1. Power supply
The factory default setting is +5V(7.5V-12V will inform when placing the
order).By using better ripple factor, KYL-200L transceivers can also share power
supply with other equipment. If possible, a voltage-stabilizing chip with 5V voltage
is more recommended as the only power supply than Switch power supply. But if
only switch power supply available, the jam by switch pulse to the transceivers
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-200L transceivers supply one 9-pin connector (JP1), their definitions and
connection methods with terminals are shown in Table 1.

6. The Function-indicator light
a. The LED indicator light will glitter red for 0.5S once after switched on.
b. The LED indicator light will glitter green continually while receiving data from
air.
c. The LED indicator light will glitter red continuously when transmitting data into
air after receiving from COM.
d. If the module enables the 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 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:
Due to reducing more consumption, KYL-200L 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. In high power level,
transceiver stays in working mode. In 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-200L, the SLP (SLEEP) pin should
be definitely connected with 0 or ground.
b. Attentions about use of sleep function:
When the sleep function enabled, any supply glitches, such as switch dithering,
fire striking or quick switching on and off, could cause the transceiver to be
10

switched to the 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:
8. The attentions of 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.
Due to a 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

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 resent the 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 any long packages more
than 120B are not recommended. The length of each package should be between
60~100B. We also recommend user to resent the wrong information using
Automatic Error Request Equipment (ARQ).
The analyzing as below:
What 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, 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 for meeting
different user antenna configurations. Please ask our Sales office for further

V. Networking 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
13
Fax: +86-0755-83408785
kyl03losia@gmail.com
www.rf-data.com
Shenzhen KYL Communication Equipment Co., Ltd
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.
