KST-RX820
Low power transmitter,it has transceiver Instruction
1. Transmitter power is 500mW,when it work transmit ,the Pilot lamp is red ,when it work receiver ,the pilot lamp is green
2. when the frequency is ISM , it no need apply Besides
load frequency is 433MHz, if special requirements are also available for the 315/868/915MHzy
3.high anti-jmming and low wrong code
Basic on FSK modulation , adopting efficient forward error correction channel encoding technology , improve the data ability that against burst interference and random interference.
4. high transmission ability reliable transmission distance is about 1000 meters (BER = 10-6 @ 1200Bit / S).
5, transparent data transferTo provide transparent data interface, interface baud rate is 1200/2400/4800/9600/19200Bit/s, format is 8N1/8E1/8O1 user can set. Air baud rate 1200/2400/4800/9600/19200Bit/s user settings.
6 .many channel
Standard modules provide 8 channels, to meet a variety of communication combinations for customers
7. 4 kind of interface modeModule provides four kinds of interface mode, according to the user's requirements can be defined as a standard RS-232 / TTL / RS-485/USB interfaces.
8.large data bufferswhen the data be transmission,it will over at least transfusion 120Byte data frame, when the air is large than the baud rate serial port baud rate, at least more than one data frame transmission 200K.
9. intelligent data controlUsers do not need to communicate other control, as long as from the interface / receive data can be, other, such as air / receive switching, control operations, the module can be done automatically.
10.low power
Receiver power is 30 mA, sender power is 350mA
11.High reliability,mini-volume ,light weight
Adopting A single chip radio frequency integrated circuits and chip MCU, less external circuitry, high reliability.
