The vest is deactivated bydisconnecting power.NOTE: The RF switch should remain ON during normal use. The RFautomatically shuts off during programming to prevent accidentaltransmissions on unintended frequencies. DO NOT HOLD THE RFBUTTON DOWN FOR MORE THAN ONE SECOND, or the unit will gointo sleep mode. In sleep mode, the unit is non-functional. Ifnecessary, recover from sleep mode by pressing and holding the RFbutton for more than two seconds.5. When power is applied, the transmitter will power-up to its last RFON/OFF state. Ensure that the green RF LED turns ON indicating theunit is transmitting. If needed, push the RF button to begintransmitting.The channel number LED also turns ON, representing the most recentchannel setting from the last time the transmitter was used.6. Put the vest on (refer to photos page 6). Tighten the Velcro side straps sothat the system components are held closely to the body. The rear flapof the vest should be hanging loose.7. Orient the camera on the Velcro for a proper (right side up) picture.8. Put the shirt on over the vest. Button the camera through theappropriate buttonhole in the shirt. (See photos right.)9. Test the system. Verify the camera is properly positioned by looking atthe receiver’s monitor. Walk quickly for a few steps, returning to themonitor. Make sure the camera’s field of view has not changed.Reposition if necessary. Double-check the camera picture and anglebefore the mission.Your Transmitter is now operational. Confirm its signal with yourPalladium Receiver.NOTE: The red ALARM LED typically indicates no video input.It could also indicate a hardware failure or low battery power.Button CameraThe camera position can be adjusted todesired button hole.Casual ShirtQUICK START

DTC COMMUNICATIONS, INC.8COMPONENTSTypical Palladium Operating TemperaturesA wide range of variables can affect the temperature of electronic devicesincluding ambient temperature, air flow, heat sink and mountingconsiderations. In a typical test performed at room temperature, thePalladium 100 has been observed to have a baseplate operatingtemperature of 37oC (99oF). In other words, it can get warm. The VidiVestPalladium has a special heat shield between the transmitter chassis andthe user to provide comfort in entended missions or in warmenvironments. Be sure this is properly installed before each mission.Using your Palladium 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 lastused channel and RF (ON/OFF) state. One of the green channel LEDs willturn ON indicating the active channel. If the video source (Camera) is notconnected, the ALARM LED will be ON.NOTE: Since the Palladium transmitter always returns to the lastconfiguration on power-up, the unit should always be deployed withthe RF switch ON. Therefore, once deployed, control of the unit mustbe restricted to applying and removing power. See the Quick Start(pages 4-5).Changing your Transmitter ConfigurationThe Palladium Transmitter can store up to 8 different configurations,which can be selected on the front panel. Each of these configurations canbe programmed into the Transmitter with the supplied DTC ProgrammingSoftware and a Windows PC. Refer to the Programming section on page 10for more information.To cycle through your preconfigured channels press the CONFIG buttononce to advance to the next setting. By default, the Palladium will turnOFF the transmitted signal while you are changing channels. This is toprevent accidental interference. Push the RF button after channel selectionto resume RF transmission of your video image.

DTC COMMUNICATIONS, INC.10PROGRAMMINGSystem PC Controller Application SoftwareAdvanced control of the system is available by using PC controlapplications. Typically users may want to customize the defaultconfigurations to control settings such as frequency, scrambling keys,modulation parameters, and video resolution.The transmitter is controlled by the application DTC_tx_ctrl.exeavailable on the CD delivered with the product.A PC is required with an open RS232 Serial COM port to configure atransmitter.Installation of the control program is as simple as copying it from the CDto a suitable location on the PC. No install shield routine is launched.Note that the application generates its own log and initializationfiles, so it is best to create a dedicated directory for theapplication, perhaps with a shortcut to the applicationfrom the desktop of the PC.AUDIO INPUT(S)FRONT PATCHANTENNAREAR PATCH ANTENNASPLITTERPROGRAMMINGCABLETo PC Serial RS-232 PORT9 AA BATTERY PACKGetting Started• Use the supplied programmingcable to connect the chosen COMport of the PC to transmitter to beconfigured.

DTC COMMUNICATIONS, INC. 11PROGRAMMINGTransmitter Control ApplicationOutput Frequency (MHz)The transmit frequency can be changed by entering the new desiredfrequency in this field. Values outside the range supported by a particulartransmitter type will be rounded to the highest or lowest supportedfrequency as appropriate. The resolution of the transmit frequency isresolved 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 configurationchange, the output always reverts to OFF. It must be ON for operation.Modulation FECThe default FEC is 2/3, however improved range operation can be achievedby selecting FEC 1/3. FEC 1/3 will improve signal range by 3dB. HoweverFEC 1/3 reduces link capacity to 1.2Mb/s.Modulation Guard IntervalThe Guard Interval is fixed at 1/16 in current firmware releases.Modulation BandwidthFor the Palladium transmitter products, the modulation bandwidth is fixedat 2.5MHz in current firmware release.COFDM ModeThe COFDM mode can be changed between QPSK and 16QAM. QPSK isthe default mode and will give the strongest most rugged RF linkperformance. Selecting 16QAM reduces the link performance by 5dB butimproves the link data throughput. Default values are shown in red.OFF2/31/162.5 MHzQPSK(your frequency)Advanced options are shown in blue. Theseoptions are for trained and experienced technicians only.
DTC COMMUNICATIONS, INC.12Output AttenuationThis control can be used to make minor adjustments to the output powerlevel, but in normal operation should not be changed from factory settings.(0 attenuation = full output power.)Video InputThis control is used to select the composite video input standard. Optionsare 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 whenChaining Input is turned off. This control can be used to set the videobitrate within the constraints of capacity available in the channel, but onlywhen Chaining Input is set to ON. Chaining CANNOT be enabled onnormal transmitters, and as such video bit rate control is automatic.Horizontal resolutionThe video coding resolution can be selected from 704, 528, 480 and 352pixels. For optimum performance, choose a resolution one step better thanyour camera’s resolution.Audio EncoderThe Audio can be turned ON and OFF with this control. Audio is OFF bydefault, but there are several audio modes that vary from very high qualityto speech grade that can be selected with this control. One or two channelaudio is supported. For optimum link performance, select the lowest audioquality necessary to support the mission.PROGRAMMING0NTSC1.1528OFFDefault values are shown in red.Advanced options are shown in blue. Theseoptions are for trained and experienced technicians only.
DTC COMMUNICATIONS, INC. 13Audio Input LevelThis control is used to define the audio gain to be applied to the audioinput signal. 0dB is used for line level audio and various options up to48dB of gain can be applied for microphone inputs. 3.5 VDC is applied atthe microphone connector for “phantom power” used to power electretcondenser microphones. Input impedance is 5K Ohms. The transmitterworks best with a high-impedance audio source.Unit NameEnter up to 16 characters to identify unit as desired.Sleep ModeThis control allows the unit to be forced into a Sleep Mode where mainfunctions are disabled, and the power consumption is significantly re-duced.DataFuture use.
