Mode of Operation
D 9091 0210 is a Dupline
modem interface for easy
control of Dupline
networks
through the telephone lines.
Configuration of the interface
is done by means of the con-
figurator type D 9080 or by
means of a personal compu-
ter running the terminal emu-
lator software D 9091 SW01.
The modem interface features
3 main functions for which it
can be configured: public line
mode, private line mode and
RS 232 interface.
For status indication 4 LEDs
are used:
Call initiate (CI): to identify
the dialling modem.
External Dupline
OK (EXD):
indicating that the connect-
ed Dupline
is working pro-
perly.
Modem connection OK
(CON): showing that con-
nection is established be-
tween the 2 modems.
Power supply ON (PWR): to
indicate that power is appli-
ed to the unit.
The Run/program push but-
ton (5) (accessible with a pen
through a hole on the right
side of the housing) is used to
switch the interface to confi-
guration or Run-mode. When
this push button is held down
for 5 s the interface changes
mode. Configuration mode is
indicated by flashing of the
three LEDs - CI, EXD and
CON.
The voltage selector switch (6)
(only on D 9091 0210 230) is
used to adapt the unit to the
supply voltage.
Note: The D 9091 0210 230 is
factory set for 230 VAC.
To change the supply voltage
proceed as follows:
1. disconnect the power
2. remove the 4 housing
screws at the bottom of the
unit.
3. lift off the housing top cover
4. move switch (6) into po-
sition for selected voltage
5. reassemble the unit
6. change supply voltage label
on the rear of the housing
7. connect power cable to
power connector (7).
The relay output (8) deener-
gizes whenever one of the fol-
lowing problems is detected:
Transmission breakdown
Continuous reception of
corrupted data
External Dupline
off-line
Reception of an alarm call
The Dupline
transmission
inhibit input (10) is used to
reset the data buffer and igno-
re the data received from the
counterpart station. For more
details, refer to the description
in the manual.
