Subject to change without notice
here without much mathematical expenditure to determine and
it can with these subnet mask up to 254 network elements (e.g.
measuring instruments, hosts/PC‘s...) in a network be operated
at the same time.
Often also a standard gateway is present in a network. In most
local networks is this gateway with the router to the Internet
(DSL router, ISDN router, …) …) is identical. Using this (gate-
way -) router a connection can be manufactured with another
network. Thus also network elements, which are not in the
same (local) network, can be reached and/or network elements
from the local network are able to exchange data with network
elements from other networks. For a network-spreading data
exchange the IP address of the standard gateway must also be
preset. In local networks, mostly the fi rst IP address within a
network for this (gateway -) router is used. Mostly routers in a
local network to be used as gateway have an IP address with a
„1“ in the last place of the IP address (e.g. 192.168.10.1).
8.2 Ethernet interface parameters at the oscil-
loscope
The Ethernet interface parameters are preset in the oscil-
loscope with activated Ethernet interface in the menu “SET-
TINGS“ “INTERFACE“ “ETHERNET PARAMETER“ to be preset.
The Ethernet interface parameters have to agree with the
software HMLab and/or the parameters of the Ethernet LAN
interface at the host (PC).
Reference! The preset IP addresses in the oscilloscope and the
host (PC) have to be different and be in the same subnet (ex.:
oscilloscope 192.168.010.010, PC 192.168.010.002, with subnet
mask 255.255.255.000).
With activated DHCP function the parameters IP address, sub-
net mask and gateway will be automatic by an existing DHCP
server in the network.
With deactivated DHCP function the parameters at the Ethernet
interface can be preset manually.
Reference! If the oscilloscope is connected by a network cable
directly with a host (PC), the DHCP function has to be deac-
tivated, since no network with DHCP server is present. Without
DHCP server no interface parameters can be made available to
the oscilloscope and the host (PC) automatically.

The highlighted parameter value is then preset with the „IN-
TENS“ rotation control to the desired value. The menu option
“Save“ in the Readout saves the preset interface parameters by
the oscilloscope and/or determined automatically after press
the menu option “Save“ with activated DHCP function and sto-
red until changed. The menu option “Defaults“ in the Readout,
restores the factory-installed preset interface parameters.
The represented interface parameters have the following
meaning:
IP:
The IP address of the oscilloscope (default setting:
192.168.010.010).
Subnet mask: The subnet mask marks the fi rm network quota
and the variable host quota of the IP address of
theoscilloscope (default setting: 255.255.255.000).
General is to be considered: Within a local network
(LAN) the preset subnet mask has to be alike
with all attached network elements. That applies
tooscilloscope and host (PC), if they are in the
same local network.
Gateway: The IP address of the gateway (e.g. an existing rou-
ter) in the network, in order to make a connection
possible with another network (default setting:
192.168.010.001).
IP Port:
For the software HMLab or for internally developed
TCP (or UDP) applications, can be set the used IP
Port. Thus the oscilloscope can be addressed via
the preset IP Port directly by an application e.g.
192.168.010.010:50000 (default setting: IP Port
50000). Port settings are possible within the range
of 1024 - 65535.
HTTP Port: The HTTP Port for Web browser (default setting:
HTTP Port 00080). Port settings are possible within
the range of 0 - 65535.
Transfer:
The transmission rate of the Ethernet interface
(default setting: Auto). In the preset „Auto“ the
highest possible transmission rate of the receiving
station is selected. If an automatic preset is not
possible, transmission rate and the transmission
method can be set manually to the following va-
lues: 10Mbit/s half duplex, 10Mbit/s full duplex,
100Mbit/s half duplex or 100Mbit/s full duplex. As
a check on RJ-45 socket the up-to-date preset
transmission rate of the Ethernet interface can
be read off in the Readout or from the two light
emitting diodes (LED). The yellow LED shines
with a transmission rate of 10Mbit/s. The yellow
and green LED shines with a transmission rate
100Mbit/s.
Link:
The status of the connection between the Ether-
net interface of the oscilloscope and the network
interface of a receiving station (connection active:
Yes, connection not active: No).
STOP
Reference!
The MAC address (network card address) of the
Ethernet interface can be queried over the menu
„Component tester
