LDT 050602 Light-Interface for the PC-Light Control
Operating Instructions
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.
- Also, note that electronic semiconductors are very sensitive to electrostatic discharges and can be destroyed by them. Therefore, discharge yourself before touching the modules on a grounded metal surface (e.g. heater, water pipe or protective earth connection) or work on a grounded electrostatic protection mat or with a wrist strap for electrostatic protection.
- We designed our devices for indoor use only.
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.
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.
Installation
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.
Colored sample connections for the wiring can be additionally found on our web
site www.ldt-infocenter.com at the section “Sample Connections”.
Installation of Light@Night demonstration software
The PC-Software Light@Night can be used in connection with the Interface LI-
LPT on every PC with a Windows 32-Bit operation system.
Windows 32-bit Operating system| Windows 95, 98, Me, NT,
2000, XP, Vista, Win 7, Win 8
/ 8.1, Win 10
---|---
CPU| Intel or AMD from 300MHz clock frequency
Working memory| 64Mbyte RAM
Interface to the Light- Interface| Printer connection port (LPT)
Together with the Light-Interface LI-LPT you received a CD-ROM containing the
Light@Night PC-demonstration software.
This demo-software enables you to test the Light@Night hardware without the
complete version. There is a substantial difference to the complete software
version. The light outputs of the demo-version offers only light effects for
“Glühbirne” (incandescent lamps) and “Blinklicht” (flashing lights).
The complete version of the Light@Night PC-software for all light effects
(neon lights, gas street lamps, flashing blue lights, light chains, traffic
lights and many others) including a manual (in German language only) is
available by company Railware (https://railware.de).
For the installation of the demo-software please insert the supplied CD-ROM
into the CD-ROM drive of your computer:
- The installation program will start automatically. In case the function “auto start” has been set to “off” on your PC please start the program “Execute…” at the Windows start menu and enter the following line (without sign): ´d:\setup.exe´. Please replace the letter
dwith the letter-code of your CD-ROM drive. - Follow now the instructions of the installation program.
- Enter the directory where Light@Night shall be installed. Recommendation: ´C:\Program\LightATNight´.
- The following installation will run automatically.
- Finally please restart your PC.
For your first trials you can find a complete sample of the Light-Display-
Module on the screen after the restart of LightAtNight.
As first step please check if the correct parallel interface has been set at
the PC-software for the Light-Interface LI-LPT.
Therefore please click at the menu bar on “Options” and on “Interface”. The
window “Interface Hardware” will turn up. You can select now the parallel
interface between LPT1 and LPT4 under which port you have connected the Light-
Interface LI-LPT.
Before you are switching-on the transformer for the supply of the Light-
Display-Module you have to connect an incandescent lamp or a LED with serial
resistor to the output 2 of the Light-Display.
Further information for the wiring of incandescent lamps and light emitting
diodes can be found within the operating instruction of the Light-Display-
respectively Light-Power-Module.
Now switch-on the transformer for the supply of the Light-Display-Module and
click at the menu bar on “Start“. The model incandescent lamp respectively the
LED connected to output 2 will flash now continuously. By clicking on “Stop”
the flashing will stop and you will be again at the entry mode of the PC-demo-
software.
To get use to the extensive possibilities of the Light@Night PC-Software the
software offers detailed help files. You can call the help file with “F1” and
read the paragraph “Operating the Software” and “Configuration”.
The complete version of the PC-software will be supplied with a manual which
describes all light effects and possibilities for the PC-light control
Light@Night in detail. From our Web-Site at the section “Downloads” you
download the manual.
Accessories
For the assembly of the Light@Night hardware we offer suitable assembly material under the order coder “MON-SET”. A set consist of 4 plastic distance washer and 4 matching wood screws. Under the order code “Kabel Light@Night xm” you can order an extension cable for the Light-Display- and Light-Power-Module for a possible assembly of the modules at a 0.5m, 1m or 2 meter distance.
