1.3.7 CompactFlash Card Interface

Information about Usage of CompactFlash® Cards!
A correct functionality of the CompactFlash interface can only be ensured by usage
of CompactFlash cards with guaranteed SSD-properties.
esd therefore recommends to use one of the listed SLC-cards:
- Western Digital SiliconDrive II (e.g. 4GB: SSDC04G-4600)
- Cactus CompactFlash 303 Series (e.g. 4GB: KC4GR-303)
- Swissbit C-320 (e.g. 4GB: SFCF4096H1BO2TO-C-D1-523-SMA)
Only with this CF-cards the correct function of the CF-card interface is ensured and
support for the devices is provided.
esd will evaluate more CF-cards and release them on success.

1.3.8 Software Support

The boot monitor U-Boot* is stored in the Flash  memory. This makes it possible for the CPCI-405 to
boot with various operating systems from the network, the local Flash memory or the Compact Flash
memory. 
The operating systems Linux and VxWorks are available with according drivers for the local interfaces.
Further operating systems are available on request.
Furthermore the CAN-transmission protocols CANopen and DeviceNet and a local WEB-server are
available.
