I-7540D CAN-Ethernet Gateway User’s Manual (Version 1.8, March/2021)

VxComm Technology 

The  I-7540D  is designed as a RS-232/RS-485/CAN  to Ethernet  Gateway. So it 

follows that they can be used to link these RS-232/RS-485/CAN devices to central 

computer as follows: 

 

Figure 1-2:  Application of I-7540D 

Compared to the RS-485 network, these Ethernet network hubs are already in 

existence for system network. Therefore, the RS-232 devices can find the closest 

hub and link to the central computer with the help of the I-7540D. The Ethernet 

network is extremely popular and already existing for most applications, hence, 

this approach is a very successful. In general, it is more difficult to write a TCP/IP 

program than a COM 1/2 program. 

Therefore

,

  the VxComm technology is 

developed to simulate COM-ports of the I-7540D to become COM 3/4/5…/256 

of the central computer.

 Then users can write a COM port program to link these 

RS-232/RS-485/CAN  devices  and  need not to concern themselves with any 

TCP/IP problem.
