Thank you for choosing a this 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- FACTORY SETTINGS
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 CLOCK and DATA.
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 formatted signal is carried out from the receiver unless a
memorization procedure is performed.
Follow the procedure below to memorize the transmitter codes into the
memory receiver.
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.
5- VISUALISATION
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 can’t accept
any transmitter code, as a new product.

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 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 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 L2 turns on and then release it.
2) Push simultaneously 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 memory, memorization of
already stored codes ) causes a 2 quick flashes of led L2. The guarantee period of this product is 24 months, beginning from the
manufacturer date. During this period, if the product does not work correctly, due
to a defective component, the product will be repaired or substituted at the
discretion of the producer. The guarantee does not cover the plastic container
integrity. After-sale service is supplied at the producer's factory.

1) Keep the button P1 pressed down until 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 kept.
The message is composed by 65 bits, divided into 14 groups of 5 bits.
The first bit carried out is the bit LSB of each group.
Each group is composed by the BCD number, corresponding to the
decimal digit, with the odd parity joined at the end.
Example: Decimal digit 7 : --> BCD : 0111 --> Inversion : 1110 -->
Odd parity : 0 --> String in output : 11100.
The parity bit is the last to be carried out.
Message example: transmission of the decimal serial number “10” of
the transmitter, acting on the key B.
The 8th packet becomes 0000 + 0001 = 0001 --> swap 1000
+ odd parity = 10000
The group identification is the following:
LEADING ZERO = “00000”
START SENTINEL = “11010”: equivalent to hexadecimal “B” completed
with the odd parity bit and sent out beginning from the (LSB).
END SENTINEL = “11111”: équivalent to hexadecimal “F” with the odd
parity bit.
LRC (Longitudinal Redundancy Check) “CCCCP” = In this case the letters
“C” are the result of the XOR of all the data and the two SENTINEL,
calculated bit by bit, and P represent the odd parity calculated over the 4
bits.
TRAILING ZERO = “00000”
DATA: 8 packets of 5 bits which represent the serial number of the
transmitter, in BCD format. Each packet includes 4 bits + odd parity and
is transmitted beginning from the bit MSB.
TRANSMITTER KEY: The transmitter key activated is codified as follows:
A = “0”; B = “1”; C = “2”; D = “3”; A+D = “4”; B+C = “5”;
C+D = “6”;
The decimal number is addictioned to the eighth packet
The combination A+B = “F” isn’t allowed.
