915mhz Telemetry Modem RS232 / RS485 800m  - 1200m For Led Display

 

JZX871 set parameters, the market is no longer used wireless modules used in the traditional way to 

change the parameters of the jumper, causing long-term use because it brings bad, options less dynamic 

change is not easy, a lot of inconvenience. JZX871 using the serial port setting parameters easy and 

quick, easy set refers to the chip embedded in the user program and operating software in the 

background. Meanwhile module 1200/2400/4800/9600/19200/38400bps six kinds of rate and 8 frequency provide UART / TTL, RS232, RS485 three kinds of interfaces. 

Choice for users.

 

In the work on, JZX871 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 JZX871 module, the module uses a wide 

voltage range, but also be divided into two kinds of voltage, the first for the 5V power supply module, 

also known as conventional module, the voltage of DC 4.5-5.5V. 

 

The second is 3V power supply modules, custom module for the user, the voltage of DC 2.7-3.3V; 

users in the use of power to DC power supply, the current must be greater than 50mA, but to choose 

a good power supply ripple.
