I: About KYL-300I  
KYL-300I is a kind of low power wireless transceiver data module. with small size,  
low power consumption as well as good stability and reliability, it is widely used as  
wireless data transceiver in long-ranges, narrowband low power UHF wireless data  
transmitters and receivers with channel spacing as low as 25 KHz.  
II: Features of KYL-300I:  
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-300I provides 8 channels, expandable for 16, 32 channels according to  
requirements of users.  
7. Three connection methods with DB9 connector  
KYL-300I transceiver provides DB9 connector with three connections: a  
non-standard RS-232 port and a non-standard RS-485 port. USB interface port is  
also available. It can get power from PC directly.  
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.

1. Power supply  
The factory setting is +5V (7.5V-12V is also available, please specify when placing  
the order). Using better ripple factor, KYL-300I transceiver can share power supply  
with other equipments. If possible, a voltage-stabilizing chip with 5V voltage is  
more recommended than Switch power supply. But if only switch power supply is  
available, the jam caused by switch pulse should be avoided. In addition, the  
reliable grounding must be used if there is other device in the system. In case of  
failing to connect with the ground, it can form its own grounding but must be  
absolutely separated from the municipal electric supply.  
2. Connection Definition with terminal  
KYL-300I transceivers supply one 9-pin connector (JP1), their definitions and  
connection methods with terminals are shown in Table 1.

4. Setting of channel, interface, and data format  
Before using KYL-300I, you need to make simple configuration on your own  
needs to determine the channel, interface mode and data format. You can view or  
change the module's interface baud rate, channel and address code. Please read or  
set the parameters as per the testing software KYLCOM.exe (in products box).  
And the configuration is as follows:  
i. Channel configuration:

6. The Function-indicator light  
a. The LED indicator light will turn red for 0.5S once switched on.  
b. The LED indicator light will turn green continually while receiving data from  
air.  
c. The LED indicator light will turn red continuously when transmitting data into  
air after receiving data from COM.  
d. If the module moves to sleep mode, LED indicator light is always dark.  
7. Supported protocol and Transmit capability  
KYL-300I standard transceivers offer transparent protocol to support various  
applications and protocols. If the user needs 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 instruction:  
In order to reduce more consumption, KYL-300I transceivers support Sleep  
function. In sleep mode, the current consumption is less than 20uA.  
a. How to use the 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 enter sleep mode after finishing transmission.  
From sleep mode to working, it takes the transceiver 1ms after rising edge.  
To disable the opened sleep function of KYL-300I, the SLP (SLEEP) pin should  
be definitely connected with 0 or ground.  
b. Attentions about the use of sleep function:  
When the sleep function enabled, any supply glitches, such as switch dithering,  
fire striking or quick switching on and off may cause the transceiver moving to  
wrong sleep mode.  
Users can avoid this error by making a compulsive restoration once the CPU  
delays 100ms after switching on

9. Attentions about data transmission  
a. The delay time (tc) of conversion between transmitting and receiving is less  
than 1ms.  
Timing diagram:  
b. The delay time of transceivers between the first bit sent by TxD to the first  
bit received by RxD.  
As data processing happens on user’s data by KYL-300I transceiver using FEC  
(Forward Error Correction) or other correction algorithm, when RxD of  
KYL-300I 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:

c. Error dealing procedure:  
To enhance the reliability and stability of user’s systems, a verified bit or a  
Cyclic Redundancy Check (CRC) mode is highly recommended to resist wrong  
information while using KYL-300I modules.  
d. Large-number data transmission  
In theory, when the interface data rate is faster than the RF data rate, KYL-300I  
transceivers can sent unlimited-long data package, but any long packages more  
than 120B are not recommended. The length of each package should be between  
60~100B. We also recommend users to resist the wrong information by using  
Automatic Error Request Equipment (ARQ).  
Reasons:  
If the actual transmission BER (Bit Error Rate) is 10-4, 1 packet with 1KB data,  
which is about 10-thousand bits, is sent, theoretically, at least 1 bit will be  
received wrongly. So 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, it will resend this wrong packet using ARQ mode. So resending one  
more packet and the efficiency rate is reduced 10%, all data will be absolutely  
received correctly.

V. Network Application of KYL-300I  
The communication channel of KYL-300I 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-300I 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.
