 DATA Connections (Example of 12-Modules) 

 

Step1

: Set up the DIP Switches as per the picture below. 

Step 2

: Connect the CAN and Link ports, starting from the HV Box port CAN A and LINK, then chain connection as 

shown below. 

 
 

The HV Box must be set up before turning it on.  The DIP addresses must follow the picture below to enable the CAN 

communication. The last module of the series must be terminated by addressing the module as shown in the picture to end the 

CAN line.
