1Turn the computer and its monitor Off. Be sure that power is not applied to the VSC 100 at this time.

__ There is no power switch on the VSC 100. The AC power cord should be unplugged while connecting or disconnecting input/output cables.

Output Connections

2There 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 Extron’s composite video RCA Cable (26-345-01– male-male ), or equivalent, and use BNC/Male-RCA/female adapter if required (10-264-01).

S-video – A 4-pin mini-DIN connector outputs S-video or Hi-8 style video. This is the highest quality recordable video output for a VCR. Extron provides an S-video cable (m-m, 26-316-02).

RGBS – Use 4 BNC connectors for red, green, blue and composite sync. Set the HV Out DIP switch on the rear panel down.

RGBHV – Use 5 BNC connectors for red, green, blue, horizontal and vertical sync. Set the HV Out switch on the rear panel up.
