Model 6292-2 User Manual # 6932 Rev. B HXI, LLC 22 Parkridge Road Haverhill, MA 01835 (978) 521-7304 www.hxi.com 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.

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.

B HXI, LLC 22 Parkridge Road Haverhill, MA 01835 (978) 521-7304 www.hxi.com 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.

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. Figure 4.1 Power Indicators
Model 6292-2 User Manual # 6932 Rev. B HXI, LLC 22 Parkridge Road Haverhill, MA 01835 (978) 521-7304 www.hxi.com 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 4.3 depicts normal operation of the Video Activity Indicators.
