Things to know about the ethernet connection
-
The following configuration is for testing a point-to-point connection.
-
The IP address must differ in the last octet.
What does “ping” mean and how is it done?
- The console is opened via Start, Run, and entering CMD.
-
The command syntax consists of: PING space IP address e.g. ==> ping 10.11.1.77
-
The service must be activated and supported by the network.
-
The firewall must allow the command; if necessary, it must be disabled during use.
-
Ping can be used to test whether the JUMO LOGOSCREEN nt is correctly connected to the network.
-
This requires knowledge of the IP or host name of the device.
-
If the host name is known, a PING can also be sent to it.
-
The command syntax consists of: PING space host name, e.g., ==> ping jumogeraet
What is the significance of the LEDs on the network card of the JUMO LOGOSCREEN nt?

off ==> 10 Mbit/s
Middle LED (red):
Link and activity LED
off ==> no connection;
on ==> connection available;
flashing ==> connection available and activity on the line
Right LED (green):

on ==> full duplex;
off ==> half duplex
Which connection cable should I use and when?
How do I configure the Ethernet interface of the JUMO LOGOSCREEN nt appropriately?
-
After the power is turned off and on again, the JUMO LOGOSCREEN nt automatically receives a free IP address from the assigned range.
-
Since the recorder normally operates with a fixed IP address, it can no longer be accessed. In many cases, the IP address also changes when the power is turned off and on again.
For this reason, DHCP should only be used in conjunction with DNS. The device is assigned a HOST name. The DNS server maintains the assignments of the HOST names to the IP addresses. -
The JUMO application programs can work with the HOST name.
How is an entry in the device list created by the user programs?
