2. Overview
2.1 Introduction
With the 2-Port and 4-Port Audio/Video Splitters, you can transmit audio and video
signals from one PC to two or four monitors and headphones located up to 213.2
feet (65 m) away at a maximum resolution of 640 x 480, or up to 32 feet (10 m)
away with a maximum resolution of 2048 x 1536. Use the splitters in test bench
facilities, data centers, help desks, and video broadcasting applications
(presentations, stock quotes, timetables, schools).
You can cascade the splitters up to two levels. Link up to three monitors and
headphones to the source PC using the AC650A-2 or connect up to seven monitors
and headphones to the source PC using the AC650A-4.
The splitters have easy-to-use front-panel select switches and support the VESA
DDC, DDC2, DDC2B standards (for video out Port 1).
Plus, the splitters are compatible with a broad range of video interfaces, including
VGA, SVGA, XGA, UXGA, QXGA, and multisync.
