Anemoment LLC 10 Data Logger 422 User Manual
USB Connector
This USB port is a standard Mini-B USB connector (J8). When connected to a USB port on a
computer, the DL422 creates a virtual serial communication port to the computer.
A DL422 connected to a computer via the USB connector draws power and operates from the USB
port when V_IN is not present. A USB charge adapter can function as a power supply for the DL422.
Power Sources
The DL422 circuit board is powered by either the V_IN screw terminal or the USB connector. When
V_IN is present, no power is drawn from the USB. If V_IN is absent, the USB connector provides the
power.
Real-Time Clock Battery
A coin cell battery is used to power the Real Time Clock on the DL422 when there is no other power
source available. This is a standard CR1225 coin cell battery. If the DL422 loses time when all other
power sources are disconnected, this battery must be replaced.
