3.4 Launching the OPT4001EVM Software

With the OPT4001YMNEVM properly connected, launch the Latte EVM GUI software from the Windows

Start

menu. The software launches with a screen similar to that shown in

Figure 3-11. OPT4001 Main Operation Screen

If the message shown in

appears when the OPT4001EVM GUI software is launched, this means

that the EVM motherboard was not detected. Check the USB connection and that the motherboard appears in
the device manager as shown in

. A green light will appear on the motherboard if it is receiving power

from the PC and the GUI "start capture" button has not been enabled.
