A: SETUP PROCEDURE The basic connections clearly illustrated on the printed Set-up card together with more detailed documentation on CD enabled the Polycom® VSX™ 6000 to be installed and set-up with ease. Initial installation involved: • Positioning the combined CODEC/camera unit on top of the monitor. • Connecting the CODEC to the video monitor using the video and audio leads supplied. • Plugging the microphone into the CODEC. • Establishing the IP network connection via a si

B: HARDWARE DESCRIPTION General The Polycom® VSX™ 6000 is a compact entry level portable system for IP communication up to 768kbit/s. Several optional features are available: • Dual Monitor hardware. • Up to two additional desk microphones. • Integration with the VTX1000™ conference phone. Images from a PC/laptop can be introduced into a conference by two methods: 1. A hardware option, Visual Concert VSX enables a PC/laptop to be directly connected (hard wired) into the CO

CODEC and then fed into a conference. This unit also provides an XGA data projector output and a three port network hub. The VSX unit connects to the desk pod microphones via a ‘daisy chain’. When conferencing with other Polycom units supporting People + Content™ any XGA data source connected to the Visual Concert™ VSX unit can be transmitted to the remote site together with the selected video source. To route this XGA signal to the remote site either the Graphics button on the remote con
