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 prole system, replacing the pre-installed

standard prole bracket with the included low prole bracket may be necessary.

Instruction Manual

5. (Optional) Connect an available SP4 power connection from your system power

supply to the card if additional power is required.

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.

2. AutoPlay should automatically launch and display all of the folders on the CD. If not,

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.

Instruction Manual

Verifying Installation

1. Open the Device Manager by right-clicking on Computer, and then select Manage.

In the new Computer Management window, select Device Manager from the left

window panel (For Windows 8, open the Control Panel and select

Device Manager).

2. Expand the Multifunction Adapters and Ports (COM & LPT) sections. On a successful

install, you should see 4 PCIe to Multifunction Peripheral Controller devices in the

Multifunction Adapters section, and 4 PCIe to High Speed Serial Port (COMx) devices

installed with no exclamation points or question marks.
