Installation Procedure
Note that the examples below assume that the Ethernet Switch used does not support
WiFi, and a Router with WiFi capability is required in order to communicate with
smartphones and tablets for control purposes.
Setting the Ethernet Switch & Router to the same Subnet as C2G Devices:
The C2G Network Controller comes with two Ethernet ports. LAN 1 is configured
with a static IP address which is 192.168.168.50. LAN 1 port should be connected in
to the same network switch where all the C2G equipment is connected. Note that
LAN 2 port is configured as a DHCP client, and can be utilized for control purpose.
The C2G AV over IP Encoders (TX) and Decoders (RX) are set to support DHCP by
default. When no DHCP server is available the AV over IP Encoders and Decoders
fallback to a static IP address of:
•192.168.168.62 (for the 29975 Encoders)
•192.168.168.63 (for the 29976 Decoders)
These C2G products (Network Controller and the AV over IP Encoders & Decoders)
work in conjunction with a PoE (PSE) Ethernet Switch (supporting IGMP and Jumbo
Frames) and a Router of your choice with WiFi capability to be able to communicate
with a smartphone or tablet. Also, in the case where one Ethernet Switch does not
have sufficient ports for the number of AV over IP Encoders and Decoders to be
connected, then it is recommended that the Ethernet Switch be a stackable Ethernet
Switch. The use of a smartphone or tablet to manage the C2G devices with the C2G
AVoIP Control App (model: 29986) is the preferred method of control, however C2G
devices may also be managed via the Network Controller web interface.
In order for the DHCP server within the Ethernet Switch to support the C2G device
subnet, set the static IP of the Ethernet Switch to 192.168.168.1 (recommended
setting). Refer to the Ethernet Switch manual for instructions on how to accomplish
this. The Router with WiFi capability, must also be placed on the same subnet as the
C2G devices and it should be set with a Static IP address, we recommend using a
Static IP address of 192.168.168.2. Refer to your Router documentation on how to
accomplish this.
Setting C2G Devices, Ethernet Switch and Router to an Existing Subnet:
If the C2G AV over IP devices are being installed in an existing environment that has
a working subnet already configured that cannot be easily changed, then the subnet of
the C2G devices, the Ethernet Switch (if a new Ethernet Switch is required), and the
Router with Wifi (if a new Router is required) must be changed in order to match the
existing subnet. For this case we will use 192.168.2.x as an example subnet already in
place and which must be supported. Note that this is only an example and may not
necessarily reflect your actual subnet address.

Page 10
If the Ethernet Switch does not already reside in the example subnet of 192.168.2.x,
then set the static IP of the Ethernet Switch to a free static IP address (for the sake of
this example we will use an IP address of 192.168.2.1). Refer to the Ethernet Switch
manual for instructions on how to accomplish this. C2G also has example guides
specific to the Cisco SG350 Series, Luxul AMS-1208P Series, and NetGear S3300
Series, which may be found on the C2G website.
If the Router with WiFi does not already reside in the example subnet of 192.168.2.x,
then set the static IP of the Router to a free static IP address (for the sake of this
example we will use an IP address of 192.168.2.2). Refer to your Router
documentation on how to accomplish this.
The C2G AV over IP Encoders and Decoders are set by default to support DHCP and
will automatically be set to the subnet specified by the DHCP Server. These units need
only be physically connected into the network as described in their respective
Installation Guides and by using the 29977 Network Controller for HDMI over IP to
discover them. But before the Network Controller can be used, the new Network
Controller subnet must also be set.
To change the subnet of the Network Controller requires a two-step process:
Process 1: Configuring the IP address of the Network Controller
Process 2: Physically installing the Network Controller in the network
Note:
• An example subnet address of 192.168.2.x of the existing network on which the Network
Controller will be installed is assumed for this example process.
• The Network Controller LAN 1 port comes with a static IP address of 192.168.168.50 and
with DHCP disabled. This process explains how to change it to the example subnet of
192.168.2.x.
Process 1: Configuring the IP address of the Network Controller
Refer to Figure 4 and Figure 5.
1. On the back panel of the Network Controller:
A. Plug the supplied power adaptor into the DC power jack. Ensure that the other
end of the power adaptor is plugged into a power socket.
B. Ensure that the power switch on the front of the unit is ON position (front
button • pressed in).
C. Connect one end of an Ethernet cable to the LAN 1 Ethernet port. Ensure that
the other end of the Ethernet cable is connected to a computer.
Refer to Figure 6.
2. On the computer to which the Network Controller is connected, open up an
Internet browser (Explorer, Chrome, Firefox, etc.) and type the following address
in the address bar near the top of the screen:

Static and LAN 2 as Dynamic (DHCP).
14. In the LAN 1 IP address field, type the first 3 entries of the IP address of the
network subnet on which the Network Controller will be installed, which in our
example is 192.168.2.x.
For example, type the following in the Network Controller IP address field:
192.168.2.x
Where xin our example can be any number from 3 to 254, and since “1” was used
above for the Ethernet Switch and “2” was used for the Router, then for this
example we will select “5” for a Static IP address of 192.168.2.5, see Figure 15.
Just make sure the Static IP address for the Network Controller does not conflict
with the Static IP address of the Ethernet Switch and the Router or any other Static
IP address already pre-assigned in the given network.

Ethernet Web Interface –Device Management
The Ethernet Web interface allows the user to manage the Network Controller and the AV
over IP product family of extenders remotely from a Windows based computer. Make sure
the computer is set to a Static IP address in the same subnet, which in our example is
192.168.2.x. Follow steps 4, 5 & 6 in section 3.3 on how to accomplish this, but set using
the subnet 192.168.2.x
Ensure that the computer is connected by an Ethernet cable to the network router on which
the Network Controller is physically installed. Open up an Internet browser (Explorer,
Chrome, Firefox, etc.) and type in the Network Controller IP address in the address bar
near the top of the screen, such as, which in our example is 192.168.2.5:
192.168.2.5/mnc/
NOTE:192.168.2.x represents the first three IP address entries of the network subnet
on which the Network Controller is physically installed.
