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.
