Pacific Microwave Research, Inc. DT-200 Digital Microwave Video & Audio Transmitter USER’S MANUAL Pacific Microwave Research, Inc. 1485 Poinsettia Avenue, Suite 111 Vista, CA 92083 760.295.5416 www.pmicrowave.com 2 IMPORTANT WARNING! THIS EQUIPMENT WILL POSE A RADIATION HAZARD IF IMPROPERLY HANDLED Pacific Microwave Research, Inc. (PMR), in compliance with RF exposures limits set forth in OET Bulletin 65 , Fourth Edition, August, 1999. 1 The following text is intended to notify the user of PMR’s transmitter equipment that a radiation hazard could exist if the DT-200S transmitter is improperly operated. The user should carefully read and understand this section before operating equipment. PMR’s DT-200S microwave transmitter is rated at 0.1W (+20 dBm) nominal RF power output and has been designed as an intentional radiator. The device can deliver video and audio signals over short ranges when used with PMR’s DR-200S receiver and appropriate antennas in either fixed or mobile applications. When the DT-200S transmitter is operating into an antenna, the system is emitting radio frequency energy! An internal RF isolator prevents emission of energy at the antenna terminal when no antenna is connected even when the transmitter is powered up. Because the DT-200S is an isolator protected low power device, there is no hazard potential until a proper antenna is connected to the RF output terminal. Safe operating procedures must be observed when the unit is transmitting into an antenna. Exposure is based upon the average amount of time spent within an electromagnetic field (RF energy) with a given intensity (field intensity in mW/ cm 2 ). There are two categories of exposure situations; occupational/controlled and general population/uncontrolled. Occupational/controlled limits apply in situations in which persons are exposed as a consequence of their employment provided those persons are fully aware of the potential for exposure and can exercise control over their exposure. These limits apply in situations when an individual is transient through a location where occupational/controlled limits apply provided the individual is made aware of the potential for exposure. General population/uncontrolled exposures apply in situations in which the general public may be exposed, or in which persons that are exposed as a consequence of their employment may not be fully aware of the potential for exposure or can not exercise control over their exposure. Exposure may be controlled by observing the safe distances found in the Table below and remaining beyond those distances from the antenna at all times when the transmitter is operational. At no time should the user remain within a distance less than the indicated safe distance for a period greater than 30 minutes. 1 The complete text may be found at: www.fcc.gov/bureaus/engineering_technology/documents/bulletins/oet65/oet65.pdf 3 The safe distance is based on the MPE exposure limits identified in Table 1. (FCC Limits for Maximum Permissible Exposure) of OST 65. The maximum power density allowed at 2400 MHz is 5 mW/cm 2 for occupational/controlled exposure, and 1 mW/cm 2 for general population/uncontrolled exposure. For fixed operations, based upon a maximum transmitter power output of 0.1W with an antenna gain of +2 dBi, the safe distance is greater than 4 cm from the antenna for both controlled and uncontrolled exposure. Exposure level is relative to antenna gain. Gain antennas (parabolic dish, horn, helical, Yagi, etc.) will increase the safe distance required. Table 1 indicates the safe distance for fixed operations, within the main beam of the antenna, based upon a maximum transmitter power output of 0.1W with an antenna gain of +2 dBi. Frequency – 2400 MHz TX Power – 0.1W (+20 dBm) Antenna Gain - +2 dBi Safe Distance from Antenna Under Fixed Conditions Controlled Exposure (5 mW/cm 2 ) Uncontrolled Exposure (1 mW/cm 2 ) 1.4 cm 3.2 cm If the DT-100S is operated at a fixed location and other transmitters are co-located, the user must consider exposure as a result of the aggregate collection of transmitters at the location. Increases of four times in radiated energy level will double the safe distance. The user must calculate the safe distance for any given case based on the antenna gain required for the application. Pacific Microwave Research can provide such calculations in consultation with the user if required. Contact PMR at 760.295.5416 for additional information. Table 1.

