IV: How to use the KYL-220  
KYL-220 provide RS-232, RS-485 and UART/TTL level interface ports which can  
be direct connected with PC, RS485 devices, monolithic processors and other  
UART components. Please find the schematic diagram below:  
1. Power supply  
The factory setting is +5V (needing 3.3V-3.6V, please notify us when placing the  
order). Using better ripple factor, KYL-220 transceivers can also share power  
supply with other equipment. If possible, a voltage-stabilizing chip with 5V voltage  
is much 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 equipment. 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-220 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-220, 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  
5. Installation dimension:  
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-220 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-220 transceivers support sleep function. In  
sleep mode, the current consumption is less than 20uA.  
a. How to use sleep function:  
Fax: +86-755-83408785  
sales02@rf-data.com  
www.rf-data.com  
ShenzhenKYLCommunicationEquipmentCo.,Ltd  
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-220, 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. The attentions of 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-220 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

c. Error dealing procedure:  
To enhance the reliability and stability of user’s systems, a verify bit or a Cyclic  
Redundancy Check (CRC) mode is highly recommended to prevent wrong  
information while using KYL-220 modules.  
d. Large-number data transmission

sales02@rf-data.com  
www.rf-data.com  
ShenzhenKYLCommunicationEquipmentCo.,Ltd  
In theory, when the interface data rate is faster than the RF data rate, KYL-220  
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 user antenna configurations. Please ask our Sales office for further  
information about the antenna’s dimension and performance.  
a. Helical SMA antennas  
KYL-ANT-433-10-SMA: 100mm helical SMA antennas with high gain and low  
cost, reach a long distance.  
b. Magnetic vehicle antenna  
KYL-ANT-O433S-300H1.5-SMA: include magnetic antenna base, suitable for  
equipment with metal shell, easy for fixing, effective to enhance the transmission  
distance.
