Interface s88
TD-88
TD-88-B
Part-No.:
060021
>> kit (-B)<<
The
Interface TD-88
is suitable for the
s88-Feedback
Bus.
It is able to manage up to
31 Transponder-Readers
COL-10
and feeds the
transponder data
into the
s88-
Feedback Bus
.
The
transponder data
will be transmitted via the
High
Speed Interfaces HSI-88
respectively via the
HSI-88-
USB
to the
PC
.
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:
You have purchased the s88-interface
TD-88
as a kit supplied
within the assortment of

•
These kits are of high quality and easy to assemble.
We are wishing you having a good time for assembling and
application of this product!
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
•
We designed our devices for indoor use only.
•
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 a heat 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 possibly be 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.
With reason to different makes of
electrolytic capacitors
you
will find different markings of the polarity. Some are marked with
"+" and some are marked with "-". Each capacitor has to be
assembled to the board that the marking on the capacitor is in
correspondence with the marking on the pc-board.
For
tantalum capacitors
please attend to the
connection wire
marked "+". This wire has to correspond to the printed mark on
the pc-board.
The flattened side of the
transistors
has to be observed.
Light emitting diodes
have to be assembled that the long wire
of the diode corresponds to the mark "+" on the pc-board. Before
assembly please slip the
distance spacer
onto the connection
wires.
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
IC`s
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.
