Note: This equipment has been tested and found to comply with the limits for a  
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are  
designed to provide reasonable protection against harmful interference in a  
residential installation. This equipment generates, uses and can radiate radio  
frequency energy and, if not installed and used in accordance with the  
instructions, may cause harmful interference to radio communications.  
However, there is no guarantee that the interference will not occur in a  
particular installation. If this equipment does cause harmful interference to radio  
or television reception, which can be determined by turning the equipment off  
and on, the user is encouraged to try to correct the interference by one or more  
of the following measures:  
LCD Projector

• Composite video – This output is always available, in addition to  
one of the other output choices. NTSC or PAL is selected by a rear  
panel DIP switch.  
What is the VSC 100?  
The Extron VSC 100 is a high resolution computer to video scan  
converter. It can convert computer scan rates up to 1152 x 900  
either from a Mac or a VGA (PC) source to NTSC/PAL, S-video  
and RGB outputs. The VSC 100 is installed between the computer  
and the desired display or output device (LCD or CRT projector,  
VCR or compatible video display or recording device).  
• S-video – A 4-pin mini-DIN connector provides output for S-video or  
Hi-8 style video. This is the highest quality recordable video output  
from the VSC 100 to an S-video VCR. The S-video output is  
selectable from the front panel.  
• RGBS – Use 4 of the BNC output connectors to provide red, green,  
blue and composite sync. This RGBS video output is selected  
through a front panel toggle switch and a rear panel DIP switch.  
Features  
The VSC 100 is designed for easy installation. The video input  
uses a “loop out” design, together with a single VGA-to-Mac  
adapter cable. Regardless if the application uses a VGA or a Mac  
video source, the VSC 100 allows the local monitor to be used.  
Connect the adapter cable one way for Mac and the other way for  
VGA. Connector type and gender prevent any mistakes.  
Installation procedures are in chapter 2.  
• RGBHV – Use 5 BNC output connectors to provide red, green,  
blue, and separate horizontal and vertical sync. A front panel switch  
selects RGB and a rear panel DIP switch selects “HV Out”.

There are four output formats available on the VSC 100. Connect  
the appropriate output cable(s) (composite video and/or RGBS/  
RGBHV or S-video) to the output device(s). See Figure 2-2a for  
output connectors.

___ Do not connect cables to outputs that will not be used for your  
application. This may load down the circuits and make the output  
signals weak. Composite video may be used with either RGB or  
S-video outputs, but not with both.  
Composite = NTSC/PAL A BNC connector provides either NTSC  
or PAL composite video, depending upon the position of the rear  
panel DIP switch. This output is always available, in addition to  
one of the other choices.  
For the best quality output, only use composite video when  
S-video or RGB inputs are not available. Use Extrons composite  
video RCA Cable (26-345-01male-male ), or equivalent, and use  
BNC/Male-RCA/female adapter if required (10-264-01).

S-video/RGB switch Set this switch for the type of output for your  
application: up for S-video or down for RGB.  
Signal Lock LED Off = no signal; Blinking = signal is out of range;  
On = signal is within range.  
Troubleshooting Tips  
No image or picture –  
1. Make sure all cable connections are correct and tight.  
2. Confirm that only compatible scan rates are coming into the  
VSC 100.  
Picture too bright –  
1. Set 75 Ohm DIP switch (rear) to the 75 Ohm position (up).  
Picture too dark –  
1. Set 75 Ohm DIP switch (rear) to the off position (down).  
2. Disconnect any output cables that are not being used.  
(Do not have cables connected to both S-video and  
RGB (R-Y/Y/B-Y) at the same time.  
No color on display screen –  
1. Adjust the hue/tint and color controls on the display device.  
2. Be sure to use video equipment that matches the format  
(NTSC, PAL etc.).  
Poor recording quality –  
1. Adjust the sharpness control on the VCR.  
2. Record using the S-video output of the VSC 100.
