I: About KYL-500L  
KYL-500L, the micro power wireless transceiver data module, is designed for  
order-dish system. With small size, low power consumption as well as good  
stability and reliability, it is also widely used for other embedded systems like  
AMR.  
II. Features of KYL-500L  
1. Low power transmission: 400mW  
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 2km @1200bps, and is  
1.5km@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  
requirements of customers.  
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-500L transceivers automatically.  
9. Lower power consumption & nice sleep function  
With +3.3V to 3.6 power, the receiving current is less than 25mA, the  
transmitting current is less than 200mA, and the sleeping current is less than  
2
