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. DVB-T utilizes 2000 carriers to transmit video and two channels of voice and data. Palladium II transmitters may be located on adjacent channels without a guard band. AES 128-bit encryption ensures users of secure communications. The Palladium 100 is a small transmitter with a 100 mW RF power output. This unit is ideal for concealments and shorter range robotic and UAV applications. The package is only 4.2” x 2.6” x 0.65” (approximate dimensions not including connectors). Power consumption is 7.5 Watts. Operation time on a fresh set of Lithium batteries is approximately three hours. All connections are conveniently located off the ends of the unit. Many users will want to power this device with disposable batteries. Palladium II VIDEO TX Palladium Pd2-TX-100 100-Milliwatt Digital Transmitter DTC COMMUNICATIONS, INC. NOTE: Use only Lithium batteries with this device. 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. 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 rotate the knob to the next setting. DTC COMMUNICATIONS, INC.

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... command. The transmitter is controlled by the application DTC_tx_ctrl_v1_3.exe (or higher) available on the CD delivered with the product. •Connection with a transmitter should be automatic, but the user can force selection of the correct COM port using the drop down, followed by the Connect button. •Select the channel to be configured from the unit’s front panel Channel Switch. A PC is required with an available RS232 Serial COM port to control the transmitter. Installation of the control program is as simple as copying the file 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 files, so it is best to create a dedicated directory for these applications, perhaps with links to the applications from the desktop of the PC. PROGRAMMING CABLE to PC SERIAL RS-232 PORT •Click Refresh in the application to display the current configuration. TELEMETRY •Update the current settings in the application, then click Apply to save to memory. Power Option CHANNEL Audio Palladium II VIDEO TX 10 AA BATTERY PACK 10 DTC COMMUNICATIONS, INC. Battery Pack Antenna 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. The DVB-T compliant mode requires a bandwidth setting of 6, 7 or 8 MHz. The narrowband mode bandwidth is either 1.25 or 2.5 MHz. Narrower bandwidths increase receiver sensitivity and extend the maximum distance of the link, however video quality and latency will suffer. Normal default for good quality video is 2.5MHz. The modulation bandwidth may be set to 1.25 MHz, 2.5 MHz, 6 MHz, 7 MHz, or 8 MHz. Modulation Output This control is used to turn ON and OFF the RF output. It must be ON for operation. Turn the transmitter RF power ON by selecting ON and Apply from the application. Narrowband FEC Narrowband FEC sets the forward error correction rate in the narrow bandwidth modes of 1.25 or 2.5 MHz. Tthe two rates are available are 1/3 and 2/3; the normal default setting for good quality video is 2/3. Changing the FEC rate to 1/3 will extend the receiver sensitivity by 2 to 3 dB at the expense of degraded video quality and longer latency. Narrowband Guard Interval Narrowband guard interval is used in the narrowband modes of 1.25 and 2.5MHz to adjust for varying multi-path delay conditions. The default is 1/16 however 1/8 can be selected if necessary to deal with extreme multi-path delays on long links. Selecting 1/8 guard interval could cause a degradation in video quality and latency. Narrowband Modulation Narrowband modulation is used in the narrowband modes to select between QPSK and 16QAM modulation. For best range with good video quality, QPSK is used; 16QAM will give better video quality but will cut down the link range by approximately 50%. DTC COMMUNICATIONS, INC. 11 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. Use the smallest guard interval that will allow reliable low error rate communications, this parameter may need to be adjusted when the link is relocated; the recommended default is 1/16. DVBT Modulation DVB-T modulation selects the modulation used in the wideband DVB-T mode. Modulations QPSK, 16QAM, or 64QAM can be selected. QPSK will give best distance and in most cases very good video quality and low latency. DVBT Spectrum Inversion DVB-T spectrum inversion allows flipping the modulated spectrum to compensate for spectrum inversion that may take place on the receiver side due to high side LO injection. DVBT 4 KHz Offset DVB-T 4 KHz offset is not normally used but might improve BER in cases where the TX upconverter I/Q balance is poor. 12 DTC COMMUNICATIONS, INC. 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. Output Power Output power selects one of two output power attenuator settings; low power or high power, typically the low power setting is the larger of the two attenuator settings and is used, for instance, if a power amplifier is added to the transmitter and the output power needs to be lowered substantially to prevent overloading the input of the power amplifier. Output Attenuation (dB) Output attenuation (dB) is the high power attenuator setting. 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, greater than 0 attenuation = reduced power in 0.25 dB steps.) Output Attenuation low (dB) Output attenuation low (dB) is the low power attenuator setting. DTC COMMUNICATIONS, INC. 13 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. MPEG4 Encoding Mode MPEG4 encoding mode selects the characteristics of the MPEG4 compression. Options are: low delay interlaced, standard delay interlaced, low delay progressive, standard delay progressive, and SIF. Interlaced scanning is what is used in conventional over-the-air video. Progressive scan is available on some cameras and involves scanning an entire frame in one pass rather than two in interlaced scanning. SIF is a bandwidth-conserving camera scan mode that cuts resolution in half in both the horizontal and vertical. MPEG4 Frame Rate MPEG4 frame rate selects the frame rate used in the MPEG4 mode, full frame rate is 30 fps for NTSC and 25 fps for PAL a frame rate of 1/2 or less has to be used in 1.25 MHz bandwidth mode. Options are: Full, 1/2, 1/4, 1/8. or 1/24. Video Bitrate (status only) Video bitrate is a status window that will display the video transport data rate, this varies with bandwidth, modulation, FEC rate and guard interval. The rate will increase with bandwidth and higher levels of modulation, it will go down as the FEC rate and guard interval are increased. The video bit rate will also decrease as other service options are activated such as audio and data channels. As a rule video quality and latency improve as the bit rate is increased. Horizontal Resolution 14 DTC COMMUNICATIONS, INC. Horizontal resolution determines the maximum number of horizontal Pixels that can be sampled by the video encoder. For optimal performance this setting should be set to the first value that exceeds the horizontal resolution of the camera in use. Options are: 352, 480, 528, 704 pixels. 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. Audio Input Level Audio input level selects the audio preamp gain level, options are: 0 dB, 12 dB, 24 dB, 36 dB, 48 dB. Use 24 dB for DTC supplied microphones. Note: 3.5 VDC phantom power is at the microphone input for powering electret condenser microphones. Unit Name Unit name allows the user to enter a name (up to 8 characters) for the transmitter that will be stored in memory. Sleep Mode Sleep mode shuts down most functions in the transmitter except the control functions. This can be used to conserve battery power and yet allow the transmitter to become active again with a simple command. Data Data allows activation of the RS232 half duplex serial data channel and to select parity mode. Data Baud Rate Data baud rate selects data channel baud rate, standard rates between 1200 and 115,200 baud are available. DTC COMMUNICATIONS, INC. 15 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. Chaining Output Chaining output (not normally used) assigns the output of the video encoder to the chaining port. Normally OFF. Current Configuration Current config indicates the preset that is currently being programmed or viewed, this should be the same as the preset selected by the channel switch. Scrambling Scrambling selects 3 different scrambling options: OFF (no scrambling), AES128, AES256 (optional), or ABS (a proprietary 32 bit scrambling algorithym). Heartbeat Enable Heartbeat enable activates a beating heart on the screen video graphic to indicate that a link is still functioning even if there is no motion on screen. 16 DTC COMMUNICATIONS, INC.
