The software should start with only “DS90UB921-Q1” in the “Devices” pull 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 below.

Disable the demo mode by selecting the “Preferences” pull down menu and un-checking “Enable Demo
Mode”.

After demo mode is disabled, the ALP software will poll the ALP hardware. The ALP software will update
and have only “DS90UB921-Q1” under the “Devices” pull down menu.
