In order to access the web-based configuration pages, it is necessary to know the
adapter’s IP address and for your computer to be connected to the CableLAN
adapter (as described in section 2.5). Corinex adapters come with a default IP
Open a web browser (Microsoft Internet Explorer v6.0, Mozilla v1.7.2 and Mozilla
Firefox v1.0 have been verified for use with these products.), and type the IP address
in the address bar – the URL should be unless you have already
changed it to something else.
Changing the default IP address is required, so that two or more devices can be on
the same network. The IP address is a device’s unique identifier on a network, so
the adapters would not be able to tell each other apart if they had the same identity,
just as a postman wouldn’t know which house to deliver to, if two neighbors in a
large city had the same street number. Follow the steps below to configure a new
IP address for each adapter:
1. In your computer’s network settings, enter an address in the range 10.10.
X.X (e.g. and set the netmask to This is necessary in
order to be compatible with the adapter’s default settings. For details on how
to set up an IP address on your computer, please see chapter 5.

3.4 Change Configuration Page
3.4.1 Overview
The configuration pages allow you to change the settings on the CableLAN adapter.
Any parameters changed here will be stored in the CableLAN adapter‘s permanent
memory, and at the next startup, will be activated automatically. Any changes will take
effect immediately after startup, with the exception of the Network Configuration
settings (these require a restart of the CableLAN adapter).
The configuration is divided into two sections: “Basic settings” and “Advanced
Notes :
• A different IP must be set for each adapter on the network. The adapter’s
IP does not need to be in the same range as the PC, except when trying to
change the adapter’s settings on the configuration page (10.10.X.X and netmask for an adapter with the default factory settings).
• The adapter’s netmask can also be changed, for example to a type C
( if necessary. This is a more advanced option, which you may
ignore if you’re not familiar with it.
Corinex AV200 CableLAN Adapter
Adapter Configuration
• If the CableLAN adapter is to be accessed through a router (e.g., in a large office
network), the gateway IP needs to be configured. Otherwise, it can be ignored.
Basic Settings
Most of the time, the only thing that needs to be changed is the Network Identifier
and the Encryption, in order to avoid interfering with other networks and protect
your information. Most people will not need to enter the Advanced settings section.
The AV200 CableLAN network is totally secure with these basic settings.
The AV200 technology supports multiple networks on a single circuit. The networks
are differentiated by Network Identifiers, which can be set in this section. The
Network Identifier is a string of characters (Network Identifier field) which simply
acts as a name for the network. This Network ID must be identical for all adapters
on a network. Adapters with different Network IDs will not be able to communicate
with each other.
The Network Identifier string can have up to 20 ASCII characters (lettters and
numbers). Quote and double-quote characters are not supported. Extended ASCII
characters are not recommended.

On the other hand, if HEX mode is
selected, the Encryption Key string can
have up to 42 hexadecimal digits (for
example 34AE4F54B38D). This HEX
method is more secure than ASCII.
3.4.3 Advanced Configuration
The advanced configuration section is divided into several subsections, which are
described here. MAC Configuration
The following parameters relate to the physical network setup, or topology. The
current firmware version (Spirit 2.0.21 at the time of this publication) supports only
one topology: In-Home AV. In this In-Home AV topology, two different adapter
types can be configured, setting an adapter to function as either an Automatic
EP/AP (End Point or Access Point, depending on the other adapters in the network)
or a Fixed AP (assigned Access Point). Section 4 (In-Home AV Network Topology)
contains more information about the available network topologies.
Corinex AV200 CableLAN Adapter
Adapter Configuration
If you want to configure the CableLAN adapter to function as an automatic EP/AP,
please select “EP” from the list. If you want the adapter to behave as a Master,
select “Fixed AP” from the list. After selecting one, click “OK” to confirm your
Note: Fixed AP is available only when a Network ID is set on the adapter
(please read below for details on Network Identifiers).
The AV200 technology supports multiple networks on a single circuit. The networks
are differentiated by Network Identifiers, which can be set in this section. The
Network Identifier is a string of characters (Network Identifier field) which simply
acts as a name for the network. This Network ID must be identical for all adapters
on a network. Adapters with different Network IDs will not be able to communicate
with each other.
Note: Please refer to section 4.2 for more information about the network
types and their Network Identifiers.
If the Network Identifier field is left blank, the default, publicly available network is
configured, and the adapter can communicate with all other adapters with empty
Network Identifier fields. When you enter a Network ID, a private network is

