Troubleshooting the Communication Port Setting
If the software does not recognize that the logger is plugged
into the USB port you should verify that the communications
port number is correct.
Note…
The port information is found on the computer under “Device
Manager.” However, depending upon your version of
Windows, the first steps below to access “Device Manager”
may differ slightly.
1. Open the “Start Menu” on the computer.
2. Select “Control Panel.”
3. Select “Device Manager.”
4. Double click on the “Ports” option.
5. The correct port will list “Prolific USB-to-Serial Comm Port”
followed by the communication port number in parentheses.
This is the port number that should be selected in the
Settings Options.
