The lightning flash with arrowhead symbol, within an
equilateral triangle, is intended to alert the user to the
presence of uninsulated “dangerous voltage” within the
product’s enclosure that may be of sufficient magnitude
to constitute a risk of electric shock to persons.

The exclamation point, within an equilateral triangle, is
intended to alert the user to the presence of important
operating and maintenance (servicing) instructions in the
literature accompanying the appliance.

For U.S.A.

NOTE: This equipment has been tested and found to comply with the limits for a Class A
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 in

Caution — STANDBY/ON switch!
Disconnect the mains plug to shut the power off completely. The STANDBY/ON switch in any
position does not disconnect the mains line. The power cannot be remote controlled.

Attention — Commutateur STANDBY/ON!
Déconnecter la fiche de secteur pour couper complètement le courant. Le commutateur
STANDBY/ON ne coupe jamais complètement la ligne de secteur, quelle que soit sa position. Le
courant ne peut être télécommandé.

RoHS – Restriction of Hazardous Substances

The RoHS Directive, enacted by the European Union (EU), restricts the use of six
hazardous substances (lead, mercury, cadmium, hexavalent chromium, polybrominated
biphenyls or polybrominated diphenyl ethers) within electrical and electronic equipment.
The goal, consistent with other international regulations, is to contribute to human health
and the environment by restricting the use of these hazardous substances in new
equipment. Manufacturers of electronics products outside Europe must abide by this
legislation if the equipment they produce is ultimately imported in a EU member state.
This equipment complies with the RoHS directive 2002/95/EC.

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.
