I-7540D-MTCP Ethernet/ Modbus to CAN Converter Quick Start User Guide Version 1.0 ------ 3 

Step3:    Ethernet port connection:   

By  using  Ethernet  hub  device  to  connect  the  Ethernet  port  with  the 

I-7540D-MTCP  #A,  I-7540D-MTCP  #B  and  the  PC  with  standard 

network cable 

respectively

Step4:    RS-232 connection:   

Connect the RS-232 ports of the I-7530A-MR #B to the COM port of 

the PC by using the attached cable CA-0910. The wire connection is 

shown below.   

 

Step5:    CAN bus connection:   

Connect the CAN ports of these two I-7540D-MTCP modules to the 

CAN network by using the following structure.   

 

3. The I-7540D-MTCP Parameters Configuration 

 

Before testing the I-7540D-MTCP converter, users need to configure the 

RS-232, Ethernet and CAN parameters via the I-7540D-MTCP Utility tool. The 

details of this procedure are shown below.   

Step1:    The default network setting of the I-7540D-MTCP is shown below.   

IP: 192.168.255.1   

Mask: 255.255.0.0   

Gateway: 192.168.0.1   

Before communicating with the I-7540D-MTCP, you must change the
