9. Peripherals
9.1 Ethernet interface
The device has 2 Ethernet interfaces (Ethernet A
and B). The two Ethernet interfaces:
·Are connected in series with each other (a daisy-
chain connection can thus be realized).
·Communicate via one IP address.
Recommendation:
Use at least CAT5 cable!
Ethernet A
Ethernet B
Patch cable
ATTENTION
Material damage due to incorrect network
settings.
Incorrect network settings can cause faults in the IT
network!
Consult your network administrator for
the correct network settings for your device.

9.2 Daisy chain connection
With this type of connection, several devices
(hardware components) are connected with each
other in series. With the two Ethernet interfaces of
the UMG 801, the daisy-chain connection can be
implemented as follows:
INFORMATION
In this figure, the daisy-chain connection exists only
if:
·The supply voltage is present at the UMG 801.
·The UMG 801 has been started up.
Also note the connection interruptions during
restarts!
