2. If the network status LEDs indicate another state, no connection is possible.

Troubleshooting for peer-to-peer connections
To check the network connection:
1. Check that the assigned IP address of the used 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 are guaranteed to
cause no conflicts with any routable IP address.
2. Try to establish a connection to the R&S
NRPM3N with both the default host-
name and the hostname extended with
.local
, for example:
nrpm3n-101441
nrpm3n-101441.local
6.3.5.1
Using hostnames
In a LAN that uses a domain name system (DNS) server, each connected com-
puter 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 sensor module is delivered with a default hostname assigned. You can
change the default hostname.
Default hostname
The default hostname follows the syntax:
<device name>-<serial number>
, where:
●
<device name>
is the short name of your sensor module.
For example, the
<device name>
of R&S
NRPM3N is
nrpm3n
.
●
<serial number>
is the individual serial number of the sensor module. The
serial number is printed on the name plate at the rear side of the sensor mod-
ule. It is part of the device ID printed above the barcode:
