868 SLH SYSTEM868 SLH SYSTEM
The 868 SLH Series is a patented 868 Mhz radio-control system with encrypted self-learning Rolling
Code. At every transmission, the transmitter code changes according to a complex algorithm,
synchronised with data awaited by the receiver.

868 SLH TRANSMITTERS
The transmitters (2/4 channel) can be of two types:
master
and
slave
.
How to recognise a master/slave transmitter
•
master
•
slave
: if you press any key of a master TX, the LED flashes before becoming steady.
: if you press any key of a slave TX, the LED goes on immediately with steady light.
Differences between master and slave TX
•
master
•
slave
: only a master TX can transfer its “system code” to decoding cards/RP receivers and to
other TXs (master or slave).
: unable to transfer its “system code” and, therefore, cannot be either duplicated, or used
for coding systems.
Can learn the “system code” from a master TX.

each channel).

Stores up to 1000 TXs.
OPERATION DESCRIPTION
The 868 SLH system is based on initial self-learning by the decoding card or RP receiver of a “system
code” received from a master TX.
The decoding card or RP receiver is able to store and recognise only TXs with the same “system
code” (albeit with a different serial code) : every TX (master or slave) must therefore learn the “system
code” from the master TX used for coding the decoding card/RP receiver.
The TX is stored on the decoding card/RP receiver by self-learning, at the second consecutive channel
activation.
Under normal operating conditions, the transmitter is immediately recognised by the decoding card/
RP receiver, providing 32 consecutive unsuccessful activation operations are not exceeded; above
this number, the transmitter's channel must be pressed twice in succession within a maximum of 5
seconds, in order to re-synchronise the system.
PROGRAMMING SEQUENCE
1) Power up the system after installing and connecting the
electrical components of the 868 SLH System (fig.1).
2) Use a master TX to set the “system code” on the decoding
card/RP receiver (see
3) Use the same master TX to set the system code on the system's
other TXs (See
4) Coded TXs are automatically stored in the decoding card/
RP receiver by simply activating the transmitter channel twice
in succession within 5 seconds.

SYSTEM CODING
•Simultaneously press push-buttons P1 and P2 of the master TX
and release them when the LED flashes (after about one
second);
•Press and hold down the learning button on the decoding
card/RP receiver: the LED must flash;
•While the master transmitter’s LED is flashing, press and hold
down a channel (the transmitter's LED goes on with steady
light);
•Before releasing the learning button on the decoding card/
RP receiver, check if the LED goes on with steady light for a
couple of seconds to confirm that the “system code” was saved.
•Release the button of the Master TX channel.

TX CODING
•Simultaneously press push-buttons P1 and P2 of the master TX used for
coding the system and release them when the LED flashes (after about
one second);
•Frontally bring into contact the master TX and the TX to be coded (master
or slave) as shown in figure 3;

•On the master TX (while its LED is flashing), press and
hold down the same channel used for coding the
system: the LED goes on with steady light;
•Press the required channel on the TX to be coded
and release it when the LED goes off after flashing
twice to confirm the “system code” was saved;
•Release the button of the Master TX channel;
•Repeat this procedure for every TX to be coded.
CONVERTING A TX FROM MASTER TO SLAVE
Procedure for converting a master transmitter into a slave
transmitter:
•Simultaneously press push-buttons P1 and P2 of the master TX and release them when the LED
flashes (after about one second);
•Again simultaneously press push-buttons P1 and P2 of the master TX and release them when the
LED flashes faster(after about one second);
•Press push-buttons P1-P2-P1 in sequence: the LED will flash twice before going off to confirm the
operation was performed.

RANDOMING THE SYSTEM CODE (master/slave TX)
“System codes” of all channels on a TX (master or slave) can be changed, by randomly generating
them with the following procedure:
•Simultaneously press push-buttons P1 and P2 of the master TX and release them when the LED
flashes (after about one second);
•Again simultaneously press push-buttons P1 and P2 of the master TX and release them when the
LED flashes faster(after about one second);
•Press push-buttons P1-P2 in sequence and then simultaneously (P1+P2): the LED will flash twice
before going off to confirm the operation was performed.
DELETING DECODER/MINIDEC/RP RECEIVER
Important: if this procedure is carried out, the "system code" and all stored serial codes for transmitters
will be deleted!
•Press and hold down the learning button on Decoder/Minidec/RP Receiver: the LED starts to flash;
•10 seconds later, the LED starts to flash more quickly;
•After another 10 seconds, the LED goes on with steady light for 5 seconds, and then goes off;
•When the LED goes off, release the learning button.
Note: If you release the push-button while the LED is flashing (slow or fast), deletion will not be
executed.
REPLACING THE BATTERY
If transmitter capacity drops, we recommend you to change the batteries. Procedure:
•Open the TX by unscrewing the screw at the rear;
•Replace the two mod. CR2032 3V lithium batteries, fitting them in the compartment and observing
correct polarity as shown in figure 4;
•Fit the base on the housing (ref. 1 fig. 4) before closing (ref.2 fig.4) and then secure with the screw
(ref.3 fig. 4).
