Low power transmission with 2W,High Receiver sensitivity -123dbm(1200bps);-118dbm(9600bps),
Small size 80mm×45mm×20mm (Without Antenna connector)
2.With 433MHz as factory default carrier frequency, 400~470MHz ISM frequency is available if needed.
3.High anti- interference and Low BER (Bit error Rate)
Based on the Gaussian Frequency Shift Keying (FSK/GFSK) modulation, the high-efficiency forward error correction
channel encoding technology is used to enhance data’s resistance to both transient interference and random interference and
the actual bit error rate of 10-5 ~ 10-6 can be achieved when channel bit error rate is 10-2.
4.Long Transmission Distance ( Line-of-sight Distance）
5Km (BER=10-5@9600bps,Standard antenna length 10cm,the height of antenna 1.5m)；
7Km (BER=10-5@1200bps,Standard antenna length 10cm,the height of antenna 1.5m)；
5.Transparent data transmission
Transparent data interface used in transceivers is for meeting many standard or nonstandard user protocols.
Any false data generated in air can be filtrated automatically (What has been received is exactly what has been transmitted).
Transceiver conversion time：<10ms
6.Multi-channels,Multi Baud rate
Offer 8 channels, if needed, 16 or 32 channels are available to satisfy various configuration of communication under user’s demand at the same time.
Baud Rate：1200、2400、4800、9600、19200 etc.
7.High speed wireless communication and Big data buffer area
When air baud rate is greater than interface baud rate, unlimited data can be continuously transmitted.
When baud rate is less than or equal to interface baud rate, can transmit one frame 128 bytes of data.
8.Intelligent data control and no any extra programs required
Even for half duplex communication, no any excessive programs required. All RF system data transmission/reception and
other On-the-Fly conversion and control are performed by KYL-300M transceivers automatically.
9. Lower power consumption & Sleep function
With +5V power, the receiving current is less than 30mA, the transmitting current is less than 1.5A, and the sleeping current is less than 20uA.
10.High reliability, small and light
By using monolithic radio-frequency integrated circuit and single-chip MCU, the
transceivers have less peripheral circuit s, high reliability, and low failure rate.
11.Provides square wave transmission function for customers using non-standard coded .

1、When Module A transmits data and module B receives data
That is, the delay time that the terminal A (connected to the module A) sends data to the terminal B
(connected to the B module) by wireless. Which be fixed to the time for transmitting 15 bytes. This time is related to the air baud rate,
but not to the interface baud rate. details as follows:
2、亚游集团注册Module transceiver conversion time
That is, the time for converting from the receive state to the transmit state, or from the transmit state to the receive state. During this time (100us), the module cannot receive air data.
