D&B D80 - Ethernet Port and Network Topologies

4.3.4. ETHERNET (Dual Ethernet port)
A Dual Ethernet port with a built-in 2-port Ethernet switch
(10/100 Mbit/peer-to-peer) is provided enabling remote control
via Ethernet and allows the following physical network topologies:
– Star topology
Recommended standard,
– Daisy chain topology
For a maximum of three devices,
– or a combination of both topologies.
Note: In a daisy chain topology, if one device fails or is
switched off, this also affects all subsequent devices which are
then no longer connected to the network either.
A detailed description of remote control via Ethernet is given in
the technical information TI 310 (d&b code D5310.EN) which
can be downloaded from the d&b website at
www.dbaudio.com.
LED indicators
The two LED indicators above the respective connector in use
indicate the following states:
Green
Illuminates permanently when the device is connected
to an active network and flashes as long as a data
stream is transmitted.
Yellow – Is off when the speed is 10 Mbit.
– Illuminates permanently when the speed is
100 Mbit.
