OPERATION MANUAL GSM-BATCORDER
41
To 1. :
By simultaneously pressing the “ Fn ”- (
▾
) the access to the SD-card for an
external end device is cleared. As soon as the connection is established, the
message “USB CONNECTED” appears on the display.
If you want to go back to the MAIN menu you have to disconnect the USB-port first.
Therefore you press the ON/OFF-button, at the display the message
“ DISCONNECTING USB ” appears. The GSM-batcorder goes back to the main
display ( MAIN ) and can now access the SD-card again.
The USB mark stays visible, even if the external end device has no access to the
SD-card now.
To 2. :
In the standby mode (yellow display) the external end device can again have access
to the SD-card via the USB connection.
If the USB-connection has been technically established beforehand (for example to
a Raspberry Pi) the SD-card will be connected with the end device automatically.
Access to the SD-card can also be established while the GSM-batcorder is already
in standby mode by connecting an external end device. In the display “-- >USB
CONNECTED< --“ appears continuously. As long as the starting time for the
scanning mode has not been reached, the data from the SD-card can be read out by
a connected Raspberry Pi or a Computer. The connection will be interrupted from
starting time on during the whole recording session. After stopping time the USB
connection is again clear, and the connected external device can again have access
to the SD-card and for example read out the data made during the recording
session.
To 3. :
If the turned-off GSM-batcorder is connected to an active external end device via
the USB-port, it starts automatically into the USB-mode (as described under point
1.). The data from the SD-card can so be read out comfortably without using any
buttons to operate the GSM-batcorder. To turn the GSM-batcorder off again, you
only have to softly pull the USB-cable off and interrupt the USB-connection.
This possibility allows an easy and fast access to the SD-card without further
knowledge of the GSM-batcorder functions.
