Access NR-04A with its Default IP Address
The NR-04A is preconfigured with a static IP address: 192.168.101.50.
However, the IP address will only be used when there is no DHCP server
present in the network. If there is no server, the NR-04A will turn on its DHCP
server function and act as the DHCP server in the network. Users have two
options to connect to the NR-04A:
1. Connect the PC directly to the NR-04A using a crossover CAT5 Ethernet
cable
2. A PC can use a switch or hub to connect to the NR-04A over the
network
