12 The s88-Mode
If a model railway layout is to controlled automa-
tically from a computer programm, then the com-
puter will need feed-back information as to which
section of track a train is to be found. Only in this
way can signal or points which have been passed
can be switched, or trains stopped or started
accordingly.
The so-called s88 answer-back modules supervi-
se the sections of track and transmit their condi-
tion "this section is occupied by a train" or "this
section is not occupied by a train" back to the
central unit. The computer control mechanism
can receive these pieces of information from the
interface and use them to coordinate its control
commands accordingly. S88 answer back modu-
les are not available from FLEISCHMANN. Please
ask your specialist dealer.
A total of 31 s88 modules (addresses 1 to 31)
each with 16 inputs can be connected into the
answer-back bus of the TWIN-CENTER and addi-
tional external modules (addresses 32 to 128)
connected via the LocoNet. As a whole, it is pos-
sible to have a total of 2048 inputs. The highest
module address is 128.

12.1 Workwise

In s88 mode the connected answer-back modu-
les will be requested for information and their
answers indicated.
As opposed to other digital central units the
TWIN-CENTER stores the answer-back signals
internally. The computer then only needs to ask
an internal information flag whether there have
been any alterations.
In order to carry out this request and answer
sequence as quickly as possible, the TWIN-CEN-
TER needs the information as to how many
answer-back modules are actually connected to
the answer-back bus.
And here is how to do it:
• Press the [menu] key

• Press the [mode] key
• Search through using the [↓] key until

• At the input position, enter the number
• Return to operation with the [menu] key
A maximum of 31 modules can be connected in.

12.2 Setting s88-Mode

The TWIN-CENTER has different operating
modes. Available at the present time are: keybo-
ard, memo, s88 monitor and programming mode.
With each depression of the [mode] key the ope-
ration mode will be altered and briefly shown in
the display. Press the [mode] key until the indica-
tion "s88-mode" appears in the display, alternati-
vely the keys [mode] and [3] (see chapter 8.2).
The indication in the centre of the display will
change according to the selected mode.

12.3 Altering the key allocation

After switching the TWIN-CENTER on, in s88
mode, the module with the address 1 will be dis-
played.
Should other modules be indicated, so the modu-
le address in use can be changed by the TWIN-
CENTER.
By pressing the [menu] key this indication will
appear in the display:
