After the setting is successful, the new baud rate will be saved in the FLASH inside the reader, and will not be lost 

after the reader power off, restart the reader to make the setting effective. At this time, it must communicate with the 

reader at the new baud rate. 

caution: 

 

If  the  interface  used  by  the  user  is  a  TCP/IP  interface,  then  the  TCP/IP  module  must  be  changed  to  the 

corresponding  serial  port  rate.  For  specific  operations,  please  refer  to  the  TCP/IP  interface  configuration 

document attached with the reader. 

 

Inventory tags in real-time mode will generate a lot of data, please try to use 115200bps baud rate. 

 

 

 

 

Develop your own RFID Application 

 

Users can operate most of the functions of the reader through the demonstration program, but in the actual application 

environment, it is necessary to develop their own programs. 

The accompanying document: R2000 module serial interface communication protocol V4.0.doc provides a complete 

interface for operating the reader. 

This  interface  is  based on  serial  communication,  so  no matter  the  user's  physical  interface  is  RS232  or TCP/IP,  the 

reader will follow the definition of this interface. 

The demonstration  program provides an important function, which is the transmission record of the serial port. The 

user  can compare the communication  protocol document  with  the actual serial port data during  the operation of the 

demonstration program to quickly grasp the content of the communication protocol. 

 

After  checking  the  Open  serial  port  monitoring  check  box  in  the  lower  right  corner,  all  upstream  and  downstream 

serial port data will be recorded, as shown in the figure below (after opening the serial port monitoring, the response 

speed of the software will become slower, so you should usually close the serial port monitoring.):
