10.5 LED indicators Ethernet
In addition to the indicators and operational controls present in all device models (bar graph, buttons,
LEDs AUT, MAN, ADJ; see chapter 11.1 "Indicators and operational controls"), the Ethernet model
also has the following indicators:

10.6 Important information for system integrators
Using the DDLS 200 for Ethernet, 10Base-T or 100Base-TX with 2MBit is transmitted optically e.g. to
a moving conveyor system where it is then converted back into 10Base-T or 100Base-TX.
The DDSL 200 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 participants located downstream of the optical data transmission path
are actually transmitted. The data throughput rate of the optical path is max. 2MBit/s.
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 time behavior of the optical data transmission in comparison to
copper-based data transmission are described here.

LED PWR: green
= operation indicator.
green flashing= transmitter / receiver unit switched off
via switching input IN or hardware error.
off
= no operating voltage.
LINK LED: green
= LINK OK.
off
= no LINK present.
Rx/Tx LED: green
= data is being received by the bus.
red
= data is being transmitted to the bus.
orange
= data is being received by the bus or
transmitted to the bus simultaneously.
off
= no data is being received by the bus or
transmitted to the bus.
100 LED: yellow
= 100Base-Tx connected
off
= 10Base-T connected
FDX LED: yellow
= full duplex (Full-Duplex)
off
= half duplex
BUF LED: yellow
= internal buffer (Buffer) full,
message rejected.
off
= message not rejected.
