LED indicators DH+ / RIO

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 DH+/RIO model
also has the following indicators:

S3-1 On (1) = approx. 1.5 µs + 1.5TBit
S3-1 Off (0) = approx. 1.5 µs
= operation indicator
via switching input IN or hardware error
= no operating voltage
= data is being transmitted to the bus
the LEDs Tx and Rx flicker. At very
high baud rates (> 50kBit/s), flashing
LEDs Tx and Rx indicate faulty bus
communication.
= no data on the transmission line
= data is being received by the bus
the LEDs Tx and Rx flicker. At very
high baud rates (> 50kBit/s), flashing
LEDs Tx and Rx indicate faulty bus
communication.
= no data on the receiving line