The following picture shows an example of two AV200 networks with different
Network Identifiers:
Communication between adapters (called modems in this picture) is encrypted with
a Triple-DES algorithm. The Encryption Key can be set to any string of letters and
numbers (Encryption Key field, ASCII or HEX). Saving an empty string (leaving it
blank) disables the encryption. After selecting ASCII or HEX and then entering a
password, click “OK” to confirm your choice.
Note: The encryption will be enabled only if a non-empty Network Identifier
is set.
Note: If ASCII is selected, the Encryption Key string can have up to 24
non-standard ASCII characters. Quote and double-quote characters are not
supported. Extended ASCII characters are not supported.
On the other hand, if HEX mode is selected, the Encryption Key string can
have up to 42 hexadecimal digits (for example 34AE4F54B38D). HEX strings
generate stronger keys.
Corinex AV200 CableLAN Adapter
Adapter Configuration Network Configuration
Your Corinex AV200 CableLAN Adapter can be configured to use either DHCP
(automatic IP address assignment), or a fixed IP.
The following parameters are used by the fixed IP configuration. In order for the
CableLAN adapter to correctly communicate with other devices on the network, it
is necessary to define a valid IP address, as well as a proper subnet mask and gateway
address. These parameters will be saved in the CableLAN adapter’s memory and
activated at the next restart.
After changing any of these parameters, click “OK” to save your changes.
Note: Any change in the Network Settings requires a restart of the CableLAN
adapter to take effect.
Note: If you forget the IP address of the device, please recover it with the
utility “getIP,” which is located on the Documentation CD, or download it
from the Corinex website at
PHY Configuration
By default, the adapters transmit over a frequency range anywhere from 2 to 32
MHz, and when an access network is detected, the adapters transmit over a range
from 13.3 to 33.3 MHz, in order to operate without interfering with each other.
This mode change is done automatically and cannot be configured by the user. It is
only possible to enable or disable this „notches“ function. The notches pre-defined
in the adapter correspond to the IARU (International Amateur Radio Union) band
plan for each world region. If the adapter is running in an environment where it can
cause interference to a HAM radio receiver, it is recommended to enable notches,
in order to block the CableLAN signal from the frequency bands used by radio
Corinex AV200 CableLAN Adapter
Adapter Configuration
Note: It is strongly advised to turn on the notching function.
Power Control is an automatic transmission power control which prevents different
networks from overpowering each other.
Power Control is turned on only when other networks are detected in the channel.
If the transmission strength reaches the isolation point between networks, the
transmission power is limited from overpowering the other network. If the isolation
point is not reached, the adapters continue transmitting as normal.
Multicast Configuration
In order to optimize multicast traffic (video streams, etc.) between AV200 CableLAN
adapters, you can specify which adapters should receive the video. Other adapters
will then not be able to receive the multicast communication, and therefore the
bandwidth will be used only for transmission to the intended recipients, making your
broadcast, and your entire network, more efficient.
This form shows the list of multicast bindings, where the IP addresses of adapters
are assigned to a unicast (video source) MAC address. This list can be saved to
memory on the CableLAN adapter (Save in NVRAM). Bindings can be removed by
checking their “Remove” checkboxes and clicking “OK”. Add a new binding to the
list by entering the multicast IP address in decimal format (ddd.ddd.ddd.ddd), and
the unicast (source) MAC address, in hexadecimal format (XXXXXXXXXXXX), in
the appropriate fields and clicking “OK.”
The new IGMP Aware Multicast Syndication feature can be enabled via this form.
This feature is only available on private networks (those with a valid Network
Identifier) and End Points (EP).
Corinex AV200 CableLAN Adapter
Adapter Configuration
VLAN Configuration
When AV200 CableLAN Adapters are used for ADSL extension, it is important
for the operator to be able to distinguish the type of traffic that each adapter is
generating. This is usually done by means of VLAN tagging. The AV200 technology
includes the ability to tag all traffic that enters the CableLAN network through each
adapter’s Ethernet interface. It is only tagging - there is no VLAN filtering on an
AV200 CableLAN network.
The parameters for VLAN configuration can be set in the form displayed below.
First, the Spirit VLAN can be enabled or disabled (Spirit VLAN Configuration
checkbox). If enabled, the VLAN tag (Spirit VLAN Tag field) and priority (Spirit
VLAN Priority field) can then also be configured.
Priority Configuration
It is possible to configure the Activity LED (in the middle of the front panel). The
LED shows the quality of the network connection to other AV200 devices. There
are two configurable speed markers. The adapter simply reads the network speed
and changes the blink rate of the Act LED according to these markers. The default
values are 25 Mbps and 75 Mbps.
IMPORTANT NOTE: This advanced LED functionality is available only when
a Fixed AP (described in section is present on the CableLAN network.
In order to function correctly, the Fixed AP must be connected to your internet
connection or to the first device on your network (i.e. modem or router). If
there is no Fixed AP on the network, the LEDs may not behave as described

