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.

Type of CF slot The Compact Flash slot is a memory interface, not an I/O type CF slot.
