1 About the HDX-1100 The HDX-1100 Aircraft/Terrestrial High Power HD Video Transmitter (HDX-1100) (shown) is a lightweight and rugged transmitter that is suited for mobile and aircraft environments; able to withstand constant vibration, shock, temperature swings, and humidity. Common uses include law enforcement surveillance and video collection. The HDX-1100 supports H.264/MPEG-2 and HD/SD. The HDX-1100 can transmit DVB-T COFDM digital transmission (QPSK, 16QAM, 64QAM) consisting of a standard definition (SD) NTSC or PAL video signals or high-definition (HD) video signal (up to 1080i), plus two audio signals and an RS-232 data channel. The transmitter uses the MPEG-2 video compression format for high-quality imagery. The amplifier operates at 8W for all bands except 4940-4990 MHz which is limited to 1.0W maximum. Low power mode is typically 3 to 6 dB below the maximum rating. You can control the HDX-1100 with the touch screen user interface (see Section 3), or an optional remote control unit (RCU) (see Section 4). You also can configure the HDX-1100 with a PC using a web browser (see Section 5). 2 Operating in Safety Guidelines for safe operation are derived from OET bulletin 65, August 1997, as recommended by the Federal Communications Commission (FCC). WARNING High levels of RF power are present in the unit. Exposure to RF or microwave power can cause burns and may be harmful to health. Remove power from the unit before disconnecting any RF cables and before inspecting damaged cables and/or antennas. Avoid standing in front of high gain antennas (such as a dish antenna) and never look into the open end of a waveguide or cable where RF power may be present. The HDX-1100, operated without an antenna, will not create RF energy exceeding 1.0 mW/cm2, the FCC limit for exposure. Connecting an antenna to the unit greatly enhances the potential for harmful exposure, and you must maintain a certain distance from the radiator. The following table shows the Maximum Permissible Exposure (MPE) safe distances from the antenna. Antenna Gain (dB1) 0 2 3 5 11 Safe Distance (cm) 4 6 6 8 15 Safe Distance (in) 1.57 2.36 2.36 3.15 5.9 HDX-1100 User and Technical Manual 1
Note Hazardous RF radiation limits and recommended distances may vary by country. Observe all applicable state and federal regulations when using this transmitter. To perform calculations to understand the safe exposure margin (MPE), use the following formula suggested by OET 65. The calculations provided are for common antennas often utilized in the ENG environment. Calculating MPE EIRP = P * (10 ^ (G / 10)) = (antilog of G/10) * P P = RF power delivered to the antenna in mW G = Power gain of the antenna in the direction of interest relative to an isotropic radiator R = distance to the center of radiation of the antenna in centimeters S = MPE in mW/cm² (milliwatts per square centimeters) Conversions dBi to numeric gain = Antilog (dBi/10) Feet to centimeters = Feet * 30.48 Centimeters to Feet = cm * .0328 4 π = 12.57 User Input RF power delivered to the antenna = Watts Antenna gain (referenced to isotropic antenna) = dBi Distance from the center of radiation = Feet Calculation steps: 1. [P] RF power input. Watts to milliwatts = Watts * 1000 2. [G] Antenna gain dBi. Numeric gain = Antilog (dBi/10) 3. [EIRP] Multiply P * G 4. [R] Centimeters to feet = Centimeters * .0328 5. Square R 6. Multiply R² * 4π 7. [S] Divide (R² * 4π) into EIRP S = Power Density in milliwatts per square centimeters. Note At frequencies above 1500 MHz, S must not be greater than 1.

Power Density (mW/cm^2) The figure to the right is a typical graph for a Vislink HDX-1100 Transmitter and shows the permissible exposure distance for various antennas. Graphs and data will vary, based on the actual transmitter, output power, frequency, and antenna utilized. One plot provides the permissible output of the transmitter for digital modulation, and the other plot for analog modulation. 2 1.5 1 0.5 0 Maximum Permissible Exposure @ 200 milliWatts RF Power 0 0.5 1 1.5 2 2.5 3 3.5 4 4 .5 5 5.5 6 6.5 7 7.5 8 Distance in Feet 0dBi 2dBi 3dBi 5dBi 11dBi Vislink, in accordance with the requirements set forth by the FCC, provides this information as a guide to the user and assumes the users of this equipment are licensed and qualified to operate the equipment per the guidelines and recommendations contained within the product user guides and in accordance with any FCC rules that may apply. 3 Setting the HDX-1100 With the Touch Panel The touch panel screen on the front of the unit lets you control the HDX-1100 directly as described in the following sections. 3.1 Selecting a Preset The HDX-1000 recalls the most recently saved preset when it is powered up.

CHANNEL LCD Display PRESET Displays the current preset number. 4 HDX-1100 User and Technical Manual
Use a 9-pin RS-232 null-modem cable to connect the communication path between the RCU and the HDX-1100. A receptacle at the rear of the controller supplies DC power to the RCU. Vislink provides the 2-pin Weidmuller connector (Part # 52104-2) to connect to the power receptacle at the rear of the controller. The required power range is from +10—+50 Vdc (negative ground only). If the RCU displays a C in the preset window, the HDX-1100 has lost power or a communication error has occurred. If this happens, check the power and serial cable connections. 5 Setting the HDX-1100 with a PC To set up your HDX-1100 with a PC, do the following: 1.
