Connecting the logger
The U-Series logger requires an Onset-supplied USB interface cable to
connect to the computer. If possible, avoid connecting at temperatures
below 0°C (32°F)
or above 50°C (122°F).
1. Plug the large end of the USB interface cable into a USB port on the
computer.
2. Plug the small end of the USB interface cable into the side of the
logger as shown in the following diagram.
3. Load and use logger software to operate the logger (see software
manual).
