In the example given below
the Dupline® installation uses
32 channels (FMK 32 of the
channel generator). There-
fore, the address setup of the
D 1230 5111 is compared with
the status of channel group
D. As soon as the status of
channel group D (provided by
the transmitter GGD 1550) is
equal to the address setup,
the disable output of the D
1230 5111 turns off. This
causes the FFD 1680 to trans-
mit the counter value on
channel groups A-B for dis-
play on the D6369 6475
(coded for channel groups A-
B).
Note: If DC-supplied D 1230
5111 receivers are used, the
length of the supply bus must
not exceed 3 m in order to
avoid disturbance unbalanc-
ing the Dupline®.
Mode of Operation
8-channel receiver with de-
multiplexed outputs for ena-
ble and disable functions.
The receiver continuously re-
ceives the status of 8 chan-
nels on the highest channel
group of a Dupline® installa-
tion (e.g. channel group P if
128 channels are selected on
the channel generator). The
status of these 8 channels is
compared with the address
selected by the DIP switch
selector inside the D 1230
5111. As soon as the trans-
mitted channel status is equal
to the selected address, the
two outputs change state (en-
able output turns on and dis-
able output turns off).
This module used in connec-
tion with transmitters for ana-
logue signals (type FFD 15..)
allows the transmission of 255
individual analogue values on
one channel group. The D
1230 5111 can be used for all
Dupline® transmitters that have
enable or disable inputs, e.g.
FFD 15.., FFD 16.. or SPEC 918.
