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. WARNING: Do not apply power to the transmitter unless an antenna or non-radiating load is connected to the Antenna AUDIO SMA connector. INPUT(S) Connections SPLITTER • Camera to Transmitter: 3-Pin to 3-Pin • Audio (if used): Two Lemo connectors (Push/Pull locking) • Power (Battery pack to TX): 2-Pin to 2-Pin • Antenna: SMA Male to TX SMA Connector 2. Remove the battery holder by carefully releasing the locking connector. Each section of the battery holder has a cover, which must be removed with a Phillips screwdriver to allow the batteries to be inserted or changed. 3. Install 9 NEW Lithium AA size batteries, observing proper polarity and 9 AA BATTERY replace the screws for each section. PACK 4. The transmitter has been factory programmed to eight preset channels. Make sure the channel frequency selected matches the receiver’s frequency. Slide the control panel door open (to the right). If you need to change the operating channel, press the CONFIG button to cycle through the 8 available channels indicated by the channel number VidiVest Palladium Wiring Diagram 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. DTC COMMUNICATIONS, INC. 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. In sleep mode, the unit is non-functional. If necessary, recover from sleep mode by pressing and holding the RF button for more than two seconds. When power is applied, the transmitter will power-up to its last RF ON/OFF 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. Put the vest on (refer to photos page 6). Tighten the Velcro side straps so that the system components are held closely to the body. The rear flap of the vest should be hanging loose. Orient the camera on the Velcro for a proper (right side up) picture. Put the shirt on over the vest. Button the camera through the appropriate buttonhole in the shirt. (See photos right.) Test the system. Verify the camera is properly positioned by looking at the receiver’s monitor. Walk quickly for a few steps, returning to the monitor. Make sure the camera’s field of view has not changed. Reposition if necessary. Double-check the camera picture and angle before the mission. Your Transmitter is now operational. Confirm its signal with your Palladium Receiver. NOTE: The red ALARM LED typically indicates no video input. It could also indicate a hardware failure or low battery power. Casual Shirt Button Camera The camera position can be adjusted to desired button hole. DTC COMMUNICATIONS, INC. 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. It is designed to hold all system components as an undergarment for use with a casual shirt. The design holds all components close to the body, allowing a loosely fitting shirt to be buttoned over it without protrusions or wires showing. A hard-wired ON/OFF switch is available as an option. An optional wireless keyfob ON/OFF switch is also available. The high-resolution color CCD camera is disguised as a shirt button. The Palladium transmitter offers integral AES encryption. Two audio inputs are provided. The VidiVest Fits Snugly On The Body Using Velcro Fasteners. One size fits all. DTC COMMUNICATIONS, INC. Deployment is quick and easy. All connectors are color-coded and locking. A special two-patch antenna harness, built into the vest, provides an omnidirectional transmission pattern. The entire vest system is powered from a single battery pack, which holds 9 AA size Lithium batteries. A set of NON-rechargeable Lithium cells have been provided in the kit. Battery life with one set of fresh Lithium cells is more than 3 hours. Note: Only Lithium Ion AA batteries are recommended.

