2.2 Connection settings
2.2.1 IP settings for sensor
All sensors are shipped with the factory default IP address of 169.254.23.33. This
address belongs to the Zeroconf addresses (as defined in IETF standard RFC 3927) so
that it can easily be reached from a stand-alone computer (figure 2.1), usually without
changing the network settings of the computer. This address will remain in the sensor
even after a different IP address has been set. The sensor answers in the address that
is first called up after startup.
Note: If there are more than one PR-33 in the same network, this address cannot be
used (section 2.2.3).
The IP address of the sensor can be changed through the instrument homepage (sec-
tion 2.4).
2.2.2 IP settings for stand-alone computer
When you start up a computer with automatical IP settings (DHCP enabled) in a net-
work with only the PR-33 sensor, the computer should automatically obtain an IP ad-
dress 169.254.x.x. In this case you can connect to the factory default address of the
sensor without any further changes in settings. If this does not work, please make sure
that your WLAN (Wireless network connection) is not active when you connect to the
sensor. If the WLAN is active, the computer’s Ethernet connection may not function as
expected. Also, obtaining the 169.254.x.x. address may take up to a minute.
If you still have difficulties in connecting to the sensor, you may check the IP address of
the computer by opening the command window (command prompt) and by typing the
command
ipconfig
at the command prompt (press Enter to give the command), see
figure 2.5 (in Mac OS X and Linux the same command is called
ifconfig
). The result
will give you your computer’s IP address. If the address does not start by 169.254,
you will have to manually configure the IP address of the computer to 169.254.23.34,
netmask 255.255.0.0.
For further troubleshooting, see section 2.3.1.
