Case 1: You are setting up a local network between your PC and your meas-
urement device
You may require an Ethernet cross cable if you want to connect only
the PC and the device. But most PCs today do not need a cross cable
any longer; the interface is automatically reconfigured accordingly. If
you use an Ethernet hub or Ethernet switch, connect the PC and
devices to it (regular Ethernet cables).
Then, set the addresses on the devices. For example, assign the IP
address 192.168.100.1 to your PC and the following addresses
192.168.100.2, 192.168.100.3, etc. to the
Delphin
devices. The
address ranges 192.168.xxx.xxx are set aside for such internal net-
works, which is why they do not conflict with addresses on the Inter-
net, even when your PC uses another Internet access.
Case 2: Your PC is connected to an Ethernet network, and your
Delphin
device is to be connected to the same network
Contact your system administrator to obtain an Ethernet address,
which you then set on the device.
DHCP Server
Use this function to set up a DHCP server that assigns to all devices on the
network (
Subnet
) a valid IP address. Enter a start and end address for the
range of addresses to be made available.
Example
Start
:
192.168.240.10
,
End
:
192.168.240.50
. With this setting,
addresses from 10 to 50 can be assigned, that is, 41 users can receive
addresses automatically.
The first three groups of digits must be identical for the start and end. The
maximum range possible goes from 1 to 255.
The settings for
IP address
and
Net mask
(subnet
mask) on the left-hand side must match the settings for
the
DHCP Server
, for example, identical digits in the
first three groups of digits of the IP addresses.
The
IP address
must be outside the range specified for
the
DHCP Server
.
Speed and duplex
Generally, you should use
Auto negotiation
. This way, the adapters or Eth-
ernet switches involved will negotiate appropriate settings.
Problems may occur during auto negotiation in rare cases that interrupt
the transfer, because an attempt is made over and over again to find
optimal settings. In such cases, make the setting dependent, for example,
