1A - Description
The receiver is a superheterodyne
receiver operating at the frequency 433,92 MHz.
It is composed by a main board in which there are the
power
supply output connectors and by a RF card.
The two outputs have an open drain configuration with
output
signal in “Wiegand 26 bit format”.
The appliance is housed in an indoor container.

Thank you for choosing a RCS product. You are
recommended to
read this manual carefully before installing the
product.

CONTENTS
The receiver allocation is very important for the best
operation of the system.
Place the receiver far from interference sources such as
big magnetic fields or radio emissions.
The installation and the positioning of the antenna is
very important as well. Before to install the antenna it
is
advisable to make some tests on the site.
Use shielded cable type RG58 ( impedance 50 Ohm ) for
the antenna connection.

2- TRANSMITTER MEMORIZATION
A short flash of L2 indicates a correct received word
but not
approved : that means that the facility code or the
transmitter code received is wrong.
A flash of 1 second of L2 indicates that a correct
signal has
been received and that the correct frame in wiegand
format
has been sent from the outputs DATA0 and DATA1.
The information contained in the frame sent by the
transmitter
is composed by a FACILITY CODE , a KEY CODE and by a
SERIAL
NUMBER.
The set-in-factory receiver doesn’t accept any code.
That means that no wiegand formatted signal is carried
out
from the receiver unless a memorization procedure is
performed.
Follow the procedure below to memorize the transmitter
codes
4- FACILITY CODE CHECK DISABLING
It is possible to disable the check performed by the
receiver
on the facility code of the received signal.
At the end of the following procedure, the receiver
accepts
any facility code and maintains the check on the key
code.
This new configuration of the receiver is temporary and
can
be restored by carrying on the same procedure.
1) Keep the button P1 pressed down until the led L2
turns on
and then release it.
2) Within 1 sec. press again P1.
At this point the led L2 start to flash quickly and so
the receiver can accept any facility code.
Repeat the phases 1 and 2 to cancel the operation and to
recover the initial state.
If a power failure occurs after the phase2 the new
configuration is mantained.
5- VISUALIZATION
6- MEMORY ERASURE
This procedure allows to erase the memory of the
receiver.
1) Keep button P1 pressed down until L2 turns on.
2) Release P1 and then press it again until L2 start to
flash 3
times.
At this point the settings stored are cancelled, and the
receiver

Before commencing the procedure make sure that the power
led L1 is ON.
The EEPROM of the receiver is capable to store up to 50
different combinations: “facility code - Key code”.
The key codes of each transmitter can be A, B,A+B, where
A+B
is the code sent at the pressure of both the keys at the
same
time.
Combinations of this type can be, for example:
002 - A, 002 - B, 002 - (A+B), 003 - B, 010 - (A+B), and
so on.
PART 1: transmitter key A programming
1) Keep the button P1 pressed down until the led L2
turns on
and then release it.
2) Press the key A of the transmitter which has to be
memorized.
3) The led L2 turns off and then make a short flash.
PART 2: transmitter key B programming
1) Keep the button P1 pressed down until the led L2
turns on
and then release it.
2) Press the key B of the transmitter which has to be
memorized.
3) The led L2 turns off and then make a short flash.
PART 3: transmitter key A+B programming
1) Keep the button P1 pressed down until the led L2
turns on
and then release it.
2) Press at the same time the keys A and B of the
transmitter
which has to be memorized.
3) The led L2 turns off and then make a short flash.
If, for any reason, the memorization procedure hasn’t
been
successfully, the led L2 doesn’t make the final flash.
Any operation not allowed ( memorization with full

Any changes or modifications on RCS equipment not
expressly
approved by RCS could void the user’s authority to
operate with
the equipment.
