  • Automatic reclocking and equalization
  • Control via front panel, Ethernet or RS-422/RS-485
  • Compact size, low power

Model 2444 is a rugged and compact, 4x4 matrix (crosspoint) switcher that can simultaneously connect each of its four outputs to any of its four inputs. It supports all single-link SDI standards: SMPTE 259M(C) (SD-SDI), 292M (single-link HD-SDI), and 424M (3G-SDI). Four seven-segment LED displays provide indication of the switch states, as well as signal status of the video inputs.

Simple and flexible control

The unit can be controlled manually through its intuitive front panel console, or with a computer through its Ethernet or serial communications interfaces. A built-in web server allows the unit to be controlled from any web browser, and its integral telnet server enables it to be easily controlled by a remote, automated client over a network.




The versatile switching fabric provided by Model 2444 can be used in a number of ways. For example, one input can be routed to two or more outputs to implement a video splitter. The unit can also be used to select alternate video sources on the fly in video editing applications and small broadcast studios.
