I: About KYL-300M
KYL-300M, RF data radio is designed to be low cost and high performance radio
modem. The new design makes the modem more flexible for different application in
various configurations. Basically, this type of modem is SMART enough to be
customized to best meet end user’s requirements. Users don’t have to pay the features
that never be used in their projects.
II: Features:
I. Features of KYL-300M
1. Low power transmission with 2W.
2. With 433MHz as factory default carrier frequency, 400~470MHz is available if
needed.
3. High anti- interference and Low BER (Bit error Rate)
Based on the Gaussian Frequency Shift Keying (GFSK) modulation, the
high-efficiency forward error correction channel encoding technology is used to
enhance data’s resistance to both transient interference and random interference and
the actual bit error rate of 10
-5
~ 10
-6
can be achieved when channel bit error rate is
10
-2
.
4. Long Transmission Distance
Within the visible range, when the height of antenna is higher than 2m and The Bit
Error Rate (BER) is 10
-3
, the reliable transmission distances respectively is 7000m
@1200bps, and is 5000m@9600bps.
5. Transparent data transmission
Transparent data interface used in transceivers is for meeting many standard or
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-300M transceivers offer 8 channels, if needed, 16 or 32 channels are available
to satisfy various configuration of communication under user’s demand at the same
time.
7. 2 ports with three connection methods
KYL-300M transceivers provide 2 ports with three connections, ports: a UART
interface of TTL level, a non-standard RS-232 port and a non-standard RS-485 port.
USB interface port is also available if needed.
8. Big data buffer area
With optional interface baud rate: 1200/4800/9600/19200bps and 8N1/8E1/8O1
data format (set 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.
9. Intelligent data control and no any extra programs required
Even for half duplex communication, no any excessive programs required. All RF
system data transmission/reception and other On-the-Fly conversion and control are
performed by KYL-300M transceivers automatically.
10. Lower power consumption & Sleep function
With +5V power, the receiving current is less than 30mA, the transmitting current
is less than 1.5A, and the sleeping current is less than 20uA.
11. High reliability, small and light
By using monolithic radio-frequency integrated circuit and single-chip MCU, the
transceivers have less peripheral circuit s, high reliability, and low failure rate.
12. More options of configurable antennas for user different applications.
13. Watchdog monitor
Watchdog monitors the inner function, so it can change the traditional product
structure and also improve the reliability of our modules.
14. With beautiful metal shell.
III: Application of KYL-300M:
KYL-300M RF data radio is suitable for:
* AMR Automatic Meter Reading
* Wireless alarm and security systems
* Building automation, security, wireless monitoring and control of room equipment,
Access Control System;

collection system;
IV: How to use the KYL-300M
KYL-300M provide RS-232, RS-485 and UART/TTL level interface port for direct
connection with PC, RS485 devices, monolithic processors and other UART
components kinds of applications. The schematic diagram is shown below:

1. Power supply
The factory default setting is +5V(7.5V-12V will inform when placing the
order).By using better ripple factor, KYL-300M 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-300M transceivers supply one 9-pin connector (JP1), their definitions and
