SECTION 1. GENERAL INFORMATION
1.1 INTRODUCTION
The KNOX RSIII AUDIO/VIDEO ROUTING SWITCHER is a family of devices, which accepts
up to sixteen video sources and sixteen stereo audio sources. The RSIII connects any one of the
sixteen inputs, to one or more of the sixteen outputs, depending on model. The video signals may
be switched independently or with the audio signals.
The RSIII family of switches consists of five basic models; Composite, Y/C, RGB/YPbPr and
RGBHV any of which can contain balanced, unbalanced or no audio. Optional features include
volume and tone control for the audio as well as capability to output the audio and video signals
over CAT 5/6 cable.
1.2 TECHNICAL DESCRIPTION
The RSIII uses a single chip microprocessor with flash memory to control a set of monolithic
digital latching crosspoint decoders. Cross-point information is collected by the microprocessor
from the front panel controller, the RS232/RS422 and Ethernet inputs on the rear panel. Audio
and video may be routed together or separately. The audio volume, tone, and balance may be
adjusted if the VT option is installed.
