JZX2303 high-power high-speed data transmission radio
Transmission distance: 10Km Power: DC12V/20W Volume: 165MM/95MM/40MM (excluding antenna)
Product details
Functional Features
☆ Transmitting power of 20W, high receiving sensitivity of -120dBm.
Receive current<100mA, 20W: transmit current<8A.
☆ Modulation method: GMSK， The carrier frequency is 230MHz.
Based on GMSK modulation method and efficient communication protocol, when the channel error rate is 10-2, the actual error rate can be obtained between 10-5
10-6.
☆ Adopting digital frequency synthesis technology, dual phase-locked loops and dual VCOs, the transmission start-up time is less than 8ms, which is significantly better than the national standard requirements
100ms requirement; The shortest data delay is 25ms.
In line of sight conditions, the antenna height is greater than 8 meters and the reliable transmission distance is over 10Km.
Provide a transparent data interface that can adapt to any standard or non-standard user protocol. Automatically filter out noise signals generated in the air
Number and false data (sent as received).
The standard configuration of JZX2303 radio station provides 64 channels, meeting the needs of users for multiple communication combinations. JZX2303 radio station
It can provide two communication baud rates of 9600bps and 19200bps in the air, and the serial port can provide 4800bps, 9600bps, and 19200bps
There are six interface baud rates of 38400bps, 57600bps, and 115200bps, and the wireless transmission rate is directly proportional to the interface baud rate,
To meet the needs of customer devices for multiple baud rates.
The maximum amount of data transmitted at the same speed in the serial port and air can reach 50K bytes.
Even with half duplex communication, users do not need to write extra programs, as long as they receive/send data from the interface, other than in the air
The radio station can automatically complete operations such as receiving/sending conversion, network connection, and control.
☆ Adopting high-performance single-chip processors, with fewer peripheral circuits, high reliability, and low failure rates.
