SVS CX12 R Bedienungsanleitung Seite 6

1 Mode of Operation
The receiver module CX-12 R detects serial data from the corresponding transmitter, e.g. switching signals (ON/OFF states), and
transmits back to the transmitter an acknowledgement with additional information.
It is forbidden to modify or change component parts of the product !
The electronic components are not protected against weather conditions. Therefore, it should not be used in the exterior without taking
necessary precautions. The cable connections should not be longer than 1 m.
It should be noted that for applications that could put human life at risk, by using radio connection there is always
present a potential hazard due to extraneous disturbances.
The Operating Instructions need to be followed at all times.
2 Range of operation
The system is designed for large operating range up to 1000 meters and even obstructing walls or steel reinforced constructions can
be penetrated.
The range may be reduced for the following reasons:
• Buildings, vegetation or any other objects will substantially reduce the operating range.
• The distance between the antenna and the human body or other conducting objects (e.g. Earth) may influence the working range.
• "Background electrical noise" could be relatively high so that the signal-to-noise-ratio decreases and therewith the range. Also other
devices, with similar operating frequency, located within the neighbourhood may disturb the receiver.
• Operating the receiver next to inadequately shielded electronic boards or other devices (e.g. PC's) that produce electromagnetic
radiation, can substantially reduce the range of operation and could result in an apparent intermittent operation.
It is forbidden to modify, change or manipulate component parts of the product!
3 Description
CX12 R receives and demodulates the transmitter signal and forwards it to the 4 digital and 1 analogue outputs. Transmitter signals are
only accepted when the address matches with a previously learned one.
Furthermore 2 outputs may control LED´s to show to the user functionality and status of the transmitters battery.
As long as valid data are received the corresponding outputs remain activated. Incoming OFF-signals deactivate immediately the
assigned output. Due to distortions it may occur in rare cases that the receiver do not understand the OFF-signal. In this case outputs
will be switched off after a delay of about 1.5 s.
CX-12 R may learn up to 60 different transmitter
addresses. Each received and valid data package will
be confirmed to the transmitter with additional information.
In order to obtain a maximum of safety you may change
over to a second working frequency if the first frequency
channel is disturbed by another radio service.
After received data or power-on CX-12 R keeps
continuous working for a period of 10 minutes. Then.
In order to save energy, a clocked operation starts.
That is why the next reception may be retarded up to 2 s.
If this delay is undesirable the clocked operation may be
disabled (Pin1).
Pin Description:
1 Input for selection of automatic clocked operation or continuous working
open or +U:
GND:
2 Input to activate the Learn- or Erase mode
open or +U:
GND, short(<1s):
GND for more than 5s:
3 Output to control a LED (low active)
reception of data:
Learn mode is activated::
Erase mode:
4 Output D4:
5 Output D3:
6 Analogue Value Output
clocked operation starts 10 minutes after power on or the last received data package
receiver is set to continuous work
normal receive mode
CX-12 R expects a valid transmitter address; Learn mode is stopped automatically after 30s
CX-12 R deletes all previously learned addresses
flashes for each data package received
LED remains on until an address is learned and starts flashing
LED remains on until 5s later it starts flashing (all stored transmitter addresses are deleted.
Digital output (high active) goes high with the ON information of the transmitter and switches to
low immediately after reception of the OFF information. In case of missing OFF information while
no more data are received the output remains at high level for another 1.5s (delay)
same as output D4 (Pin4)
of the received analogue value from the transmitter (value between +U and GND, Ri=56 kOhm)
