The Gefen Ethernet Over Coax

The Gefen TV Ethernet Over Coaxial Sender and Receiver units send RJ-45
Ethernet over RG-59 or RG-6 Coax cable at a distance of up to 300m/1000 feet.

Ideal for legacy installations where Coaxial cable is already permanently in place,
these devices breathe new life into remote network extensions where re-wiring is
not possible.

How It Works

Connect your existing Ethernet network cables to the Ethernet Over Coaxial
Sender unit, then plug in your Coaxial cable to the Coaxial jack on the Sender
unit. At the other end of your Coaxial cable run, attach the Ethernet Over Coax
Receiver unit and your network cables. Power-cycle your equipment. You will
now receive Ethernet network signals at the end of your cable run as if you had
cabled the run with Ethernet cables.

blue color on both units.

IMPORTANT: The Link LED must be emitting a sold blue color before
confi guration can continue. If this LED continues to fl ash red on both the sending
and receiving units, it is possible that they are not physically connected within the
current coaxial cable system. Please confi rm that both the sending and receiving
units are attached to the same coaxial cable system.

11

CONFIGURING THE GEFENTV ETHERNET OVER COAX

Once both the sending and receiving units are linked and powered, basic
confi guration can proceed. This section of the manual refers to the sending unit
as the LOCAL NODE, and the receiving unit as the REMOTE NODE.

NOTE: The following steps are for manual confi guration of the nodes for a
basic secure network. These steps are optional, as the nodes will function with
their default settings. However, for security and performance purposes, it is
recommended that the following steps be performed. Automatic confi guration is
also possible using the Automatic Security Confi guration feature on page 17 in
lieu of the procedure outlined in this section.

Ensure that both the local and remote nodes are powered and are properly 1.
linked.

Confi rm that the computer with the installed GefenTV Ethernet Over Coax 2.
software is connected to the local node.

Start the 3. Gefen TV Confi g Tool from this location:

Start Menu \ All Programs \ GefenTV Ethernet Over Coax \ Gefen TV Confi g Tool

The introduction screen should appear as the image below. Click on the next 4.
button to continue.

The program will begin to search for all connected nodes.5.

12

CONFIGURING THE GEFENTV ETHERNET OVER COAX

Once all possible nodes have been detected, the program will display all of 6.
these nodes as in the window below.

The local node that the computer is connected to will appear as the “ETH
connected node”. All remote nodes will be listed as “PLC connected nodes”.

NOTE: Both the local and remote nodes must use the same Net ID and
encryption passwords for proper operation. These will be confi gured in the next
step. However, it is important to confi gure the remote nodes fi rst. If the local node
is confi gured fi rst, all remote nodes will become inaccessible and will have to be
removed from their locations and physically connected to the computer, where
they can be confi gured to match the local node’s settings.

To begin confi guration, click on the mac address of the remote node (PLC 7.
connected node) and then click on the next button.

13

CONFIGURING THE GEFENTV ETHERNET OVER COAX

8.

The PLC node confi guration screen is separated into the following items:

NET ID

This is the name of the network. This name must be the same for both the local
and remote nodes for proper operation. The NET ID can be an ASCII string up to
20 characters long.

ENCRYPTION KEY

This is the password needed for network authentication by all nodes. If you wish
to set an encryption key, please set the NET ID fi rst. The password can be an
ASCII string up to 24 characters long.

ALIAS

This name is for easy identifi cation of the node. This can be an ASCII string of up
to 10 characters long. This fi eld is optional.

NEW PASSWORD (CONFIGURATION PASSWORD)

This is to set the confi guration password. If a new password is set here, the
confi guration tool will ask for it every time you access the node. The default
password is “paterna”. This fi eld is optional.

CONFIRM PASSWORD

The password entered into the new password listing above must also be entered
here. This is for confi rmation purposes.

Enter the Net ID, encryption key, and alias into the corresponding fi elds. Once
these fi elds are completed, click on the next button to continue.

14

CONFIGURING THE GEFENTV ETHERNET OVER COAX

Once the update is complete, a message will appear to indicate the update 9.
was successful. Click on the ok button to continue.

Once the update to the remote node is complete, you will be presented with 10.
a window that will give the option to either return to the main confi guration
window or continue with advanced confi guration.

For basic usage, it will not be necessary to continue to the advanced
confi guration. For advanced options, please see the ADVANCED
CONFIGURATION section on page 19. To continue with the basic confi guration,
click on the next button.

15

CONFIGURING THE GEFENTV ETHERNET OVER COAX

Once the confi guration for the remote node is complete, the local node will 11.
then have to be confi gured. Click on the local node which is labeled as the
“ETH connected node” and press next to continue.

Using the same Net ID and encryption key from the remote node, input 12.
the same information into the corresponding fi elds for the local node. The
Alias fi eld should be set to a different name as the remote node for easy
identifi cation.

