I-7540D-MTCP Ethernet/ Modbus to CAN Converter Quick Start User Guide Version 1.0 ------ 2 

 

2. Hardware Installation 

 

Users  need  to  make  a  hardware  connection  between  the  CAN  devices 

before the application. The details of this are illustrated below:   

 

Step1:    Set-up the 120

Ω terminator resistor of module A and B. Before going 

to  the  next  step,  check  if  the  JP3  is  enabled  or  not.  If  not,

 

it  is 

necessary  to  open  the  cover  for  each  I-7540D-MTCP  and 

re-configure  their  JP3  jumpers  to  enable  them  again,  as  shown  in 

below figure. 

 

Enable (default), 

(Activate)

Step2:    Power connection for the I-7540D-MTCP #A and I-7540D-MTCP #B.   

Connect the (R)Vs+ and (B)GND pins of the I-7540D-MTCP module 

to the DC power supply (10~30VDC).