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. NOTE: Since the Palladium transmitter always returns to the last configuration on power-up, the unit should always be deployed with the RF switch ON. Therefore, once deployed, control of the unit must be restricted to applying and removing power. See the Quick Start (pages 4-5). Changing your Transmitter Configuration The Palladium Transmitter can store up to 8 different configurations, which can be selected on the front panel. Each of these configurations can be programmed into the Transmitter with the supplied DTC Programming Software and a Windows PC. Refer to the Programming section on page 10 for more information. To cycle through your preconfigured channels press the CONFIG button once to advance to the next setting. By default, the Palladium will turn OFF the transmitted signal while you are changing channels. This is to prevent accidental interference. Push the RF button after channel selection to resume RF transmission of your video image. Typical Palladium Operating Temperatures DTC COMMUNICATIONS, INC. A wide range of variables can affect the temperature of electronic devices including ambient temperature, air flow, heat sink and mounting considerations. In a typical test performed at room temperature, the Palladium 100 has been observed to have a baseplate operating temperature of 37oC (99oF). In other words, it can get warm. The VidiVest Palladium has a special heat shield between the transmitter chassis and the user to provide comfort in entended missions or in warm environments. Be sure this is properly installed before each mission. 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. ALARM LED This red LED typically indicates a valid video signal is not present. It can also indicate a hardware failure or low battery power. RF LED This green LED indicates that the RF output is ON. 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. RF Button This membrane switch toggles ON/OFF the RF output. Normally this should be left ON. CONFIG Button This membrane switch cycles through the eight channels. DTC COMMUNICATIONS, INC. 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. Getting Started • Use the supplied programming cable to connect the chosen COM port of the PC to transmitter to be configured. Connect DC power. • Launch the application by double clicking or using the Start > Run... command. • Connection with a transmitter should be automatic, but the user can force selection of the correct COM port using the drop down port menu, followed by the Connect button. 10 DTC COMMUNICATIONS, INC. Installation of the control program is as simple as copying it from the CD to a suitable location on the PC. No install shield routine is launched. Note that the application generates its own log and initialization FRONT PATCH ANTENNA files, so it is best to create a dedicated directory for the application, perhaps with a shortcut to the application REAR PATCH ANTENNA from the desktop of the PC. PROGRAMMING CABLE To PC Serial RS-232 PORT AUDIO INPUT(S) SPLITTER 9 AA BATTERY PACK 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. Modulation Output (same as RF button functionality) This control is used to turn on and off the RF output. After a configuration change, the output always reverts to OFF. It must be ON for operation. Modulation FEC The default FEC is 2/3, however improved range operation can be achieved by selecting FEC 1/3. FEC 1/3 will improve signal range by 3dB. However FEC 1/3 reduces link capacity to 1.2Mb/s. Modulation Guard Interval The Guard Interval is fixed at 1/16 in current firmware releases. Modulation Bandwidth For the Palladium transmitter products, the modulation bandwidth is fixed at 2.5MHz in current firmware release. COFDM Mode The COFDM mode can be changed between QPSK and 16QAM. QPSK is the default mode and will give the strongest most rugged RF link performance. Selecting 16QAM reduces the link performance by 5dB but improves the link data throughput. (your frequency) OFF Advanced options are shown in blue. These options are for trained and experienced technicians only. 2/3 1/16 2.5 MHz QPSK Default values are shown in red. DTC COMMUNICATIONS, INC. 11 PROGRAMMING 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. This control can be used to set the video bitrate within the constraints of capacity available in the channel, but only when Chaining Input is set to ON. Chaining CANNOT be enabled on normal transmitters, and as such video bit rate control is automatic. 528 Horizontal resolution The video coding resolution can be selected from 704, 528, 480 and 352 pixels. For optimum performance, choose a resolution one step better than your camera’s resolution. OFF Audio Encoder The Audio can be turned ON and OFF with this control. Audio is OFF by default, but there are several audio modes that vary from very high quality to speech grade that can be selected with this control. One or two channel audio is supported. For optimum link performance, select the lowest audio quality necessary to support the mission. Default values are shown in red. 12 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. (0 attenuation = full output power.) DTC COMMUNICATIONS, INC. 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. 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. 24 dB (As Desired) Advanced options are shown in blue. These options are for trained and experienced technicians only. NO Data Future use. Do not change. OFF Data Baud Rate Future use. Do not change. 1200 Chaining Input Future use. Do not change. OFF Chain Number Future use. Do not change. Default values are shown in red. DTC COMMUNICATIONS, INC. 13 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. The key is 128 bits and is entered as 32 ASCII hexadecimal characters (0-9 and A-F). (256 bit is optional.) See page 15. Video Locked (Status Only) This status information indicates whether the transmitter is successfully locked to the incoming composite video signal. Unlocked status may indicate cabling faults, or poor quality incoming video feeds to the unit. Software Version (Status Only) This status information describes the version of the software running the transmitter product. FPGA Version (Status Only) Engineering use only. Serial Number (Status Only) This status information is the electronic serial number of the transmitter PCB. This number can be used for upgrades or support. Chaining (Status Only) Future use. Default values are shown in red. 14 DTC COMMUNICATIONS, INC.
