QUICK START VidiVest Palladium FRONT PATCH ANTENNA BUTTON CAMERA REAR PATCH ANTENNA The vest is shipped with all components installed and ready for use. Be careful with the button camera when working on the rear pockets where most of the components are located. Setup the vest on a clean, soft cloth on a tabletop for best results. 1. Inspect the bottom rear pocket section of the vest. Make sure all connectors are secure as shown in the illustration (left). Connectors are keyed and color-coded.
QUICK START When you have selected the channel you need, push the RF button to start transmitting again. The RF LED will turn ON. The transmitter RF should always be set to ON. The vest is deactivated by disconnecting power. 5. 6. 7. 8. 9. NOTE: The RF switch should remain ON during normal use. The RF automatically shuts off during programming to prevent accidental transmissions on unintended frequencies. DO NOT HOLD THE RF BUTTON DOWN FOR MORE THAN ONE SECOND, or the unit will go into sleep mode.
OVERVIEW The Palladium VidiVest Vest is a covert, body worn, 100 mW COFDM microwave video transmission garment system. Palladium digital technology and our advanced antenna system combine to provide high signal quality and very effective mobility. The vest conceals all components and provides sheilding from transmitter heat. Power is supplied by a concealed 9 AA battery pack. The lightweight vest is designed to fit many body sizes and is ventilated for comfort.
COMPONENTS Component Placement Optional Microphone System Components Patch Antenna Splitter Patch Antenna • Vest – White with vents. Machine wash on gentle cycle with detergent. Hang dry. • Transmitter – 100 mW, with eight programmable channels • Button Camera – Color, 5VDC Front • Antenna – Two-Patch system with Splitter Back • Two Audio Inputs • Battery Pack for 9AA batteries • Batteries – (Lithium are supplied.
COMPONENTS 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. If the video source (Camera) is not connected, the ALARM LED will be ON.
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. A PC is required with an open RS232 Serial COM port to configure a transmitter.
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 resolved to the closest achievable within the supported step sizes of 1MHz, 1.6667 MHz and 2.5 MHz.
PROGRAMMING 0 Advanced options are shown in blue. These options are for trained and experienced technicians only. NTSC 1.1 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. Video Bitrate (status only) The video bit rate is automatically maximized in each configuration when Chaining Input is turned off.
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. 3.5 VDC is applied at the microphone connector for “phantom power” used to power electret condenser microphones. Input impedance is 5K Ohms. The transmitter works best with a high-impedance audio source. Unit Name Enter up to 16 characters to identify unit as desired.
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 Scrambling is enabled at the transmitter by selecting AES in the scrambling field. At this point the user will need to ensure that the correct key is in use and this is done by using Options > Write AES key.
