GFSK 868mhz / 434 Mhz RF Module 16 Channel Wireless RS232 Module
JZX871 the use of transparent transmission, in order to ensure the reliability and stability of the user's
system, plus the transmission checksum or CRC checksum error detection mode, the error data
retransmission. Transceiver module buffer of 512bytes, means that users can be in any state 512bytes
of data transfer 1, when the speed is greater than the serial port is set to air rate, is theoretically unlimited
length can send information packets, but does not recommend users to send long data packets, the
proposed length of each packet data between 60 ~ 100B, generally not longer than the 120B, and
recommended user program using the ARQ mode, the error data packets retransmission.
Sleep Mode:
JZX871 divided into dormancy release version with no sleep.JZX871 sleep after the current is 10uA.
JZX871 hibernation wake-up mode for the hardware. Wake is the fifth through the interface hardware
input pin high to sleep, wake-up input low. If the user has a sleep function JZX871, but do not want to use
the hibernate feature, available through JZX861 pin 5 to ground,then achieve.

1. Long transmission distance
Within the range of visibility, the reliable distance is >800m.
2. Transparent data transmission
Transparent data interface is offered to suit any standard or nonstandard user protocol. Any false data generated in the air can be filtrated automatically (What has been received is exactly what has been transmitted). The change time between receiving and sending is <10ms.
3. Multi- channel
The standard JZX871 configuration provides 16 channels to meet the multiple communication combination mode of the user.
4. High speed wireless communication and Large data buffer zone
When the RF baudrate is bigger than COM baudrate,allowing to transmit unlimited length data at one time, when the RF baudrate is smaller or equal to the COMs,allowing the transmission of 255 Bytes data.
5. Low power consumption
When transmission power is 1W,The Transmission current<35mA,Receiving current<30mA,sleeping current <1uA.
