Connec ng to a device

            Using  a  network  cable  to  connect  it  is  the  most 
direct  and  safe  way  of  connec ng.  Use  a  network 
cable  to  connect  the  PC's  network  port  directly  to 
the  processor's  Ethernet  port,  and  make  sure  that 
the  computer's  I P  is  set  to  automa cally  get 
connec on (DHCP).

in  order  to  get  things  working  follow  this  ac ons 
s e q u e n c e :  S e

Protocol Version 4 (TCP/IPv4)---Select Automa c Get 
IP address.

A er  the  network  cable  connec on  is  confirmed, 
double-click  the  MIR-A  series  so ware,  the  device 
will  be  automa cally  discovered  and  a  pop-up 
window will prompt.

          Use  RS485  protocol  connec on,  through  USB  to 
RS485 device, you can get the serial port of RJ45 port 
and  connect  directly  to  RS485-IN/OUT  on  the  rear 
panel. The RS485 input and output on the rear panel 
are  designed  with  loop-out  design.  When  only  one 
device  is  connected,  Can  be  plugged  into  RS485-
IN/OUT at will.

When using  the  USB  interface  to connect,  you need 
to pay a en on to the following points.

*  When  your  PC  opera ng  system  is  Windows  XP  or 
Windows7,  you  need  to  install  the  STM32  virtual 
COM  driver  so  that  the  processor  can  be  correctly 
iden fied and connected.

*  When  your  PC  opera ng  system  is  Windows  8  or 
above, there is usually no need to install a driver, and 
the  system  will  correctly  iden fy  the  processor.  (If 
the  driver  is  not  installed  automa cally,  install  the 
STM32 virtual COM driver manually).

7.    Use of MIR-A series so ware
Minimum  system  requirements  for  running  MIR-A 
so ware:
Opera ng system               Microso  Windows 
CPU            

                      

single core 2.0GHz

Running memory                2GB 
Storage space                      1GB 
Need  Microso   Net  Framework  4  or  higher  and 
Microso  Visual C++2015-2022
The  M I R -A  series  provides  3  kinds  of  control 
interfaces,  namely  USB/RS485/TCP  IP,  and  there  is 
no  need  to  set  up  the  connec on  switching  of  the 

three ways
