Bộ chuyển đổi CAN sang Ethernet + RS-232/485 ICP DAS I-7540D-G CR
The I-7540D series are CAN to Ethernet converters, and are usually applied as an Ethernet to CAN/RS-232/485 Device Server. They support socket access functions and virtual COM port technology which helps users to get the CAN, RS-232, RS-485 data via virtual COM port. The I-7540D series also provide transparent mode, which enables CAN networks to be coupled together over the Internet/Ethernet, whereby remote monitoring and control is possible. By the features of tiny operating system, protocol independence, small casing and flexibility, it is able to widely fit various RS-232, RS-485 and CAN applications, which may be based on private RS-232 protocol, private CAN protocol, Modbus protocol, CANopen protocol, DeviceNet protocol or J1939 protocol.

Data Process
The VxComm technology can be used to simulate COM/CAN ports of the I-7540D to become a COM port of PC . With the help of VxComm driver, users can access the remote COM/CAN ports of the I-7540 just as them would access the PC’s COM port. The block diagram of data processes in I-7540D is given as follows:
