KYL-300L

Features

 

  1、Frequency Band: 433MHz, 450MHz,470MHz,868MHz,915MHz etc ISM Frequency Band;

  2、8 channels, if needed, 16/32/64 channels are available to satisfy various configuration of communication at the same time;

  3、Baud Rate:1200、2400、4800、9600、19200、38400bps;

  4、Data format:8N1/8E1/8O1(Other formats can also be provided, such as 9-bit data bits to meet the requirements of multi-machine communication);

  5、Interface:RS232/RS485/TTL; 

  6、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);

  7、 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 +80°C;

  8、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 data loss;

  9、Compatible with KYL series other modules with medium power (1W, 2W), high power (5W), convenient and flexible networking;

 10、Complies with standard EN 300220 and ARIB STD-T67。

The Function-indicator light

1、 The LED indicator light will glitter red for 0.5S once after switched on.

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 always dark.


Timing Diagram

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:

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

Power supply:

    +3.3~6.0V 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.