Corinex AV200 CableLAN Adapter
Adapter Configuration
Several options are available in this form. The first, and easiest to understand and
use, is the Default Priority value. Output traffic generated by adapters with higher
default priority will have preference in the network. The rest of the parameters let
you configure two Class of Service criteria (Criterion 1 and Criterion 2 checkboxes).
If you select None, 8021p or TOS, custom parameters are hidden, leaving a predefined setting in place.
If you select Custom on the other hand, custom parameters are shown as below
and can then be configured.
When several traffic flows are sharing the same network, it is sometimes necessary
to establish several levels of priority in order to guarantee that bandwidth-sensitive
applications like video and telephony function smoothly under network congestion.
The traffic classifier is a packet inspector that is able to recognize several patterns
in an Ethernet frame, and assign a different priority to each of them. To ensure
that the classification is done correctly, there is a trigger mechanism prior to the
actual classification. The trigger mechanism is also based on pattern recognition of
a given location in each Ethernet packet. The following picture depicts the packet
classification mechanism:
There is one offset, and one bitmask and pattern for the trigger condition. The trigger condition is used to make sure that the Ethernet frame contains, for example,
an IP frame. To check this condition, the offset must be set to 16 and the bitmask
to 0xFFFF. If the resulting pattern is 0x0800, then the Ethernet frame contains an IP
packet and the classification can be made to a known field.
There is another offset and bitmask for the classification condition. The resulting
value is compared with a set of patterns. If the value matches a given pattern, the
packet will be classified with the specified priority. If the value does not match any
Corinex AV200 CableLAN Adapter
Adapter Configuration
of the patterns, it will get a default priority.
There is a set of pre-defined criteria which classifies traffic based on the 802.1p field
of the Ethernet packet or the TOS field of the IP packet.
Security Configuration
The configuration page allows you to change the password. Type your new password and confirm by typing it in a second time. If both fields are left empty, the
password will be disabled (the message ‘No password installed’ will be shown).
You can turn the password protection back on at any time by simply entering a password, as described above..
Factory reset will restore the adapter‘s default settings. The system will ask for
the password, which is “betera“. Then click OK. The adapter will restart with the
following configuration:
IP address =
Configuration interface password = paterna
Factory reset password = betera
Device type is Automatic EP/AP
Network Identifier is blank
No encryption and no VLAN settings
3.4.9 Hardware Reset
Clicking on this button will restart your adapter. The configuration will remain the
same, and any changes made in the Network Configuration section will be applied.
This means that if you’ve changed the IP address, the adapter will restart with the
new IP address.

3.4.12 Configuring Video Applications
On a network where real-time traffic must co-exist with massive data transfers, the
service classifier must be used to prioritize the more sensitive traffic above the other
types of traffic.
As an example, consider the network shown below :

Adapter Configuration
The adapter connected to the ADSL adapter is the access point. Data and video
are delivered through ADSL. The access point must prioritize the video higher than
other data, to avoid a jittery image whenever there is a heavy data download.
First of all, the Criterion field must be set to Custom, in order to create custom
rules for traffic classification.
To prioritize UDP traffic, first the Ethernet packets containing IP packets must be
detected. This requires detecting the pattern 0x0800 at offset 16. Because the field
to inspect is two bytes, the bitmask must also cover the same space. Therefore,
0xFFFF is used as the bitmask. These values are introduced in the fields Custom
Criterion Offset, Custom Criterion Pattern and Custom Criterion Bitmask.
Once the trigger condition is entered, the classification rules must be specified.
Only the fields that are actually changed will take effect. The rest will be ignored.
IP packets have a one-byte field at offset 27 that indicates the Protocol Type.
UDP protocol is pattern 0x11. Because the field to inspect is only one byte, the
bitmask is also one byte. The values are entered in the first available rule (1) as Class
Pattern 1 and Class Priority 1.
The rest of the traffic (FTP, web browsing, etc.) will receive default priority 2. On the
other side of the network, the adapter connected to the computer will also classify
outgoing data traffic with default priority 2 because no rule has been programmed.
Note: While the offset value is assumed to be decimal, the patterns and the
bitmasks are in hexadecimal format by default.
3.5 Firmware Update Page
This page appears when a firmware update is requested from the Change
Configuration page, and it shows the status of the current firmware update.
The Firmware Update page is reloaded automatically every 30 seconds. When
the status line shows Ready: finished correctly, the CableLAN adapter can be
restarted, and the new firmware will be activated.
If the update process fails, an error message will be shown. In this situation, the
CableLAN adapter can be reset without any risk, but the old firmware will still be
present on the adapter.

