Splitter mode
In this mode all data arriving at Port C are passed to Ports A
and B (C
r
A und C
r
B).
Data arriving at A and B are passed to C. Only one
communications line may however be active in this direction (A
r
C oder B
r
C). The prerequisite for establishing such
feedback channel is that no data have arrived at the competing
port (B or A) since the set reverse time.
If feedback channel is open (A
r
C oder B
r
C), all data received
at the competing port (B or A) are rejected. Even is a feedback
channel active, data received at C are passed to A and B. The
connection is closed if no date are received at the active port
during the set reverse time.
LEDs „A“ and „B“ on the front panel indicate an active
communications path.
This mode supports neither hard- nor software hand-
