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.

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.

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.
