    PC or PDA. The CF+ specification extends the earlier memory-only CompactFlash interface to enable the use of I/O devices and to provide the extra power required by I/O cards. The SSCF-200/300 is an I/O type device and therefore requires a CF+ capable slot.

    4. SSCF-200/300 Register Interface For reference, the SSCF-200/300 behaves as a 5V card to the host system because Vs1 and Vs2 pins are not connected. This is to make the host default to 5V when possible, giving the highest RS- 422/485 output signals and therefore the best noise margins.

    5. Hardware Specification 5.1 PINOUT The SSCF-200/300 is supplied with a 300mm long Type 46 cable that terminates with a DB9 Male connector with female screwlocks (to match the port at the back of a PC) The pin-out below applies to both the SSCF-200/300 card and the DB9 male connector on the supplied cable (the cable is pinned one-to-one).

    Quatech CompactFlash Card User’s Manual SSCF-200/300 5.6 NOTES ON SERIAL DATA THROUGHPUT The maximum serial baud rate of 921KBits/sec does not imply that the maximum sustained throughput rate of the serial port will be as high. The actual throughput rate that can be achieved depends on many factors including the host PC speed, the serial data source’s data block size and...

    6.3 TXD AND RTS DRIVERS The RTS signal driver on the SSCF-200/300 is always enabled, regardless of the mode in which the card is to be used. The SSCF-200/300 incorporates an auto-tristate feature on the TXD signal driver. The driver is enabled only when data is in the process of being transmitted.

    6.5 RS-485 OPERATION The SSCF-200/300 can be used for both half-duplex (one twisted pair) and full-duplex (two twisted pairs) arrangements, however for half-duplex mode, the link between the TXD and RXD signals must be made externally on the DB9 connector. Also, it should be noted that the transmitted characters will always be received in this mode.
