I: About KYL-200U
KYL-200U, the micro power wireless transceiver data module is used as the wireless
data transceiver in short-ranges, with the small size, weight and power consumption
and good stability and reliability. Narrowband low power UHF wireless data
transmitters and receivers with channel spacing as low as 25 KHz.
II: Features:
I. Features of KYL-200U
1. Low power transmission with 10mW, 50~100mW is available if needed.
2. With 433MHz as factory default carrier frequency, but 400-470MHz, 868MHz,
915MHz 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 1000m
@1200bps, and is 600m@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-200U 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-200U 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.
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-200U transceivers automatically.
10. Lower power consumption & Sleep function
With +5V power, the receiving current is less than 20mA, the transmitting current
is less than 40mA, 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.

1. Power supply
The factory default setting is +5V(3.3-3.6V will inform when placing the order).By
using better ripple factor, KYL-200U 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.
