RS-44SDI 4x4 SDI Switcher

RS-44SDI Front View


The RS-44SDI is a 4 input by 4 output digital video routing switcher supporting the SDI Serial Digital Interface (4fsc, 4:2:2) video format.

Any of the 4 inputs may be connected to any of the 4 outputs under local pushbutton control, via RS-232/RS-422 serial commands, or by using the remote control switch connections. Remote control panels are also available.

The switcher features automatic cable equalization and data/clock recovery for all video inputs, the capability to drive up to 300m of coaxial cable from any output, and a composite reference video input.

The system is housed in a 1 rack unit (1 RU) enclosure.
