Good quality Long Range RF Module for sales
We are very satisfied with their service and products, I bought their long range audio modules, at the begining I could not installed the modules, they taught me step by step and finally I got it! The modules work well and help me won the bid! Best Regards! Santithamkul

—— Santithamkul from Thailand

I visited many factories before I placed order for my radio modem. The reason I choose them is their professional skill and their excellent service. They do very best in every details. I like this factory and also like their lovely sales people! I will recommend more business partners to do business with them.

—— Makarov From Russia

Very excellent products and excellent service! I visisted many factories in China but none of them were meet my request! I finally chose them because many of my partners recommanded this company to me! The I/O Modules they sold were brilliant! It makes us more convenient with wireless solution!

Detailed Product Description
Name: 8 Channels Short Range RF Module Distance: 2km-3km
Power: 800mw Frequency: 433MHz(450MHz-470MHz, Customize)
Interface: RS232/RS485/TTL Baud Rate: 1200/2400/4800/9600/19200bps

314U 800mW, Wireless Transmitter 470MHz RS232 RS485 TTL 8/16/32/64 Channel Wireless Data Transparent Transmission

 

•Features


 

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

2. 8 channels, if need, 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;

•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:

Baud rate (Bps) Delay time(ms)
19200 8
9600 15
4800 30
2400 60
1200 120

 

 

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:

+12-30V 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.
