Wodasign EOC Indoor Slave with WiFi router - EOC1121R4WL, 600Mbps, 4*LAN, 2*F, WEB Management, VLAN, IGMP, QoS ...

Old EOL version - please use new EOC slave with 300Mbps WiFi speed and better WiFi coverage!!!


Wodaplug EoC product is focused on the use of existing cable television (CATV) infrastructure for Internet access or broadband data transmission for the purpose of being compatible with the existing CATV (or sometimes satellite television) broadcast signals simultaneously transmitted on the same cable.

EOC1121R4 series are for NGB next generation broadcast network, especially for Cable TV Operators. It is an advanced end equipment to carry out family bandwidth data access. EOC1121R4WL is based on P1901 International Standard Protocol and HomePlug AV Protocol, with low-band and support big line-loss, long transmission distance.

The built in WiFi based on the single chip AR9331 which integrates an 802.11a 1x1 MAC radio with internal PA and LNA. It supports 802.11n operations up to 72mbps for 20MHz and 150Mbpcs for 40MHz channel respectively, and IEEE 802.11b/g data rates.


 Based on Qualcomm INT7411L chipset solution of HomePlug AV technology
 Work at low frequency between 7.5MHz~65MHz without influence on CATV service
 Physical layer speed is 600Mbps and Max MAC layer throughout is 300Mbps
 Support data encryption for both uplink and downlink
 Support 4*10/100Mbps Ethernet ports auto-negotiation function
 Support slave(CPE) isolation
 Support VLAN configuration based on slave’s Ethernet ports and 802.1q
 Support bandwidth(speed) limitation for both uplink and downlink
 Support QoS configuration based on slave port or VLAN
 Support broadcast storm control
 Support data packages count
 Automatically distribute configurations to newly connected slaves, available to use as soon as correctly connected and power on
 Support WEB,CLI and SNMP management
 Support on-line upgrading

default IP for management : , new SW version 1,03 comes with default IP.

For the software, there is no difference between the old and new slave. Upon different usage, the new version have two login information. The end-user user name and password both are "admin",
while for super admin, the user name is "administrator", the password is"cd16857lkv19". The full access and complete setting in Web could be realized via the super admin. If username:administrator pwd:cd16857lkv19 have no effect, please try: user name: adminisp , pwd: adminisp , this super admin login is used in latest SW versions
The new version wifi slave is more flexible in the application than before. On the hardware revision, we add the 8306E switch chipset in the modem. It can controls the STB1 and STB2 ports which used as the Ethernet ports to setting the VLAN, rate-limiting, configuration,etc.
The LAN1 and LAN2 have the router feature which support the PPPoE. Moreover,the two mode can work at the same time.

EoC Description

The EoC (Ethernet over COAX)provides Ethernet Access through Coaxial Network, offer Cable TV signal transmission for Operator based on existing Cable network as well as Broadband Data Access. In Network Application, EoC include Head End Equipment called Master and Terminal Equipment called Slave, one Master can support 256 Salves, network structure can be star type or tree type.

The product of EoC master which can provide the transmission of broadband data service via coax, which is suitable for application in a wide range of both residential (in-home) and commercial (offices, apartments, hotels, warehouses) network applications in which the coax can be utilized. There is never any need to install new wires. These outdoor devices enable the effortless creation of a high-speed network that supports video, voice and data.

The product of EoC slave for end-user that work with EoC master devices to establish Ethernet transmission channels over coaxial cables.

CD5204WL is the EOC slave based on HomePlug AV solution for Ethernet access over coax. It works together with EOC master which is on HomePlug AV solution basis as well to construct a two-layer Ethernet data transmission channel on CATV coaxial cable, providing the Ethernet access service over the existing coaxial cable networking.
CD5204WL is adopted with the Qualcomm INT7411 chipset solution and OFDM modulation technology of high interference resistance, taking up low frequency between 7.5MHz and 65MHz to transfer data. Its physical layer speed is 600Mbps, while the maximum MAC layer throughout is 300Mbps. It is built-in high isolation filter as CATV RF and EOC signal mixer, the EOC signal and CATV signal in 87~862MHz can run on one cable without interference.
CD5204WL is a slave with 4 Ethernet ports and Wifi.



1.  what is template 301 (and 302), I can't find it in the list of template and modify it?

Template function is for user configure the slave convenient. There are a default template named “1”,  is for the all slave as a default configuration. You can modify the template 1 in the SlaveàTemplate.

As you enter a slave configuration windows (it use the template 1), when you changed the configuration, the system will save a private template for this slave. The private template number will be 300+Slave ID. The private template is used only for this slave.

2.  how many admins can be loged in? Where can I find loged in users?

No limit now. No record for it.

3.  if I understad right, WAN means interface to WIFI module (oposite to port3) not the RF interface?  Due to this STB1 (port1) and STB2 (port2) interfaces are always in bridge mode with or without VLAN?

Yes. WAN is connect to the port3.

STB1(Port1) and STB2(port2) is always in bridge mode.

STB1, STB2 is out from the 8305E switch chipset.

internal structure

4.  if i'am right in 3, why in WAN configuration of a slave over master web there are 4 LAN ports? In WAN setting from direct Slave web are only ports PORT1 and PORT2 that means LAN1 and LAN2 I think.

Because the WIFI module support 4 port max. In this slave, it have 2 ports LAN1 and LAN2. In other type , it have 4 ports. The WIFI management window display LAN1, LAN2, LAN3, LAN4 is compatible the 4Port product.

We will distinguish between different product in late version.

5.  what does it mean PIB and NVM?  - this we can reply but maybe your reply will be better :-) 

NVM is the software for 74 chipset.

PIB is configuration file of chipset.

6.  where is connected router inside the box?

Please see figure in 2.

7.  where are VLANs processed? 

Slave - Online - Click the MAC you want to configure , enter the window as below.

vlan config


8.  when I set management VLAN I can't set dynamic IP resp. I can but without effect, eth0 has no IP. The DHCP server was configured properly, there was no DISCOVER for DHCP from master.

This version do not support the DHCP+VLAN function.

It only support DHCP (no VLAN) and Static IP (VLAN or not).

9.  I can't disable SNMP on master

Software design so. It do not support disable SNMP.

10.  Enable web access in WAN Conf of a slave over master web always fails.

Master and WIFI used the VLAN 4093 for OAM. Please try add this VLAN.

We will try to optimize it to configure in default.

11. Change setting in WAN Conf of a slave over master web doesn't work. I set mode to route and after Apply I see change it to bridge etc, etc, etc. I'm not able to set what i want.

You need saving configuration as below.
