ISIS Expands Critical Path Protection

(click thumbnail)ISIS HD-212The ISIS Group Inc., producers of video, audio, and signal management and processing technologies, is introducing their HD-212 at NAB2007. A 2x2 HD/SDI/ASI protection changeover switch, the HD-212 is ideal for use in transmitter inputs, network or satellite and cable head end procedures.

ISIS Group VP and Technical Director Robert Stillwaugh, explains the HD-212’s best-applied scenario: “Whenever there is a redundant signal, the HD-212 provides near-instantaneous switchover to a live signal if there is an interruption in the primary input. The 2x2 auto-senses HD, SDI, or ASI signals.”

This design offers flexibility, letting an operation start with the minimum configuration and enables the system to grow with field upgrades as requirements change. The 1 RU body can hold up to two power supplies and two processor boards; can have an optional Ethernet core processor loaded onto the main processor board; and offers connections for remote monitoring and control via a 9-pin ‘D’ connector.
