IDC Header Pinout
The internal IDC header connectors can be used in place of some / all external ports
on this card. They are labeled S1 – S4 and each corresponds to the external port of
the same number (marked on the breakout cable). Do not connect the internal and
external port of the same number simultaneously.
Installation
WARNING! PCI Express cards, like all computer equipment, can be severely damaged
by static electricity. Be sure that you are properly grounded before opening your
computer case or touching your PCI card. StarTech.com recommends that you wear
an anti-static strap when installing any computer component. If an anti-static strap is
unavailable, discharge yourself of any static electricity build-up by touching a large
grounded metal surface (such as the computer case) for several seconds. Also be
careful to handle the card by its edges and not the gold connectors.
Hardware Installation
1. Turn your computer o and any peripherals connected to the computer (i.e. Printers,
external hard drives, etc.). Unplug the power cable from the rear of the power
supply on the back of the computer and disconnect all peripheral devices.
2. Remove the cover from the computer case. Refer to documentation for your
computer system for details.
3. Locate an open PCI Express slot and remove the metal cover plate on the rear of the
computer case.
4. Gently insert the card into the open PCI Express slot and fasten the card’s bracket to
the rear of the case.
NOTE: If installing the card into a low prole system, replacing the pre-installed
standard prole bracket with the included low prole bracket may be necessary.

6. Place the cover back onto the computer case.
7. Connect the 4 Port breakout cable to the large connector on the card.
8. (Optional) If using the IDC header connections instead of some / all of the external
ports, connect them to the appropriate header(s), noting proper orientation of the
cable using the pinout provided above
NOTE: Do not connect the matching internal and external port simultaneously. The
IDC headers are labeled S1 – S4 and correspond with the numbered ports on the
breakout cable.
9. Insert the power cable into the socket on the power supply and reconnect all other
peripherals removed in Step 1.
Driver Installation
1. Upon starting Windows, if the Found New Hardware wizard appears on the screen,
cancel/close the window and insert the included Driver CD into the computer’s CD/
DVD drive.

open the Computer (My Computer in Windows XP/Server 2003) and double-click on
the CD/DVD drive.
3. Navigate to X:\IO\MOSCHIP\MCS99xx (where X:\ is your CD/DVD drive letter) and
then choose the appropriate folder for the operating system you are installing on.
4. Where applicable, choose 32bit or 64bit depending on your operating system
5. Double-click the le StnSetup.exe application and the drivers will
automatically install.
