433mhz RF Module, TTL/RS232/RS485 For Automatic data collection system JZX877
Communicated Module
JZX877 wireless module with all the JZX87 series of models to communicate with each other.
Communication as long as you pay attention to the following:
A, select all the modules to the same channel.
B, you have the same communication module of the air rate.
C, the communication module, power supply, interface connection is connected.
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.
Note: If the user interface in use 1 foot terminal is not connected, the radio work in normal working
condition.
