Introduction / Safety Information:
You have purchased the feedback module RM-DEC-88 for your
digital model railway.
The RM-DEC-88 is a high quality product which is supplied
within the Digital-Professional-Series of Littfinski
DatenTechnik (LDT).
We are wishing you having a good time using this product.
The finished modules come with a 2-years warranty.
•Please read the following instructions carefully. Warranty will
expire due to damages caused by disregarding the operating
instructions. LDT will also not be liable for any consequential
damage caused by improper use or installation.
Connecting the module to your digital
layout:
•Attention: Please switch off your model railway by
disconnecting the transformers from AC-current before
starting any installation.
•Connect the 6-pole plug to the Märklin-INTERFACE,
Märklin-MEMORY, Intellibox or TWIN-CENTER or existing
s88 feedback modules with the direction of the
connection cable to the bottom side. The plugs of further
connected feedback modules have to be connected in a
way to the 6-pole pin-plug-bar that the cable will be
directed away from the pc-board. The white marking at
one side of the pin-plug-bar has to correspond to the
white single wire of the s88-bus cable of the following
modules.
General Functions:
The feedback module RM-DEC-88 with 16 inputs is 100%
compatible to the s88.

RM-DEC-88
The feedback module RM-DEC-88 is suitable for decentralized
installation below the model railway layout. There are 4 bores
available for quick and easy installation.
The modules can be connected to each other by a bus-cable of
75cm length. In case this distance has to be extended it is
possible to order a 2 meter cable extension under order code
Kabel s88.
Connection to Märklin-Memory /
INTERFACE, Intellibox / TWIN-CENTER or
High Speed Interface HSI-88:
Up to 3 feedback modules can be connected to each
MEMORY.
The feedback signals of up to 31 modules can be evaluated by
connection to Märklin-INTERFACE, Intellibox or TWIN-
CENTER and HSI-88.
After switching on the power to the digital system the feedback
modules will be numerical identified at the sequence as they are
connected to the central unit.
For example, the first feedback module directly connected to
the MEMORY will be addressed to the key-group A1 to A8.
Contacts 1 to 8 of the MEMORY will perform switching tasks
(like a request of a drive-track) whereas contacts 9 to 16 are
responsible for circuit release (e.g. hold tracks occupied).
Märklin-INTERFACE, Intellibox or TWIN-CENTER and HSI-
88 do not use this kind of differences of subdivisions at
switching and release. All 16 inputs have equal access
(activated or not activated).
If you intend to extend your model railway with RM-DEC-88
feedback modules you can easily combine these with any
existing s88 modules.
Please make sure that the digital layout has been switched
off when connecting the decoders with the 6-pole plug.
Check carefully the correct orientation of the plugs.
