DEMO MANUAL DC2442A

The DC1613 USB-to-I

C adapter interfaces the PC run-

ning LTpowerPlay to the DC2442A board. Connect the

DC1613 adapter to the PC through a USB cable, and

connect the DC2442A board through the ribbon cable

to connector J2 (Figure 3).

Launch the LTpowerPlay GUI on the PC. The software

identifies the DC1613 controller, then the DC2442A board,

and begins communicating through the I

C bus with the

LTC4282. Once this communication has been established,

the GUI displays its main window (Figure 4).
