Extron electronic SW2 DVI A, SW4 DVI A DESCRIPTIONspecifications, Features, Application Diagram

DESCRIPTIONspecifications

The SW2 DVI A and SW4 DVI A are two and four input, one output, single link DVI - Digital Visual Interface switchers that allow multiple DVI input signals to be switched to one compatible display. These switchers are compatible with PC resolutions up to 1920x1200 @ 60 Hz, and also support HDTV 1080p.

To enhance and simplify integration, both models feature the EDID Minder that automatically manages the EDID information between the digital display device connected to the output and all the input sources. By maintaining continuous EDID communication with all sources, EDID Minder ensures all DVI sources power up properly and maintain their video outputs whether or not they are actively connected to the digital display device through the switcher's output. Front panel LED signal presence indicators provides a quick means of active signal verification.

Independent input equalization reduces the need for additional signal conditioning equipment by compensating for signal loss when using long input cable assemblies. Front panel switches allow user-selectable EQ levels. The SW DVI A Series switchers are user-configurable for manual or autoswitching modes. Autoswitching allows any input of the switcher to be selected automatically when the switcher detects a signal.

Convenient control options allow easy integration into a variety of environments. These options include front panel control, IR, RS-232, and autoswitching. To further simplify integration, both SW DVI A switchers are housed in compact, 1U, half rack width enclosures that are easily mounted into optional Extron 1U Universal Rack Shelf Kits.
