INPUT / OUTPUT COMPATIBILITY

VGA / SVGA / XGA Compatibility - The unit features 15-pin HD VGA-type connectors for input and outputs. The units will directly connect to VGA video cards and display devices using the IN8000

Series of VGA extension cables, available in a variety of lengths from 3’ to 100’. Longer lengths are available by custom order.

MAC / SUN / SGI / Workstation Compatibility - While the IN3264 / IN3268 is primarily designed for VGA-type video cards and monitors, this distribution amplifier actually has 6 discrete amplification paths and is capable of amplifying analog video signals in a variety of sync formats including RGBHV, RGBS, RGsB, and RGBHVS. The IN3264 / IN3268 can connect to MAC, SUN, SGI and other high- resolution workstations and monitors by using input and output adapter cables (see list on page 7).

VGA, SVGA, XGA, SUN, SGI and other workstation video cards operate in several different modes encompassing a wide range of resolutions and horizontal and vertical scan rates. The IN3264 / IN3268 is not a scan converter and the display devices attached to the outputs must be compatible with the resolution, horizontal scan rate and vertical refresh rate output of computer video card. Please check the documentation for both the computer video card and the data projection device in order to ensure compatibility.

This section offers step-by-step instructions for installing the IN3264 / IN3268.

1.Turn the computer and computer monitor off. Disconnect the computer monitor (if present) from the video output port on the computer.

2.Connect an input cable between the computer video port and the IN3264 / IN3268 input using the appropriate cable as indicated in the chart on Page 7.

3.Connect the local computer monitor (if present) to Output #1 on the IN3264 / IN3268 distribution amplifier. VGA local monitors can be connected directly to the output. Other types of local monitors are connected using the appropriate adapter / extension output as indicated in the chart on Page 7. If no local monitor is connected to Output #1, you can emulate a VGA color monitor / MAC 13" RGB monitor using the dip switch located on the bottom of the unit.

4.Connect output devices (monitors, data projectors, etc.) to the other IN3264 / IN3268 output connectors. Devices may be connected directly to the outputs, or you may use the appropriate adapter / extension output cables as indicated in the chart on Page 7. For best results, high-resolution coaxial cables are recommended for all output connections. Note: All unused outputs are self-terminating and do not require a termination plug.
