>> finished module <<
The Light-Interface for the parallel interface (LPT) of a
computer combines together with a minimum of one
Light-Display-Module or Light-Power-Module the
hardware for the PC-Light Control Light@Night.
It is possible to connect up to 7 Light-Display- and/or Light-
Power-Modules onto each Light-Interface LI-LPT.
The lighting effects (neon lamps, gas street lamps, flashing
blue light, light chains, traffic lights and others) can be assigned
to a maximum of 280 outputs.
Suitable for analog and digital model railways.
This product is not a toy! Not suitable for children under 14 years of age! The kit
contains small parts, which should be kept away from children under 3! Improper
use will imply danger of injuring due to sharp edges and tips! Please store this
instruction carefully.

Introduction/Safety instruction:

You have purchased the Light-Interface LI-LPT for the PC-Light
control Light@Night for your analog or digital model railway.
The Light-Interface is a high quality product that is supplied
within the assortment of Littfinski DatenTechnik (LDT).
We are wishing you having a good time using this product.
The finished module comes with a 24 month 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
damages caused by improper use or installation.
Connect the Light-Interface to the PC and
the Light-Display-Module:
• Attention: Before starting the installation switch off the
drive voltage by pushing the stop button or disconnect the
main supply.
• The Light-Display-Modules contain a large capacitor
which has to be completely discharged before the Light-
Display-Module can be connected or disconnected.
Please wait a couple of minutes after switching off the
supply transformer before you connect or disconnect the
Light-Display-Module.
The Light-Interface LI-LPT will be supplied together with a
connection cable for the parallel interface port (LPT) of the
computer.
Connect now the Light-Interface LI-LPT to the parallel
interface of your computer by using the 25-poles connection
cable. This port will be identified as printer-connection (LPT)
as well.

Part-No.:
The connection via an USB-Adapter is technically not possible.
On some few Laptops it can be possible that the parallel interface
will not comply to the actual valid standards. In this case
Light@Night cannot be used on this Laptop.
Connect now the Light-Interface via the 10-poles socket bar
BU1 either to a Light-Display- or a Light-Power-Module.
Attend in any case to the pin bars of the Light-Display-
respectively Light-Power-Module to make sure that there is no
offset to the socket bar of the Light-Interface.
For this issue please attend as well to the Operating
Instruction of the Light-Display- respectively Light-Power-
Module.

It is possible to connect up to 7 Light-Display- and/or Light-
Power-Modules to one Light-Interface. For this assembly shall
be the second Display-Module connected to the first Display-
Module via the 10-poles pin bar either directly or with the
extension cable "Kabel Light@Night xm".
The Light Interface receives always the operating voltage from
the first Light-Display- respectively Light-Power-Module. The
Light-Interface contains a galvanic separation to the parallel
interface of the PC. Therefore is no direct electrical connection
between model railway and computer existent.
One Light-Display-Module offers 40 light control outputs with
0.5 Ampere each. One Light-Power-Module offers 24 outputs
of 2.5 Ampere each. Each output can be individual configured via
the Light@Night PC-Software.
Further details referring to the wiring of lamps and light
emitting diodes are available within the Operating Instruction of
the Light-Display- respectively Light-Power-Module.
