LED Indicators Ethernet

In addition to the indicator and operating elements present in all device models (bar graph, buttons,
LEDs AUT, MAN, ADJ; see chapter 11.1 "Indicator and operating elements"), the Ethernet model in-
cludes the following additional indicators:
PWR LINK Rx/Tx
100 FDX BUF

Important notices for system integrators

Attention!
The notices provide initial information and describe the working principles of the optical data
transceiver with Ethernet.
The notices must be read by each user before the first commissioning of the DDLS 200 with
Ethernet.
Possible restrictions in the timing of the optical data transmission in comparison to copper-
based data transmission are described here.
Using the DDLS 200 for Ethernet, 10Base-T or 100Base-TX with 2Mbit is transmitted optically e.g. to
a moving rack serving unit where it is then converted back into 10Base-T or 100Base-TX.
The DDSL200 is connected to the Ethernet via a twisted pair port with an RJ45 connector or an M12
connector. An external switch reduces the data flow along the optical transmission path by filtering the
messages. Only messages for nodes located downstream of the optical data transmission path are
actually transmitted. The data throughput rate of the optical transmission path is max. 2Mbit/s.
