INTRODUCTION The Handheld Video Transmitter The Handheld Video Transmitter is the latest innovation in tactical video reconnaissance and digital video transmission from DTC. First responders will find the HVT valuable for search and rescue, assessing threats, physical security, and disaster sites. The HVT is an essential tool for government, military, and law enforcement teams. Weighing only 5.5 pounds and completely portable, the HVT uses a Palladium digital transmitter and fits in a durable 9.8 by 9.
OPERATION Using your HVT Transmitter Follow the instructions given in the Quick Start section on pages 4-5. When power is first applied to the HVT, 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.
COMPONENTS Auto Iris The Auto Iris camera feature allows the device to automatically adjust for varying lighting conditions. This feature emulates the human iris, which opens in dark conditions to let in more light and closes down in bright light to prevent overexposure. The HVT camera will accomodate a wide range of ambient light from bright sunlight to near total darkness. You may notice a slight delay for the camera to adjust when moving between these conditions.
COMPONENTS ® Do not cinch the Velcro battery strap here or you could damage the PC board inside. Cinch the battery strap here. Channel LEDs These green LEDs, numbered 1 through 8, indicate the channel number currently selected. Each channel represents a set of preconfigured settings. Power Connector Battery Pack HVT Transmitter Control Panel, Located on Bottom Hirose Connector ALARM LED This red LED indicates a valid video signal is not present.
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...
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 transmit frequency may be entered in 1MHz steps. Modulation Output (same as RF button functionality) This control is used to turn on and off the RF output.
PROGRAMMING (As Desired) Advanced options are shown in blue. These options are for trained and experienced technicians only. NTSC 1.1 528 OFF Default values are shown in red. 12 DTC COMMUNICATIONS, INC. 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, greater than 0 attenuation = reduced power in 1 dB steps.
PROGRAMMING Audio Input Level Not applicable to this device. 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. OFF Data Baud Rate Future use. 1200 Chaining Input Future use.
PROGRAMMING (Ch. No.) OFF Current Config (same as display panel) This field reports the last loaded configuration number (1-8). Note that for the Palladium transmitter, changes applied after the configuration has been loaded are saved immediately into the current configuration. To select another configuration, enter number (1-8) then click Apply. Scrambling Scrambling is 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 upgrade. Change RS232 address – (future use). Write AES Key – opens a dialog box for entering a customer-selected scrambling key.
