instruction carefully.
Introduction:
You have purchased the 8 fold feedback module SX-GB-8 with
integrated detection of track occupancy for your model railway.
The SX-GB-8 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.
Feedback modules SX-GB-8 of the
Series
can be operated with your digital model railway without
any problems.
The SX-GB-8 is suitable for all Selectrix® or compatible
digital central units which support the Sx-bus by using the
5-poles diode-plug.
General:
Tools required for the assembly
Please assure that the following tools are available:
• a small side cutter
• a mini soldering iron with a small tip
• solder tin (if possible 0,5mm diameter)
Safety Instructions
• All electrical and electronic components included in this kit
shall be used on low voltage only by using a tested and
approved voltage transducer (transformer). All components
are sensitive to heat. During soldering the heat shall be
applied for a very short period only.
• The soldering iron develops up to 400°C. Please keep
continual attention to this tool. Keep sufficient distance to
combustible material. Use a heat resistant pad for this work.
• This kit consist of small parts, which can be possibly
swallowed from children. Children (especially under 3 years)
shall not participate on the assembly without supervision.

Set-Up:
For the board assembly please follow exact the sequence of
the below assembly list. Cross each line off as done after
completing the insertion and the soldering of the respective
part.
For the diodes please keep special attention to the correct
polarity (marked line for the cathode).
The connector of tantalum capacitors marked with "+" has to
correspond with the respective marking on the pc-board.
Integrated circuits (IC`s) are either marked with a half round
notch on one end or a printed point for the correct mounting
position. Push the IC`s into the correct socket assuring that the
notch or the printed point is corresponding to the half-rounded
marking on the pc-board.
Please attend to the sensitivity of the ICs to electrostatic
discharge, which will cause immediate damage of the IC.
Before touching those components please discharge yourself
by contacting an earthed metal (for example: an earthed
radiator) or work with an electrostatic safety pad.
On transistors and voltage-regulators it has to be attended
to the flattened side.
The position of the soldered wire-bridge is marked on the
board with a thick white line between the respective bores.
Before assembling the clamps please connect the two 2-pole
and the two 3-pole clamps together to a block with 10
connections.
The light emitting diodes have to be assembled on the pc-
board with the longer leg to be connected to "+". Before
soldering the diodes push the distance spacers onto the legs.
