Live-Link™ Jr. is a highly-integrated camera extender system optimized for electronic news gathering (ENG), uplink truck, and specialized broadcast applications. The portable camera end unit and rack-mounted truck end unit provide all the resources needed for a single-camera live event. Linked using just two single-mode optical fibers, the same excellent performance will be supplied whether the units are hundreds of feet or miles apart. Notable features of the Live-Link Jr. system include performance flexibility, support for high-quality on-air (program), talent cue (IFB) and intercom audio, and ease of use.
Camera End Unit Details
The Live-Link Jr. camera end unit is housed in a lightweight aluminum enclosure with an integrated carry handle. Weighing less than 6 pounds (2.8 kg) it is well suited for portable applications. As with the truck end unit, all camera end unit input and output signals are interfaced using standard connectors. A combination of status LEDs and multi-LED audio level meters are provided for operating and troubleshooting assistance.
The camera end unit can be powered from up to three sources. A 4-pin XLR connector on the front panel allows an external 12 Vdc nominal power supply to be connected. A battery mount, located on the back of the unit's cover, allows use of a broadcast-standard rechargeable battery. The standard battery mount is compatible with batteries from Anton/Bauer®. As an option a V-Mount battery mount can be provided.
A third input power option is available to Live-Link Jr. camera end units that are ordered with the Neutrik opticalCON DUO connector. As previously mentioned, this connector supports two fibers along with four metallic conductors. The camera end unit can be powered by a 10-50 Vdc source that enters the unit via the metallic conductors. This method allows the use of hybrid fiber/copper fiber assemblies to both interconnect the SDI signals and provide power to the camera end unit. A variety of fiber/copper cable assemblies can be used. For example, one major vendor offers a tactical-grade cable that has two 16 AWG copper conductors along with two single-mode fibers. Using a readily-available 48 Vdc power source located at the truck end, along with this type of "TAC" cable, an interconnect distance of over 1000 feet (308 meters) is possible. It's also possible to use SMPTE Hybrid type of fiber/copper cable assemblies to link the truck end unit to the camera end unit. The only caveat would be the need for opticalCON DUO connectors to mate with the camera end unit.
It is important to note that while the Live-Link Jr. camera end unit can be powered by hybrid fiber/copper cable assemblies the unit will not provide a power source for connected cameras or related equipment. The camera end unit is not capable of converting the 10-50 Vdc input into 12 Vdc for use by other equipment.
