III．Features of KYL-200L  
1. Low power transmission: 500mW (default), 600mW~1W (optional).  
2. Carrier frequency: 433MHz (default), 400-470MHz, 868MHz, 915MHz  
(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 ensure the data’s resistance against 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  
-3  
is 10 , the reliable transmission distance is 3000m @1200bps and 2000m@9600bps  
respectively.  
5. Transparent data transmission  
Transparent data interface used in transceivers is to satisfy 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  
KYL-200L provides 8 channels, expandable for 16, 32 channels according to  
requirements of users.  
7. 2 ports with three connection methods  
KYL-200L transceivers provide 2 ports with three connections: a UART interface  
of TTL level, a non-standard RS-232 port and a non-standard RS-485 port.  
8. 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 specify our sales  
your requirements when placing your orders.  
9. 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-200L transceivers automatically.  
10. Lower power consumption & nice sleep function  
With +5V power, the receiving current is less than 25mA, the transmitting current  
is less than 300mA, and the sleeping current is less than 20uA.  
11. High reliability, small size and excellent performance  
By using monolithic radio-frequency integrated circuit and single-chip MCU, the  
transceivers have less peripheral circuits, high reliability, and low failure rate.  
12. Various options for configurable antennas.

4. Setting of channel, interface, and data format  
Before using KYL-200L, the user needs to make simple configuration to  
determine the channel, interface mode and data format based on his own needs.  
You can view or change the module's interface baud rate, channel and address  
code, parameter setting or reading as per the testing software KYLCOM in the PC  
(in products box).

6. The Function-indicator light  
a. The LED indicator light will turn red for 0.5S once switch on.  
b. The LED indicator light will turn green continually while receiving data from air.  
c. The LED indicator light will turn red continually when transmitting data into air  
after receiving from COM.  
d. If the module keeps sleep function, LED indicator light is always dark.  
7. Supported protocol and Transmit capability  
KYL-200L standard transceivers offer transparent protocol to support various  
applications and protocols of users. If you need to decrease his cost or ease the  
workload of terminal CPU, we can add other specific functions based on the  
transparent protocol, such as addressing, data acquisition, command interpretation,  
etc.

8. Sleep function  
In order to reduce consumption, KYL-200L transceivers support sleep function. In  
sleep mode, the current consumption is less than 20uA.  
a. How to use sleep function:  
The Pin8 ‘SLP’ in JP1 is the signal of sleep control. At high power level,  
transceiver stays in working mode. At low power level (<0.5V), transceiver stays  
in sleep mode. The SLP signal can convert transceiver from working to sleep  
mode in 1ms after falling edge. If the Sleep signal arrives when the transceiver is  
transmitting data, the module will move to sleep mode after finishing  
transmission. From sleep moves to working, it takes the transceiver 1ms after  
rising edge.  
To disable the opened sleep function of KYL-200L, the SLP (SLEEP) pin should  
be definitely connected with 0 or ground.  
b. Attentions about using sleep function:  
When the sleep function enabled, or any supply glitches, such as switch dithering,  
fire striking or quick switching on and off, may cause the transceiver switch to  
wrong sleep mode.  
After switching on, users can avoid this error by making a compulsive restoration  
once after the CPU delays 100ms.  
Sleep Timing Diagram:  
9. Attentions about data transmission  
a. The delay time (tc) of conversion between transmitting and receiving is less  
than 1ms.

b. The delay time of transceivers between the first bit sent by TxD to the first  
bit received by RxD.  
As data processing will be made on user’s data by KYL-200L transceiver using  
FEC (Forward Error Correction) or other correction algorithm, when RxD of a  
KYL-200L transceiver ‘A’ receives the data, then transmits it, the other one  
transceiver ‘B’ will have a delay (ts) to receive and transmit by TxD. Different  
RF data rate causes different delay time. Please see the specific delay time  
below:

Redundancy Check (CRC) mode is highly recommended to prevent wrong

information while using KYL-200L modules.  
d. Large-number data transmission  
In theory, when the interface data rate is faster than the RF data rate, KYL-200L  
transceivers can sent unlimited-long data package, but long packages more than  
120B are not recommended. The length of each package should be between  
60~100B. We also recommend our users to use Automatic Error Request  
Equipment (ARQ) to prevent wrong information.  
Reasons:  
-4  
What if the actual transmission BER (Bit Error Rate) is 10 , 1 packet with 1KB  
data which is about 10-thousand bits, is sent, theoretically, at least 1 bit will be  
received wrongly, then the 1KB information will never be received correctly.  
But if we package the data into 10 packets with 100B for each, when all 10  
packets are sent, there will be only 1 packet wrong according to this probability.  
After that, resend this wrong packet using ARQ mode. So by resending one more  
packet and the efficiency rate is reduced 10%, all data will be absolutely received  
correctly.  
10. Antenna configuration:  
Many appropriative antennas for low power RF modules are selected to meet  
different users’ antenna configurations. Please ask our Sales for more information  
about the antenna’s dimension and performance.

If you have special requirements on antennas, we can design and produce for you  
individually.  
V. Network Application of KYL-200L  
The communication channel of KYL-200L is half duplex, which is most suitable  
for the communication mode of point to multi-point. Under this mode, one  
master station must be set, and all of the rest are slave stations. A unique address  
is given to each station. The coordination of communication is controlled by  
master station that uses data frames containing address code to transmit data or  
command. Slave station will receive all of the data and command and compare  
the received address code with local address code. If they are different, the data  
will be deserted without any response. If those address codes are the same, it  
means the data is sent to the local. Slave station will make different responses  
according to the transmitted data or command and send back the data of response.  
All these jobs must be performed by upper protocol, and it is assured that there is  
only one transmitter-receiver in the state of transmission in the communication  
network at any instant moment so as to avoid the cross-interference.  
KYL-200L can also be used for point-to-point communication with easier  
operation. For the programming of serial port, all you have to do is to remember  
that its communication mode is semi duplex while always observing the time  
sequence of come-and-go for receiving and transmitting.
