1. General information
LEX868 receiver belongs to the group of radio remote control devices where the complimentary protocol with
the IRS 104 bit encryption is used for the communication. In the series of devices marked DTM868MHz, additionally a
frequency of a radio signal of 868 MHz was applied. This solution increases the reliability of the range in places with high-
intensity of noises and in bigger centres of devices working in commonly used 433MHz frequency. SK modulation applied
along with the intelligent algorithm of the adaptation of radio circumferences of the transmitter and the receiver ensures
even better noise immunity. Solutions used are a guarantor of the noticeable lack of worsening radio parameters
associated with interferences of mobile phones and GSM base transceiver stations.
LEX868 receiver (fig.1) is a 2/4 channel device intended for the cooperation with elements of gate and building
automation. Thanks to the LEX868 receiver it is possible to extend the functionality of gate and other automation
installations for the function of remote control in the simplest manner. Different possible modes of output channels give
huge flexibility and allow to adjust to the conditions of the majority of installations. The receiver cooperates with remotes
of DTM868MHz series.
This receiver is the improved version of the MAX receiver. Strong emphasis was put for improving the
functionality through the following:
remote control using the integration in so called Cloud – optional WL module necessary;
possibility to register the events in the off-line mode;
increasing the memory of the remotes;
adding the Galactic function, which enables adding remotes programmed outside the installation;
adding an information input enabling the control of the gate state;adding manual control output with the
possibility to assign it to any output channels;
enlarging the display to 4 digits –for easier menu operation;
possibility to extend for 2 additional channels thanks to optional modules, load capacity from 1A or to 5A;
possibility to upgrade the programme of the receiver – optional WL module necessary;
usage of dedicated casing and possibilities of the installation with the use of distance pegs – e.g. in the casing of
alarm switchboard.
Thanks to these changes it is currently the most advanced and expanded receiver in the offer of DTM System.

3. Installation and operating mode
The receiver is delivered in the dedicated surface casing IP-54 tightness with the set of rubber glands (it is
possible to apply screwed ø16mm glands). It is also possible to install the receiver directly in the casing of other device. or
that purpose the board of the receiver has four assembly holes of the standard span. In this case distance pegs should be
used (accessible as Option at the producer). At the site chosen for the installation, in order to achieve the optimum radio
range, it is important to remember about:
negative influence of electrical devices and metal elements in the neighbourhood of the receiver aerial ;
negative influence of radio noise from other sources than the remote;
negative influence of buildings, wet or reinforced concrete walls;
shorter range with used battery of the remote;
increased range with the higher location of the receiver aerial.
The receiver has screw clamp terminals for connecting to the wiring of steered automation ( ig.2). Power cords
must be connected to clamps "+" and "-". Controlled devices should be connected to receiver outputs OUT1 and OUT2
and the button of the manual control to clamps A and B of the receiver.
A flexible rod aerial is connected to the aerial adaptor in the brand new receiver. In order to increase the range of
the radio remote control it is possible to use the outside aerial with the use of a coaxial cable with the impedance 50Ω. The
aerial coaxial cable should be connected to the clamp marked (centre vein of the cable) and to the clamp marked
(screen of the cable to mass of the arrangement). Optional it is possible to use the outside aerial fixed to the casing of the
receiver.
Fig. 2 View of the base board of the receiver with the description of extractions and main functional elements.
Connecting the power supply is indicated with lighting of the green POWER diode. While the device is working
every activation of the C1/C2 output channel is signalled with switching on the C1/C2 diode . In the non active state the
display is put out. At the triggering of receiver with radio transmitter (remote control), the number of the pressed remote
button and its reference number appears on the display ( ig.3). In the case of triggering manual control output, an
announcement 'Sr' appears. In case of some failures of the device the error codes appear on the display (see pt 10).
Stopping of the receiver caused by performing internal operations e.g. formatting the memory of the receiver, is signalled
with characteristic animation of wave on the display.
The INPUT input (screw terminals A and B) can work in one of two modes: manual control mode or status
signaling mode. Depending on the setting, a momentary button or a sensor with a potential-free NO or NC type output
should be connected to terminals A and B.

All works associated with connecting, installing and removing additional modules should be performed with
disconnected power supply of the LEX868 receiver.

4.1. Fast assigning of the remote button to the channel of the receiver
To make work with the LEX868 receiver easier fast assigning of the remote button to the channel of the receiver
was introduced. With the use of C1/C2 button it is possible to assign the remote to the C1/C2 channel. This activity requires
pressing and holding the button of C1/C2 channel for more than 5 sec (accordingly ‘c1’ and ‘c2’ are shown on the display)
and pressing chosen button of the remote at this time ( ig.4).
The individual blockade of simple/remote assigning of the remote is switched off after the assigning.
Fig. 4 The example of assigning button number 1 to the channel C1 of the receiver with the help of C1 buttons.
In the receiver equipped in optional REL-2/REL-2-PWR module assigning/removing the remote to the channels
C3/C4 is made similarly as for the channels C1/C2.
4.2. Fast removing of the connection bet een the remote button and the channel of the receiver
To remove the connection between the remote button and C1 channel it is necessary to:
press and hold C1 button for more than 5 sec;
'c1’ is shown on the display;
press the removed remote button;
the connection between the remote and the channel is deleted.
Removing the remote button from the other channel of the receiver is made similarly as for the channel C1.
In the case of removing all connections of remote buttons and the channels of the receiver the remote is in the
memory of the receiver on the set position all the time. To remove the remote from the receiver memory it is
necessary to use UP function from the submenu of PP function (see pt.5.1.7).
4.3. Remote assigning of the remote in the radio range of the receiver
This function allows to assign new remotes without the necessity of physical access to the receiver button. The
condition of success is to be in the radio range of the
receiver and to have remote assigned earlier. To assign
the remote to the receiver memory it is necessary to:
press and hold for about 15sec any button of
the remote assigned earlier;
in time no longer that 3 sec from releasing the
remote button press and hold for about 15 sec
any button on the remote which is to be
assigned.
Fig

ailed assigning of the remote can be caused by:
low battery of any of the remotes;
radio noise which could appear during the process of remote assigning;
full memory of the receiver (attempt to assign 10.000
th
remote);
different types of remotes used.
The remote after assigning inherits the settings of the old remote which took part in the assigning process. If the
remote with admin function switched on was used then individual blockade of remote assigning is automatically switched
on in the new remote.
4.4. Adding a remote control ith the Galactic function
The Galactic function allows for remote adding of remotes programmed outside the installation, without the
need for physical access to the receiver buttons. The condition for successful adding is to have a remote with the Galactic
function, with an authentication code set, consistent with the code set in the receiver.
To add a remote control with the Galactic
function, being within the radio range of the receiver:
press and hold any two buttons on the
remote control for 5 seconds
activate the remote control in the system
by pressing any button
The added remote control works immediately in
accordance with the programmed settings.
Unsuccessful adding of the remote control may be caused by:
incompatibility of the authentication codes of the receiver and the transmitter;
radio interference that may have occurred during the procedure;
the receiver's memory is full (attempt to enter 10.000 remote control);
low battery of the remote control.
