Industrial RF Transmitter And Receiver Module 2km RS232 Interface JZX877 with Antennas


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.


If the actual error rate 10-4, users need to send 1KB about 10000bit information, if the 1KB data as a

packet, sent at least theoretically, there will be a data error in the receiver, then the 1KB data can never

be received correctly. If it is divided into 10 packages, each package 100B, then send 10 packets, the

packets according to a probability of only 1 error, the error in the form of a packet retransmission by

ARQ 1, although it took more than 1 packet and the efficiency decreased by about 10%, but it can

guarantee all the information is correctly received.
