CONNECTION DIAGRAM
The figure below shows the connection diagram. The exchange of the reader
with tags and relays is carried out over the radio channel. The reader is connected to the
monitoring device via 4 wires:the VCC output of the reader is connected to the battery,
the other three outputs of the reader are connected to the monitoring device. The
locking relay is powered from a 12 V source, which may not be associated with the
reader's power supply (there may be own power supply of any vehicle unit, for example,
the power supply circuit of a gasoline pump). The blocking relay is included in the
required blocking power circuit.
The reader works with a relay regardless of tags. Therefore, if necessary, the pack
can be organized both for working with tags only or for working only with relay.

WIRELESS LOCKING RELAY
The locking relay is receiving, waiting for radio commands from the reader. If the
relay is in the "locked" state, then the motion sensor is active and upon motion detection
the relay breaks the power circuit for a while. If the state is "unlocked", then the motion
sensor is inactive, and the power circuit is not broken. One of the advantages is that the
relay is controlled entirely by radio, there is no need to connect the relay to the general
power supply of the standard wiring to which the reader is connected.
RF TAGS
The tag communicates once a second. The tag has two operation modes:
programming and normal. Programming mode is used to register tags into the reader.
The programming mode is turned on for 1 second only when the tag is powered on
(battery is inserted), then the tag is switched on to normal operation mode, in which the
tag communicates with the reader once a second.
READER
When a registered tag is detected in the visibility zone, it sets a signal to the
presence output. On a command from the monitoring device, transmits to the relay a
command to block / unblock. The reader has two modes: normal mode and
programming mode. There is a special button on the reader board to enter the
programming mode.

4 OPERATION DESCRIPTION OF THE READER WITH
LOCKING RELAY
Each time the signal at the reader control input (lock / unlock) changes, a wireless
command is sent to lock / unlock the relay. If the relay is not in sight or the relay is not
energized, then the command from the reader is repeated for 15 seconds. On the other
hand, when the power is turned on, the relay independently requests the blocking status
from the reader for 15 seconds. If it was not possible to contact the reader (for example,
it was removed by the hijacker), then the relay automatically turns on the blocking.
In the event of a fall at the control input of the reader, a command to block is
sent, at a rising edge at the input, an unblock command is sent.
MOTION DETECTOR IN LOCKING RELAY
A motion sensor is implemented in the relay, which selects exactly the movement
of the car, does not respond to vibrations of a running engine (on a running engine, the
circuit will break precisely during movement). The sensor does not react to the wind
swinging the car, to blows on the body, to sound pops.
OРERATION DESCRIPTION OF THE RELAY
After turning on the relay requests the blocking status (BS) independently for 15
seconds. For the duration of these 15 seconds, the blocking status is taken from the non-
volatile memory, and if the previous status from the non-volatile memory was active,
then the motion control starts immediately 5 seconds after the relay is turned on. If the
previous blocking status from the non-volatile memory was inactive, then within 15
seconds while the status request is in progress, the movement is not controlled, the
circuit is normally closed. If there is no response from the reader within 15 seconds, the
relay automatically sets the active blocking status and motion control starts. When
power-up on the first successful exchange, it receives a blocking status, repeated
requests are not performed.
1. The relays can be installed in different circuits of the car, powered (12V) not
only from the ignition, but also from other circuits (for example, the power supply circuit
of a gasoline pump, or a circuit with a possible power interruption during motion). In
some devices, it happens that the power is regulated by an automatic control unit and
turns off during inactivity of the device. Usually, installers connect the relays to the
power of these devices and, therefore, the power to the relay may not appear
simultaneously with the ignition, including disappear periodically. When power is
applied, the relay must have an actual blocking status, therefore, when starting, the relay
requests the reader for the blocking status independently.
2. If the monitoring device and the reader are removed by the hijackers or are de-
energized, the relay, upon switching on (in most cases when the ignition appears), will

VEGA RK-2.4/User manual
10 Rev. № 01 of 21.08.2017
try to communicate with the reader for 15 seconds, if the reader does not respond, it will
automatically set the blocking status and start motion control.

