3.1 Installation Steps

Follow these steps to install the VGA Video Splitter:
1. Place the VGA Video Splitter within 6 feet (1.8 m) of the computer.
2. Run the included video cable from the computer's VGA output to the
connector marked VGA IN on the rear of the splitter.
3. Connect your primary monitor (the one that was previously attached directly to
the computer) to the connector marked MONITOR 1 on the rear of the splitter.
4. Connect the additional monitor(s) to the remaining MONITOR connector(s)
on the rear of the splitter. You can use VGA extension cables to extend the
distance you can run to as much as 250 feet (76.2 m); see Section 3.3.
5. Plug the output cord of the included power supply into the jack marked
POWER on the rear of the Splitter.
6. Plug the power supply into an AC wall outlet. The Splitter's front-panel LED
should glow red to show that the unit is properly powered.
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.
For a standard application in which your remote monitor(s) are pretty much
interchangeable with your primary monitor (the one on MONITOR 1), move all
four switch positions to the "UP" setting; this will cause the Splitter to pass the
"ID bits" from the primary monitor through to the VGA adapter. Moving all the
positions to UP will not work for applications in which:
• there is no monitor on MONITOR 1;
• the primary monitor is connected to MONITOR 1 with a VGA extension cable
that doesn't carry the ID-bit leads;
• the primary monitor uses higher-grade video than one or more of the remote
monitors (for example, color VGA vs. monochrome VGA or high-resolution
XGA-2 vs. low-resolution VGA).
