2. About the DSCF2. About the DSCF--100100

The DSCF-100 card is an isolated dual RS-232 serial card implemented with 16550 compatible
UART ASIC devices. The serial data and control lines are buffered using isolated RS-232 drivers
that allow the RS-232 interfaces to be offset from the host computer’s 0V by up to +/-50V DC to 60Hz.
This is ideal for industrial applications where the connection to remote equipment may be over
several meters of cable, which can induce significant offset voltages and cause loss of data or
unreliable transfers. The ports behave just like standard RS-232 interfaces in all other respects.
Each port has TX, RX, CTS and RTS signals, and there is a common ISOGND connection shared by
the two ports.

Industry standard baud rates up to 115.2K baud are supported, together with 16-byte deep TX and
RX FIFOs.

The DSCF-100 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 allow I/O devices and extra power for the card. The
DSCF-100 is an I/O type device and therefore requires a CF+ capable slot.

3. Installing the DSCF3. Installing the DSCF--100100

3.1 Windows CE, PocketPC (ARM, MIPS & SH3 processors)

Before inserting the card, execute the ELSERIALSETUP_POCKETPC.EXE program provided on the
Quatech Data Communication CD in the Serial Port Adapters\Drivers\Windows CE for
CompactFlash directory. After syncing, insert the DSCF-100 card and two entries will appear in a
list when you go to set up a “Connection”.

3.2 Windows 95, 98, 98SE, Me, 2000, XP

The “generic” serial drivers in these Operating Systems support the DSCF-100. Before inserting the
card, however, execute the SERIALSETUP.EXE program provided on the Quatech Data
Communication CD in the Serial Port Adapters\Drivers\Windows 95, 98, Me, 2000, XP for
CompactFlash directory.

After installation, each of the ports will appear as a COM port under the device manager. In
Windows XP, you can adjust the COM port numbering using the <Port Settings><Advanced> control
in the Device Manager by double clicking entries for the “First DSCF-100 Com Port” and “Second
DSCF-100 Com Port”.

G Under Windows XP SP1 or Windows 2000 SP4, you will need to apply a “hot fix” from Microsoft to

correct a bug that causes the ports to appear OK when they are actually non-functional. Please visit

www.quatech.com in order to obtain the hot fix and for the latest installation instructions.

4. DSCF4. DSCF--100 Register Interface100 Register Interface

The DSCF-100 behaves as a 3.3V multi-function card. There are two UART devices in the card that
will each be allocated its own I/O space and a shared IRQ. The card conforms to the PC Card Multi
Function Standard, having two sets of card configuration registers and IO BASE registers to decode
incoming I/O space “hits”. The card also fully implements the PC Card Standard defined method for
IRQ sharing, using Intr and IntrAck bits in the card’s CSRs in attribute space.

5.1 PINOUT

The DSCF-100 is supplied with a 300mm long Type49 cable that terminates with two DB9
male connectors with female screwlocks (to match the port at the back of a PC)

The pin-out below applies to the DB9 male connectors on the supplied cable, the cables are
marked Port1 and Port2.

5.2 ELECTRICAL

All figures quoted are typical parameters @ 25°C
RS-232 SIGNALS: Typical output level ±5.5V (open circuit voltages). TX, RX, CTS and

RTS are supported on each port.
UART CLOCK SPEED: 1.8432MHz, max baud rate 115.2Kbaud
ISOLATION: Isolation is defined between ISOGND and host 0V supply (metal case

of card and cable shield braid) and can be up to +/-50V, DC to 60Hz.

The two ports share a common ground (ISOGND): no isolation exists

between the two ports.
SCAVENGED POWER: The isolation driver circuit will only supply enough power to

guarantee correct RS-232 signal operation into 3Kohm loads on TX

and RTS. Using terminal equipment that scavenges power from the

RS-232 signals may not work.

UNUSED SIGNALS: If RX or CTS inputs are not used, make sure they are looped back

into TX and RTS respectively to prevent them from floating.

5.3 POWER CONSUMPTION

All figures quoted are typical parameters @ 25°C
VCC CURRENT: 35mA typical @ 3.3V

5.4 MECHANICAL

MASS: 15g typical.
FORM FACTOR: 36.4mm x 42.8mm x 5.0 mm overall size

5.5 ENVIRONMENTAL

HUMIDITY: <80% non-condensing
TEMP: 0-50°C ambient
