Place of Origin: Guangdong China (Mainland) Brand Name: JZ Model Number: JZ877 size: 63mm*43mm*15mm weight: 60g cover: metal Packaging & Delivery Packaging Detail: standard package for export Delivery Detail: 2-3 days after received the payment Specifications 1.TTL/RS232/RS485 2.433/868/915MHz 3.500mW,up to 1-3km 4.1200/2400/4800/9600/19200bps 5.Good stability and reliability Low Power Radio Transmitter Technical specification of JZ877:Serial numberItemParameterNote1Modulation modeGFSK 2Work frequency433MHZ 868/915mhz is possible3Transmission power0.5W 4Transmitting current<360mA 5Receiving current<45mA 6.Sleeping current0.1mA 7Receiving sensitivity-123dbm(1200bps) 8Channel amount16 channelUser setting9Working temperature-20-+65°C10Working humidity10%~90%(relative humidity without condensation) 11Antenna impedance:50 12Power supplyDC 5±0.5V 13Dimension63mm×43mm×15mm 14InterfaceTTL,RS232,RS485user can choose15Reliable transmit distance1-3Km Features:1. Low Power consumption and receiving sensitivity Transmission power <0.5W, TX current<360mA, RX current<45mA, sleeping current <0.1uA.High receiving sensitivity: -123dbm.2. Saving power modelJZ877 have three Saving power models:awaken from Hardware,awaken from COM Port, awaken from Air;3. Modulation mode and Frequency Modulation mode:GFSK,Frequency:433MHZ.Also,868mhz and 915mhz is possible.4. High anti- interference and low BER(Bit error Rate)Based on the GFSK modulation mode, the high- efficiency forward error correction channel encoding technology is used to enhance datas resistance to both burst interference and random interference and the actual bit error rate of 10-5 ~ 10-6 can be achieved when channel bit error rate is 10-2.5. Long transmission distance Within the range of visibility, the reliable distance is >2000m ().6. 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; 7. Multi- channelThe standard JZ877 configuration provides 16 channels to meet the multiple communication combination mode of the user.8. 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 . 9. Intelligent data control and the user doesnt need to prepare excessive programs Even for semi duplex communication, the user doesnt need to prepare excessive programs, only receiving/transmitting the data from the interface. JZ872 will complete the other operations automatically, such as transmission/receiving conversion in the air, control, etc.10. High reliability, small and light Single chip radio - frequency integrated circuit and single chip MCU are used for lessened peripheral circuits, high reliability, and low failure rate. 11. Watchdog monitor Watchdog monitors the inner function, it changes the traditional product structure and also improve the reliability of our modules.
