Product overview 
 
Embedded PC  21 
Compact Flash slot 
A Compact Flash slot is provided at the front of module. This enables an additional Compact Flash memory medium 
(format I or II) to be operated. The change - in case of the Basic CPU module CF slot - is only allowed while the 
system is powered down - otherwise the system could crash. In case of using the CF-slot extension (CXxxxx-A001) 
the CF card can be removed after signing out the media from the system. The card can be removed for maintenance  
or to extend the system storage capacity. The Compact Flash cards (CF cards) are available as accessories with 
different storage capacities.  
As example the following pictures show the handling of the CF cards with a CX1000 system. Activating the eject 
mechanism below the slot with a screwdriver causes the card to be ejected by approx. 4 mm (FIGURE 1), so that it 
can be pulled out (FIGURE 2). 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.
