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.
