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 RangeMaster
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

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.

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.

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.

3 Installing an HDX-1100 Transmitter

The HDX-1100 is built in an ARINC compliant 3/8 ATR housing, and was designed primarily
for aircraft operation. It is also suitable for general mobile applications, including terrestrial
vehicles. The transmitter and its remote control panel (RCU) have been tested and certified to
be compliant with RTCA DO-160F, as recognized by the FAA and other global agencies that
regulate aircraft operation and safety. NOTE: Aircraft installation must be performed by
certified aircraft maintenance personnel.

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.

The optional 9000372 3/8 ATR mount includes a set of spacers that may be installed if
clearance is not sufficient to allow the clamps to disengage. The spacers would not be needed
if the mounting plate is attached to a shelf within the airframe, as shown below.

4 Controlling the HDX-1100 with the Touch Panel

The touch panel screen on the front of the unit lets you perform routine setup and
maintenance functions and control the HDX-1100 directly as described in the following
sections.

NOTE: To use the HDX-1100 front panel controls, the RCU panel must be turned off or
disconnected prior to turning the HDX-1100 on.

4.1 Selecting a Preset or a Channel

The HDX-1100 recalls the most recently saved preset and channel when it is powered up.
You can select from up to nine preset configurations. The last four are configured as factory
defaults, but may be changed to suit your needs. Up to 15 RF channels may be configured
To select a preset, do the following:

1. Press the UP or DOWN buttons below the PRESET bar in the display

2. The new PRESET selection will remain so until it is changed.

3. Press the UP or DOWN buttons below the CHANNEL bar in the display

4. The new CHANNEL selection will remain so until it is changed.

4.2 Selecting the RF Output Level

The HDX-1100 recalls the most recently saved RF output power level when it is powered up. To
select between high or low power for the RF output level, do the following:

1. Press PA HIGH/LOW key to toggle between HIGH or LOW RF output level.

2. Press the PA ON/OFF button to toggle between RF on and RF off.

NOTE: When changing channels, the PA will automatically shut off to avoid interference
with other users, as the frequency changes. It must be manually turned on again once
the frequency change is complete (the display will change to new channel selection).

Please refer to section 8 for complete information on using the local touch screen controller

5 Setting the HDX-1100 with the Aircraft Remote Panel

You can install the Aircraft remote control unit (RCU) up to 50 feet from the HDX-1100 using a
3-wire serial interconnection and a power source. The following figure shows the RCU.

Remote Control Unit – Part Number 907621-6

When the remote panel and HDX-1100 are powered up at the same time, the remote takes
priority and the HDX-1100 local touch screen will not have any menu items shown, and will
appear as the in the photo below.

The following table provides detailed descriptions of the functionality of each push button and
rotary switch, plus an explanation of each LED. Presets and channel numbers are both
shown in LCD window displays.
