7.1 Alternate methods of IP address assignment
7.1.2 ...Using ARP command
The prerequisite is a PC which is located in the same network
segment as the Web-Graph 1x Thermo-Hygrometer and on
which TCP/IP protocol is installed. Read off the MAC address of
the device from the nameplate (e.g. EN=00C03D0012FF). Under
Windows you will first ping another network station and then
use the command line described below to make a static entry
in the computer‘s ARP table:
arp -s <IP-Adresse> <MAC-Adresse>
e.g. under Windows:
arp -s 172.0.0.10 00-C0-3D-00-12-FF
e.g. under SCO UNIX:
arp -s 172.0.0.10 00:C0:3D:00:12:FF
Now ping the device again (in our example, ping 172.0.0.10). The
IP address is now stored in non-volatile memory.
!
This method can only be used if no IP address has as yet
been assigned to the Web-Graph 1x Thermo-Hygrometer,
in other words the entry is 0.0.0.0. To change an already
existing IP address, you must open the configuration menu from
your browser or use the serial method (see below).
