HD-212 General description The RJM HD-212 functions as an input transfer system that can switch between two high definition or SDI digital video input signals, A and B. This is accomplished automatically using the internal signal detect, or manually using either the local or remote select A/B switch.

When power is applied, the A signal input is selected as the default mode. The output of the HD-212 can be either the A or B input. There are three 75 BNC connectors for the On-Line output and one BNC connector for the Off-Line output.

It is also recommended that, if possible, one rack-unit of space be left above the unit. Unless specified at the time of order, the HD-212 is shipped from the factory for nominal 117VAC 60Hz power. The unit comes shipped with a 120V type AC plug.
The HD-212 can automatically detect whether the input signals are HD or SDI. A 4-pin jumper (JP1) (JP1) (JP1) is provided to allow the unit to automatically or manually set (JP1) the standard. If the jumper is placed between pins 1 & 2, the standards detection will be automatic.

Power Supply / Regulators: Power Supply / Regulators: Power Supply / Regulators: Power Supply / Regulators: The unregulated voltage to the voltage regulators on the main board comes from either of two power supplies that can be removed at the front of the RTU frame for service and replacement.
Ethernet Interface Ethernet Interface Ethernet Interface A core processor is included to allow the HD-212 to communicate through an Ethernet interface to an external control device. This communication allows for status monitoring and switchover control. The installation consists of installing the processor sub-module into the mating connector on the HD-212 with the RJ-45 facing forward.
