Note 1:
The USB-3103 output voltage level defaults to 0 V whenever the output voltage range is reconfigured.
The USB-3103 output voltage level will also default to 0 V:
1) Whenever the host PC is reset, shut down or suspended.
2) If a reset command is issued to the device.
Note 2:
The duration of this output transient is highly dependent on the enumeration process of the host PC. Typically
the output of the USB-3103 is stable after 2 seconds.
