I: About KYL-300M
KYL-300M, RF data radio is designed to be low cost and high performance radio modem. The new design makes the modem more flexible for different application in various configurations. Basically, this type of modem is SMART enough to be customized to fully meet end user’s requirements.

II: Features of KYL-300M:
1. Low power transmission: 2W
2. Carrier frequency: 433MHz (default), 400-470MHz (optional)
3. High anti- interference and Low BER (Bit Error Rate)
Based on GFSK modulation, high-efficiency forward error correction channel encoding technology is used to enhance the data’s resistance to both transient interference and random interference. The actual BER can be achieved to 10-5~ 10-6 when channel BER is 10-2.
4. Long Transmission Distance
Within the visible range, when the height of antenna is higher than 2m and The BER is 10-5, the reliable transmission distance is 7km @1200bps, and is 5km@9600bps respectively. 
5. Transparent data transmission
Transparent data interface used in transceivers is to meet many standard and nonstandard user protocols. Any false data generated in air can be filtrated automatically (What has been received is exactly what has been transmitted).
6. Multi-channels
We provide 8 channels, expandable for 16, 32 channels according to customers’ requirements.
7. Big data buffer area
With optional interface baud rates: 1200/4800/9600/19200bps and 8N1/8E1/8O1 data format (decide by user), the transceiver can transmit unlimited data frames with flexible user program.
Note: the RF data rate is only settled down before delivery; please inform our sales when placing your orders.
8. Intelligent data control system and no other extra programs required
Even for half duplex communication, no other excessive programs are 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 & nice 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 size and excellent performance
   High sensitivity, small size is suitable for the order-dish system. With Long transmission distance, strong penetrability, it is preferable for handheld terminal.
11. More options of configurable antennas for user different applications.
12. Watchdog monitor
Watchdog monitors the inner function, so it can change the traditional product structure and also improve the reliability of our modules.
13. with beautiful metal shell.
