SD flash memory cards
The SD Flash cards are not part of the PCD3.R60x and must be
ordered separately.
It is important that the SD cards are of good quality (industry
standard, as tested by SBC). Other flash cards can also be used,
however they are not supported and are excluded from any
warranty.
To increase the lifetime, the flash cards should be filled in read-only applications
to not more than 80%. For read/write applications, it should not be more than 50%
of the disk space.
The PCD3 uses a non-standard file system (SBC FS). Therefore, the flash cards
need to be formatted before first use. This happens automatically when a new
FAT 16 flash card is inserted in the PCD3.R60x.

The card is in a so-called push-push socket (to pull and plug in),
which is located under the label clip.
It can be pulled out without switching off the PCD3.
To remove the label clip, pull off the bottom end first.
A mechanism detects the removal of the label clip. If necessary,
unsaved data is saved to the flash card. The busy LED will
light up.
Insert the flash card
When inserting the flash card, press until resistance is felt, a soft click might
sound. Relieve pressure until the card is at the same height as the slot.
Removal of the flash card
If the busy LED is off, press the card into the module housing until resistance
is felt. Decrease the pressure until the flash card slides out.
