I. Features of KYL-300H
1. Low power transmission with 5W, 6W~7W is available if needed.
2. With 433MHz as factory default carrier frequency, but 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 10km @1200bps,
and is 8km@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-300H 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-300H 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-300H transceivers automatically.
10. Lower power consumption & Sleep function
With +12V power, the receiving current is less than 30mA, the transmitting current is
less than 1.5A, and the sleeping current is less than 1mA.
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.

III. How to use KYL-300H
KYL-300H can provides RS-232,RS-485 and TTL level interface port for direct connection
with PC, RS485 devices, monolithic processors. The schematic diagram is shown below:
1.
Power supply
The factory default setting is +12,
±1.2V
DC. By using better ripple factor, KYL-300H
transceivers can also share power supply with other equipment. If possible, a
voltage-stabilizing chip with 12V 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.

4. Setting of channel, interface and data format:
Before using KYL-300H, the user needs to make simple configuration based on its own
needs to determine the channel, interface mode and data format.
The user can change or view the module's interface baud rate, channel and address code.
