Set each unit with a different Address (0 ~ 30). Then by using RS485 connect 
the first power supply in the chain to a PC. Now, multiple units daisy-chained 
via RS485 can be controlled by one PC by using the commands specific for 
multi-unit connection. See “Programming Guide” section for details. The 
following diagram shows how to connect the power supply by using RS485.
