W&T Assigning the IP address
2�3 Assigning the IP using the ARP command
Requirements
This method can only be used if the Com-Server does not al-
ready have an IP address, i.e. the entry is 0.0.0.0. To change
an IP address, use one of the other methods described in
this section or use the configuration menu over Telnet. If the
Com-Server has any other value, this access is disabled.
When the factory setting is in effect as well as after a manual
changeover from static to DHCP, the method for assigning
the IP described in this section functions only after a delay of
approx. 2 minutes after a reset or after power-up.
This method does not work across networks, e.g. through
routers. This means the PC and Com-Server used for assi-
gning must be connected to the same physical network seg-
ment. Only IP addresses whose Net-ID is identical to that of
the assigning computer can be assigned.

To avoid unintended changes to the IP address, the
DHCP client of the Com-Server is automatically deactiva-
ted when configuring using a static ARP entry.
Step 1
Read off the
Ethernet address of the Com-Server from the stik-
ker on the side of the housing.
EN = 00c0:3d01:0203
5xxxx [TB number
and/or model name]
OK +0123456789
Ethernet address
Insert a static entry into the ARP table of the computer using
the following command line:
arp -s [IP address] [Ethernet address]
i
Older Windows systems
only accept a static ent-
ry if there is a dynamic
one already present.
Here you should first
ping another network
station.
