2.3 Gigalink HDTV-Link Model 6292 System Architecture
Each full Gigalink HDTV-Link Model 6292 System consists of (1) transmitter and (1) receiver
module that must be aligned with each other during operation to maintain maximum signal
strength for error-free wireless connectivity. The receiver module is equipped with a receive
level Bar Graph indicator to simplify terminal alignment
Each Model 6292 system (link) is shipped as a matched transmitter/receiver pair. Each link
is 100% operationally tested with operating parameters recorded and kept on file at the HXI
manufacturing facility. Terminal pairing is accomplished through a simple serial number
format with the transmitter module identified by an even 4-digit serial number with the next,
higher, odd, number in sequence to identify its paired receiver module.
2.4 Maintaining Terminal Pairing
Because each system is tested and shipped as a “Link”, the original terminal pairing must be
preserved to establish and maintain traceability back to the original production acceptance
test results and recorded performance data. While pairing any Model 6292 transmitter with
any model 6292 receiver will result in an operational link such mixing of pairs will leave the
link operation unsupported by HXI technical support from lack of reference data.
All malfunctioning or defective systems should be replaced as links not as individual
modules. If a system is believed to be defective HXI Technical support should be contacted
for assistance and if necessary an RMA# for return/replacement of the defective equipment.

3. Pre-operational Planning
3.1 Pre-deployment Survey
It is recommended that users perform an onsite survey and complete pre-installation
planning prior to actual operation of the Gigalink HDTV system. Pre-operational planning
tasks include:
• Selecting appropriate locations for all equipment based on the location criteria (see
Section 3.1)
• Identifying and locating (as necessary) a suitable mounting structure (i.e. tripod) for each
terminal
• Locate necessary services (e.g., power source and cabling) that will be required prior to
the operation
• Obtaining any necessary permissions and verify regulatory and safety compliance.
• Verifying the type and configuration of any equipment to be used with the Gigalink
HDTV-Link system
• Determining the best terminal locations to provide unobstructed “Line of Sight” and
minimum separation of personnel from the transmit module antenna.
• Identifying additional tools and equipment, if any, that will be needed to support
equipment installation
It is also recommended that installers prepare sketches that show where all system
components will be located and how cables will be routed between components.
Pre-deployment planning is essential to avoid unanticipated problems and failures in system
operation during actual operation.
Radiation Exposure Warning
A minimum separation of 34cm (13.5”) must be maintained
between Transmitter module antenna and any individual to reduce
the risk of RF radiation exposure above permissible limits.

3.2 Location Criteria
Considerations for locating the Gigalink HDTV system include the following:
• Line of Sight. The location of the transceiver must have an unobstructed line of sight to
the opposite end of the link. Potential obstructions include but are not limited to the
following:
− Onsite Obstructions. The transmitter and receiver modules should be sufficiently
high and at a location such that the line of sight will not be compromised by
conditions or activities beyond the control of the operator. At a minimum, the line of
sight should clear the edge of any vertical and horizontal obstructions or areas
occupied by people by no less than 8’. Possible obstructions include Foliage,
Vehicles, or personnel moving through the RF Path.
− Obstructions across the RF Link. The line of sight across the RF Path must clear
all intervening obstacles. Any even a partial blockage of the RF signal may render
the wireless link inoperable.
• Mounting Surface. Each Gigalink Model 6292 transmitter and receiver terminal are
designed to be mounted to a standard tripod system. The tripods used must be sturdy
enough to support the weight of each terminal and stable enough to prevent terminal
movement during normal operation.
• Environmental Conditions. The Gigalink Model 6292 terminals are weatherproof but
not watertight. The terminals must be located away from standing water, severe rain
splash, or snow buildup.
• Regulatory Compliance and Permissions. The selected transceiver location must
comply with all applicable regulatory and zoning requirements as well as rules and
restrictions imposed by the location owner or manager.
Note:
The user is responsible for identifying and complying with all applicable
regulatory, zoning, or other restrictions and obtaining the necessary permissions
from the appropriate authorities and facility management prior to installation.

3.3 Interference Planning for Co-located Links
When more than (1) Gigalink HDTV-Link are deployed in the same general area, care must
be taken to prevent RF interference between links. It is especially important to provide
adequate physical or angular separation of the received signal paths at the receiver terminal
locations.
Figure 3.1 provides a guide of how to configure receive terminal locations to avoid RF
interference between co-located links.

4. Setup and Operation
4.1 Deploying the Transmitter and Receiver
The HDTV-Link transmitter terminal should be deployed near the associated video
production equipment (Camera) and the HDTV-Link receiver located near the Video editing
facility.
Both Terminals should be attached to suitable mounts or tripods based on earlier survey
instructions and aligned with the antennas facing in the direction of the opposing terminal.
Rough terminal alignment can be accomplished by sighting along the screws located on the
top of the terminal housing or by using the optional alignment scope.
4.2 Applying terminal power
Before applying power to the Gigalink HDTV-Link terminal, make sure the terminal power
switch is in the center “off” position.
12VDC terminal power is applied to the standard XLR4 Power connector receptacle located
on the right back-side of the terminal housing. The power cable should be inserted until the
locking tab engages. When power is present at the XLR4 connector receptacle, the Red
Line Power LED will light.
With power present to the HDTV-Link Terminal, the terminal power switch can be toggled to
the right to power the terminal on. When terminal power is on, the center red LED will
illuminate.
4.3 Power Indicators
Each Gigalink HDTV-Link terminal is equipped with (3) power indicators, one for line power,
one for terminal power and one for optional On-Board battery power.

4.4 Terminal Alignment
In order to establish a reliable RF link, both HDTV-Link transmitter and receiver terminals
must be precisely aligned. The HDTV-Link receiver terminal is equipped a Bar Graph display
to confirm terminal alignment and signal strength.
With both transmitter and receiver terminals powered on, slowly adjust alignment both
vertically and horizontally until the receiver Signal Bar Graph display reaches the highest
level. It is recommended that two operators work together by incrementally adjusting each
side until the maximum receive level is achieved.
The use of 2-way radios or cell phones will make this task easier. Figure 4.2 shows the
operation of the Receive level Bar Graph Indicator.
Figure 4.2 Receive Level Indicator
Low Indicated Receive level High Indicated Receive Level
4.5 Connecting Video Services
The Gigalink HDTV-Link Model 6292 is equipped to transport (2) independent feeds of
SMPTE292M composite Video/audio. Channels A and B can be operated independently or together
as necessary with no degradation to signal quality.
Two BNC connectors interface with the Video feed cable (Transmitter) or supply the Video feed
cable on the receiver side. All interfaces comply with the SMPTE 75Ω Coaxial cable standard for
maximum cable length if Belden Type 1694A cable is used.
4.6 Video Activity Indicators
Both the Transmitter and receiver Module are equipped with Video Activity Indicators to show active
interfaces. Active interfaces are indicated by a lighted LED above the interface connector. Figure
