**5MHz RF
Link Kits - With Encoder and Decoder
1,
Transmitter module:
Frequency: **5MHz
Modulation: ASK
Working
Voltage: **9VDC
Frequency difference:
Min± *5kHz max± **0kHz
Launching power: *0mW(9V)
Working
current: <*0mA(9V)
Transmission rate:
&#x***4; *0Kbps
Encoder: PT***2
Timing resistor: 1.5M
Receiver Sensibility: ***5dBm
Emission
Distance: **0m in open ground
Size: *7 X *3
X 8mm
This module have been pinout All data
interface, convenient for useage, and only when more than one data
bits among *0 ~ *3 four data bits are high electricity level, the
module will transmit the high frequency signal.
2, Receiver module:
This is
superregeneration Decoder Receiver
Decoder:
PT***2
Size: *1X*4X6 mm
It can be compatible with transmitter with ***2 chip, **5MHz,
and 1.5M Timing resistor
Specialized
superheterodyne receiving module has an inherent
disadvantages:
When remote control signal is
too strong and the module oscillation signal will be blocked, and
unable to properly receive signal.
So at
this time, you should be away for some distance (such as *0 meters)
and then it can work normally.
In order to
test whether the receiving modules work normally, give a 5 V DC
voltag between the VCC and GND interface of receiving module, and
connect light emitting diode with pin *0, *1, *2, *3, *7 interface
respectively
When we press A of
trasmitter module, its corresponding pin *1 road LED will be light,
until press the other such as B key, pin *1 extinguish and
pin *2 will be light.
Pin *7 interface is
the effective decoding output port, no matter which of the
transmitter we push, it will become high level as long as decoding
successfully, the transmitter stop transmitting immediately and it
will extinguish
Warning: This kit is not
suitable for data transfer but remote control. Safe for 2
commands/second
3, Encoding and
Decoding:
The popular link is like this: MCU
-> Encoder -> Transmitter *****- Receiver ->
Decoder -> MCU
PT***2(Encoder) and
PT***2(Decoder) are optional, their existence is to 1)avoid
confusing when multiple RF links in range 2) isolate disturbance.
You can integrate the encoding and decoding work to the MCUs on
both side. Whenever there is no **5MHz devices around, you may use
it as direct cable connection.
