1.12.2 ALP Does Not Detect the EVM
If the window shown in Figure 1-18 opens after starting the ALP software, double check the hardware setup.
Figure 1-18 ALP No Devices Error - Check the device manager to make sure that the USB driver is installed. There should be a “HID-compliant device” under the “Human Interface Devices” as shown in Figure 1-19.
- Check to make sure the software starts with only “DS90Ux949” in the “Devices” drop-down menu. If there are more devices then the software is most likely in demo mode. When the ALP is operating in demo mode there is a “(Demo Mode)” indication in the lower left of the application status bar as shown in Figure 1-20.
- Select the “Preferences” drop-down menu and un-check the “Enable Demo Mode” check mark to disable the demo mode.

Figure 1-21 ALP Preferences Menu After demo mode is disabled, the ALP software will poll the ALP hardware. The ALP software will update and only have “DS90UH949” or "DS90UB949" under the “Devices” drop-down menu.