5 RELAY AND TAGS REGISTRATION
ALERT SIGNALS OF THE READER
The following information signals are used for data transmission.
In programming mode:
1 impulse – 1 tag is registered in the reader
2 impulses – 2 tags are registered in the reader
3 impulses – 3 tags are registered in the reader
4 impulses – relay is registered in the reader
5 impulses – tag reader entered programming mode
In normal mode:
zero level (0 V) – tag has been detected
one level (12 V) – tag is absent
TAG REGISTRATION
Tags and relays are registering together in one programming mode.
When switching on, the tag makes a request for registering. If the registration of
the first tag was successful, the detector will signal this with one active impulse at the
presence output. If the registration of the second tag was successful, then two impulses
at the presence output, if the third registration was successful, then three impulses at the
presence output. All impulses go with a period of 1 second (duty cycle = 2), and their
number shows the number of tags already written into the reader.
Up to three marks can be entered into the system memory. Three memory cells
are used to store codes of three tags. The first registerable tag is stored in the 1st cell, the
second in the 2nd, the third in the 3rd. Before registering, it is necessary to remove the
batteries from the tags and remove other tags from the system identification zone.
To register the tags, it is necessary to put the reader into the programming mode
(hold the button for 5 seconds and wait until 5 pulses appear at the presence output). To
remain the reader in the programming mode, you must constantly hold the button
down. If the button is released and no longer pressed, the reader will exit programming
mode after 12 seconds. Pressing the button in programming mode prolongs
programming mode by 12 seconds. It is necessary to insert the battery into the tag
which needed to be registered. When try to write the fourth tag, the first will be

VEGA RK-2.4/User manual
12 Rev. № 01 of 21.08.2017
overwritten, and the fourth tag will be entered into the first memory cell. An attempt to
re-register a mark already registered in the current session will not lead to deletion of
other marks, the tag will be overwritten in the cell where it was already registered.
If at least one new tag is registered into the system (after entering the
programming mode, i.e., in a new programming cycle), then all codes of previously
registered tags are automatically overwritten (protection against programming foreign
tags, for example, in a service center). Therefore, in each new programming session, all
tags that are supposed to be used must be re-written into the system. If the system was
in programming mode, but no new tags was registered (there was an automatic or
forced exit from the programming mode), then all old tags remain valid.
RELAY REGISTRATION
The wireless relay, like the tags, must be registered in the system. A new relay
received from the factory is "nulled" (without registration). Only a nulled relay can be
registered. How to reset the relay is described in the section below ««Nulling» of the
relay». When turned on, the "nulled relay" is registered into the reader. If more than one
relay is registering, then it is advisable to register each relay separately for making sure
that each relay is registered.
To register switch the reader into the programming mode (hold the button for 5
seconds, in the same way as for the tags; the relay can be registered together with the
tags). Next, apply power to the assigned nulled relay, if the relay is registered, then 4
impulses will appear at the presence output. Then apply power to the next nulled relay,
successful registration will also be signaled by the reader with four impulses at the
presence output. Without exiting the programming mode, you can immediately register
the tags, but it should be remembered that registering at least one tag will lead to the
deletion of old tags from memory.
When registering new relays, the old ones are not deleted, but are
written to the next memory cell (maximum 5 cells)
If all five cells are filled, then the sixth relay will not be registered. During normal
operation, the reader requests all the relays written in the memory cells. If during normal
operation the relay could not be contacted 50 times, then the cell of this relay is marked
as deleted, but the relay remains in memory, the reader waits for the possibility of its
appearance in the system. But after entering the programming mode and register at least
one relay, then all relays marked as deleted will be overwritten. In their cells can be
overwritten by new relays.
After releasing the button, the reader will exit the programming mode after 12
seconds.

«NULLING» OF THE RELAY
To reset an already registered relay, it is necessary to reverse its polarity. Reverse
polarity of the power supply means + 12V to the black wire and ground to the red wire.
The relay will start, reset its registration, and click the key 3 times. Nulled relay can be
registered again, if the relay is not nulled, then it does not make registering requests at
startup.
When connecting the relay, it is necessary to observe the polarity
(red + 12V, black - ground). Otherwise, the relay will be deleted, and
you will need to register the relay.
