Figure 4.9 Adding an IP address

 

Enter  the  content,  and  click  the  Add  button.  Press  OK.  Now  you  can  communicate 

with the CANSwitch-AF2S2 device. 

4.2.5  Modifying the Local IP Address 

In  the  operating  system,  click  the  Start  button  Control  Panel  Network  and  sharing 

center  to  modify  the  advanced  sharing  settings,  select  the  "Local  Connection" 

corresponding to the network card connected to the CANSwitch-AF2S2 device, right-click 

and choose "Properties". In the displayed dialog box, select "Internet Protocol Version 4 

(TCP/Ipv4)"  and  click  "Properties".  The  page  shown  in  Figure  4.10  is  displayed.  Select 

[Use the following IP address], and enter the IP address 192.168.0.22, the subnet mask 

255.255.255.0,  and  the  default  gateway  192.168.0.1  (the  DNS  part  can  be  left  blank). 

Click "OK" on this page, and wait until the system is configured. 

 

Figure 4.10 TCP/IP Properties window

 

Now you can communicate with the CANSwitch-AF2S2 device. 

4.3  TCP Server Mode 

4.3.1  System Block Diagram 

In TCP Server mode, CANSwitch-AF2S2 will not actively connect with other devices. 

It always waits for the connection of the client (TCP Client), and can perform two-way data 

communication after establishing a TCP connection with the client. Figure 4.11 shows the 

communication establishment process.
