9. Peripherals
9.1 Ethernet interface
The device has 2 Ethernet interfaces (Ethernet A

·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

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!
