USB connector

When not logging data, connect the USB cable to a USB port on your computer or to an external USB hub that
is connected to your computer. When connected to an active USB bus, the USB connector provides +5 V power
and communication. The voltage supplied through the USB connector is system-dependent, and may be less
than 5 V. No external power supply is required.
Due to processing limitations, you cannot log data when the device is attached to an active USB bus. For data
logging operations, connect the USB connector to the external power supply.

LED

The LED uses up to 5 mA of current. The function of the LED varies according to whether the USB-5203 is
connected to an active USB port, or when the device is logging data and connected to the external power
supply.
