2. About the SSCF-200/300

The SSCF-200/300 is a RS-422/485 serial card with a 16550 compatible UART ASIC device. The
serial data and control lines are buffered using ESD protected RS-422/485 drivers.

Industry standard baud rates up to 115.2K baud are supported, together with 16-byte deep TX and
RX FIFOs. A small switch located at the back edge of the card can be used to select a “x1” or “x8”
baud rate multiplier. This feature enables up to 921KBaud operation without requiring special
device drivers on the host (in x8 mode you simply multiply the setting shown on the host by 8 to get
the real serial data rate e.g. 19200 Baud set on host with x8 mode gives 153600Baud true rate in
hardware). See section 5 for the switch settings.

The SSCF-200/300 conforms to the industry standard CompactFlash+ interface that allows
connection of peripherals to the system bus of a laptop, handheld 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.
