JP1- COM Ports Swapping Selector: These jumpers were used to
swap Serial Ports S1-S4 and S5-S8. Please keep them at the
default factory settings since it may confuse you about the COM
Port Numbers.
JP1
Settings
No Swapping. The COM ports will be
mapped to S1 to S8 normally.
(default)
The COM ports will be swapped as
follows:
S1 S5
S2 S6
S3 S7
S4 S8
J
JP3 and JP4 - External Power Selector: These jumpers were used to
provide the external power to pin#58 of the external connector.
JP3 will enable or disable the power over the pin#58. JP4 is used
to select the power source (5V or 12V? from PCIe golden finger
or J3 AUX power connector?).
JP3
Settings
The pin#58 is connected to GND, no
power supplied to DB62’s pin#58.
(default)
The external connector DB62’
s pin#58
will be connected to a DC power
source. The power source will be
determinted by the JP4.

At this setting, please do NOT connect
the normal octopus cable supplied
with this product because the pin#58
was connected to GND
in this cable. It
will short the power source to GND and
may damage your motherboard or
power supply. This setting is designed
for your applications that need to
power from pin#58, and you need your
specical cable instead of the normal
octopus cable come with this product.
JP4
Settings
Power source is +5VDC, from J3 AUX
power connector. (default)
Power source is +12VDC, from J3 AUX
power connector.
Power source is +12VDC,
from PCI
Express golden finger (motherboard’

1. Turn the system power OFF before installation!
2. Use static electricity discharge precautions.
3. Remove the chassis cover from your computer
4. Locate an unused PCI Express slot (typically white and smaller)
and remove the corresponding slot cover from computer chassis.
5. Plug the I/O card to the unused PCI Express expansion slot and
attached the I/O card bracket to the computer chassis screw.
6. Installing the supplied DB62-to-DB9X8 octopus cable and serial
cables to your serial devices.
7. Put the chassis cover back on the computer.
8. Turn ON the power of your computer and peripherals.
9. Proceed with Software Driver Installation.
The Multi Serial I/O PCI Express card is plug-and-play so the driver
installation is quite straightforward. Please “Browse” to the correct
path on the Driver CD when Windows asking for the driver’s location.
If your card is the basic model which was shipped with the low baud
rate ( 1.8432MHZ crystal, 115.2Kbps maximum), then you are not able
to support 921.6Kbps speed. If it is the enhanced model that supports
14.7456HMZ crystal, please change the JP2 to “HI”, then go to the
COM port’s settings of Windows’ Device Manager to let it detect the
clock speed automatically.

Note: To check if your card supports high baud rate of
921.6Kbps, please take a look at the crystal Y1 on the card’s PC board,
the basic model equipped with 1.8432MHZ and the enhanced model
equipped with a 14.7456MHZ oscillators. The basic model is the current
main model. For enhanced model, you need go to Windows’ COM
port Properties to detect this input clock automatically and fit this
clock value (see the software setup for more details)
6.1 Windows 2000, XP
In the Windows COM port properties as the following figure, select
〝
Data rate
〞
and click on
〝
Detect Crystal Frequency
〞
The
〝
Crystal Frequency
〞
settings will be set to
〝
14.7456MHZ
〝
,
then click
〝
OK
〞
The settings will be saved by Windows. You don’t need to
configure it again whenever you restart the system