Video Network Setups
4 Video Network Setups
4.1 Introduction
An In-Home AV network is made up of an access point (AP) adapter and several end
points (EPs). In-Home AV networks can have only one AP. However, several InHome AV networks can be created in the same space, each of them with its own AP,
because each network is isolated by a unique network identifier. An adapter can be
configured as a Fixed AP (i.e. it always will be an AP) or an automatic EP/AP. When
set to automatic, the In-Home AV protocol decides which adapter will function as
an AP. This means that if no Access Point (AP) has been defined, an End Point (EP)
will be automatically set to function as an AP.
Note: It is recommended to configure a Fixed AP. This provides increased
stability for future reconfigurations and in multi-network environments.
Note: It is not necessary to have full connectivity between all the adapters on
a network. The network topology will be configured automatically, allowing
for the use of repeaters if the connectivity between two adapters fails.
The necessary steps for setting up a basic In-Home AV network are, for each
adapter, as follows:
Set its IP address. It should be a unique IP address (e.g. private address like
10.10.1.<pick a number>).
Select the spectral configuration (notches enabled or disabled).
Set the Network Identifier. It should be the same value for all adapters on the
Configure the Encryption Key. It should also be the same value for all adapters
on the network.
It is not necessary to configure the In-Home AV MAC, since there is only one
available network topology in the current firmware version. To configure a Fixed
AP is optional.
4.2 Network Scenarios
This section contains a few network scenarios, explaining the application and
necessary configuration.
There are two types of In-Home AV network.
Corinex AV200 CableLAN Adapter
Video Network Setups
• Public Network - This is the default configuration of an In-Home network. If
you do not want to change the settings on your network, the network
configuration protocol will configure all the adapters automatically. By default,
all adapters are EPs and have a public (empty) network ID. If the protocol
does not detect an AP in the channel, it will change an EP to act as an AP. All
EPs will connect directly to the automatic AP if they can, or to an EP that will
act as a repeater. Then the network will be established.
• Private Network - To configure a private network (to ensure data privacy),
a network ID must be assigned to all adapters on the network using the
configuration tool. It is recommended to configure a fixed AP (for
example the adapter with the video server or Internet access). If the fixed AP is
turned off or is not defined, the network configuration protocol
will select an EP to change to function as an AP (automatic), in order to
configure the network.
4.2.1 Single-Network Scenarios
The following two sections show examples of a single In-Home AV network.
29 Local Area Network using two AV200 CableLAN Adapters
The picture below shows a simple CableLAN network where two adapters are
used to make a local area connection available in all outlets of the house. This is the
simplest case, where no QoS (Quality of Service) configuration is required.

This picture shows a more advanced CableLAN network with three Corinex AV200
CableLAN Adapters. This is a common network configuration, where Internet access
and digital video are delivered through the same ADSL line. This configuration
requires some QoS (Quality of Service) settings to guarantee video quality when the
network is carrying large amounts of data from the Internet connection.

Note: Either of these two basic scenarios can be enlarged, adding more adapters,
computers and set-top-boxes.
4.2.2 Multi-Network Scenarios
A multi-network scenario occurs whenever there are two or more adapters from
different networks (different network IDs) on the same circuit. In this case, a
coexistence mechanism is included, which allows a secure form of communication
without interference from adapters from other networks.
Corinex AV200 CableLAN Adapter
Video Network Setups
In multi-network scenarios, such as the one depicted in the picture above, there is a
new entity, called the QoS controller. The QoS controller’s role is to assign channel
access to the different networks. The QoS controller acts at the same time as the
AP of one of the networks. In the presence of several networks, the coexistence
protocol automatically selects one of the APs as the QoS controller. Two Networks on Different Circuits
If two In-Home AV networks are configured, with no direct visibility between any of
the adapters belonging to different networks, then these two networks will behave
as two independent networks. Both APs will act as QoS controllers. Two Networks on the Same Circuit
Different networks are defined by different network IDs.
If two In-Home AV networks are configured as public networks, the coexistence
protocol will act as if there were only one network. The network ID is transmitted
by every adapter to communicate the existence of its network. If an adapter with
network ID A receives network ID B, then it knows that there are at least two
networks sharing the channel.
For example, one In-Home AV network is configured and running. A second
network is configured and becomes active. Then the second network will notify
the first network of its existence in some specified access slots, and both networks
will automatically be reconfigured and will share the channel. If both networks are
configured at the same time, the QoS controller will be selected from all available

