Thank you for purchasing this 4-Port RS232 Serial PCI Card. It is an
add-in card that connects to a PC or server via the PCI Bus to provide
high-speed serial connectivity. The serial ports are fully compatible
with RS232 standard by the complete bundled drivers.
Each port supports 15KV ESD protection feature. It provides an ideal
solution for most critical applications.
Features:
Fully PCI Bus 2.3 and PCI Power Management 1.1 Compliant
Supports 4 RS232 serial ports over a PCI Slot
Supports low profile form factor by an optional short bracket
Fully 16C1050 High performance UART channels
±15kV IEC1000-4-2 ESD Protection for RS-232 I/O's
Supports both 3.3V and 5V PCI Slots
Baud rate up to 921.6 Kbps in a asynchronous mode
256-byte deep FIFO per transmitter and receiver
Supports 5V or 12V over DB44 connector pins, the
Fan out Octopus Cable Supplies it to DB9 Connectors
Software/Hardware Flow Control & Xoff Re-Transmit Function
Supports Win98/ME, 2K, 2003, XP, Vista, Win7, 8, 8.1 and Linux

JP3 – PME Enable/Disable Jumper: This jumper provides an option to
enable the PCI card to wake up the system by its serial ports. The
default was set at “DIS” (disabled).

DB9 male connector has an option to supply DC power to its Pin-9.
Pin number 9 of the DB9 connector was defined for RS232 RI (Ring
Indicator) signal. Since some applications do NOT use this signal, in
this case, Pin-9 can be used to deliver DC power for the serial
devices. This product provides 2 settings for the power, +5V and
+12V. The default factory setting was set at “RI”, i.e. no power
supplied on the DB9M connector’s pin-9.

JP2 – 5V and 12V Power Source Selection Jumper: To supply power
to Pin-9 of each DB9 connector, you need +5V and +12V power
source. Both can be selected from either PCI golden fingers or
from J2 AUX Power connector instead. If you select from J2, then
you need connect a power cable to connect it to your system
power supply.

JP1 – UART Power: This jumper is used to select the power for the
RS232 transceivers. The default setting is “+3.3V”. Due to some old
RS232 devices need higher swing voltage level, in this case,
please move the jumper to “+5V” instead.

Note:
PLEASE DO NOT LET WINDOWS AUTO SEARCH THE DRIVERS ON THE CD, it
will cause problems because the INF files will be conflict in this case.
Instead, please browse to the correct location (folder) manually to
make sure the correct drivers are chosen and installed correctly.
