Installation
4.4. Connecting the Network Cable
The Network Port is an RJ45 Ethernet jack, for connection to a TCP/IP
network. Connect your 10Base-T cable to the Network Port. Note that the
NBB includes a default IP address (192.168.168.168) and a default subnet
mask (255.255.255.0.) When installing the NBB in a working network
environment, it is recommended to define network parameters as described in
Section 5.3.4.
Note: The NBB features a 10Base-T Interface. When connecting
to a 100Base-T interface, most router switches will autosense
to determine if the device is 100Base-T or 10Base-T, and then
configure the network interface accordingly. If your router switch
does not autosense, the network interface port must be manually set
to 10Base-T.
This completes the NBB installation instructions. Please proceed to the next
Section for instructions regarding unit configuration.
