1 About the HDX-1100
The Kamelyon
TM
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
TM
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/cm

,
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.