5.2 Improving Network Performance
The latency (delay) of a CableLAN network is higher than that of an Ethernet
network. Most operating systems have a default setting of the network latency
based on Ethernet figures. To obtain the maximum performance using TCP traffic
(FTP download, for example) the operating system has to be tuned to the new
network conditions.
For improving the network performance, we provide scripts for Windows and
Linux operating systems. The scripts can be found on the enclosed CD, in the folder
scripts. The scripts will set the TCP window size to 512 kB.
With a Windows PC, simply double-click on the file tcpwin.reg, provided on the
documentation CD in the “scripts“ folder. You can also run the script using the
autorun feature on the CD.
tcpwin.reg for use with Windows operating systems

With a Linux PC running kernel 2.4 or higher, open the console and execute the
command ./ 512 logged in as root. for use with Linux operating systems
After applying the script, please restart the system. This applies to both Windows
and Linux.
5.3 Checking Network Performance
On the Main page, under the heading Available CableLAN Connections, is a
list of the MAC addresses of all of the neighboring adapters that have a connection
with that adapter. The list also indicates the physical throughput (actual data rate),
in terms of both transmission and reception, that the adapter is achieving with each
adapter on the network.
5.4 Using Coaxial Filters
A coax filter is a high-pass filter which allows only the TV signal through. This filter
blocks the AV200 CableLAN signal (2-34 MHz).
Corinex AV200 CableLAN Adapter
Network Configuration
When to use this filter:
• When you want to isolate your AV200 CableLAN network from the rest
of the coaxial infrastructure, either because you don’t want the CableLAN
signal from your network to go out and disrupt other adapters, or because
you want to isolate this network from the noise, or other traffic, in the rest of
the cable network.

The Corinex AV200 CableLAN Adapter has been designed to be a reliable and easy-touse network connection device. Please refer to the list below to aid in troubleshooting
or visit and go to the appropriate section for information
on your product. There you will find news, manuals and software updates, as well as
frequently asked questions (FAQ).
The POWER LED is off.
1. Make sure the CableLAN adapter is properly plugged directly into the electrical
outlet, and that the outlet has power.
2. Try another outlet.
The CableLAN Act LED is off.
1. Make sure there is no analogue TV amplifier or too many T-splitters between
the AV200 CableLAN adapters which should communicate.
2. Try to connect two AV200 CableLAN adapters with a short coaxial cable for
a short test to check the connectivity.
The Ethernet LED is off.
1. Make sure the adapter is connected with an Ethernet enabled device with an
RJ-45 cable and both devices are powered.
To avoid personal injury and damage to the system:
1. The principal method to disconnect the device completely from the electrical
power network (mains) is to unplug the power cord from the wall socket.
2. Never install the unit in wet areas or next to radiators/heaters.
3. Never use the unit outside.
4. Unplug the unit during severe storms.
5. Never open the equipment enclosure.
To verify that your equipment is connected and working correctly, use the standard
Ping utility. In Windows, click on menu Start -> Run, then type the command
ping IPADDRESS -t, where IPADDRESS is the IP address of the computer to
which the CableLAN adapter is connected, e.g. ping -t (this process
can be interrupted by pressing CTRL+C).
1. Ping the IP address of the computer to which the CableLAN adapter
is connected. If this fails, there is a problem with the Ethernet
network card or with the TCP/IP protocol.
2. Repeat the same process with the other computers on your AV200 CableLAN

3. If all the computers can ping themselves, try pinging another computer on
your AV200 CableLAN network. If this fails, then there is a problem with the
connection across your AV200 CableLAN network or with the configuration
of the CableLAN adapters. Check the connection to the
outlet, or try a different outlet. Verify the configuration of your
adapters, especially the network number, as only adapters
on the same network can see each other. Please see chapter 3 for details on
