OPERATION GUIDE
General description
*The CDP-02N models are hereinafter referred to as CDP-02N (for transmitters and
receivers), CDP-TX-02N (for transmitters) and CDP-RX-02N (for receivers), unless
otherwise stated.
The CDP-02N is suitable for various application fields such as wireless data communication,
remote control, telemetry or wireless security systems. It is easy to use and integrate into
application systems.
The CDP-02N is equipped with a frequency synthesizer system with micro controller.
Available frequency ranges are from 433.875 MHz to 434.650 MHz (32 channels:16 ch x 2
groups) and from 458.525 MHz to 458.775 MHz (11 channels). The compact size, low
operating voltage and frequency selectability of the CDP-02N make it ideal for various
applications where its interference rejection and practical distance range is far better than
similar RF modules based on wide band SAW-resonator frequency generators.
Serial digital data (TTL level), such as pulse width modulation signals and signals from
standard encoder-decoder circuits of the given AF bandwidth, can be transmitted.
CDP-TX-02N transmitter module
The CDP-TX-02N is a UHF FM-narrow band transmitter with PLL synthesizer and micro
controller for high frequency stability and channel selectability. Modern SMT technology gives
it its small size - much smaller than a match box.
The narrow band FM modulation (direct FSK) enables efficient use of the available RF
spectrum. Different modules can operate in a 25 KHz channel spacing scheme unlike SAW
resonator transmitters which use a very broad band of the frequency spectrum.
The CDP-TX-02N can transmit any 5 V digital input data in the specified frequency range.
Analog data is digitized by the internal comparator.
In about 80 msec (90 msec for 458 MHz) after the transmitter is connected to a power source,
PLL is locked and data can be transmitted without further control or synchronization.
Transmission is physically achieved by a flexible Lambda/4 antenna connected to the module.
The amount of radiated power and the surrounding of the antenna influences directional
behavior. Installation in a bigger metal housing with a ground connected to the transmitter
module housing and the transmitter antenna placed in an upright position outside the metal
housing will reduce the antenna impedance and increase the radiated power. For best
performance in a user system general rules of radio frequency technology should be taken
into consideration.
The same considerations should also be applied to the receiver.

OPERATION GUIDE
Data format
The digital data fed to the transmitter is passed through an internal low-pass filter to limit the
bandwidth of the digital data. This is needed for an efficient use of the available RF spectrum.
At the receiver, a band-pass filter is used to reject noise and out-of-band signals in the
received signal. Together the transmittable signal bandwidth is approximately 150 Hz to 2400
Hz. At the receiver, the signal is converted back into a digital signal for compatibility with
succeeding digital systems. The type of digital data signals transmittable is limited by the
bandwidth of the system.
DC signal or long intervals of HIGH or LOW bits should be avoided. Succeeding bits can be
distorted in their bit length. If the sequence of HIGH or LOW bits is too long it is possible that
the logic level of the data output will be changed.
The best countermeasure is to use a digital encoding scheme, which guarantees that no low
frequency components are included in the data signal. This can be achieved, for example,
with "Manchester" encoding. A digital 1 is coded in a sequence of 10 and a digital 0 is
encoded into a sequence of 01. In most cases it is also sufficient to transmit serial data by
using start and stop bits of different logical level as can be done with the RS232 format. Each
transmitted byte will be preceded by a 0 bit and succeeded by a 1 bit.
The CDP-02N was tested with a number of standard encoder-decoder IC's for simple remote
control. There should be no problem with data speeds in the 300 to 4800 Baud range .
Because of the wide variety of data formats, data speeds and digital modulation techniques, it
is best to set-up a 'worst case' scenario and test the data transmission before the CDP-02N
is used in a practical application.
Further advice can be given if the precise format of the data and system requirement is notified to the dealer or
directly to Circuit Design, Inc. Your inquiries and comments are welcome and will also help other users.
Channel and Frequency Setting
CDP-TX/RX-02(A)N (Dip switch type)
By use of a chip mounted 4-bit switch and a jumper on the PCB, 32 channels can be easily
selected. In the 434 MHz version, the 32 channels are divided to 2 groups: group A and
group B. Each group of channels can be selected by soldering the jumper ON or OFF. When
the jumper is ON, group A is selected. When the jumper is OFF, group B is selected. There
are 16 channels in each group and they can easily be selected using the 4-bit switch. Before
shipment all the modules are set to group B and all the 4 bits of the switch are set to OFF.
(434.65 MHz)
For 458 MHz, all the 11 channels can easily be selected using the 4-bit switch on PCB.
Please refer to CHANNEL AND FREQUENCY SETTINGS for information on channel
selection.
CDP-TX/RX-02(A)NP (Pin connector type)
By use of 8-pin connectors, channel setting can be performed externally.
The channel table is the same as the dip switch type. For information on channel setting,
please refer to CHANNEL AND FREQUENCY SETTINGS in this document.
Notice: Turn off the power of the module when setting the frequency channel of the transmitters (CDP-TX-
02(A)N and CDP-TX-02(A)NP). The status of each channel port will be read by the CPU when power is
turned on. It is not possible to change the channel setting while the power is on.
For the receiver modules (CDP-RX-02(A)N and CDP-RX-02(A)NP), frequency setting and channel change
can be performed with the power turned on.
