CHAPTER 2: Introduction 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.
VGA VIDEO SPLITTERS 3. Installation 3.1 The Complete Package You should have received all of these things with your Splitter order: • (1) VGA Video Splitter of the appropriate model • (1) External transformer (power supply) • (1) 6-ft (1.8-m) DB15HD-male-to-DB15HD-male video cable for connecting the computer’s VGA output to the VGA Video Splitter • (1) Copy of this manual If any of these items are missing, call your supplier right away.
CHAPTER 3: Installation 7. The four-position DIP switch marked MONITOR TYPE on the front panel of the VGA Video Splitter tells the VGA adapter in your computer what type of monitors you have connected when the computer boots up.
VGA VIDEO SPLITTERS 3.3 Extending Your Distance The maximum distance to which a VGA Video Splitter can drive signals to a VGA monitor depends primarily on the quality of the cable being used and the pixel resolution and refresh rate of the VGA image coming from the computer. Never use twisted-pair cable as video-extension cable, because this will cause “ghosting” of the on-screen images. Table 3-1 below is a guide for maximum distance at various resolutions with high-quality VGA extension cable. Table 3-1.
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.
VGA VIDEO SPLITTERS 4. Operation The VGA Video Splitters provide a reliable means of getting your VGA images to widespread arrays of monitors: They use equalized amplification to compensate for the normal signal losses that occur when you run cable to VGA monitors at longer distances. With this technique, the signals that reach the monitors closely match the signal that left the VGA adapter, and you get the truest representation of your VGA images in terms of detail and color fidelity.
CHAPTER 5: Applications 5. Applications VGA Video Splitters are used where a number of monitors need to be connected to one computer. Typical applications would include classrooms, business meetings, and trade shows. In a conference room or demonstration room, for example, the VGA Video Splitter can feed images to the PC’s own VGA monitor plus others located around the room or on the demonstration table. This eliminates the need for people to crowd around the PC for a look at the display.
VGA VIDEO SPLITTERS 6. Troubleshooting 6.1 Common Concerns If the display colors on all the monitors seem to be “reversed,” this might be caused by improperly setting the MONITOR TYPE DIP switch on the front panel. Recheck the switch setting (see Section 3.2, step 7). If one or two colors are missing on one of the VGA monitors, make sure all connections to the VGA Video Splitter are secure. Make sure the monitor connector’s jackscrews are tightened. If problems persist, call for technical support. 6.
