4.2.3 Ethernet option
Ethernet connection
An IEEE 802.3 compatible connector on a screened RJ45 plug on the rear side of the
device is available as a network connection. The device can be connected to a hub or
switch via this connection. The pin assignment corresponds to a standard MDI interface
(AT&T258), so that a 1:1 cable with a maximum length of 100 metres (328 ft) can be
used here.
Caution!
Only one interface can be used at any one time (Ethernet or RS 232 / RS 485).

LED description
Next to the Ethernet connection (see rear of device) there are three light emitting diodes
which indicate the status of the Ethernet interface.
• Yellow LED: when the device is transmitting data it flashes irregularly, otherwise is
continuously on.
• Green LED: when the device is receiving data it flashes irregularly, otherwise is
continuously on.
• Red LED: is on when the device is connected to a network. If this LED is not
illuminated then communication is impossible.
Operating location
The operating location of the device should be selected such that the network-specific
maximum permitted cable length of 100 metres (328 ft) is not exceeded.
Please ensure that all connections are inserted only when the end devices are switched
off.
4.3 Degree of protection
The device meets all the requirements of ingress protection IP54
4.4 Post-connection check
