C058 AC160 units 3 5 lb 1 6 kg 2 Introduction Normally computers are designed to drive their VGA Video Graphics Array output to only one nearby monitor Often however circumstances call for VGA output to be driven to one or several monitors far away from the computer That s where our family of VGA Video Splitters comes in A typical application for one of these Splitters involves a PC simultaneously sending VGA output to its own monitor usually placed nearby and to as many as nine remote monitors located around the room or in another room up to 250 feet 76 2 m away This makes your Splitter perfect for conference rooms classrooms public information displays show exhibits and demonstrations For more about VGA Video Splitter applications see Chapter 5 If you need to hook up more monitors than one Splitter can accomodate you can cascade Splitters by attaching one or more secondary units to the MONITOR ports of the primary unit See Section 3 4 These VGA Video Splitters come in compact attractive desktop enclosures They are powered by an external power supply and draw no power from the sending computer Each Splitter can be located up to 6 feet 1 8 m away from this computer With bandwidths of 300 MHz these VGA Video Splitters can handle resolutions of VGA SVGA Super VGA XGA Extended Graphics Array or XGA 2 as high as 1600 x 1280 pixels at refresh rates as high as 75 Hz They support a variety of sy

13. rt CHAPTER 3 Installation 3 4 Cascading If you need to display your computer s VGA output on more monitors than a single VGA Video Splitter can handle you can always cascade Splitters You can connect secondary Splitters to the MONITOR ports on the primary Splitter with short DB15HD male to DB15HD male cables If you need any of these cables call your supplier Then you can plug as many as a hundred monitors into the MONITOR ports on the secondary Splitters If you ll be cascading Splitters we have several suggestions for maintaining image quality and reducing the complexity of your system e Begin connecting secondary Splitters to the highestnumbered port on the primary Splitter and work backwards from there For example attach the first secondary Splitter to MONITOR 8 the second to MONITOR 7 etc e Avoid connecting secondary Splitters to primary Splitters with fewer ports For example rather than attaching a ten port secondary to a four port primary use the ten port unit as the primary and retire the four port until you need to use if as a secondary e In general use as few Splitters and as short runs of cable as possible to reach all of your monitors e You can cascade to more than two layers of VGA Video Splitters that is you can begin plugging tertiary Splitters into the MONITOR ports of secondary Splitters when you run out of MONITOR ports on the primary Splitter However the more VGA Splitters that
