KYL-300 500mW RF Data Transceiver, Point To Multi Point
433mhz/450mhz/470mhz RF Transceiver
2. 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
3. Industrial-grade design, uses high-quality devices and
high-precision Temperature compensation crystals to meet the needs
of all-weather work. Reliable operating temperature up to -35°C to
4. Big data buffer area, the transceiver can transmit unlimited
data frames with flexible user program.the terminal can
continuously send data to the module without buffer overflow and
5. Compatible with KYL series other modules with medium power (1W,
2W), high power (5W), convenient and flexible networking.
6. Complies with standard EN 300220 and ARIB STD-T67.

1. The LED indicator light will glitter red for 0.5S once after
2. The LED indicator light will glitter green continually while
receiving data from air.
3. The LED indicator light will glitter red continuously when
transmitting data into air after receiving from COM.
4. If the module enables the sleep function, LED indicator light is
1. When Module A transmits data and module B receives data
That is, the delay time that the terminal A (connected to the
module A) sends data to the terminal B (connected to the B module)
by wireless. Which be fixed to the time for transmitting 15 bytes.
This time is related to the air baud rate, but not to the interface
baud rate. details as follows:
Table: Baud rate and delay time
|Baud rate (Bps)||Delay time(ms)|
2.Module transceiver conversion time
That is, the time for converting from the receive state to the
transmit state, or from the transmit state to the receive state.
During this time (100us), the module cannot receive air data.
•How to use KYL series micro power wireless data module
+3.3-6V DC, According to the needs of users, it can share the power
with other devices, but please select a power supply with a better
ripple factor. If conditional, 5V regulators can be used to supply
power alone. It is recommended not to use the switching power
supply. If you must use the switching power supply, please pay
attention to the interference due to switching pulse. In addition,
if there are other devices in the system equipment, it must be
grounded reliably. Otherwise, it can be self-contained, but it must
be completely separated from the city electricity. The maximum
output current of the power supply should be more than 1.5 times
the maximum operating current of the module.
