About JZX877:
JZX877 data transmission module is highly integrated low-power half-duplex wireless data transmission
module, which uses "TI" high-performance RF chips and high-speed microcontroller. Module provides
16 channels, and is equipped with professional set-up software for the user to change parameters, the
module with transparent transmission mode, no user-written set and transmission procedures; you can
transmit data of any size. Module size is small, industrial design, the use of voltage is wide, easy to
use.
Sleep mode module
Hardware wake-up mode, the radio's sleep current of less than 1mA.
Wake-up work in the use of hardware, in the user interface input terminals 1 foot low, the radio will
enter sleep mode, MCU about 1ms of sleep.
When to make the radio into the normal working hours, should be in the user interface, the input
terminal 1 foot high, the radio will enter the normal mode, MCU is working on several ms to enter into
the state, but in order to send data to the stability, the user should be more than 60ms delay for data
transmission.
Applications
Intelligent home control system; Wireless RFID tag;Wireless sensor;POS terminal;
Industrial data transmission;Automatic data collection system;Wireless remote control;
Wireless AMR for water, gas and hot, electricity and other meters.
In the work on, JZX877 There are two ways of working, first for the conventional model, which module is
powered On, is in receive mode; you also can be sending data. The second is sleep mode, that is,
through the power module in a dormant state, it must be user-controlled mode Wake-up pin block,
the module can send and receive data. In the application of JZX877 module, the module uses a wide
range of voltage, 5V power supply module, the voltage of DC 4.5-5.5V. Users in the use of power to DC
power supply, the current must be greater than 500mA, but to choose a good power supply ripple.
Troubles Q1 : Between devices not communicated
Cause and Remedy:
* Frequency inconsistency
* Without power
* Module has destroyed
* The pin of sleep mode not set
* Communication at both ends of the air rate, parity inconsistency
