The ISIS Group has introduced the HD-212, a 2 x 2 HD/SDI/ASI protection changeover switcher.
The unit is well suited for use in network, transmitter inputs or satellite and cable headend operations. The HD-212 detects signal presence on both its A and B inputs and transfers to the offline input upon failure of the primary feed.
For added protection, it provides relay bypass protection of the A input to the main online output in case of power failure or processor board removal. The return-to-A function provides for automatic return to the primary input signal upon its restoration.
The 1RU enclosure can house up to two processor boards and two power supplies. An optional Ethernet core processor is available.