Operational Description of Pacific Microwave Research DT-200S Microwave Video/Audio Transmitter Introduction The DT-200S Microwave Video and Audio Transmitter from Pacific Microwave Research is a compact transmitter designed for short-range transmission applications under FCC Part 90 and Part 74. Common uses include law enforcement surveillance and electronic field production. The DT-200 is a compact unit designed for portable and field applications to transmit remote video to a central receive location. The DT-200S is designed to transmit one NTSC (or PAL) video signal plus two high quality audio signals. The DT-200S operates from a nominal +12 Vdc power source and is capable of 0.1Watts of output power. The DT-200S may be equipped with up to 10 channels consistent with parameters listed on the user’s FCC station license. Power Supply The DT-200S power supply is housed in a common housing with the transmitter and produces all required DC voltages for the operation of the transmitter. Nominal input voltage is in the range of +11 – +36 Vdc with a typical current consumption of 1.2 A @12Vdc. Primary power is applied to J3 Pin A with the return on J3 Pin C. Reverse polarity protection is provided by D2. Voltage regulator U9 regulates the primary input voltage to +5.0 Vdc for application to the microprocessor (U8), the RF power amplifier (U11), modulator (U16) and subsequent regulation. This +5 Vdc is then converted to 3.3 Vdc by U10 for application to the clock oscillator (U13). U12 converts regulated +5 Vdc to -5 Vdc for application to the video and audio amplifiers (U7, U22, U23, and U24). U14 converts the +5 Vdc regulated voltage to +15 Vdc for application to the phase-lock-loop (PLL U21) and loop filter (U20). Frequency Generation The output frequency of the DT-200S is generated by the combination of PLL (U21), loop filter (U20), and VCO (U17). The frequency of operation is loaded into the serial PLL by microprocessor (U8) according to the position of the selector switch (S1) or via RS-232 command (U11). The customer channel table is stored in the microprocessor (U21). Frequency data is input to U21 through RS-232 (U11) at the time of manufacture. A clock oscillator (U13) operates at a frequency of 16 MHz and provides primary frequency stability for the transmitter. The tuning voltage from U20 is applied to the VCO (U17). The output of U17 is sampled for input to the PLL (U21). The sample signal is compared to the desired frequency and an error tuning voltage is applied to U20 to maintain operating frequency. Video Modulation Video modulation is applied to the video encoder module through front panel BNC connector J4. The video encoder converts the analog video signal (NTSC or PAL) to an MPEG2 compressed digital video signal. The video signal is multiplexed into a serial data stream with the digital audio signal and transformed into a balanced quadrature signal consisting of in-phase (I) and quadrature-phase (Q) signals representing the COFDM waveform. The I/Q signals are applied to the modulator (U1) resulting in an 8 MHz wide digital signal. The output level of the modulator is maintained at a precise level by the combination of U2, U5, and U3. A voltage controlled step attenuator (U2) is controlled by the microprocessor (U8) through a digital-to-analog converter (U5) and dc amplifier (U3) to adjust the modulator level to the voltage-controlled-oscillator (VCO) as the operating frequency is adjusted. Temperature stability is maintained by U4. The leveled output of the modulator (U2) is applied to the VCO (U17). Audio Modulation Audio modulation is applied to U24 which acts as a balanced to unbalanced amplifier. Audio levels are controlled via the microprocessor (U8) by the digital attenuator (U22). The output of each audio channel is amplified by U23A:B and then applied to the audio encoder module. The audio encoder digitizes the audio and multiplexes it into a serial data stream along with the video signal as above. RF Amplification Modulated RF energy is output from the VCO (U17) and amplified by U18. This output is up-converted by application to a 2X frequency multiplier (U19) and subject to filtering by FL1 and additional gain by U25. The output of U25 is fed to the power amplifier board. The power amplifier board provides additional gain (U2) and filtering (FL1) prior to application to the final amplifier stage (U1). The RF output of U1 is applied to isolator ISO 1. This provides greater than 20 dB of isolation between the output device and the antenna. The isolator prevents reflections from poor antenna matches from entering the sampling circuit and causing PLL locking problems. Finally, the output is applied to a low pass filter with a cutoff frequency of 3300 MHz. This filter prevents the transmission of any harmonic signals that may have been generated in the transmitter as well as those that could be generated as a result of the non-linear characteristics of the ferromagnetic isolator. The output of the filter is connected to a front panel female SMA connector. In the event of a PLL unlock condition, the microprocessor (U8) commands the power amplifier (U1) to the standby condition to prevention the transmission of energy on a frequency not licensed to the user.
Exhibit pursuant to Human Exposure Guideline to Radio Frequency Energy and Warning Label affixed to DT-200S The following text is included at the front of the operating manual for the DT-200S to educate the users regarding Radio Frequency Radiation Hazards. Additionally, a warning label is attached to the DT-200S to direct the user to read and comply with the information contained in the user manual with respect to RF radiation hazards. IMPORTANT WARNING! THIS EQUIPMENT WILL POSE A RADIATION HAZARD IF IMPROPERLY HANDLED Pacific Microwave Research, Inc. (PMR), in compliance with RF exposures limits set forth in OET Bulletin 65, Fourth Edition, August, 1999. 1 The following text is intended to notify the user of PMR’s transmitter equipment that a radiation hazard could exist if the DT-200S transmitter is improperly operated. The user should carefully read and understand this section before operating equipment. PMR’s DT-200S microwave transmitter is rated at 0.1W (+20 dBm) nominal RF power output and has been designed as an intentional radiator. The device can deliver video and audio signals over short ranges when used with PMR’s DR-200S receiver and appropriate antennas in either fixed or mobile applications. When the DT-200S transmitter is operating into an antenna, the system is emitting radio frequency energy! An internal RF isolator prevents emission of energy at the antenna terminal when no antenna is connected even when the transmitter is powered up. Because the DT-200S is an isolator protected low power device, there is no hazard potential until a proper antenna is connected to the RF output terminal. Safe operating procedures must be observed when the unit is transmitting into an antenna. Exposure is based upon the average amount of time spent within an electromagnetic field (RF energy) with a given intensity (field intensity in mW/ cm 2 ). There are two categories of exposure situations; occupational/controlled and general population/uncontrolled. Occupational/controlled limits apply in situations in which persons are exposed as a consequence of their employment provided those persons are fully aware of the potential for exposure and can exercise control over their exposure. These limits apply in situations when an individual is transient through a location where occupational/controlled limits apply provided the individual is made aware of the potential for exposure. 1 The complete text may be found at: www.fcc.gov/bureaus/engineering_technology/documents/bulletins/oet65/oet65.pdf General population/uncontrolled exposures apply in situations in which the general public may be exposed, or in which persons that are exposed as a consequence of their employment may not be fully aware of the potential for exposure or can not exercise control over their exposure. Exposure may be controlled by observing the safe distances found in the Table below and remaining beyond those distances from the antenna at all times when the transmitter is operational. At no time should the user remain within a distance less than the indicated safe distance for a period greater than 30 minutes. The safe distance is based on the MPE exposure limits identified in Table 1. (FCC Limits for Maximum Permissible Exposure) of OST 65. The maximum power density allowed at 2400 MHz is 5 mW/cm 2 for occupational/controlled exposure, and 1 mW/cm 2 for general population/uncontrolled exposure. For fixed operations, based upon a maximum transmitter power output of 0.1W with an antenna gain of +2 dBi, the safe distance is greater than 4 cm from the antenna for both controlled and uncontrolled exposure. Exposure level is relative to antenna gain. Gain antennas (parabolic dish, horn, helical, Yagi, etc.) will increase the safe distance required. Table 1 indicates the safe distance for fixed operations, within the main beam of the antenna, based upon a maximum transmitter power output of 0.1W with an antenna gain of +2 dBi. Frequency – 2400 MHz TX Power – 0.1W (+20 dBm) Antenna Gain - +2 dBi Safe Distance from Antenna Under Fixed Conditions Controlled Exposure (5 mW/cm 2 ) Uncontrolled Exposure (1 mW/cm 2 ) 1.4 cm 3.2 cm If the DT-100S is operated at a fixed location and other transmitters are co-located, the user must consider exposure as a result of the aggregate collection of transmitters at the location. Increases of four times in radiated energy level will double the safe distance. The user must calculate the safe distance for any given case based on the antenna gain required for the application. Pacific Microwave Research can provide such calculations in consultation with the user if required. Contact PMR at 760.295.5416 for additional information. Table 1.
