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

5.1.1 Architecture

The

VxComm Driver

creates COM port(s) and maps them to the COM port(s)

of the

I-7540D

. The user's RS-232 client programs need only to change to the

different COM port to access the serial devices that are allocated to the Internet or

Ethernet network via the

I-7540D
