Calling the file manager
Press the PGM MGT key: the TNC displays the file
management window (Figure at right shows the
factory default setting. If the TNC displays a different
screen layout, press the WINDOW soft key.)
The narrow window on the left shows the available drives and
directories. Drives designate devices with which data are stored or
transferred. One drive is the internal memory of the TNC. Other drives
are the RS232, RS422, Ethernet and USB interfaces, which you can
used, for example, to connect a personal computer or other storage
device. A directory is always identified by a folder symbol to the left
and the directory name to the right. A subdirectory is displayed to the
right of and below its parent directory. A box with the + symbol in front
of the folder symbol indicates that there are further subdirectories,
which can be shown with the –/+ key or ENT.
The wide window on the right shows you all files that are stored in the
selected directory. Each file is shown with additional information,
illustrated in the table below.
