In both cases, you can address the LAN power sensor as follows:
●
Chapter 3.7.3.3, "Using hostnames"
●
Chapter 3.7.3.4, "Assigning the IP address"
To set up a network Ethernet connection
1. Connect the power sensor as described in
Chapter 3.7.3.1, "Connecting a LAN
By default, the power sensor is configured to use dynamic TCP/IP configuration
(DHCP) and to obtain the address information automatically.
If both LAN status LEDs are illuminated in green color, the power sensor is cor-
rectly connected to the network.
Note:
Establishing a connection can take up to 2 minutes per device.
2. If the LAN status LEDs show another state, no connection is possible. For possible
solutions, see:

"Troubleshooting for peer-to-peer connections"
Troubleshooting for peer-to-peer connections
1. Allow a waiting time, especially if the computer was used in a network before.
2. Check that only the main network adapter is active on the computer. If the com-
puter has more than one network interfaces, explicitly disable all other network
interfaces if you plan to utilize a peer-to-peer connection to the power sensor.
3. Check that the IP address assigned to the remaining main network adapter starts
with
169.254
. The IANA (Internet assigned numbers authority) has reserved the
range
169.254.0.0
to
169.254.255.255
for the allocation of automatic private
IP addresses (APIPA). Addresses from this range assuredly cause no conflicts with
any routable IP address.
4. Try to establish a connection to the power sensor with both the default hostname
and the hostname extended with
.local
, for example:
nrp6an-101441
nrp6an-101441.local
3.7.3.3
Using hostnames
In a LAN that uses a domain name system (DNS) server, each connected computer or
instrument can be accessed via an unambiguous hostname instead of an IP address.
The DNS server translates the hostname to the IP address. Using the hostname is
especially useful when a DHCP server is used, as a new IP address can be assigned
each time the instrument is restarted.
Each power sensor is delivered with a default hostname assigned. You can change the
default hostname.
