1. Introduction
With the G.hn Bridge G4204C you can easily set up a local
network via existing coaxial cables. It is compatible with
G4201C - both models can be combined in a network as
desired.
The modems can be used "point-to-point" as well as
"multipoint-to-multipoint" - up to 16 modems are possible
in the network.
The devices are also suitable for distributing fibre
connections from the ONT to the router via existing coaxial
line ("point-to-point").
The devices can use any type of coaxial cable for data
transmission and achieve a speed of approx. 1600 Mbps.
This bandwidth is shared between all connected modems.
* The G4204C modem can also be used in the client configuration on
manageable G.hn switches (G4200C, G4200-4C/8C). This enables
networks with up to several hundred modems with very high total
bandwidth and central administration.

8. Installation notes
The G.hn modem can be connected directly to a coaxial cable or to a wall socket (multimedia socket). When connecting
to a wall socket, use the DATA connector or an equivalent one that has return channel capability in the frequency range
5-200MHz.
The coaxial cables can be connected via splitters, pass-through wall outlets, feed-in crossovers and SAT multi-switches
with return channel capability.
Maximum range of the G.hn connection depends essentially on the type of cable used. Typical values for RG-6 coaxial
cable (8dB attenuation at 200MHz): maximum G.hn bandwidth of 1600 Mbit/s is possible up to approx. 300 metres, the
G.hn connection - up to approx. 1300 metres.
In the web interface of each modem, the negotiated bandwidths to all other G.hn bridges in the network can be queried
(see point 10).
Parallel operation with SAT-TV (950-2150MHz) and with DVB-T2 (470-690MHz) on a coaxial line is possible without
restrictions.
Parallel operation with cable TV (DVB-C) is possible in the frequency range from 250MHz.
Parallel operation with cable Internet (DOCSIS) is not possible because the frequency ranges of G.hn (2-200MHz) and
DOCSIS (5-862MHz) overlap.

9. Administration
10. IP address
The devices do not require IP addresses from the local network segment during operation, because they transmit the data
traffic via the MAC addresses. In the factory setting, they do not obtain any addresses from the local DHCP server.
If desired, static IP addresses can be configured or the DHCP client can be activated ("IP" menu in the web interface).
11. Query of the negotiated bandwidth
The bandwidths negotiated from one G.hn bridge to all other G.hn bridges in the network can be queried via the web
interface. The values shown are gross data transfer rates at the physical layer (PHY). The tranfer rate on the application
layer is approx. 15-20% lower.
IP-Adress: 192.168.10.253. Login passwort: paterna
Login via web interface
Connect your computer to the G.hn modem via the GE port.
Assign a fixed IP address to your computer, e.g.
192.168.10.100 (network mask 255.255.255.0).
Open a web browser and connect to 192.168.10.253
Log in with the default password: paterna

12. VLAN usage in the network
The devices support VLANs according to 802.1Q standard.
The VLAN tags are forwarded transparently by default. External Ethernet switches can be used to manage VLANs.
13. Multicast IP TV
14. Warranty
We provide a 24-month warranty on all products purchased from us. You can find complete warranty conditions at
https://gigacopper.net/web/en/Guarantee_declaration.pdf
For broadcast of multicast IP TV in the network, "IGMP
Snooping" must be activated in the multicast configuration.
