RE-DTX-K2D
Digital transmitter and receiver
Product description
RE-DTX-K2D transmitters and receivers are used to radio
the audio / video signal of an analog wired camera and
adopt digital technology that allows total immunity to
interference. The incoming analog video signal is digitally
encoded in the transmitter and sent via radio with FHSS
modulation and encrypted coding to prevent
unauthorized reception. In the receiver, the signal is
converted back to analog in order to connect TVs,
monitors or video recorders.
Composition of the product
The product includes:
Transmitter to be connected to the analog camera
and receiver to be connected to an AHD monitor or
DVR. ATTENTION: To see the output image from the
receiver you need a DVR or monitor capable of
supporting AHD 1080P.
Adapter cables with RCA male video connector
(yellow) for connecting the RX to the monitor or the
TX to the camera.
Omnidirectional antennas.
Video signal supported
RE-DTX-K2D transmitters support AHD, CVI or TVI analog
video signal in 720P or 1080P resolution.
Installation and wiring
On the back of the modules there are two cables for
connecting a 12-42VDC power input to be connected to a
power supply or battery.
In the TX the end of the video cable will be
connected to the camera. In the RX the end of the video
cable will be connected to the AHD monitor or DVR.
The connectors are of the male RCA type (1xVideo). If
the device to be connected has a BNC connector, which
is very common in CCTV, a RE-BNCRCA1 adapter is
required.
Both the transmitter and receiver have two DC power
plugs. Connect the DC power to the BLACK plug. With the
red plug you can possibly supply power to the camera or
DVR.
The antennas screw onto the SMA connectors. The
antenna is omnidirectional and does not need to be
oriented.
Power the transmitter and receiver using 12VDC 1A
power supplies (not included) or by connecting them to
the vehicle battery, when installing on vehicles
The containers are IP67 watertight and shockproof.
First ignition
Once the power supply is connected, the red POWER LED
lights up on both devices. Immediately afterwards, the
green PAIRING LED lights up when the two devices are
paired and ready for image transmission. Transmitter
and receiver are supplied already coupled from the
factory so no operation is required for them to connect
together. If the LINK LEDs do not light up, it means that
the two modules are unable to communicate with each
other, presumably because they are placed too far away
or due to the presence of too many obstacles between
the antennas.
Pairing Button (PAIR)
TX and RX communicate with each other in a coded way
so they must be coupled together to function correctly.
However, the PAIR button present on TX and RX as a rule
must not be used as the two devices are already
delivered coupled to each other at the factory.
If for maintenance reasons it should be necessary to re-
couple TX and RX, proceed as follows
Power TX and RX by placing them at a short
distance.
Press the PAIR button either on the transmitter or on
the receiver and hold it down until the green PAIRING
LED starts flashing quickly. Then release the PAIR
button.
Carry out the same operation on the other module to
be coupled
Wait for the TX-RX pairing to complete without
turning off the equipment.
At the end of the procedure, the two green LINK
LEDs will turn on steadily
Each transmitter can be paired with only one
receiver.
The range of transmission
RE-DTX-K2D allow a range in free air of about 300 m.
The flow rate value is given in free air, as the presence of
obstacles, such as walls or other, drastically reduces the
flow rate, but in a very variable way.
Tips
Place the transmitter and receiver in a position as
detected as possible.
Position the camera so that on the imaginary line
joining the 2 antennas there are as few obstacles as
possible.
In particular, try to avoid the presence of obstacles very
close to the transmitter.
Avoid the interposition of metal obstacles (eg metal
doors etc.) as they are highly shielding.
