The VS-211HDxl has two inputs and two outputs and it is compatible with SDI (SMPTE 259M), HD-SDI (SMPTE 292M) and 3G HD-SDI (424M) signals with or without embedded audio. Either of the two inputs can be manually switched via contact closures to the outputs or the unit can be set to switch automatically. A switch on the unit can be set to indicate which input is the primary input.
If the unit detects a loss of signal on the designated primary input, it switches automatically to the secondary input. When the unit detects the presence of the primary signal it automatically switches back to the primary input. The unit has two identical outputs for distribution to two destinations simultaneously.
The VS-211HDxl is compatible with ASI signals. When using the VS-211HDxl with ASI signals, it functions as a two input, single output switcher only. The switcher is housed in a compact Kramer DigiTOOLS enclosure and it has a maximum data rate of 3Gbps along with LED indicators to show the active input.
