3.11 Data interfaces
The LMS1xx has different data interfaces for the configuration and the transmission of mea-
sured values.
Important

It is only possible to output all measured values of a scan in real-time using the Ethernet
interface.

The data transmission rate of the RS-232 interfaces is limited. Therefore these inter-
faces are not suitable for transmitting scan data in real time.
3.11.1 Ethernet interface
The Ethernet interface has a data transmission rate of 10/100 MBit. The interface is a

TCP/IP interface. Full duplex and half duplex are supported.
The Ethernet interface allows the configuration of the LMS1xx as well as the output of
measured values.
The factory setting for the Ethernet interface is as follows:

IP address: 192.168.0.1

subnet mask: 255.255.255.0

TCP port: 2111 and 2112
If necessary, adjust the TCP/IP configuration for the Ethernet interface to enable a connec-
ted PC (client) to communicate with the LMS1xx via Ethernet: P

Important If you change the parameters for the Ethernet interface over the Ethernet interface, you
must first save the data in non-volatile memory in the LMS1xx and then restart the LMS1xx.
For this purpose there is the R
ESTART
button in SOPAS ET.
You will find a description of the electrical interface in section 6.2 “Connections of the
LMS1xx” on page 66 .
3.11.2 CAN
The CAN interf ace supports data transmissions between 10 Bit/s and 1 Mbit/s.
For data communication via CAN you must configure the LMS1xx so that it can
communicate with the host:
