Class B Digital Device. This equipment has been tested and found to comply with
the limits for a Class B computing device pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful
interference in a residential installation. However, there is no guarantee that
interference will not occur in a particular installation. This equipment generates,
uses, and can radiate radio frequency energy, and, if not installed and used in
accordance with the instructions, may cause harmful interference to radio
communications. If this equipment does cause harmful interference to radio or
telephone reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the
interference by one of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
• Consult an experienced radio/TV technician for help.
CAUTION: Changes or modifications not expressly approved by the party
responsible for compliance could void the user’s authority to operate
the equipment.
To meet FCC requirements, shielded cables and power cords are required to con-
nect this device to a personal computer or other Class B certified device.
This digital apparatus does not exceed the Class B limits for radio noise emission
from digital apparatus set out in the Radio Interference Regulation of Industry
Canada.
Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les
limites applicables aux appareils numériques de classe B prescrites dans le
Règlement sur le brouillage radioélectrique publié par Industrie Canada.

Chapter 2: Overview
2. Overview
2.1 Introduction
The 4K Modular Matrix Switcher 8 x 8 is a high-performance video and audio modular
matrix switcher. It supports different video signals with cross switching. Every video or
audio signal is transmitted and switched independently to decrease signal attenuation.
AVS800 supports various changeable cards including HDMI, DVI, VGA, SDI, and
HDBaseT etc, and all the cards support hot plug-and-play. Users can choose to insert
different signal cards for different applications. AVS800 has a power fail memory
function and audio can break away from or follow the video to the switch. It has an
RS-232 port for serial control and an optional IP port for TCP/IP control. It can be easily
controlled by third-party devices.
With its flexible design, AVS800 can be used for different projects and is all-in-one
solution. Applications include multimedia conference rooms, control rooms,
broadcasting rooms, shopping centers, etc. The AVS800 handles all the audiovisual
management, including the switching, driving, scaling, etc.
2.2 Features
• Modular chassis with configurable I/O slots..
• Various I/O cards includes HDMI, HDBaseT, DVI, and VGA cards (compatible with
YUV, YC, and CVBS) to configure any matrix.
• True cross-point switching, any input to any output, regardless of signal format.
• Supports HDMI1.4a and 3D.
• Integrated HDBaseT technology.
• Controllable via button, RS-232, and optional TCP/IP, also compatible with third-party
control.
• HDCP compliant.
• LCD display.

2.5.2 Changeable Cards
The AVS800 supports expansion via various changeable input/output cards that use
different signals including DVI, HDMI, VGA, twisted-pair, etc.
AVS-4I-DVI and AVS-4O-DVI
DVI signal cards. (See the specifications in Chapter 1.) These cards are compatible with
HDMI1.3 and HDCP, but do not support analog signals. The cards use embedded EDID
management technology and support DDC.
AVS-4I-DVI: input card with maximum four input signals. The input signal can pass to
an output device through AVS-4O-DVI, or pass through other kinds of output cards.
