of the LTC6954. Follow the procedure below.
The DC590 and LTC6954_GUI application are required to 

control the DC1954A through a personal computer (PC).

DC590 Configuration

Place the DC590 jumpers in the following positions (refer 

to Figure 2):

JP4:

  EE 

Must be in the EN position.

JP5:

  ISO 

ON must be selected.

JP5:

  SW 

ON must be selected.

JP6:

  VCCIO 3.3V or 5V must be selected. This sets the 

    

SPI  port  to 3.3V  or 5V  operation, 3.3V  

    

operation is recommended.

Connect the DC590 to one of your computer’s USB ports 

with the included USB cable.

LTC6954_GUI Installation

The LTC6954_GUI software is used to communicate with 

the LTC6954. It uses the DC590 to translate between USB 

and SPI-compatible serial communications formats. The 

following are the LTC6954_GUI system requirements:

• 

Windows Operating System: Windows XP, Windows 

2003 Server, Windows Vista, Windows 7