Once the information has been input, click on the next button to continue. A
confi rmation window will appear once the update is complete. The same window
in step 10 will appear with the option to continue with the advanced confi guration.
It is not necessary to continue with the advanced confi guration for basic
operation. Click on the next button to return to the main confi guration window and
exit the confi guration tool by clicking on the exit button.

AUTOMATIC SECURITY CONFIGURATION FEATURE

To quickly setup the Gefen TV Ethernet Over Coaxial for secure use, the
Automatic Security Confi guration Mode (ASCM) can be activated on each node.
Follow the below steps to automatically setup a secure connection between
multiple nodes.

It is important to understand these concepts before proceeding with the
Automatic Security Confi guration.

Master Node (Fixed Access Point) - The Master node is the unit that all of •
the Slave nodes use to copy the Net ID and Encryption Key from. Because
all of the nodes on a network need to have the same Net ID and encryption
key to operate properly together, there needs to be a single Master node
that stores the information that all other Slave nodes will use to properly
confi gure themselves. A Master node is indicated by its Power LED glowing
a solid RED color. It is recommended to have only one Master node on the
coaxial network.

Slave Node (Normal) - A node in this mode will be indicated by its Power •
LED glowing a solid Blue color. Multiple Slave nodes can be on the same
coaxial network.

Automatic Security Confi guration Mode (ASCM) - This mode is initialized •
by pressing and holding the Security/Reset button on the front panel for
approximately 2 seconds. Once the node’s Power LED begins fl ashing RED,
release the button. This mode lasts for approximately 30 seconds and will
return to normal operation after this time period.

Both the Master and Slave nodes must be in ASCM for the automatic •
procedure to complete successfully.

When a Slave node initializes ASCM, it will fi rst attempt to fi nd a Master •
node in ASCM. If a Master node in ASCM is not found, it will assume the role
of the Master node. To avoid accidentally setting a Slave node as a Master
node, make sure that the Master node is in ASCM when activating a Slave’s
ASCM.

Any Slave node that assumes the role of a Master node will automatically •
have a random ASCII Net ID and Encryption Key generated.

Connect the computer with the installed Gefen TV Confi g Tool software to •
the node that you wish to initially set as the Master node.

If a node is connected to media server or router, it is recommended that this •
node be set as the Master node for increased performance.

Please refer to the next page for step by step instructions on how to activate the
Automatic Security Confi guration feature for the Gefen TV Ethernet Over Coax
nodes.

17

AUTOMATIC SECURITY CONFIGURATION

Connect the computer with the installed Gefen TV software to the node you 1.
wish to set as the Master node.

Press and hold the Security/Reset button on the node (ASCM), located on 2.
the front panel, for approximately 2 seconds. The Power LED should begin
to fl ash RED, then release the button.

After approximately 30 seconds, the Power LED should stop fl ashing and 3.
glow solid RED. This indicates that it is now a Master node. If this node was
a Slave node (normal node) before this process, it will now have a randomly
generated ASCII Net ID and Encryption Key set.

Open the Gefen TV Confi g Tool (page 12). There should be a random 4.
ASCII value as the Net ID. If you wish to use this Net ID for the other Slave
nodes, proceed to step 5. Otherwise, you can now set your own Net ID and
encryption password which will be applied to all of the Slave nodes in the
next step. To do this, click on the local “ETH connected node” MAC address
and press the next button. Change only the Net ID and encryption password
fi elds and click on the next button. Once the local node has been updated,
proceed to step 5.

For this step to complete successfully, both the Master and Slave nodes 5.
have to be in ASCM. To do this, press and hold the Security/Reset button on
the Master node for approximately 2 seconds. The Power LED should begin
fl ashing RED. Within 30 seconds, press and hold the Security/Reset button
on the Slave node(s) for 2 seconds to enter ASCM. The Slave node’s Power
LED should also begin to fl ash while it receives the Net ID and Encryption
Key information from the Master node. Once the Power LED on both the
Master and Slave nodes stop fl ashing and glow solid, the setup will be
complete. Check this by opening the Gefen TV Confi g Tool and seeing that
all nodes have the same Net ID.

NOTE: If the Slave nodes are located at a great distance from the Master node,
it is recommended that Step 5 be repeated for each Slave node separately.
The window that each device remains in ASCM is only 30 seconds, and it may
not be possible to put all Slave nodes in the ASCM within the time frame. It is
also possible to temporarily relocate the Slave nodes to a coaxial port closer
to the Master node for this confi guration process, and then move them to their
permanent location after this process is complete. If a Slave node is accidentally
set as a Master node, you can hard reset the node by pressing and holding the
Security/Reset button for approximately 10 seconds. This will revert the node to a
Slave node and reset all internal confi gurations to factory settings.

18

ADVANCED CONFIGURATION

There are optional advanced settings that can be confi gured for each node. The
advanced menu can be accessed directly through the main confi guration page.
Click on the MAC address of the node you wish to confi gure and click on the
advanced button to the left of the node listing.

GENERAL

Hardware Reset

This will reboot the node. Settings made in this menu will be applied once the
