While extension capability has been built into matrix switchers, converters, and monitoring systems, there are still plenty of applications that make use of individual extension units and modules. The technology has also allowed different signals to be combined, extended, and separated.
The Adder Technology ADDERLink XDIP IP KVM got a series of upgrades last year. The receiver can now access 16 sources and the transmitter can broadcast to 256 receivers. Improved remote control, either via a RESTful API or HTTPS web browser, is designed to give users additional choice and flexibility with how they control their XDIP solution. Managing all endpoints through an API will reportedly help customers simplify configuration and maintenance. According to Adder, this level of interoperability, combined with new multicasting functionality, means the XDIP is the ideal solution to bridge the gap between KVM and video-over-IP. Customers can now take advantage of KVM functionality while delivering video and AV content around a large-scale installation, over an existing 1GbE network. Power over Ethernet support has also been made available in the US. At the same time, company also debuted an addition to the ADDERLink INFINIITY 4000 Series, the ALIF4000. Multigigabit Ethernet support has been added to provide customers with the ability to balance their video quality and bandwidth usage requirements by delivering 4K over varying network capabilities, from 1Gb/s to 10Gb/s. Integrated 1GbE ports reportedly enable easy delivery of 4K60 video over 1Gb/s copper links using 100m of standard Cat-5e or Cat-6 cable. Dual multigigabit or 1GbE ports can be teamed together for enhanced resiliency or improved video capability. Compatibility with the existing ADDERLink INFINITY range means the ALIF4000 can be phased into an existing network.
