a set of preconfigured settings. Muiti I/O Connector (6-pin Hirose) This connector provides connections for the DC power input, programming, and 75 Ohm composite video signal. Audio 1 and 2 Connectors (LEMO) These connectors provide the microphone connections to the transmitter. Either one or two microphones can be used with the Palladium Transmitter.
PROGRAMMING System PC Controller Application Software Advanced control of the system is available by using PC control applications. Typically users may want to customize the default configurations to control settings such as frequency, scrambling keys, modulation parameters, and video resolution. The transmitter is controlled by the application DTC_tx_ctrl.exe available on the CD delivered with the product.
PROGRAMMING Transmitter Control Application Output Frequency (MHz) The transmit frequency can be changed by entering the new desired frequency in this field. Values outside the range supported by a particular transmitter type will be rounded to the highest or lowest supported frequency as appropriate. The resolution of the transmit frequency is complex and resolved to the closest achievable within the constants of the supported step sizes of 1MHz, 1.6667 MHz and 2.5 MHz.
PROGRAMMING (As Desired) Output Attenuation This control can be used to make minor adjustments to the output power level, but in normal operation should not be changed from factory settings. NTSC Video Input This control is used to select the composite video input standard. Options are PAL, and NTSC both with and without 7.5 IRE pedestal. 1.1 528 Horizontal resolution The video coding resolution can be selected from 704, 528, 480 and 352 pixels.
PROGRAMMING Audio Input Level This control is used to define the audio gain to be applied to the audio input signal. 0dB is used for line level audio and various options up to 48dB of gain can be applied for microphone inputs. Unit Name Future Use. 24 dB (As Desired) Sleep Mode This control allows the unit to be forced into a Sleep Mode where main functions are disabled, and the power consumption is significantly reduced. NO Data Future use. OFF Data Baud Rate Future use.
PROGRAMMING (Ch. No.) OFF Current Config This field reports the last loaded configuration number. Note that for the Palladium transmitter, changes applied after the configuration has been loaded are saved immediately into the current configuration. Scrambling If the AES scrambling option has been purchased for the system in use, then it is possible to encrypt the link. Scrambling must be enabled at the transmitter by selecting AES in the scrambling field.
PROGRAMMING 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. Write License Code – open a further password protected box for entering license codes for future use.
