stereo hardware installation
The following steps are recommended for installing stereo hardware
packages for use with a multi-channel hp visualization center sv6
solution. The same principles apply to single channel configurations.
1. Unpack and inventory components
Emitters should have a stereo-sync BNC type connector and a 9-pin
D-sub connector for the separate power transformers. BNC coaxial
type cables are necessary for signal transfer between the graphics
card and the emitters. BNC “T” connectors are often used to split
stereo signals from the controller card on the compositor to several
emitters.
2. Ensure eye wear is functioning and clean
Follow the manufacturer’s suggestions for cleaning the eye wear.
3. Position emitter in viewing area
For hp visualization center sv6 systems that use monitors as display
devices, one emitter is usually sufficient for small groups. The
emitter is usually placed strategically on top of the user’s console
monitor(s) in the center of the user’s direction of gaze.
If more than one emitter is needed, they are usually positioned such
that the coverage angles (approximately 90 degrees horizontal arc,
40 degrees vertical arc) are sufficient for audience members to “see”
at least one infrared emitter when viewing a screen.
Always ensure that the sight line between an emitter and sensor on
the eye wear is unobstructed from all relevant angles of view.
4. Connect emitters to the Compositor
Recommended signal distribution from the graphics cards to
emitters is from a single point (the compositor controller card on the
master system) to the emitters. Emitters are serially connected
(daisy chained) with “T” BNC connectors using coaxial (BNC tipped)
cables between emitters.
Under normal circumstances, the master system’s compositor drives
one active stereo emitter. Greater numbers of emitters or longer
cable lengths may require signal amplification. Consult the stereo
equipment vendor for more information
