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. 

 

 

 

Packing&Delivery:

 

1.  We can ship the products all over the world

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

 

 

Troubles: Short Distance

 

Cause and Remedy:

 

*  Environment very bad or the antenna is blocked

*  Power match or not. Voltage and current is large enough

*  The existence of the same frequency or magnetic or electrical interference, or replacement of the 

   channel away from sources of interference
