7.4 Micro-USB port
The front Micro-USB port can be used in the host-mode.
It can be used for logging data to an external media or for connecting a Wi-Fi module to the log-
ger. Wi-Fi can be used to get access to the logger over the client or to use the feature
Telemo-
tive Live View
.
USB storage:
The USB storage has to be formatted in the FAT32 file format. You could connect USB flash
drives and external hard drive up to a maximal supply current of 500 mA. External power sup-
plies must not be connected to the hard disk.
If the USB memory is pulled in the operational state, the following problems exists:
The logger is in an undefined state and will not record any data.
Only after rebooting the device behaves as expected.
The data on the USB memory can then be unreadable when it is removed during a write
operation.
If you turn off the blue PiraT Mini with the
[ON / Trigger]
button, you have 5 seconds to remove
the medium before the logger can be reawakened.
Note:
Telemotive AG recommends the testing of every external storage before using it in a
measurement. We suggest that especially USB devices with USB 3.0 are sometimes not
recognized by the system.
