AVAS-212 is an IP network-based system to distribute and switch video,
audio, and control signals (like USB for mouse and keyboard and
RS232). The system has been designed to deliver video with high
quality (including uncompressed, lossless distribution) and low latency
for optimal hand-eye coordination in critical applications.

andsafetyrisksapplicabletothe integrated system.
The AVAS-212 system and its components have CE approval and
comply with IEC60601-1-2. Installers, system integrators, and OEMs
have to mitigate system and application specific risks.
For critical systems, installers and system integrators are advised to
consider arranging additional risk control measures, like external
back-up system(s).
3.1 Application Notes
When integrating a product like AVAS-212 into safety critical
systems, the risks associated withfailuresinthe AVAS-212network
havetobeconsidered. Although the systemintegratorsandOEMsare
responsibleforoverallsystemsafety(basedontheir expertiseofthe
applicationdomainandoftheoverallsystemarchitecture),ananalysis
has been performed to study the safety impact of AVAS-212 in
safety critical applications.Thefollowingapplicationnotesarebasedon
theoutcomeofthisanalysis:
When AVAS-212 is used in safety critical applications, address the risks associated with
failure of video and audio delivery due to, for instance, failures of network equipment in your risk
analysis. In these cases, consider applying fail-safe, redundant video or audio connections in parallel
to the AVAS-212 video network as a risk control measure.
AVAS-212 can transfer unprocessed video without compression.
Scaling and conversions will be applied when the video input properties (resolution, frame rate or
color scale) are not equal to the requested video output properties.
For applications in which this type of processing can result in hazardous situations due to, for instance,
image artefacts or loss of information, using the DirectDisplay mode or carefully matching video input
and video output properties is recommended to assure video transfer without any processing.
Seethe AVAS-212 User API fordetailsofsettingvideoinput/output propertiesandfor
instructions to enable the DirectDisplaymode.
To avoid hazardous situations caused by mixing up video sources, adding clear visual markers to the
video input streams is recommended.

3.2 Medical Installations
For integration into an IEC60601-1-compliant Medical Electrical System,
the AVAS-212 NDcoders have been tested and are compliant with IEC
60601-1-2:2007 in combination with the power supply delivered. This
power supply has a low leakage current (<50uA@264VAC) and is
double isolated (MOOP&MOPP).
The system integrators (RESPONSIBLE ORGANIZATIONS) are reminded
that the assembly of ME SYSTEMS and modifications during the
actual service life must be checked for compliance with the
requirements of IEC 60601-1. The standard gives more information
about the general safety requirements for ME systems.

4. SYSTEM COMPONENTS
The AVAS-212 system is structured as shown in Figure 1. Video
sources and video destinations (typically displays) are connected to
AVAS-212 interface modules. These interface modules are called
NDcoders (because they provide both encoding and Decoding
functionality).
TheNDcodersareconnectedtoa10gigabitEthernetswitch.Video,and
audio aredistributed amongtheNDcodersoverthisnetwork.Software
runningonaPC thatisconnectedtothenetwork isusedtomanage the
channels between theinputand output ports of the NDcoders. This
software, called the AVAS-212 Server , provides an API tocontrolthe

Before cleaning the NDcoders, first disconnect the power supply from the
NDcoder, and then disconnect all other cables.
Use only a moist, soft, and lint-free cloth. Avoid abrasive cloths, towels, paper towels, and similar
items that might cause damage to the aluminum housing. Ensure that no moisture enters any
opening and only use mild cleaning agents.
The enclosure of AVAS-212 is made of aluminum that can help heat dissipation, since the device does
not have cooling fans. Please provide regular maintenance to remove any dirt or dust on the enclosure
that can reduce the cooling capacity of the enclosure.

The AVAS-212 Server Software provides the AVAS-212 User API . The
AVAS-212 User API is the application programming interface that is
available for users of the AVAS-212 system. The AVAS-212 User API
provides functions to control the video, audio, and control streams
between the NDcoders in the system. You can create and configure
channels between NDcoder ports and retrieve status information,
configuration information, and statistics for system diagnosis.

If the AVAS-212 Server were to fail, the whole system will continue to
function in the state it was in when the failure happened. During the
absence of AVAS-212 Server functionality, the video and audio
streams will continue without interruption . It is not possible to change
the video, and audio channels when the AVAS-212 Server is not
operational. All functionality will resume automatically as soon as the
AVAS-212 Server functionality has been re-established.
4.3 Network Switch
AVAS-212 uses a 10 gigabit Ethernet network to transfer data
between the NDcoders. AVAS-212 is compatible with a wide range of
commercially available network switches. When selecting a switch,
please make sure that it complies with the following requirements:
 10 gigabit SFP+connectors;
 full bi-directional switching bandwidth (for all ports);
 Layer 3 multicast;
 IGMP snooping;
 IGMP querying;
 Jumbo frames.
In addition, please ensure that a DHCP server has been installed
in the AVAS-212 network.

CAUTION!
When a firmware version is installed on an NDcoder that is not compatible with the AVAS-212 hardware
version, the NDcoder will not start up. Installing an incorrect firmware version may damage the hardware of
the NDcoder. After installing an incorrect version, installing a new version (to correct the installation) may
no longer be possible. In these situations the NDcoders have to be returned for repair.
Information about software and hardware compatibility and about updating the NDcoder firmware can be
found in the AVAS-212 – Software and Firmware Manual.
Ensure that the firmware installed in the AVAS-212 NDcoders is compatible with the installed version of
the AVAS-212 Server Software. When the NDcoder firmware is incompatible with the running AVAS-212
Server Software, the NDcoder might not be detected by the AVAS-212 Server Software. In this case the
NDcoder will not function correctly.
Information about NDcoder and AVAS-212 Server compatibility and about updating the AVAS-212
ServerSoftwareortheNDcoderfirmwarecanbefoundinthe AVAS-212 – Software and Firmware
Manual.
Mixing AVAS-212 NDcoder firmware packages from different releases will not result in optimal system
performance. Please use NDcoder firmware versions from one distribution in all NDcoders in your
system, in combination with a compatible version of the AVAS-212 Server Software.
