If an ALARM is present ( ) and the
Clear alarm by pressing STOP button
function is enabled, you will
need to clear the alarm first before you can stop the logger. Please see
information. In this case, a tick will be shown for the alarm status once the logger has stopped.
Plugging the VFC400-WiFi into a USB port
What happens when you plug your VFC400-WiFi into a USB port depends on the operating system of the
computer, the settings made during configuration and whether or not Control Solutions VTMC is running.
Microsoft Windows
Up to four drivers will now be installed, depending on the VFC400-WiFi's configuration.
All drivers are part of the operating system and will typically not require administrator privileges for your
computer.
1.
Mass Storage Device Driver
2.
LogTag Mass Storage USB Device Driver
These two devices are required so you can access the data files in the same way as a USB memory
stick. These drivers will not be installed if the VFC400-WiFi does not generate files.
3.
USB Input Device (HID) Driver
This device is used for communication to Control Solutions VTMC and its driver will always be installed,
even if Control Solutions VTMC is not present on the computer.
4.
USB Composite Device Driver
This driver signals that multiple devices are involved when plugging in a VFC400-WiFi.
If you have configured the VFC400-WiFi to
generate files
, these will be created every time you plug the logger
into the USB port. While the file creation takes place, the display shows
bUSy
instead of the current time.
Once the files are generated, a new drive or mounted device will appear. The device name will be created from
the serial number of the VFC400-WiFi.
If you have disabled file generation during configuration, no drive will appear.
USB communication can interfere with temperature measurement. While a VFC400-WiFi is plugged
into a PC's USB port, occasionally a scheduled temperature reading is not taken. The graph will
display a gap and the data list will show --- followed by the # symbol. This does not apply when the
logger is connected to a USB power supply.
macOS, OSX and Linux
Typically in these operating systems a new drive will be mounted, from which you can open the PDF file. You
will not be able to configure the VFC400-WiFi using either of these operating systems, unless you use
virtualization software such as VMWare Fusion, Parallel Desktop or Virtualbox to create a hosted Windows
environment. You need to discuss these options with your network administrator.
