hints
1. Assembly (Skipping this can lead to troubles ! )
Ok, so we have your attention. These hints will help you to make this project successful. Read them carefully.
1.1 Make sure you have the right tools:
• A good quality soldering iron (25-40W) with a small tip.
• Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to the tip, to give it a wet look. This is called ‘thinning’ and
will protect the tip, and enables you to make good connections. When solder rolls off the tip, it needs cleaning.
• Thin raisin-core solder. Do not use any fl ux or grease.
• A diagonal cutter to trim excess wires. To avoid injury when cutting excess leads, hold the lead so they cannot
fl y towards the eyes.
• Needle nose pliers, for bending leads, or to hold components in place.
• Small blade and Phillips screwdrivers. A basic range is fi ne.

IV. SOFTWARE INSTALLATION
Step 2: open the fi le en select the software.
Step 4: Select the destination on your PC.
Remark: Software installation is not
mandatory , since the fi rst card that is
learned puts the unit into learnmode.
Once in learnmode, you can learn
more cards. See page 15

Step 6: Select additional tasks you would like
to be performed.
Step 7: Select “install” for installing the software. Step 8 : Click “fi nish” to exit setup.

Learning mode
Relay
When a valid card is presented the relay is energized.
The relay has three confi gurations (the confi guration is done via the PC):
• Toggle: swipe= ON, swipe= OFF.
• Momentary: ON while card is present.
• Timer/delayed: swipe= ON for n seconds.

An RFID tag sleeps in normal mode: it does not perform any activities and does not use any power.
This will change as soon as the tag moves through the reader’s fi eld. An RFID reader emits radio
waves at a frequency similar to those of the tag. The tag antenna retrieves enough energy
from these waves so as to exit the tag from the sleep mode and to power the microchip.
The tag’s microchip initiates a wireless communication with the reader (comparable to
what happens with a classic network) and receives a command. The chip will execute the
command, resulting in a data transfer through the tag’s antenna. In case of the passive tag in
the example, the data consists of the unique serial number of the tag in binary format (1’s and 0’s)
emitted as radio waves.
The antenna will pick up the data emission and sends it through a cable and in the form of electrical
signals to the reader’s control module. The module will in turn decode the radio signals and retrieve
VIII. HOW DOES AN RFID WORK?
CHIP with EPC code.
EPS, a set of numbers unique to the TAG.

How to Calculate the series resistor:
Example: operate a red led (1.7V) on a 9Vdc source.
Required led current for full brightness: 5mA (this can be found in the datasheet of the led)
Leds feature a specifi c voltage
drop, depending on type and
colour. Check the datasheet for
exact voltage drop and rated
current !
Never connect leds in parallel
