JRexplus LX User's Guide
13.2 Compact Flash Card Interface
The same primary P-ATA channel is realized as a CF card interface, also capable of UDMA. The interface has
jumper options to be either a master or slave device. If for example the Compact Flash card is set to master
only a slave device can be connected to the 44 pin IDE connector.
13.2.1 Connector
The CF card interface is available through the standard CF connector X21 (50 pins).
