Stopped Collecting Data during test? Try to Disable USB “power off” feature on your computer

Windows includes a feature that turns the power off to USB ports on a computer after a period of time in order to save power consumption. This could possibly affect the communication of the CALPlex datalogger while collecting data and result in a “communication error” message. Therefore, we recommend you change the settings for your USB ports within Windows so they are not powered-off while using CALPlex. To do this, follow the instructions below

WINDOWS XP:

Go to Control Panel
Select SYSTEM
Go to the Hardware tab
Select the Device Manager
Go to the Universal Serial Bus Controllers
For each USB Root Hub Entries right click and select Properties
Go to the Power Management Tab and un-click the “Allow Computer to turn off this Device to save power” check box. (Please un-check this check box for all USB Root Hub Ports)

WINDOWS 7:

Go to Control Panel
Select System and Security
In System section, select Device Manager
Select “Universal Serial Bus Controllers”
For each USB Root Hub Entries right click and select Properties
Go to the Power Management Tab and un-click the “Allow Computer to turn off this Device to save power” check box. (Please un-check this check box for all USB Root Hub Ports)
