**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.
