NXU-2B Operations Manual
3-12
3.4.4
Setting Unit IP Address
The first thing you should do is to set the IP address of the unit. The NXU-2B comes from the
factory with a default IP address set to 192.168.1.200. Set the address by typing:
MYIP <IP address>
Where <IP address> is the IP address of the unit in dotted quad notation. All configuration
commands are entered by a carriage return. In this example, if your desired IP address is
192.168.1.1 you would type MYIP 192.168.1.1 and press ENTER
3.4.5
Setting Unit Subnet Mask and Gateway Address
Now set your subnet mask using the SUBNET command. If you are using a gateway, set the
gateway address (the address of your router) using the GATEIP command. If on a LAN with no
gateway, leave the gateway address set at the default address 0.0.0.0.
3.4.6
Using DHCP to Assign IP Parameters
If you have a DHCP server on your network, you may configure the NXU-2B to obtain its IP
address, subnet mask, and gateway address via DHCP. Setting the NXU-2B IP address to 0.0.0.0
will cause it to attempt to contact a DHCP server on power-up. NOTE: Using DHCP is not
recommended for NXU-2B Server units since the IP address assigned by the DHCP server is not
generally known and is subject to change. If DHCP is to be used, it should only be used on client
NXU-2B units.
3.4.7
Setting VoIP Port (Optional)
The port used by the NXU-2B for receiving audio from the network which defaults to 1221.
Under normal circumstances, this should not be changed. The default value may be changed, if
necessary, by using the PORT command. Type PORT <port number> and press ENTER to select
a new VoIP port. The port number must range from 1 to 65535 and be different from the
command port.
3.4.8
Client/Server Selection
Whether the unit will be a client (a unit which can make and break connections) or a server (a
unit which only accepts connections from a client) will need to be decided. This selection is
made with the CONMODE command. CONMODE 0 configures the unit as a client, while
CONMODE 1 configures the unit as a server. For a client unit, you also need to set the IP address
and port of the corresponding server with the SRVRIP and SRVRPORT commands. For
example, if a client unit is going to be connected to a server NXU-2B at address 192.168.1.10
and port 1221, then the commands must be issued:
SRVRIP 192.168.1.10
SRVRPORT 1221
On the client unit, if you do not want the client unit to connect to a server automatically at power-
up then set the server IP address to 0.0.0.0 by typing SRVRIP 0.0.0.0.
