CF slot
A Compact Flash slot is located at the front, which enables the storage medium to be replaced. In the basic module
this should only be done in switched-off state, otherwise the system may crash. The Compact Flash card can be
removed from the module for maintenance. In this way it is also possible to expand the system (only operating
system and program memory). Compact Flash cards (CF cards) are available as accessories in various sizes.
The following images illustrate the handling of the CF cards. Open the front cover. Then eject mechanism and the CF
card slot are then visible. The eject mechanism is based on the push-push principle: If the head of the mechanical
system is retracted, pushing it makes it move out of the housing. Pushing the head again will lock it back in the
housing. At the same time the card moves approx. 4 mm out of the housing, so that it can be pulled out. If the card is
pushed in (FIGURE 3), the eject mechanism will re-engage. The card is positioned correctly, if it is located approx. 1
mm lower than the front of the housing.
When the card is pushed back the eject mechanism locks again. The card is positioned correctly, if it is located
approx. 1 mm lower than the front of the housing.
Note
Type of CF slot
The Compact Flash slot is a memory interface, not an I/O type CF slot.
