DSE
INSTALLATION
X2 and X4, Ethernet connections
There are two 4-pin M12 sockets (D-coded) on the back for the Ethernet connections.
These are labeled X2 and X4 ([3] and [5] in Fig. 5.1). The pin assignment is shown in
Fig. 5.6.

You can operate the DSE with all standard M12 connection cables. Make sure that the
coding is correct, and use only CAT5 cables.
For applications to meet EHEDG requirements, HBM offers the accessories described in
section 3.3, page 10, which also includes EHEDG-compliant cable sets. You will find them
at

Important
You can make a maximum of one network connection. Multiple connections are not
possible. If you try to establish another connection, it will be rejected with the error
message "Connection to device lost".
5.2 Shielding and grounding design
The supply connection, as well as the sensor signal and communication cables, must be
installed in such a way that electromagnetic interference does not adversely affect device
functionality. So you must use shielded cables to connect the sensor signal and commu­
nication cables. Interference on the shield must be grounded in a controlled way outside
the device.
Shielding
When using a shielded cable, the shield is routed through the connector housing. This
shields your system.
Grounding
If you need to ground the DSE, use one of the two fastening points. When installing the
ground, make sure that it is in compliance with EHEDG where required.
