1 About the HDX-1100
The KamelyonTM HDX-1100 high power digital
microwave transmitter is a ruggedized unit
designed to support high quality video and data
transmission in airborne and mobile applications, where
vibration, shock, humidity, and temperature swings
are everyday occurrences. The HDX-1100 is compliant
with aircraft industry mounting standards, making it
perfectly suited for airborne or ground based
mobile platforms. Typical applications include real
time video for law enforcement, public safety, fire,
utility, and other agency based surveillance tasks.
The HDX-1100 includes an H.264/MPEG-4
encoder that provides standard or high
definition (SD or HD) video on DVB-T/
COFDM, or Vislink RangeMasterTM single
carrier modulation. An MPEG-2 encoder
option is available to support legacy
receivers.
Video inputs may be configured for
composite NTSC or PAL in standard analog
formats, or digital video in SDI, HD-SDI, or
ASI formats. Other inputs include two full
range audio channels, and an RS-232 data
channel.
The transmitter RF output is 8W in high power mode, and about 4 W in low power mode.
The HDX-1100 may be operated via the touch screen user interface (see Section 4), however it
is typically controlled by an optional aircraft remote panel (RCU) (see Section 5). Initial HDX-1100
programming and presets should be configured via PC using the integrated web browser utility
(see Section 6).
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.

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 used
in the mobile microwave 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.

NOTE: There is a 10 AMP DC circuit breaker on front panel of HDX-1100. If the power to this
breaker is fed from another circuit breaker in the aircraft, the HDX-1100 breaker should be left in
the on position. To operate the breaker: push in = ON, pull out = OFF, a manual reset is required
after the breaker trips.
HDX-1100 MECHANICAL OUTLINE
There are two possible mounting configurations, which should provide an installer with enough
flexibility to work in most situations:
1) For situations where the transmitter will be mounted on a flat surface, four captive nuts
have been installed in the transmitter side plate.
2) An optional aircraft mounting kit (part # 9000372) may be ordered. The kit includes an
ARINC compliant low profile tray with quick release clamps, and removable spacers.

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).
NOTE: During initial power up, the RCU will display a C until the HDX-1100 processor
completes a boot up and self check sequence; this is normal. If the C does not disappear
within one to two minutes, the HDX-1100 has lost power or a communications error has
occurred; check the circuit breakers, and power and serial cable connections.
To facilitate updating or servicing an HDX-1100 transmitter, we recommend that the
transmitter and RCU panel are fed from different circuit breakers. In normal operation, power
should be applied to the RCU first, or to both units simultaneously. To use local (front panel)
control of the HDX-1100 transmitter, the RCU should be off (not powered) when the
transmitter is first powered up. The RCU always has priority, and will assume control if power
is applied while the transmitter is on and in local control mode. At the same time, the front
panel will freeze and be non-responsive even though the RCU is functioning perfectly. To
return to local control, turn both units off, and re-boot only the transmitter.

18
Submit button when you are satisfied with the result. Next, click on the
Modulation button in the menu bar at the top of the screen.
MODULATION SETUP SCREEN
Modulation setup determines the bit rate that the transmitter can send to
the receiving station for each preset. Lower bit rates will work better in
situations where extreme fades, interference, or multipath are present.
Higher bit rates are not as robust; however, they may be required for
highest quality HD transmission.
The maximum available bit rate is directly related to the modulation type
and the channel bandwidth. The following tables provide a complete
summary of modulation settings for both 6 and 8 MHz DVB-T bandwidths
as a function of bit rate. In order to comply with FCC emission standards,
a 6 MHz DVB-T bandwidth is the maximum allowed in an 8 MHz wide RF
channel, while an 8 MHz DVB-T bandwidth can be used in a 10 MHz or
wider RF channel. A 10 MHz DVB-T bandwidth can support a total bit
rate 33% higher than an 8 MHz channel, if all other factors are equal.

![](/img.php?id=1520078&img=bg16.png)
20
NOTE: External encoder required for bit rates in yellow highlight.
Other factors that impact the total available bit rate are the code rate
and the guard interval settings.
Coding Rate Setting: This setting determines the amount of forwa rd
error correction used to reduce video data loss under adverse conditions .
If the code rate is set to ½, this means that half of the available data rate
is being used for error correction, while the rest is available for video. A
code rate of 1/2 uses the most bandwidth for error correction, but
provides the highest degree of protection against video breakup.
Guard Interval: The primary purpose of the guard interval is to provide
resistance to multipath and co-channel interference. Longer guard
intervals are used in dense metro areas, where high levels of multipath
are expected. A guard interval of 1/4 is the longest, while 1/32 is the
shortest.
NOTE: W hen programming an HDX-1100, a good rule of thumb is to
program several presets with varying amounts o f error correction to be
able to quickly switch quickly from a very robust, low data rate setting, to
a less robust but higher-speed setting.
6.5 VIDEO AND AUDIO INPUT SETUP
The video and audio inputs must be configured for each preset. To initiate this procedure,
click on MPEG-2 or MPEG-4 in the bar at the top of the screen, and then click on Video on
the left side of the screen. Two dialogue boxes will appear: Video In, and, Encryption.
See next graphic for details.
IMPORTANT: When equipped with the MPEG-2 encoding option, HDX-1100 presets may
be programmed all in MPEG-2 mode, all in H.264/MPEG-4 mode, or as a mix of the two. For
example, the first five presets may be programmed for MPEG-2 encoding, while the
remaining four are programmed for H.264/MPEG-4 encoding.
Video Settings: Click on Video In and select the desired parameters from the drop
down table. Available parameters include the input configuration, such as composite or
SDI, as well as video resolution. MPEG-2 settings differ from MPEG-4 settings, and
require additional choices to be made, including
NOTE: Input A is the normal video input and must always be set up. When using the
![](/img.php?id=1520078&img=bg17.png)

9 Local System Access and Management Interfaces
The front panel of the HDX-1100 includes an LCD touch screen that allows radio operating
parameters to be initially configured and later modified by maintenance personnel. The
touch screen provides the ability to recall and review and/or change the frequency of
channel presets, turn the power amplifier on and on, switch between high power and low
power modes, and gives visual feedback to maintenance personnel for each of the
described actions. Future software updates will provide additional set-up capability,
including the ability to set modulation constellation, guard interval, and Forward Error
Correction, and will support saving any changes to a selected or new preset.
NOTE: The HDX-1100 touch screen will allow local control only when the remote control
(RCU) panel is disconnected, or powered down. If the RCU panel is turned on or
connected while the HDX-1100 is powered on, the RCU will take priority for as long as the
units are powered on. The local touch screen will continue to display the last setting, but
will not longer control transmission parameters.
To regain local control, the HDX-1100 must be powered down, and the RCU must be
turned off or disconnected, before powering up the HDX-1100 again.
Once the boot-up sequence is completed in local control mode, the main screen will be
shown, as illustrated in 8.1 below.
