Wodaplug EOC Slave, 4 x 10 / 100 M



(new model, chip QCA7411L)

This is the data transfer network adapters Ethernet coaxial cables, based on the technology, which offers great HomePlugAV range (700-1500 m), high speed (up to 600 MB/physical speed with speed on the MAC layer of more than 300 MB/s), resistance to interference and during the big decline.

Simply apply the device to the involvement of the building to the Internet after a common coaxial divorce. Allows you to communicate the many units after a single coaxial lead signálovou speeds up to 600Mbps. Site management is done through the Master unit, each slave do not have their IP addresses.

EOC (Ethernet over COAX cable) means divorce Ethernet over coax network, on an existing coaxial cable transmission offers the current divorce TV/SAT signal along with the data signal. For the application of the computer network of EOC contains the Head End unit called the Master, which connects the signal to the TV with the data network Ethernet to coaxial mixed signal and an end unit called a Slave, a Master may serve up to 256 of the Slave units, the network structure can be a star or tree. The unit provides data broadcasting EoC master Ethernet over coaxial wiring, it is suitable for a wide range of deployment in the implementation of network applications, which use the existing coaxial wiring, how home installation (in-home) and commercial (offices, apartment houses, hotels, factories). You do not need to install any new cables. This device will allow you to realize the high-speed network for the transmission of video, voice and data.

The structure of the network is the starfish and the tree with one central unit and with several (up to 256) Slave units, which can be isolated from each other (slave izolation).
The Master unit is connected to a switch or router, and exposes the data to all Slave units. The unit also contains a central NMS/network management system/, which is the old configuration and diagnostics of the whole network and is accessible through the remote management WEB, Telnet, IP, SNMP, CLI …

In the download section you can find the Master + Slave EOC instructions GB description principle and installation, then datasheety to the Master and Slave units and further instructions to the NMS (Web configuration).

The Slave unit to the 4 Ethernet ports for the attached end device. Slave drives are configured and monitored via the NMS in the drive Master.

The slave unit is determined by the EoC for end users and works with the EoC master unit to establish the connection and transmission of Ethernet over coaxial divorce. Of mixed signal again converts the data to the output signal to Ethernet and the TV output TV.

Supported are all the necessary network features such as QoS, VLAN, IGMP, bandwidth management, and more. Appropriate, therefore, to the realization of any network (even for the transmission of voice, video, and IPTV) using existing coaxial cables.

The new hub, are also necessary to connect the coax network integrated in the device, thus has two connectors for coax cable (input and output).

Depending on the installed unit can connect CATV drawers directly between the TV and the receiver port socket. In the event that the attenuation of the radio interference suppression filter in older types of Sockets does not allow such direct deployment is necessary to replace the socket. Replaced by a so-called “. Double socket.

The device is intended for the MDU System (Multi-Entitled) that provides network administrators the ability to control bandwidth. At the same time, this system allows the location of the user more (than it is in the case of Ad-Hoc or Peer-to-peer). In the system, however, must be one powerful control unit with management. The unit is a type of “slave” and in your network needs a “master”. Can handle a maximum of 128 units connect client.


-4 ports of 10/100Base-TX, Auto-Negotiation (10/100 Mbps), IEEE 802.3 u, automatic detection of direct/crossover patch cable, each independent
-2 ports (F) connector (female), 75 Ohm, coaxial connection on the lead and a TV receiver. Port for TV receiver passively linked to supply and is functional even when the device is switched off
-až 128 vzájemně komunikujících jednotek na jediném koaxiálním vedení
-maximální vzdálenost mezi dvěma jednotkami 800-1500m (závisí na struktuře a kvalitě instalace, max platí pro kabel průřezu RG59)
-the current operation with the TV
-Qualcomm’s Atheros chipset family 7411, signal the speed up to 600Mbps, automatic adjustment of speed and modulation, OFDM modulation, adaptive, 896 of load-bearing
-frequency band 7, 5 MHz-65MHz
-the maximum attenuation for cables between the master and slave units: 65dB
-output power: 116dBuV
-the symmetric operation of synchronous duplex Ethernet bridge, transparent, independent of the protocols, operating systems, transparent, does not need any software
-support for 802 .1Q VLAN, IGMP, prioritizing 802.1 p, bandwidth control/shaper-set on the master
-external source, power supply 12V DC

Note that the ability to interconnect LAN ports on the slave devices with VLAN numbers do not need to use a separate router for each user. Just before the front-end router master unit, which can link with the IP address of the VLAN ID (today any Linux distribution, and all the advanced commercial routers). Or just one such router for up to approximately. 4000 LAN ports. If the transmission network provider allows the correct transmission of VLAN ID tag so that the router may not be located in the connecting building and can be placed directly in the headquarters of the CPI and to serve as a large number of users.
